The height of the square pyramid with base area 225 cm² and volume 300cm³ is equal to 4 centimeters.
Area of the base of square pyramid = 225 centimeters squared
Volume of the square pyramid = 300 centimeters cubed
Using the formula for the volume of a square pyramid,
V = (1/3) × B × h
where V is the volume,
B is the area of the base,
and h is the height of the pyramid.
Substitute this value into the formula we have,
⇒ 300 = (1/3) × 225 × h
Simplifying the equation , we get,
⇒ 900 = 225 × h
Dividing both sides by 225, we get,
⇒ h = 4
Therefore, the height of the square pyramid is 4 centimeters.

State the domain and range of the function.
Stats the end behavior of the function.
Answer:
7.D
8.A
Step-by-step explanation:
For the function f(x) = √x+2+5:
(D) D= {x|x≥2}, R= {y|y≥5}
The domain is restricted to x values greater than or equal to 2 because the function contains the square root of x+2, which cannot be negative. The range starts at y = 5 because the lowest possible output of the function is √2+2+5 = 5.
(A) f(x)+∞o as x→ +∞o; f(x) +∞ as x――∞
As x approaches positive infinity, the output of the function approaches infinity as well. As x approaches negative infinity, the function is undefined since it involves taking the square root of negative numbers. However, the limit of the function as x approaches negative infinity from the right is positive infinity.

Equipment acquired on January 8 at a cost of $212,000 has an estimated useful life of 15 years, has an estimated residual value of $14,000, and is depreciated by the straight-line method.
a. What was the book value of the equipment at December 31 the end of the fifth year?
b. Assume that the equipment was sold on April 1 of the sixth year for $105,800.
1. Journalize the entry to record depreciation for the three months until the sale date.
2. Journalize the entry to record the sale of the equipment.
The journal entry to record the sale of the equipment would be:Cash $105,800,Loss on Sale of Equipment $35,650,Equipment $212,000
Accumulated Depreciation $66,000
How to solve the question?
a. To calculate the book value of the equipment at December 31 of the fifth year, we need to determine the accumulated depreciation for the first five years. The annual depreciation expense is calculated as follows:
Depreciation Expense = (Cost - Residual Value) / Useful Life
Depreciation Expense = ($212,000 - $14,000) / 15
Depreciation Expense = $13,200 per year
The accumulated depreciation for five years is therefore:
Accumulated Depreciation = Depreciation Expense x Number of Years
Accumulated Depreciation = $13,200 x 5
Accumulated Depreciation = $66,000
The book value of the equipment at December 31 of the fifth year is calculated as follows:
Book Value = Cost - Accumulated Depreciation
Book Value = $212,000 - $66,000
Book Value = $146,000
b.
To record depreciation for the three months until the sale date, we need to calculate the depreciation expense for the sixth year. The annual depreciation expense remains the same at $13,200, but since the equipment was sold on April 1, we need to prorate the depreciation for the first three months of the year.
Depreciation Expense for the Sixth Year = Depreciation Expense x (Months Remaining / 12)
Depreciation Expense for the Sixth Year = $13,200 x (9 / 12)
Depreciation Expense for the Sixth Year = $9,900
The journal entry to record depreciation for the three months until the sale date would be:
Depreciation Expense $9,900
Accumulated Depreciation $9,900
To record the sale of the equipment, we need to compare the sale price to the book value of the equipment at the time of the sale.
The book value of the equipment at the time of the sale is calculated as follows:
Book Value = Cost - Accumulated Depreciation
Book Value = $212,000 - ($13,200 x 5.25)
Book Value = $141,450
Since the sale price of $105,800 is less than the book value of $141,450, we need to record a loss on the sale of the equipment. The journal entry to record the sale of the equipment would be:
Cash $105,800
Loss on Sale of Equipment $35,650
Equipment $212,000
Accumulated Depreciation $66,000
The cash received from the sale is debited, and the difference between the sale price and the book value is recorded as a loss on the sale of the equipment. The equipment and its accumulated depreciation are removed from the books.

Find the surface area of the figure. Round to the nearest hundredth when necessary.
The surface area of the cylinder is approximately 3015.93square inches when rounded to the nearest hundredth.
What is the Surface Area of a Cylinder?To find the surface area of a cylinder, we need to add the areas of the top and bottom circles, and the area of the lateral surface, which is the curved part of the cylinder.
The formula for the surface area of a cylinder is:
S.A. = 2πr² + 2πrh
where r is the radius of the cylinder, h is the height, and π is approximately equal to 3.14.
Given that the diameter is 32 inches, we can find the radius by dividing by 2:
r = d/2 = 32/2 = 16 inches
Now we can substitute the values into the formula and simplify:
S.A. = 2πr² + 2πrh
S.A. = 2π(16)² + 2π(16)(14)
S.A. = 2π(256) + 2π(224)
S.A. = 512π + 448π
S.A. = 960π
To approximate the answer to the nearest hundredth, we can use the value of π rounded to two decimal places (3.14):
S.A. ≈ 960(3.14)
S.A. ≈ 3015.93 square inches

Write as a logarithm with a base of 4. -4
Answer:
4 cannot be written as a logarithm with a base of 4. A logarithm is an exponent that tells us how many times we need to multiply a base by itself to get a certain number. For example, log2(8) = 3 because 2^3 = 8. We can write this as an equation: logb(x) = y means b^y = x.
-4 cannot be written as a logarithm with a base of 4 because there is no exponent that can make 4 equal to -4. In other words, there is no y such that 4^y = -4. This is because any positive number raised to any power will always be positive. Therefore, log4(-4) is undefined or does not exist.
Therefore, -4 cannot be written as a logarithm with a base of 4.

Dean ran 2.3 fewer kilometers than Sam. If Dean ran 6.8 km, how far did Sam run? A 2-column table with 4 rows. Column 1 is labeled Situation with entries increasing, difference, finding part of a total, sharing or grouping. Column 2 is labeled Operation with entries +, minus, times, divided by. Select all that apply. You know the difference in the distances the boys ran, so this is a subtraction problem. You are finding the total distance the boys ran, so this is an addition problem. Dean ran part of the distance Sam ran, so this is a multiplication problem. The correct equation is s + 2.3 = 6.8. The correct equation is s – 2.3 = 6.8. The correct equation is 2.3s = 6.8.
The correct equation to use is "s - 2.3 = 6.8", where s represents the distance Sam ran.
What is distance?Distance is a measurement of how far apart two objects or points are from each other. It is usually measured in units such as meters, kilometers, miles, or feet. Distance can refer to physical space between two points, or it can be used to describe the extent of an abstract concept, such as a difference in opinion or a cultural divide.
According to question:The Situation column should have two entries: "finding part of a total" and "difference".
The Operation column should have only one entry: "minus".
The right formula is "s - 2.3 = 6.8", where s stands for the distance Sam ran.
To solve for s, we can add 2.3 to both sides of the equation:
s - 2.3 + 2.3 = 6.8 + 2.3
s = 9.1
Therefore, Sam ran 9.1 kilometers.
So, the Situation entries are: "difference" and "finding part of a total".
The Operation entry is: "minus".

Solve the system of equations using substitution. y = 3x y = 6x + 3 (2, 15) (1, 3) (−1, −3) (−2, −6)
We are given the system of equations:
y = 3x
y = 6x + 3
We can use substitution to solve this system. Since both equations are equal to y, we can set them equal to each other:
3x = 6x + 3
Subtracting 3x from both sides, we get:
0 = 3x + 3
Subtracting 3 from both sides, we get:
-3 = 3x
Dividing both sides by 3, we get:
x = -1
Now that we know x, we can use either equation to find y. Let's use the first equation:
y = 3x = 3(-1) = -3
Therefore, the solution to the system of equations is (-1, -3).
To check our solution, we can substitute these values back into both equations:
y = 3x gives us -3 = 3(-1), which is true
y = 6x + 3 gives us -3 = 6(-1) + 3, which is also true
Therefore, our solution is correct.
We can also plug in the other given points to check that they do not satisfy both equations, which means they are not solutions to the system.

Find the number of different arrangements of the 8 letters in the word DECEIVED, in which two Ds are together and the three Es are not all together (i.e. maximum two Es next to each other).
The eight letters in the word DECEIVED may be arranged in 4200 distinct ways, with two Ds grouped together and three Es not all together.
The following approach may be used to determine how many different ways there are for the eight letters in the word DECEIVED to be arranged such that two Ds are together and three Es are not altogether:
Treat the two Ds as a single object, which we can call DD. Now we have 7 objects to arrange: DD, E, E, C, V, I, and E.First, we count the total number of arrangements of these 7 objects, without considering any restrictions. This is simply the number of permutations of 7 objects, which is 7! = 5040.Next, we count the number of arrangements in which the three Es are all together. We can treat the three Es as a single object, which we can call EEE. Now we have 6 objects to arrange: DD, EEE, C, V, I, and an extra E. The number of arrangements of these objects is 6!, since we can treat the EEE as a single object.However, we have overcounted the arrangements in which the two Es are together with the EEE object. To correct for this, we can treat the two Es as a single object, which we can call EE. Now we have 5 objects to arrange: DD, EEE, EE, C, V, and I. The number of arrangements of these objects is 5!, since we can treat the EEE and EE as single objects.Therefore, the number of arrangements in which the three Es are not all together is the difference between the total number of arrangements and the number of arrangements in which the three Es are all together, minus the number of arrangements in which the two Es are together with the EEE object:7! - 6! - 5! = 5040 - 720 - 120 = 4200
Therefore, there are 4200 different arrangements of the 8 letters in the word DECEIVED, in which two Ds are together and the three Es are not all together.

a) Calculate the scale factor from shape A to shape B. b) Find the value of t. Give each answer as an integer or as a fraction in its simplest form.
Answer:
a) The scale factor is [tex]\frac{4}{5}[/tex]
b) [tex]t=5\frac{3}{5}[/tex]
Step-by-step explanation:
The scale factor from shape A to shape B is the value that is multiplied by the side measures of shape A to arrive at the side measures of shape B.
In other words, 5 times a certain value is 4, 15 times a certain value is 12. and 7 times a certain value is t.
Let's start by calling our "certain value" k.
[tex]5k=4=\\k=\frac{4}{5}[/tex]
Let's check 15 to make sure k is 4/5, like so:
[tex]15(\frac{4}{5})=\\\frac{60}{5} =\\12[/tex]
Since 15 times 4/5 is twelve, our initial answer was correct.
So, the scale factor, or k, is 4/5.
Following this logic, we know that 7 multiplied by the scale factor is equal to t.
Let's set up an equation and solve for t:
[tex]7(\frac{4}{5} )=t=\\\frac{28}{5} =t=\\5\frac{3}{5} =t[/tex]
So, [tex]t=5\frac{3}{5}[/tex]

Suppose a(x) takes integers as inputs (so x=-4 is in the domain, but x=1/2 isn't, for example) and returns 1 if x is odd and 0 otherwise. Is a(x) a function? Is it a one-to-one function? Why?
Because it gives exactly one output value for each input value, a(x) is a function, hence the answer is yes. Since several input values might result in the same output value, it is not a one-to-one function.
Describe function.A mathematical item called a function accepts an input and creates an output. It looks like an apparatus with an input and an output. A formula or a graph can both be used to express a function. For instance, the function f(x) = x² returns the square of an input x as output.
Because it gives exactly one output value for each input value, a(x) is a function, hence the answer is yes. Since several input values might result in the same output value, it is not a one-to-one function. A(x) is not one-to-one, for instance, because a(1) and a(3) are both equal to 1.

From a standard deck of 52 cards, in how many ways can 7 cards be drawn?
there are 133,784,560 ways to draw 7 cards from a standard deck of 52 cards.
How to solve the question?
The number of ways to draw 7 cards from a standard deck of 52 cards can be calculated using the combination formula, which is:
C(52, 7) = 52! / (7! * (52-7)!)
where "!" represents the factorial function.
To simplify this expression, we can use the property that n! / k! = n * (n-1) * (n-2) * ... * (n-k+1) for positive integers n and k such that k ≤ n.
Using this property, we can rewrite the above expression as:
C(52, 7) = (52 * 51 * 50 * 49 * 48 * 47 * 46) / (7 * 6 * 5 * 4 * 3 * 2 * 1)
Simplifying this expression, we get:
C(52, 7) = 133,784,560
Therefore, there are 133,784,560 ways to draw 7 cards from a standard deck of 52 cards.
To understand why this is the case, we can think of each draw as a separate event with no replacement. The first card can be drawn in 52 ways, the second card can be drawn in 51 ways (since one card has already been drawn), the third card can be drawn in 50 ways (since two cards have already been drawn), and so on. Therefore, the total number of ways to draw 7 cards is the product of the number of ways to draw each individual card, which is 52 * 51 * 50 * 49 * 48 * 47 * 46. However, since the order in which the cards are drawn does not matter, we need to divide by the number of ways to arrange 7 cards, which is 7 * 6 * 5 * 4 * 3 * 2 * 1 (i.e., 7 factorial). This gives us the final answer of 133,784,560.

The confidence interval can be expressed as a trilinear inequality: 82.9% < p < 95.7%.
The confidence interval in interval form is (0.1864, 0.3026).
How to calculate confidence interval?The given confidence interval, 89.3% ± 6.4%, means that we are 89.3% confident that the true value of the population parameter lies within a range of 6.4% above and below the sample estimate.
To express this in the form of a trilinear inequality, first find the upper and lower bounds of the interval.
Upper bound = 89.3% + 6.4% = 95.7%
Lower bound = 89.3% - 6.4% = 82.9%
Therefore, the confidence interval 89.3% ± 6.4% can be expressed in the form of a trilinear inequality as:
82.9% < p < 95.7%

The radius of the wheel is 1.2 feet. What is the distance traveled when the wheel turns 20 time?
The distance traveled by the wheel when it turns 20 times is 150.7964 feet.
What is circumference?
The circumference of a wheel can be calculated as:
Circumference = 2 x π x radius
where π (pi) is a mathematical constant approximately equal to 3.14159.
The distance traveled by a wheel when it turns is equal to the circumference of the wheel multiplied by the number of times it turns.
Given that the radius of the wheel is 1.2 feet, the circumference of the wheel is:
Circumference = 2 x π x radius
Circumference = 2 x 3.14159 x 1.2
Circumference = 7.53982 feet (rounded to 5 decimal places)
Therefore, each time the wheel turns, it travels a distance of 7.53982 feet. To find the distance traveled when the wheel turns 20 times, we can multiply the distance traveled each time by the number of times the wheel turns:
Distance traveled = Circumference x Number of turns
Distance traveled = 7.53982 feet x 20
Distance traveled = 150.7964 feet (rounded to 4 decimal places)
Therefore, the distance traveled by the wheel when it turns 20 times is 150.7964 feet.

Worked example
The company sent 1225 items by second class post.
The ratio of the number of letters sent to the number of packets sent was 8:27
fraction numerator 2 over denominator 7 end fractionof the packets sent were in the weight range 0 – 100 g.
The other packets sent were in the weight range 101 – 250 g.
Work out the total cost of sending the 1225 items by second class post.
Calculation
The total number of items sent was 1225, to proportion the items according to the ratio we first need to work out how many items there are in 1 part of the ratio. So in this example the ratio is 8:27 so there are a total of 8 + 27 = 35 parts.
So, dividing 1225 by 35 will give us the number of items per part of the ratio
1225 over 35 equals 35
We can now multiply each part of the ratio by the number of items per part to give us the number of letters and packets
letters = 35 space cross times space 8 space equals
Total Letters =
Answer for part 1
packets = 35 space cross times space 27 space equals
Total Packets =

We know that the ratio of small to large packets is 2:7, so to calculate the number of small packets we need to first work out the number of parts of the ratio adding 2 and 7 together
This gives us 2+7=9
We can now multiply each part of the ratio by the number of items per part to give us the number of small and large packets
For small packets fraction numerator 2 over denominator 9 end fraction
No. packets 0 - 100g =
Answer for part 4
For large packets fraction numerator 7 over denominator 9 end fraction
No. packets 101 - 250g =
Answer for part 5
We can now use these figures to calculate the cost for each type of packet
Cost of packets 0 - 100g =£
Answer for part 6
Cost of packets 101 - 250g =£
Answer for part 7
And we can now calculate the total cost of letters and packets
Total cost of letters and packets =£

Tje number of items in the ratio 8:27, proportioned according to the total number of items sent (1225), is 280 items in the 8 part and 945 items in the 27 part.
How to calculate the valueTo find out how many items there are in 1 part of the ratio, we need to add together the two parts of the ratio. In this case, 8+27 = 35.
To proportion the items according to the ratio, we need to divide the total number of items (1225) by the number of parts in the ratio (35).
This gives us:
1 part of the ratio = 1225 / 35 = 35
To find out how many items there are in each part of the ratio, we need to multiply this value by the corresponding part of the ratio.
For the part that corresponds to 8, we have:
8 parts of the ratio = 8 x 35 = 280 items
For the part that corresponds to 27, we have:
27 parts of the ratio = 27 x 35 = 945 items
Therefore, the number of items in the ratio 8:27, proportioned according to the total number of items sent (1225), is 280 items in the 8 part and 945 items in the 27 part.

1. The value of Angle STR is 19°
2. The value of arc ST is 134°
What Is circle geometry?A circle is a special kind of ellipse in which the eccentricity is zero and the two foci are coincident.
Part of circle theorem states that: The angle in the same segment are equal.
1. Therefore the value of angle STR is calculated as;
= 180- ( 90+71)
= 180- 161
= 19°
2. The value of arc ST is calculated as;
Since arc SR = QR = 46°
representing the value of arc ST by x
therefore,
46+46+x+x = 360
92 +2x = 360
2x = 360-92
2x = 268
divide both sides by 2
x = 268/2

Cuantos subconjuntos tiene A={a, r, i, t, m, e, t, i, c, a}
The number of subsets that the set has are 128 subsets.
How to find the number of subsets?First, let's remove the duplicates from the set A. The distinct elements in set A are:
A = {a, r, i, t, m, e, c}
Now, we can find the number of subsets. For each element in the set, we have two choices: either it is included in the subset, or it is not. Therefore, there are 2^n subsets for a set with n distinct elements.
In our case, n = 7, so there are 2^7 = 128 subsets for the given set A.
