Need answers ASAP

Answers

Answer 1

The dimensions of the strongest beam are 27 inches x 13.5 inches.

What is a dimension?

In general, dimension refers to a measurable extent of a physical quantity, such as length, width, height, depth, or time. These dimensions provide a framework for describing and measuring objects and events in the physical world. In geometry, dimension are refers to the number of coordinates needed to specify a point in a space. In physics, the concept of dimension is used to describe the properties of space and time.

We know that the strength of the beam is directly proportional to its width multiplied with the square of its height. Let's call the width of the beam "w" and the height "h". Then we can write the strength of the beam as:

S = kwh², where "k" is the constant of proportionality.

We want to find the dimensions of the strongest beam, which means we want to find the values of "w" and "h" that will maximize the strength "S". To do this, we need to find the maximum value of the function S = kwh² subject to the constraint that the diameter of the log is 18 inches.

The diameter of the log is equal to the width of the beam plus twice the height of the beam:

d = w + 2h

Since the diameter of the log is 18 inches, we can write:

w + 2h = 18

or

w = 18 - 2h

Substituting this expression for "w" into the equation for the strength of the beam, we get:

S = k × w(18-2h) × h²

Expanding and simplifying this expression, we get:

S = 36kh³ - 2kh⁴

To find the maximum value of S, we take the derivative of S with respect to h and set it equal to zero:

dS/dh = 108kh² - 8kh³ = 0

Simplifying this expression, we get:

h²(108 - 8h) = 0

This equation has two solutions: h = 0 and h = 13.5.

Since a beam with height equal to zero would have zero strength, we reject the solution h = 0. Therefore, the maximum strength is achieved when h = 13.5 inches.

To find the corresponding width, we can use the equation we derived earlier:

w = 18 - 2h = 18 - 27 = -9

Since the width of the beam cannot be negative, we reject this solution as well.

Therefore, the required dimensions of the strongest beam are:

Width = 2h = 2(13.5) = 27 inches

Height = h = 13.5 inches

A rectangle has a length of x + 4 cm and a width of 2x − 7 cm.
(a) If the perimeter is 36cm, what is the value of x?
(b) What is the area of this rectangle

Answers

Answer:

See below!

Step-by-step explanation:

Given data:

Length = x + 4 cm

Width = 2x - 7 cm

Part a)

Perimeter:

Sum of all sides of a shape is called perimeter.Perimeter of rectangle = 2(length) + 2(width)

Put the given data.

36 = 2(x + 4) + 2(2x - 7)

Distribute

36 = 2x + 8 + 4x - 14

Combine like terms

36 = 2x + 4x + 8 - 14

36 = 6x - 6

Add 6 to both sides

36 + 6 = 6x

42 = 6x

Divide both sides by 6

42/6 = x

7 = x

OR

x = 7Part b)Area of rectangle = length × width

Area = (x + 4)(2x - 7)

Put x = 7

Area = (7 + 4)(2(7) - 7)

Area = 11(14 - 7)

Area = 11(7)

Area = 77 cm²

[tex]\rule[225]{225}{2}[/tex]

Answer: (a) x=7

(b) area of this rectangle = 77[tex]cm^{2}[/tex]

Step-by-step explanation:

(a) the perimeter of a rectangle = 2 * [  l + b ]

36 = 2 * [ (x + 4) + (2x - 7) ]

36 / 2 = x + 4 + 2x - 7

18 = 3x -3

18 + 3 = 3x

21 = 3x

x = 7

(b) the area of a rectangle = l * b

l = x + 4 = 11cm

b = 2x -7 = 7cm

therefore, 11cm * 7cm = 77[tex]cm^{2}[/tex]

deal?
OA. 9
B. 6
O C. 5

Answers

Let x be the number of hours of car sharing per year. Then the cost of using Company A is given by:

Cost of Company A = $125 + $7x

The cost of using Company B is given by:

Cost of Company B = $110 + $10x

We want to find the minimum number of hours of car sharing per year such that Company A is a better deal than Company B. In other words, we want to find the value of x such that:

Cost of Company A < Cost of Company B

125 + 7x < 110 + 10x

15 < 3x

5 < x

So the minimum number of hours of car sharing per year to make Company A a better deal is 6 hours. Therefore, the answer is B!!

A mirror is placed 45 feet from the base of a waterfall by a hiker. The hiker walks backwards until they are 7.5 feet from the mirror. Determine how tall the waterfall is if the hiker is 6 feet tall.

36 ft
39.5 ft
56.25 ft
72 ft

Answers

If the hiker is 6 feet tall, then the height of the waterfall will be: 32.57 feet.

How to determine the height of the waterfall

We can solve this problem using similar triangles. Let us call the height of the waterfall "h". Then, the distance from the base of the waterfall to the mirror is also "h" (since the mirror reflects the top of the waterfall down to the hiker's eye).

Using similar triangles, we can set up the following proportion:

(h + 6 feet) / 45 feet = 6 feet / 7.5 feet

Cross-multiplying and simplifying, we get:

h + 6 feet = 270 feet / 7

h + 6 feet = 38.57 feet

h = 32.57 feet

So, the correct height given the variables is 32.57 feet.

Answer:

36 ft

Step-by-step explanation:

We can use the concept of similar triangles to solve this problem. The ratio of the heights of the hiker and the waterfall is the same as the ratio of their distances to the mirror.

Given:

Distance from mirror to waterfall = 45 feet

Distance from mirror to hiker = 7.5 feet

Hiker's height = 6 feet

Let's set up a proportion:

(Hiker's height) / (Hiker's distance to mirror) = (Waterfall's height) / (Waterfall's distance to mirror)

Substitute the given values:

6 / 7.5 = (Waterfall's height) / 45

Now solve for the height of the waterfall:

Cross-multiply:

6 * 45 = 7.5 * (Waterfall's height)

270 = 7.5 * (Waterfall's height)

Divide by 7.5:

Waterfall's height = 270 / 7.5

Waterfall's height = 36 feet

So, the height of the waterfall is 36 feet.

Among the provided options, the correct answer is:

what is the cosine of angle b

Answers

For the given right angled triangle cosine of angle B is 5√89/89.(option A).

What is right angled triangle?

It is a particular type of triangle having one angle is 90° or right angle. The adjacent sides of the right angle are called base and the perpendicular and the opposite side of 90° is called hypotenuse.

The given triangle is the right angled triangle. The three sides of a right angled triangle are called base, perpendicular and hypotenuse.

In the given figure base=  5 inches and perpendicular = 8 inches

By Pythagoras theorem at first we will find out the hypotenuse. Let the hypotenuse= c inches

For any right angled triangle,

(perpendicular)² +(base)²= (hypotenuse)²

⇒ (8)² + (5)² = (c)²

⇒ 64+ 25 = c²

⇒ c² =89

⇒ c= ±√89

As hypotenuse cannot be negative

So hypotenuse = √89 inches.

Now to find cosine of angle B that is cos B we will use the trigonometric function.

cos B= Adjacent side/ hypotenuse

         = 5/√89

        = 5√89/89 [ Multiplying the numerator and the denominator by √89 ]

Hence, cosine of angle B is 5√89/89.

suppose that a and b are positive for which log9(a) = log15(b) = log25(a + 2b). What is the value of b over a​

Answers

Thus, the value of b over a for the given logarithmic function is obtained as: b/a = 1 + √2.

Explain about the logarithmic function:

The logarithm is exponentiation's opposite function in mathematics. This indicates that the exponent with which b must be raised in order to obtain a number x is the logarithm of x to the base b.

A base must still be raised to a certain exponent or power, or logarithm, in order to produce a specific number. If bˣ = n, then x is the logarithm of n to the base b, which is expressed mathematically as x = logb n.

Given that:

log9(a) = log15(b) = log25(a + 2b)

Let ,  log9(a) = log15(b) = log25(a + 2b) = x

Then,

log9(a) = x (taking antilog)

log3²(a) = x

a = 3²ˣ

log15(b) = x  (taking antilog)

log(3*5)(b) = x

b = 3ˣ.5ˣ

log25(a + 2b) = x   (taking antilog)

log5²(a + 2b) = x

a + 2b = 5²ˣ

Now,

b²/a = a + 2b

(b/a)² = 1 + 2*(b/a)

If t = b/a, then t² - 2t -1 = 0

On factorization:

t = 1 ± √2 ( a and b are positive integer)

b/a = 1 + √2

Thus, the value of b over a for the given logarithmic function is obtained as: b/a = 1 + √2.

A rectangular room is 2 feet
longer than it is wide. Its area is 168 square feet. Set this up as a quadratic equation

Answers

Answer:

x = -14 and x = 12

Step-by-step explanation:

Let x be the width of the rectangular room in feet. Then, according to the problem, the length of the room is 2 feet longer than the width, or x + 2 feet.

The area of a rectangle is given by the formula A = length × width, so we have:

A = (x + 2) × x = x^2 + 2x

We are also given that the area of the room is 168 square feet, so we set A = 168 and get:

x^2 + 2x = 168

This is a quadratic equation in standard form, where 1x^2 + 2x - 168 = 0. We can solve this equation by factoring or using the quadratic formula. This will give us the value(s) of x, which represents the width of the room. Once we have the width, we can find the length by adding 2 feet to it.

The rectangular coordinates of a point are (17,0). Find the polar coordinates.

Answers

The polar coordinates of the point (17,0) are (r,θ) = (17,0). This means that the point is located on the positive x-axis, at a distance of 17 units from the origin.

To find the polar coordinates of a point given in rectangular coordinates, we need to use the following formulas:

r = √(x² + y²)

θ = tan⁻¹(y/x)

where r is the distance from the origin to the point, and θ is the angle between the positive x-axis and the line connecting the origin and the point.

In this case, the point is (17,0), so x = 17 and y = 0. Using the formulas above, we get:

r = √(17² + 0²) = 17θ = tan⁻¹(0/17) = 0

In polar coordinates, a point is represented by an ordered pair (r,θ), where r is the distance from the origin to the point, and θ is the angle between the positive x-axis and the line connecting the origin and the point, measured in radians.

Years are a unit of time measurement used to quantify the duration of one complete orbit of the Earth around the sun. A year consists of 365 days, except in a leap year when an extra day is added. The concept of a year is used in various fields, including astronomy, geology, and history.

According to the given information

(a) Let's first find the total ratio of their ages:

1 + 3 = 4

So Jack's share will be:

1/4 x £60 = £15

And Jill's share will be:

3/4 x £60 = £45

Therefore, Jill receives £45.

(b) The next Christmas, Jack will be 2 and Jill will be 4. We can use the same ratio to find Jack's share:

2/6 x £60 = £20

So Jack receives £20.

(c) Let x be the age of Jack when he receives £25 from Uncle Fred. We know that:

1/4 x £60 = £25

Multiplying both sides by 4/60, we get:

x = 5/4

So Jack will be 5/4 years old, which is equivalent to 1 year and 3 months, when he receives £25 from Uncle Fred.

For an investment of 26,245, a quarterly statement reports that the account is 26,292. The statement reports that for the same quarter, the rate of return of the investment was - 0.02%. Given the information regarding the investment quarterly activity, does the reported rate of return seem reasonable?

Answers

No. The reported return rate appears lower than expected.

Rate of returns

To determine whether the reported rate of return is reasonable or not, we can calculate the expected rate of return based on the investment amount and the ending value of the account.

First, we need to calculate the total number of quarters that have elapsed between the initial investment and the current quarter. Let's assume that the investment has been held for n quarters.

Then, we can use the following formula to calculate the expected rate of return:

Expected rate of return = (Ending value / Initial investment) ^ (1/n) - 1

Plugging in the given values, we get:

n = 1 (since we are only given information for a single quarter)

Initial investment = 26,245

Ending value = 26,292

Expected rate of return = (26,292 / 26,245) ^ (1/1) - 1 = 0.18%

Comparing the expected rate of return of 0.18% with the reported rate of return of -0.02%, we can see that they are quite different. However, it's important to note that a single quarter's rate of return may not be indicative of the overall performance of the investment.

Therefore, while the reported rate of return seems lower than expected, we would need to consider the performance over a longer period of time to make a more informed assessment of the investment's performance.

A group of scientists is conducting an experiment on the effects of media on children. They randomly select 100 children and randomly assign each child to one of four treatment groups. Each treatment group has a specific amount of screen time during a one-week time frame. The first group has no screen time, the second group has two hours of screen time, the third group has four hours of screen time, and the fourth group has six hours of screen time. After the first week, the scientists conduct the same experiment, with the same subject groups, for three more weeks so that each group experiences each of the four treatments. Which statements about this study are true?
1. This study uses blocking.
2. This study uses blinding.
3. This study uses a control group.
4. This study uses a repeated measures design.
5. This study uses random sampling.

Answers

This study uses blocking: True. The study randomly assigns each child to one of the four treatment groups, which helps to control for individual differences that could affect the results.

This study uses blinding: It is not mentioned in the scenario whether the study uses blinding or not in individual.

This study uses a control group: True. The first group, with no screen time, serves as the control group. By comparing the results of the other groups to the control group, the scientists can see the effects of different amounts of screen time.

This study uses a repeated measures design: True. Each subject experiences each of the four treatments, so the study design is repeated measures.

This study uses random sampling: True. The study randomly selects group of 100 children for the experiment.

A theatre contains 457 seats and the ticket prices for a recent play were ​$54 for adults and ​$17 for children. If the total proceeds were ​$14,984 for a​ sold-out matinee, how many of each type of ticket were​ sold?

Answers

Answer: 195 adult tickets and 262 children tickets

Step-by-step explanation:

     Let a be adult tickets and c be children tickets.

We know there are 457 seats.

     a + c = 457

We also know the cost of the tickets and how much money was made.

     $54a + $17c = $14,984

Now, we have a system of equations we can use to solve.

     a + c = 457

     $54a + $17c = $14,984

Lastly, we will graph this system, see attached. The point of intersection, or where the lines intersect, is our answer.

     195 adult tickets and 262 children tickets.

Answer:

Chidden tickets were 262 and adult tickets were 195 tickets

Step-by-step explanation:

Let x = the number of children tickets

Let y = the number of adult tickets.

x + y = 457

17x + 54y = 14984

Use substitution

x + y = 457 Solve for y

y = 457 -x  Substitute 457 -x for y in the equation 17x + 54y = 14984

17x + 54y = 14984

17x + 54(457 -x) = 14984  Solve for x  Distributer the 54

17x + 24678 - 54x = 14984  Combine like terms

-37x = -9694   Divide both sides by -37

x = 262

The number of children tickets.

x + y = 457  Substitute 262 for x and solve for y

262 + y = 457  Subtract 262 from both sides

y = 195

The number of adult tickets.

You want to place stone pavers around the edges of your concrete patio. The patio is 12ft wide by 14ft long and each stone paver is 14 inches long. How many stone pavers will you need to go around the patio ( not counting the side against the house which is 14ft long)? Round to the nearest whole number

Answers

You will need 38/1.17 ≈ 32.48 stone pavers to go around the patio. Rounding to the nearest whole number, you will need 32 stone pavers.

Explain whole numbers

Whole numbers are a set of numbers that includes all natural numbers (positive integers) and zero. They are represented by the symbol "W" and do not include any fractions or decimals. Whole numbers are used in counting, measuring, and representing quantities of discrete objects or entities, and are a fundamental concept in mathematics.

According to the given information

First, let’s convert the length of the stone paver from inches to feet: 14 inches = 14/12 feet = 1.17 feet.

The perimeter of the patio is (12 + 14 + 12) feet = 38 feet. Since each stone paver is 1.17 feet long, you will need 38/1.17 ≈ 32.48 stone pavers to go around the patio. Rounding to the nearest whole number, you will need 32 stone pavers.
