A store sells 6 T-shirts for $59.58. What is the unit cost per T-shirt?
Answer:
$10.00
Step-by-step explanation:
there are 6 tshirts sold and the total cost is 59.98 dollars, so you would divide 59.98 divided by 6. you would probably round because the answer would be 9.996667, rounding up would be 10.00. hope this helps a bit

What are Algebraic Identities?Algebraic identities are equations in which the right-hand side of the equation's value is exactly equal to the left-hand side of the equation's value. Any value for the variables satisfies them. To further comprehend this, let's look at an illustration.
(a + b)² = a² + 2ab + b²(a - b)² = a² - 2ab + b²(a + b)(a - b) = a² - b²(x + a)(x + b) = x² + x(a + b) + abgiven:
11a²– 15b²
Using the identity
(a² - b²)= ( a+ b)(a- b)
so, 11a²– 15b²
[(√11a)²– (√15b)²]
= (√11a - √15b) (√11a + √15b)
Hence, the difference can be displayed as (√11a - √15b) (√11a + √15b).

A) 6 · 5
B) 25 · 5 · 5 · 5
C) 125 · 125
D) 36 · 6 · 6 · 6
Answer:
C) 125 • 125
Step-by-step explanation:
5^6 is equivalent to 5 x 5 x 5 x 5 x 5 x 5
Three sets of five multiplied by one another is the same as 5^3 x 5^3 or 125 x 125.

PLZ HELP WITH NUMBER 4 AND 5
Answer:
Question 4: 70 degrees
Question 5: 150 degrees
Step-by-step explanation:
Question 4:
The shape is a polygon therefore we need to first find the sum of the angle. The formula is: (number of sides - 2) * 180
Rewrite: (5 - 2) * 180 = 540
To get the answer we add all angles together which is:
135 + 120 + 80 + 135 = 470
Minus to get the last angle:
540 - 470 = 70 degrees
So the answer is 70 degrees:
x = 70 degrees
Question 5:
Again the type of shape is an polygon so first we need to find the sum of the angle.
(6 - 2) * 180 = 720
Next add up all the angles together. The square boxes mean the angle is a right angle. So we can just add 90 degrees for every box you see.
90 + 90 + 120 + 120 = 420
Minus the answer with the sum of the total angle to get the missing value:
720 - 420 = 300 degrees
Next since there are two x, and they are at the same position they are the same value so we can just divide and get the answer.
300 / 2 = 150 degrees
Therefore the answer for both x are 150 degrees:
x = 150 degrees.

at a rate of 54 miles per hour. The
equation d = 54t models his
distance, d, over time ,t, in hours. Complete the table of values and identify the independent and variables.
Independent input -Time “0,1,2,3,4”
Dependent output- distance
“0,__,180,__,216”
*Fill in the blank*
WRONG ANSWERS GET REPORTED!!!
Answers:
First Blank = 54Second Blank = 162=============================================
Explanation:
The first blank represents the distance that corresponds to t = 1 hour.
We'll replace t with 1 to get...
d = 54t
d = 54*1
d = 54
Therefore, 54 goes in the first blank. It means that Isaac traveled 54 miles after 1 hour.
------------------
We repeat these steps for t = 3
d = 54*t
d = 54*3
d = 162
This means he traveled 162 miles after 3 hours
So 162 goes in the second blank
-------------------
Side note: your teacher wrote 180 but s/he should have written 108 instead because 54*2 = 108

Step-by-step explanation:
To solve this equation, use PEMDAS:
P - Parentheses
E - Exponents
M/D - Multiplication/Division
A/S - Addition/Subtraction
PEMDAS is the method that is used for the order of operations. Multiplication and division are interchangeable, so when there are only those signs left, you solve from left to right. This also applies to addition and subtraction.
Equations must always be solved in the order of PEMDAS -- P, then E, then M/D, then A/S.
Now, to solve the equation:
100 - 2(12 + 13) First, solve what is in the parentheses (P).
100 - 2(25) Next, multiply 2 × 25 (M).
100 - 50 Finally, subtract 50 from 100 (S)
50
100 - 2(12 + 13) = 50
An inverted pyramid is being filled with water at a constant rate of 70 cubic
centimeters per second. The pyramid, at the top, has the shape of a square
with sides of length 6 cm, and the height is 13 cm.
Find the rate at which the water level is rising when the water level is 3 cm.
cm/sec
Rates of change are the change of a quantity over another.
The rate of change in height of the water level is 36.51 cm per second.
Let the length of the top square be s, and the height be h.
The volume of the pyramid is:
[tex]\mathbf{V = \frac{1}{3}s^2h}[/tex]
At time t, we have:
[tex]\mathbf{V = \frac{1}{3}s(t)^2h(t)}[/tex]
The relationship between the side length and height is:
[tex]\mathbf{s : h=6 : 13}[/tex]
Express as fractions
[tex]\mathbf{\frac{s }{ h}=\frac{6 }{ 13}}[/tex]
Make s the subject
[tex]\mathbf{s=\frac{6 }{ 13}h}[/tex]
So, we have:
[tex]\mathbf{V = \frac{1}{3}s^2(t)h(t)}[/tex]
[tex]\mathbf{V = \frac{1}{3} \times (\frac{6 }{ 13}h(t))^2 \times h(t)}[/tex]
[tex]\mathbf{V = \frac{1}{3} \times \frac{36}{ 169}h^2(t) \times h(t)}[/tex]
[tex]\mathbf{V = \frac{1}{3} \times \frac{36}{ 169}h^3(t)}[/tex]
Differentiate
[tex]\mathbf{V'(t) =3 \times \frac{1}{3} \times \frac{36}{ 169}h^2(t) \times h'(t)}[/tex]
[tex]\mathbf{V'(t) =\frac{36}{ 169}h^2(t) \times h'(t)}[/tex]
Make h'(t) the subject
[tex]\mathbf{h'(t) = \frac{169 \times V'(t)}{36 \times h^2(t)}}[/tex]
The water level rises constantly at 70 cm^3/s, and the water level is 3 cm.
So, we have:
[tex]\mathbf{V'(t) = 70}[/tex]
[tex]\mathbf{h(t) = 3}[/tex]
[tex]\mathbf{h'(t) = \frac{169 \times V'(t)}{36 \times h^2(t)}}[/tex] becomes
[tex]\mathbf{h'(t) = \frac{169 \times 70}{36 \times 3^2}}[/tex]
[tex]\mathbf{h'(t) = \frac{169 \times 70}{36 \times 9}}[/tex]
[tex]\mathbf{h'(t) = 36.51}[/tex]
Hence, the rate of change in height of the water level is 36.51 cm per second.

What is the median for the data shown below?
S= [110, 105, 126, 65, 134, 102, 78, 80, 119, 67, 88]
Answer:
102
Step-by-step explanation:
The median of a data set is found by putting the data set in ascending numerical order and identifying the middle number. If there are an odd number of data values in the data set, the median is a single number. If there are an even number of data values in the data set, the median is the average of the two middle numbers. Sorting the data set for the values entered above we have:
65 , 67 , 78 , 80 , 88 , 102 , 105 , 110 ,119 , 126 , 134
Since there is an odd number of data values in this data set, there is only one middle number. With 11 data values, the middle number is the data value at position 6. Therefore, the median is 102.
Answer:
102
Step-by-step explanation:
1. The median is the quantity that's in the middle of a data set.
2. First, we have to arrange the given data set from least to greatest:
65, 67, 78, 80, 88, 102, 105, 110, 119, 126, 1343. Now, when we try and locate the middle number, we can see that the number is 102.
Therefore, the median is 102.
