The amount of building material needed to cover the pyramid which Tony's architecture firm is constructing is 144 square feet.
What is area of triangle?The area of the triangle is half of the product of base and height of the triangle. It can be calculated as,
[tex]A=\dfrac{1}{2}b\times h[/tex]
Here, b is the length of base, and h is the height.
Tony's architecture firm is constructing a square pyramid play structure for a school.
The length of one side of the base will be 9 feet, Each face is a triangle with a height of 8 feet. The pyramid will be open at the bottom and not covered.As the height of the triangle is 8 and base is 9 feet of triangle. Thus, the area of one triangular face is,
[tex]A=\dfrac{1}{2}\times9\times8\\A=36\rm\; ft^2[/tex]
Area of 4 triangle side is,
[tex]A=36\times4\\A=144\rm\; ft^2[/tex]
Thus, the amount of building material needed to cover the pyramid which Tony's architecture firm is constructing is 144 square feet.

You know a calculator exists right?
An employee at a gift shop earns $72.00 for working 9 hours. At this hourly rate, what should the employee earn for a 40-hour work week?
A.$8.00
B.$48.00
C.$121.00
D.$320.00
At this hourly rate, the employee earns a 40-hour workweek is D.$320.00
In the above case, an employee earns $72.00 for working 9 hours a day or 9 hours, now to know about hourly earing we should divide $72.00 by 9 hours so that we can get the earnings of the employee on an hourly basis.
Therefore, earnings an hour = 72.00/9 = 8, which means the employee is earning 8 dollars for every hour he works at the gift shop, now to know how much money he/ she will generate in 40 hours we will multiply 8 dollars with 40 working hours.
Therefore total earnings of the week = earning per hour * total working hours = 8*40 = $320.00 for every 40-hour week. hence, the total earnings for the week will be $320,
Calculations
earning per hour =72.00/ 9 = 8
total earning = 40*8 = 320
correct option will be D. $320

Complete the following statement: The equation is (false, true) when x = 4, so 4 (is, is not) a solution.
Answer:
False, is not
Step-by-step explanation:
If we plug in 4 for x in the equation, we get that 5 * 4 + 3 = 12, and we can calculate that 20 + 3 = 12, which is not true. 4 is a false solution for that equation so it is not a solution (We can use this info to say that the answer is false, is not).

Find the area of a circle whose circumference is the same as the perimeter of a square of side 22 cm. (Take π = 22/7)
Answer:
Perimeter of a square=circumference of circle
4×22=2πr
44=πr
r=14
Area of circle=πr2
22/7×14×14
28×22
616
Answer:
176cm²
Step-by-step explanation:
Side of square = 22cm
Perimeter of square = 88cm
Circumference of circle = perimeter of square
2π r = 88cm
2 x 22/7 x r = 88cm
44/7 x r = 88cm
r = 88 x 7/44
r = 14cm
Area of circle = π x r x r
= 22/7 x 14 x 14
= 44 x 4
= 176 cm²

81 is 18% of what number?
Enter your answer in the box.
Answer:
450
Step-by-step explanation:
Formula = Number x 100
Percent = 81 x 100
18 = 450
Following shows the steps on how to derive this formula
Step 1: If 18% of a number is 81, then what is 100% of that number? Setup the equation.
81
18% = Y
100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
18Y = 81 x 100
18Y = 8100
Y = 8100
100 = 450
Answer:
450
Step-by-step explanation:
18% of 450 is 81. 100% of 450 is 450, therefore 18 percent of 450 equals 81. To learn how to solve 81 is 18 percent of what Number, see the step by step instructions below.

Answer:
A. The rectangular prism will have a perimeter of 32 centimeters along the base.
Step-by-step explanation:
When your looking for perimeter, you don't use the height, however, you have to take into account the half sized cubes, in order to get an accurate perimeter, you have to multiply everything by it's multiplicative inverse in order to fill everything with the cubes. Thus, the first option makes the most since you have to double the height and length, when you do so, you get 10 10 6 and 6. You then add them together to get 32.
I really hope this makes since and that I didn't get it wrong. Have a good day and Good luck!

5m + 8 and -2m - 6. Could i get the answer and an explanation?
Answer:
m=-5
Step-by-step explanation:
Simplifying
5m + -6 = 8m + 9
Reorder the terms:
-6 + 5m = 8m + 9
Reorder the terms:
-6 + 5m = 9 + 8m
Solving
-6 + 5m = 9 + 8m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-8m' to each side of the equation.
-6 + 5m + -8m = 9 + 8m + -8m
Combine like terms: 5m + -8m = -3m
-6 + -3m = 9 + 8m + -8m
Combine like terms: 8m + -8m = 0
-6 + -3m = 9 + 0
-6 + -3m = 9
Add '6' to each side of the equation.
-6 + 6 + -3m = 9 + 6
Combine like terms: -6 + 6 = 0
0 + -3m = 9 + 6
-3m = 9 + 6
Combine like terms: 9 + 6 = 15
-3m = 15
Divide each side by '-3'.
m = -5
Simplifying
m = -5
