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.

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, and each face is a triangle with a height of 8 feet. The pyramid will be open at the bottom and not
covered. What will be the amount of building material needed to cover the pyramid?
A: 144 square feet
B: 225 square feet
C: 288 square feet
D: 369 square feet
(no it doesn’t have an image)
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,

You can complete 1/6 of your task in an hour. Your friend can complete 1/6 as the same task in an hour how long will it take to complete a task if you work together?
If you and you friend both can complete 1/6 of a task alone, you have to add 1/6+1/6 to find how fast you can work together. That comes out as 2/6 or 1/3 if you reduce. so It will take 3 hours for you to complete a task because 1/3+1/3+1/3=1
