the formula of the volume of pyramid = 1/3*h*base
the volume of prism= base*h
we know that the height of the pyramid is three times more than the height of prism so that if the height of the prism is a - the volume of a prism is a*base
the height of the prism is 3a so that the volume of the pyramid is 1/3*3a*base=a*base
the Answer of the ratio is 1/1
I hope that helps, and I hope that makes sense
Given:
The area of a square picture frame is 55 square inches.
To find:
The length of one side of the frame.
Solution:
Let the length of one side of the frame is x inches.
Area of square is
where a is side length.
Area of frame is
Taking square root on both sides.
, so . Since 55 is closer to 49, therefore, is closer to 7.
Therefore, the length of one side of the frame is 7 inches.
XY = -4
Answer:
The student added instead of subtracting 6 from both sides first before dividing.
5•1=5
Answer:
Multiplication identity
Step-by-step explanation:
We are given that
We have to find which property of real number is used in given expression.
Multiplication identity: It is defined as the number by which multiply any number and get itself.
Then, 1 is multiplication identity.
When we are multiplying 5 with 1 then we get 5.
Therefore, 1 is multiplication identity.
Hence, multiplication property of real numbers is used in given expression.
B. 1
C. 2
D. an infinite number
