The sand makes up a rectangular prism of dimensions 8' by 10' by 0.5'.
The volume of sand is then V = L*W*H, or V = (10')(8')(0.5') = 40 cubic ft.
The Solution.
The given equation is

Substituting 11 for x, we can get the value of y.

Hence, the value of y is 18.
Answer: arithmetic
Step-by-step explanation:
arithmetic is if it is added or subtracted by a common number while geometric is multiplied or divided by a common number.
Answer:
Percent change from 15 to 18.
You need to divide the numbers, but which one goes on top?
You know the number increases from 15 to 18, so the percentage must be greater than 100%.
The only way to get a number greater than 100% is to put the larger number on top.
Therefore, the answer is 18/15 = 1.2
Multiply by 100 to get a %
1.2 * 100 = 120%
2. Calculate percentage change
from V1 = 5 to V2 = 8
ans= 60%
overall answer gain of 15 yards and 18 yards
