Answer:
inches per week
Step-by-step explanation:
This is a very simple ratio problem. Basically,
<em>If 
inches in 
week, then HOW MANY INCHES (let it be x) in 1 week???</em>
<em />
We set up two ratios and cross multiply and solve for x:
So average rate at which the water level changed every week is 5/6 inches per week.
Answer:
27
Step-by-step explanation:
Line x is the mid point of both lines
so the triangle becomes base = 19.2/2 = 9.6
hypotenuse = 24/2 = 12
using Pythagorean theorem:
x^2 = 12^2 - 9.6^
x^2 = 144 - 92.16
x^2 = 51.84
x = sqrt(51.84) = 7.2
The answer is 48 because you multiple four and 12 because they used twice the amount
