Answer: 
Step-by-step explanation:
Given
Length L=15 feet
width b=2 feet
Volume V=375 cubic feet
Suppose h is the height
Volume is given by 

Since the ratio of sides is 4 to 3, the proportion is:

x =
9
Answer:
b. 0.86, 0.87
Step-by-step explanation:
a. Find attached solution to a
The answer is some number between 9 and 10.
Explanation:
√83
is an irrational number. You won't be able to simplify it any further either, since it doesn't have any perfect square factors.
However, you will be able to tell between which two numbers it lies in.
9^2 is 81 and 10^2 is 100
. Therefore, you can say that a certain number between 9 and 10 is 83 when squared.
If you're looking for an exact answer, then it will be 9.11043357914... (I got that using a calculator).
Answer:
x = 
Step-by-step explanation:
Given
x - 5 = 
Multiply through by 8 ( the LCM of 4 and 8 ) to clear the fractions
6x - 40 = 3 ( add 40 to both sides )
6x = 43 ( divide both sides by 6 )
x =
