Step-by-step explanation:
706.5 cubic feet of water should be put in the pool.
Step-by-step explanation:
Given,
The circumference of swimming pool = 157 feet.
The depth of the pool = 6 feet.
For safety purpose 
th of its height water is there.
To find the amount of the water should be there.
Formula
The volume of the pool = circumference×height
Now,
The height(h) of the water is = 6× ft = 
ft
So, the volume of the pool = 157× cubic feet
= 
cubic feet = 706.5 cubic feet.
Hence,
706.5 cubic feet of water should be put in the pool.
Answer: Kim took 50 minutes to read the third book.
Step-by-step explanation: If you substract 120 - 15 = 105. Then divide 105 / 3 = 35. And finally add 35 + 15 = 50.

3
Step-by-step explanation:
Answer:
PR = 15
Step-by-step explanation:
PR = PQ + QR
10x - 45 = 3 + x + 6 {Combine like terms}
10x - 45 = 9 + x {Subtract 'x' from both sides}
10x - x - 45 = 9
9x - 45 = 9 {Add 45 to both sides}
9x = 9 +45
9x = 54
x = 54/9
x = 6
PR = 10x - 45
= 10*6 - 45
= 60 - 45
PR = 15
