Answer:
3.6 hours or 3 hours and 36 minutes.
Step-by-step explanation:
If the first pipe can fill the pool in 9 hours that means that in 1 hour it fills 
of the pool, we use the same logic for the second pipe and conclude that in 1 hour it feels up 
of the pool. If both were to fill the pool together that means that in 1 hour they would fill...
of the pool in 1 hour.

hours
3.6 hours in other words is 3 hours and 36 minutes.
Answer:
1,875 cm³
Step-by-step explanation:
first find the volume of the large rectangular prism, which is 2,000 cm³
Then find the volume of the small rectangle, which is 125 cm³
now subtract 125 from 2,000
which equals = 1,875
P = 3r + 2s --> P - 3r = 3r - 3r + 2s
2s = P - 3r --> 2s/2 = (P - 3r)/2
s = (P - 3r)/2
