What is the rest of the question?
First, we need the volume of the room. We get this by multiplying the length, width, and height. This gives us 18,000 ft^3. Now, we see how many BTUs were created. We do this by multiplying 2,200 by 20. This gives us 44,000. Now, we divide 44,000 by 18,000 to get our answer, which is 2.44 BTUs/ft^3, or C.
0.35 cups/hour
To be able to determine the rate at which the water is leaking from the pipe with the information given, you have to divide the number of cups by the number of hours in which they were collected:
12 cups/34 hours= 0.35 cups/hour
According to this, the answer is that the rate at which the water is leaking from the pipe is 0.35 cups/hour.
Hope this helps!!
Since we know that Zack must pay $11.00 per $100 monthly, we just need to divide the total amount of the loan, $1,087, by $100 to check how many times he must pay $11.00 each month:

Now we know that he must pay $11.00 10.87 times each month, so the last thing we are going to do to find his monthly payment is multiply both quantities:

We can conclude that Zack's monthly payment is $119.57
