Answer:
A
Step-by-step explanation:
Lets say, for ease, that the vat can hold a total of 70 gallons (or whatever you would like to use.) Use whatever number you want, I just picked this because it gives us a lot of clean numbers.
Now, if the inlet can fill it in 7 hours, that means that it is adding 10 gallons per hour. (70 gal/7 hours = 10 gal/hr)
For the outlet, use the same process, and you find that it drains the vat at 7 gallons per hour.
So, if you subtract the outlet from the inlet, you get 10 - 7 = 3 gallons per hour added.
Now just divide the size of the vat by that number, and you find your answer.
70 gallons / 3 gallons per hour = 23 1/3 hours.
Answer:
13 2/3 yds
Step-by-step explanation:
We know that there are 3 ft in 1 yd
41 ft * 1 yd / 3ft = 41 / 3 yds
Changing to a mixed fraction
39/3 + 2/3 yds
13 + 2/3 yds
13 2/3 yds
Answer:
the area will be zero and hence they lie on same line
