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:
m:-7.1 or greater
Step-by-step explanation:
Given function:
negative+negative=positive...
<u><em>Find what is greater than 70 would be the correct match for m:</em></u>
- -10·-8=80
- -10·-9=90
- -10·-10=100
Answer:Factor the polynomial
3(a−4b)2
Answer:
It is proportional because is it decreases 2 degrees ever half hour we know it would decrease 4 degrees every hour so the unit rate would be 4
Step-by-step explanation:
60/4=15=Dur8ng the time of 15 hours 60 degrees would have been decreased
