300ml in 5 min can be written as a fraction 300ml/5min or 300/5 ml per min. 300/5 is the same as 60/1
So 300ml / 5min = 60ml/1min
We are given the average body heat equal to 2200 BTU. In this problem, we are asked to determine the total body heat in BTU per cubic foot given the dimensions of the room. The volume of the room is 18000 ft3. we multiply the average heat by 20 persons.hence the answer to this problem is 2.44 BTU/ft3.
1/10*(f-220) or 0.1(f-220)
When we prime factorize, we get 180=2^2*3^2*5. So therefore there are 3 prime factors that make up 180.
