One data is missing. You need the volume of the pool or some data that permit you to calculate this volume.
The same statement given by you is part of a problem where you know a series of data that shows the time required to fill the pool at different flow rates:
flow rate time
60 gal/h 300 h => 60 gal/h * 300 h = 18,000 gal
45 gal/h 400 h => 45 gal/h * 400 h = 18,000 gal
36 gal/h 500 h => 36 gal/h * 500 h = 18,000 gal
30 gal/h 600 h => 30 gal/h * 600 h = 18,000 gal
So for, this pool to calculated (several times) that the volume is 18,000 gal.
Now you have two hoses one with a flow rate of 40 gal / h and the other with a flow rate of 60 gal/h.
The total flow rate is the sum of the two flow rates"
total flow rate = 40 gal/h + 60 gal/h = 100 gal/h
And you just must divide the volume of the pool (18,000 gal) by the total flow rate (100 gal/h) to get the time to fill the pool:
time = volume / flow rate = 18,000 gal / 100 gal/h = 180 h.
Answer: 180h
The answer is 21...3x^2=12 -2×=4 and add 5
Wouldn’t it be -10° since 0-15=-15° and +5, -10°
Answer:
less than 10 = 37.5 % green = 25%
Step-by-step explanation:
Percemt means parts out of 100
75%=75/100=15/20=3/4
turned in 6
if she turned in 3/4 of total assignments due then how many total?
6=3/4 times total
multily both sides by 4/3 to clear fraction
24/3=total
8=total
answer is 8 homeworks were assigned
