Answer:
b
Step-by-step explanation:
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
Answer:
There is<em> no solution</em> to this problem.
Step-by-step explanation:
In order to find the solution, y or x needs to be shown.
The only correct answer would be A because of the following reasons
1. Sin is defined as opposite/hypotenuse
2. Cos is defined as adjacent/hypotenuse
