Answer:</h3>
Your selection is correct: 180 hours
<h3>
Step-by-step explanation:</h3>
The pool is apparently 18000 gallons (= 60 gal/h × 300 h). The combined flow from the two hoses is ...
... (40 gal/h) + (60 gal/h) = 100 gal/h
So, the time required with the two hoses is ...
... 18000 gal/(100 gal/h) = 180 h
The answer would be 1/3 of the population is children. All you need to do to solve this problem is divide the portion of the population (in this case, children) by the total of the population. Therefore, you have 1342/4026 which reduces to 1/3. If you would like to represent this as a percent, it would be approximately 33.33%
Volume of container = <span>π x 4^2 x 6/4 = 75.40 cubic units
volume of empty space = volume of box - volume of container = 96 - 75.40 = 20.60 cubic units
