How long will it take to fill the pool if two hoses are used, one that fills at a rate of 40 gallons per hour and one that fills
jok3333 [9.3K]
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

Test the four possible vertices that you found in the objective function in part A. Use those values to determine which set of v
irga5000 [103]

The testing of the four vertices of the objective function gives;

C(5, 0, 55) = 430

C(5, 30, 25) = 400

C(15, 30, 15) = 420

C(45, 0, 15) = 510 (maximum)

<h3>How to test objective functions?</h3>

The objective function is seen as attached.

Now, it is noticed that just two of the vertices are listed. The other two vertices are intersections of x + y + z = 60 with x = 5 and the constraints on y.

We will assume that; 0 ≤ y ≤ 30

Thus, the missing vertices are;

(x, y, z) = (5, 0, 55)  and  (5, 30, 25)

The two given vertices are;

(x, y, z) = (15, 30, 15)  and  (45, 0, 15)

Therefore, the objective function values are;

C(5, 0, 55) = 9·5 +6·0 +7·55 = 45 +0 +385 = 430

C(5, 30, 25) = 9·5 +6·30 +7·25 = 45 +180 +175 = 400

C(15, 30, 15) = 9·15 +6·30 +7·15 = 135 +180 +105 = 420

C(45, 0, 15) = 9·45 +6·0 +7·15 = 405 +0 +105 = 510

A square piece of plastic has a perimeter of 8 cm. how long is each side of the piece of plastic?​
Aleksandr-060686 [28]

Answer:

Step-by-step explanation:

Since it is a square, all four sides are equal and its perimeter is just

P=4s, so if P=8 then

4s=8, dividing each side by 4 we get

s=2

So each side of the plastic square is 2 centimeters.
