Step-by-step explanation:
845/1160 = 0.728
116.5/174 = 0.669
42.25/58 = 0.728
23.4/29 = 0.806
16.9/23.2 = 0.728
25.35/34.8 = 0.728
Hence the 2nd, 4th and 5th options are correct.

<span>2. A pool company is trying out several new drains. Drain A empties a pool at a rate of 2 gal/min. Drain B empties a pool at a rate of 5 gal/min. One pool has 108 gal of water in it. Write an equation for each drain that shows the amount of time it takes to empty the pool. Then solve each equation showing your work.</span>
Drain A: rate is 2 gal/min. We do not know which pool has 108 gallons of water in it. If it's Pool A, then the time required to empty Pool A is
108 gallons
------------------- = 54 minutes
2 gallons/min
If it's Pool B, then we can represent the amount of water in Pool B by b. Then the time required to empty Pool B is
b (gallons)
------------------ = (b/5) minutes
5 gallons/min
Pythagorean theorem.
a^2+b^2=c^2
This means that the square of the length of the 2 legs of a right triangle added together = the square of the length of the hypotenuses or diagonal.
If you know 2 of the values in the 3 variables a,b,c what would you do to find the missing variable value?
I will not write the exact answers to this problem. I think you can figure how to write it out yourselves.
