Old mcdonald purchased a pool with a capacity 100 gallons for his farm. one day, at 1: 00 p. m., he placed a hose onto the pool which filled it with water at a rate of 5 gal per hour. after 10 hours, horses and cows started drinking the water at a rate of 2 gal/hr. five hours after that, mr. mcdonald noticed the animals and placed a second hose in the pool which filled it at a rate of 4 gal/hr. at what time and (am / pm) did mr. mcdonald have himself a pool full of water?

10 hours : 10*5 = 50 gallons

15 hours: amount in pool + hose * 5 hours - drinking*5 hours

      = 50 +5*5 - 2*5 = 50+25-10  = 65 gallons

100 = amount in pool + 1st hose*hrs - drinking*hrs + 2nd hose*hrs

hrs is after the 15 hours already filling the pool

100 = 65 gallons + 5*h -2h +4h

combine like terms

100 =65 +7h

subtract 65

35 = 7h

divide by 7

h=5

add the 15 hours before

20 hours to fill the pool

1pm + 20 hrs

24 hrs would be 1pm again so subtract 4 hours

9 am the next day

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
