An above ground swimming pool is leaking. after half an hour the pool has leaked 7/8 of a gallon of water. how many gallons of water does a pool leak per hour. btw it is supposed to be a ratio

  7/4 gallon per hour

Step-by-step explanation:

If the leak rate is a constant, in twice the time, twice the amount of water will have leaked.

  2 × 1/2 hour = 1 hour

  2 × 7/8 gallon = 7/4 gallon

So, the leak rate is 7/4 gallon per hour.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
