My brother thought of this question. Ya'll probably don't know, but my
brother Tucker has been doing the lessons and quizzes with you all. On the
Translating Translations quiz the average grade for the class was 65%. A
total of 20 students have taken the quiz (including my brother Tucker).
Tucker scored 100%. If we take his score out from the class, what is the
class average?

450 is the final answer! : )

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

the aswere is the one with all 8's and the second one is with the 10,8 and 6

step-by-step explanation:

i think the correct option is the second option.
