Ill give brainless. Explain the relevance of the instructor's questions. Emil is nine years old. He likes singing and listening to music. His parents are considering enrolling him in an orchestra camp for 9-12 year old children. The instructor asks many questions to assess Emil's readiness. He is concerned when he hears Emil is still dog paddling after taking swimming lessons, but is glad to hear that Emil enjoys taking voice lessons and that he responds well when his teacher corrects his spelling. ​

The instructor is trying to help Emil approach questions in a better way, and he also corrects his spellings so he then later knows how to do the spelling. The questions help him to think, and the more questions the more answer, better answers.

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.
