This question has four parts. 32 Colton is heating a pot of water. He records the temperature of the water in
the pot every minute. This equation models Colton's data, where x represents
the number of minutes the water has been heated, and y represents the
temperature of the water in degrees Fahrenheit.
y = 7.5x + 40
What is the temperature in degrees Fahrenheit of colton's pot of water after 16 minutes. Hi Ayer boils at a temperature of 212 after 16 minutes of heating how much additional time to the nearest minute will be needed for the water to boil.

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.

it would take 7/10 of an hour too fill the pool.

if i put something wrong your not gonna like it so rather not say nothing.
