Abaker baker 40 cookies in and hour . what is the repentant and independent variable

Step-by-step explanation:

If we write the description of the relationship between number of cookies (c) and time in hours (t) as ...

  c = 40t

then c is the dependent variable and t is the independent variable.

That's not the only way the relationship could be written. Which variable is which depends on how you define them and what you want to know. If you want to know the number of hours to bake "c" cookies, then "c" is the independent variable.

This sort of problem statement seems to assume that cookies are being produced continuously, not in batches. In order for any functional relation to properly express the scenario, the domain of the independent variable may need to be restricted to integer hours (or multiples of 40 cookies).

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.
