Phil can paint the garage in 12 hours and rick can o it in 10 hours. if they work together for 3 hours and then phil leaves, how long will it take rick to finish the job?

It will take 4.5 hours for rick to complete the job.

Step-by-step explanation:

Given:

Time taken by Phil to paint the garage = 12 hours.

It means that for each hour he does =  of the job.

.

Time taken by Rick to paint the garage = 10 hours.

It means that for each hour he does = of the job

.

If they work together for 3 hours,

Phil does job in 3 hrs =  

Rick does job in 3 hrs =  

.

So in three hours of working together job done =

.

This means job of the painting entire garage have been done 0.55 of it.

1 - 0.55 = 0.45.

So  there is 0.45 job left

At this point Phil quits and Rick presses on by himself. Since he does 1/10 of the garage every hour

Let T represents the time that Rick needs to complete the job after Phil leaves.

Hence,

Hence it will take rick 4.5 hours to complete the remaining job.

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

26?
