If q is the smallest composite number greater than 2 and p is the smallest prime number less than 10, what is p/q? a. 2 b. 0.5 c
Mrac [35]

Answer:

b. 0.5

Step-by-step explanation:

knowing that a prime number is an integer with exactly two divisors and a composite number is an integer with more than two divisors, we have that if q is a composite number greater than 2 these can be 4, 6, 8, .. But how the smallest of them should be is 4, and  p is a prime number can be 2,3,5,7,....

but  is the smallest prime number less than 10 then p=2, also p/q=2/4 = 0.5

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
daser333 [38]

Answer:

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 =  \frac{1}{12}of the job.

.

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

It means that for each hour he does = \frac{1}{10} of the job

.

If they work together for 3 hours,

Phil does job in 3 hrs =  3\times\frac{1}{12} = \frac{1}{4}=0.25

Rick does job in 3 hrs =  3\times\frac{1}{10} = \frac{3}{10}=0.3

.

So in three hours of working together job done = 0.3+0.25 = 0.55

.

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, \frac{1}{10}\times T= 0.45\\\\T = 0.45 \times 10\\T =4.5 hrs

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