Determine the time needed to deliver 72 papers at rate of 9 papers in 18 minutes.

Answers

Answer: The required time needed to deliver 72 papers is 2 hours 24 minutes.

Step-by-step explanation: Given that 9 papers are delivered in 18 minutes.

We are to determine the time needed to deliver 72 papers.

We will be using the UNITARY method to solve the problem.

We have

Time needed to deliver 9 papers = 18 minutes.

So, time needed to deliver 1 minute will be

$(18)/(9)=2~\textup{minutes}.$

Therefore, time needed to deliver 72 papers is given by

$2*72=144~\textup{minutes}=(120)/(60)~\textup{hours},24~\textup{minutes}=2~\textup{hours}~24~\textup{minutes}.$

Thus, the required time needed to deliver 72 papers is 2 hours 24 minutes.

So you need to find out time. What you do is divide 72 by 9 to get 8. Once you get 8, you have to multiply it by 18. Your answer is then 144 Papers

Which expression represents the cost of the mulch based on the radius of the circle?

Answers

we have

$m(x)=\pi x^(2)-2√(2)x^(2)$ ---------> equation 1

$g(m)=1.50m$ ---------> equation 2

To represent the cost of the mulch based on the radius of the circle

Substitute equation 1 in equation 2

$g(x)=1.50*[\pi x^(2)-2√(2)x^(2)]$

therefore

the answer is the first option

$1.50*[\pi x^(2)-2√(2)x^(2)]$

A recycle machine crushes 175 pounds of cans in 5 minutes. How many pounds of cans will the machine crush in 16 minutes?A) 560
B) 955
C) 1,925
D) 2,805

Answers

x = pounds of cans crushed

*use similar ratios

(175 lbs)/(5 min) = (x)/(16 min)

*find x by multiplying both sides by 16

x = (175 lbs)/(5 min)*(16 min) = 560 lbs

so . . . the answer is . . . A) 560

The answer will be A) 560 because when you divide 175 by 5 is with be 35 then multiply 35 by 16 that will give you 560. Your welcome :)
