Complete Question: 

Janet completed this entire column of math homework in 10 minutes. How many seconds per question did Janet spend?

BTW there is 8 questions in the row

Answer: 

Janet spent 75 seconds on each of 8 question

Step-by-step explanation:

We know, every 1 minute consists of 60 seconds. In question, given as 10 minutes. So, it can be expressed in seconds as below,

1 minute = 60 seconds

Hence 10 minutes = 10 (60) = 600 seconds

Let’s consider ‘x’, the time spent on every single question by her.

To find the time spent by Janet on each question, divide 600 seconds by the number of questions she did.

Divide 600 by the number of questions, generally the equation can be formed as ,

$\frac{600}{\text { number of questions }}= 'x' seconds per question$

If the number of question is ’8’, then

$'x' seconds per question =\frac{600}{8}=75 seconds$

Hence, Janet spent 75 seconds on each of 8 question

Using conversion of units and volume of a cylinder, it is found that 23.17 cubic yards of concrete are needed, option D.

The volume of a cylinder of radius r and height h is given by:

$V = \pi r^2h$

In this problem:

We want the volume in cubic yards, thus, the units of radius and height have to be in yards.
32 inches in diameter, thus 16 inches of radius. Since each inch has 0.0278 yards, this is a radius of 0.44 yards, thus $r = 0.44$ .
Height of 8 feet, and since each feet has 0.33 yards, this is a height of 2.67 yards, thus $h = 2.67$
14 poles, thus the volume is multiplied by 14.
