Answer 1

Answer:

D. 11.25 students per year

Step-by-step explanation:

rate of change

[tex] = \frac{400 - 355}{2016 - 2012} [/tex]

[tex] = \frac{45}{4} [/tex]

=11.25

Answer 2

The rate of change from 2012 to 2016 is 11.25 students per year.

Therefore, the correct answer is D.

Given that a graph is showing the number of students in a class.

We need to find the rate of change from 2012 to 2016.

Also, from the graph we can see the number of students in 2012 and 2016 was 355 and 400 respectively.

To find the rate of change from 2012 to 2016, we can use the formula:

Rate of change = (Final value - Initial value) / Time interval

In this case, the initial value is the number of students in 2012, which is 355, and the final value is the number of students in 2016, which is 400.

The time interval is 4 years (from 2012 to 2016).

Plugging these values into the formula, we get:

Rate of change = (400 - 355) / 4

= 45 / 4

= 11.25

Therefore, 11.25 students have changed between 2012 and 2016 with this rate of change.

Regina travels ½ of a kilometer for every ¼ of a minute she drives. You were told that the trip from Times Square to Pelham Parkway is 72 kilometers. How many minutes would her trip have taken by car?

Answers

Answer:

36 minutes.

Step-by-step explanation:

The best way to solve this is to find how much distance is traveled in a minute and then divide the total distance by the distance traveled in a minute. Now let's apply.

1/4 x 4 = 1 minute, so in this problem, 1/2 x 4 = 1 minute.

1/2 x 4 = 2.

72 / 2 = 36.

Her trip would have taken 36 minutes by car.

Answer:

36 minutes.

Step-by-step explanation:

For every mile she takes it's 1/2 of a minute. Then just do 72/2 and get 36 :)

Step-by-step explanation:

Step 1: Add 1.5 to both sides

-1.5x + 6 + 1.5x = 8 + 1.5x

6y = 1.5x + 8

Step 2: Divide both sides by 6

6y/6 = 1.5x + 8/6

Y = 0.25x + 4/3
