Find the rate of change from 2012 to 2016

A. -10.5 students per year
B. 10.5 students per year
C. -11.25 students per year
D. 11.25 students per year

Answers

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

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.

The answer is 98 degrees for y

Answer:

Step-by-step explanation:

First, you should find the angle x because it will help in solving the angle y. A straight line adds up to 180 degrees, therefore x+y = 180

For the triangle on the left, sum up the angles and set it to 180 degrees.

60 + 38 + x = 180

x = 82 degrees

Now solve for y by doing this

82 + y = 180

y = 98 degrees

While I'm here, Ill solve for z because it will most likely ask in the next question.

26 + 98 + z = 180

z = 56 degrees

Step-by-step explanation: 18.3 because 5.8 + 4.5 =10.3 then add 8 its 18.3

Answer:

Step-by-step explanation:

We would first add up all of the hours, so that would be 5.8+4.5+8 to get 18.3 hours. Since it is saying $17.25 per hour we would multiply 17.25 and 18.3 to get 315.675. But, because we are dealing with money, our answer would be rounded to the nearest hundredth. So, Mathew earned $315.68 on Friday, Saturday, and Sunday altogether.

g÷ 5/8 =1
basically its asking what divided by 5/8 = 1

Answers

Answer:

5/8 divided by 5/8 = 1

Step-by-step explanation:

First, you know that dividing by a fraction is the same as multiplying by its reciprocal, so dividing by 5/8 is the same as multiplying by 8/5.

[tex]g / 5/8 = 1\\g * 8/5 = 1[/tex]

Now, multiply both sides by 5 to get rid of the fraction.

[tex]8g = 5[/tex]

divide both sides by 8

[tex]g = 5/8[/tex]

It’s asking you to what 5/8= 1 to do basically you have to multiply the 8 to both sides and then you probably will get your answer but I’m not to sure
