Matthew has lived in NY for 10 years. Matthew earns $17.25 per
hour. He worked 5.8 hours on Friday, 4.5 hours on Saturday, and 8
hours on Sunday. How much money did Matthew earn in all on Friday,
Saturday, and Sunday?

Answers

Answer:18.3

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

Answer:

$315.68

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.

2y - 15 = 25

2y - 15 + 15 = 25 + 15

2y = 40

2y ÷ 2 = 40 ÷ 2

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.

Answer:

A secant line contains a chord always

Step-by-step explanation:

A line intersecting in two points is called a secant line, in one point a tangent line and in no points an exterior line. A chord of a circle is the line segment that joins two distinct points of the circle. A chord is therefore contained in a unique secant line and each secant line determines a unique chord.

Hi I need help with this problem. But it has to be shown with work. Does anyone know?
x : 6 = 10 : 150

Answers

Answer:

its is 90

Step-by-step explanation:

6x10=60 150-60=90

Answer:

0.4 or 2/5???

Step-by-step explanation:

I believe this is a proportion/ratio problem.

Think of it like this:

x/6 = 10/150

To solve for x, you must cross multiply:

150x = 6*10 (150x... DON'T write 150*x, that is nonsense)

150x = 60

x = 60/150 (you divide because you are actually dividing 150 on both sides and doing the opposite operation of multiplication)

x = 6/15

x = 2/5 or 0.4 (I simplified it)

Hopefully this helped? I can't seem to find a whole number answer... so the only options I could do are 2/5 or 0.4

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
