Paige earned $15.50 per hour. She received an 18% raise. If Paige worked 10 hours at her new salary. How much did Paige earn?
BaLLatris [955]
First, figure out the new salary. To do this, multiply 15.50 and 0.18. This is 2.79. Add this to 15.50.

15.50 + 2.79=18.29

Therefore, $18.29 is her hourly pay.

To find how much money she earns in 10 hours, multiply this pay per hour (18.29) times the hours worked (10).

18.29 x 10

182.9

This means that Paige earns $182.90 for working 10 hours.

Hope this helps! Please comment if you need any more explanation and I’ll get back to you ASAP :)

Answer:

Other needs =25,2 degrees

insurance = 100,8 degrees

Taxes= 7,2

Housing = 57,6

food= 57,6

childcare = 64,8

transportation = 46,8

Step-by-step explanation:

Its % of 360 degrees so you have to calculate the percentage of each categorie on 360 degrees to find the angles. Exemple, for the Other needs, you take 7% out of 360 degrees and you find that it is equal to 25,2. (7% x360 degrees /100)

Point R divides in the ratio 1 : 3. If the x-coordinate of R is -1 and the x-coordinate of P is -3, what is the x-coordinate of
dimaraw [331]

Answer:

C. 5

Step-by-step explanation:

Point R divides the line segment PQ internally. The x-coordinate of the point which divides the line segment in ration m:n internally can be calculated as:

x=(\frac{mx_{2}+nx_{1}}{m+n} )

Here, x1 is the x-coordinate of 1st point, x2 is the x-coordinate of 2nd point, x is the x-coordinate of point dividing the segment. We have all the values except x2. Using the given values in above formula, we get:

-1=\frac{x_{2}+3(-3) }{1+3} \\ \\-4=x_{2}-9\\\\ 5=x_{2}

Thus the x-coordinate of point Q will be 5

The x-coordinate of Q is 5.

Please help, thank you
grandymaker [24]

Answer:

x = 20

Step-by-step explanation:

The angles that are marked are called "vertical angles" (I think of a pair of scissors) The two angles are equal to each other. (They get bigger or smaller together, like a pair of scissors)

So, set them equal to each other and solve.

3x + 50 = 6x - 10

SUBTRACT 3x from both sides.

50 = 3x - 10

ADD 10 to both sides.

60 = 3x

DIVIDE both sides by 3.

20 = x
