To find average monthly income, multiply the net pay by the number of pay periods per year. Then divide this yearly income by 12 months.true
false

Answers

True. To find average monthly income, multiply the net pay by the number of pay periods per year. Then, divide this yearly income by 12 months.

For example:
Daily wages:
Daily wages * 365 days = Total Wage
Total wage / 12 months = average monthly income

Weekly wages:
Weekly wages * 52 weeks = total wage
total wage / 12 months = average monthly income

Answers

Step 1: Subtract 5 from both sides.
−8w+5−5=−43−5
-8w=-48

Step 2: Divide both sides by -8.
-8w/-8 = -48/-8

–3(t − 17) = 6 whats the answer

Answers

Answer:

t = 15

–3(t − 17) = 6

Step-by-step explanation:

1. Distribute the –3 to the terms inside the parentheses:

–3 * t + 3 * 17 = 6

2. Simplify:

–3t + 51 = 6

3. Next, we want to isolate the variable t by getting rid of the constant term. To do this, we can subtract 51 from both sides of the equation:

–3t + 51 - 51 = 6 - 51

This simplifies to:

–3t = -45

4. Now, to solve for t, we need to isolate the variable. Since –3t means –3 times t, we can divide both sides of the equation by –3:

–3t / –3 = -45 / –3

This simplifies to:

t = 15

So, the solution to the equation –3(t − 17) = 6 is t = 15.

The area of the parallelogram is 56 square miles. Find its base and height.height= x-5
base= x+5

Answers

The height of the parallelogram is 4 miles and the base is 14 miles.

What is the area of a parallelogram?

The area of a parallelogram is the product of the base and the height of the figure.

The area of a parallelogram = Base x Height

We have been given that the height is x-5, the base is x+5, and the area of the figure is 56 square miles.

So,

The area of a parallelogram = Base x Height

56=(x-5)(x+5)

Now Multiply x-5 and x+5

56=x²-25

Then Add 25 to both sides

81=x²

Now Take the square root of both sides

x=9

Now We can substitute it into the height and base thus,

Height: 9-5

Base=9+5

Therefore, the height of the parallelogram is 4 miles and the base is 14 miles.

The area of a parallelogram is A=bh. We are given that the height is x-5, the base is x+5 and that the area of the figure is 56 square miles. So,

56=(x-5)(x+5)
Multiply x-5 and x+5
56=x²-25
Add 25 to both sides
81=x²
Take the square root of both sides
x=9

With the value of x, we can substitute it into the height and base so,

Height:9-5
Base=9+5

So, the height is 4miles and the base is 14 miles.
We can check the answer by using the formula of the area of a parallelogram.
A=bh
56=4*14
56=56

Yvette is trying to calculate the distance between point C(1, 2) and point D(7, 10). Which of the following expressions will she use? square root of the quantity of 10 minus 2 all squared plus 7 minus 1 all squared square root of the quantity of 10 minus 1 all squared plus 7 minus 2 all squared square root of the quantity of 10 minus 7 all squared plus 2 minus 1 all squared square root of the quantity of 7 minus 10 all squared plus 1 minus 2 all squared

Answers

So this can be solve using the distance formula: D = sqrt [ (x2 – x1)^2 + (y2 – y1)^2] So the expression she should use is: D = sqrt [ (7 – 1)^2 + (10 – 2)^2] Then the answer would be: D = sqrt [ (6)^2 + (8)^2] D = 10

Answer:

square root of the quantity of 10 minus 2 all squared plus 7 minus 1 all squared
