Answer:

A = 78.5 cm^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

We know r =5 and pi = 3.14

A = 3.14 (5^2)

A = 3.14 (25)

A = 78.5 cm^2

Write an equivalent expression for 25x - 45 using the properties of operations. Hint: find the GCF of 25 and 45. You use parenth
Oksana_A [137]

Answer:

25x - 45 = 5(5x - 9)

Step-by-step explanation:

Find the greatest common factor (GCF) of 25 and 45.

You can do this several ways, but one way is to list all the factors of both numbers and find the greatest common one:

Factors of 25: 1, 5, 25

Factors of 45: 1, 3, 5, 9, 15, 45

Therefore, 25 and 45 have 2 common factors: 1 and 5

So the greatest common factors is 5

25x - 45 = 5(ax - b)

To find the value of a, simply divide 25 by 5: 25 ÷ 5 = 5

To find the value of b, divide 45 by 5: 45 ÷ 5 = 9

25x - 45 = 5(5x - 9)

Ayana works at Eastern Community College as a math teacher. She will
AveGali [126]

Answer:

  a.  $2622.00

Step-by-step explanation:

After taking out federal health insurance taxes, Ayana's pay for the year will be ...

  $45000 × (1 - 0.224) = $45000 × 0.776 = $34,920

On a monthly basis, that is ...

  $34,920/12 months = $2910 per month

Then, additional deductions of $3 + 85 + 200 = $288 are made, so her pay will be ...

  $2910 -288 = $2622 per month

_____

<em>Comment on federal taxes</em>

Federal income taxes are not accounted for in the problem statement. If Ayana can claim "head of household" status (and is not married), she will have federal income tax on the order of $121 per month deducted from the above amount, assuming her retirement plan deduction is "before tax."

What is LP ? <br><br> A. 36<br> B. 40<br> C. 44<br> D. 48<br> E. 52
Sonbull [250]

Answer:

The correct answer is option D.  48

Step-by-step explanation:

From the figure we can see that, some right angled triangles.

<u>To find the measure of LP</u>

Consider the right angled  triangle LPT,

LT is the hypotenuse, LP = 50 units  (given)

PT = QT = RT = 14 units

From figure we get,

LP² + PT² = LT²²

LP² = LT² - PT²

 = 50² - 14²

 = 2500 - 196

 = 2304

LP =√2304

 = 48

The correct answer is option D.  48
