Answer: 13.96 in²

Step-by-step explanation:

  • radius (r)

d = 2r

16 = 2r

8 = r

  • angle in radians (θ)

(180)/(\pi) =(25)/(\theta)

180(θ) = 25(π)

      θ  = (25)/(180)\pi

      θ  = (5)/(36)\pi

  • Area (A)

A = (1)/(2)r² θ

   = (1)/(2)(8)^(2)((5)/(36)\pi)

   = (40)/(9)\pi

   = 13.96

Answer: 270°, 630°, -450°, -810°

Step-by-step explanation:  

positive:  -90 + 360 = 270

                                    270 + 360 = 630

negative: -90 - 360 = -450

                                   -450 - 360 = -810

Answer: \frac{3\pi} {4}

Step-by-step explanation:  

  \frac{19\pi} {4} - 2\pi

= \frac{19\pi} {4} - \frac{8\pi} {4}

= \frac{11\pi} {4}

(11\pi)/(4) - 2\pi

= \frac{11\pi} {4} - \frac{8\pi} {4}

= \frac{3\pi} {4}

If you subtract another 2π, you will end up with a negative value.  The question asks for the smallest positive value.

Write the given sentence as an equation. Tim s age in 7 years will be three times what it was 19 years ago.

Answers

Hi,
Let's say x if the actual age of Tim.
In 7 years, he will be old of x+7
19 years ago, his age was x-19
So
x+7=3*(x-19)
==>3x-57=x+7
==>3x-x=7+57
==>2x=64
x=64/2
==>x=32

Proof:
age=32
in 7 years: 32+7=39
19 years ago 32-19=11
and 39=3*11

If x and y are integers, and 3x + 2y = 13, which of the following could be the value of y ?A. 0
B. 1
C. 2
D. 3
E. 4

Answers

They are all integers so...
first lets substitute
A.3x=13
X=13/3
b.3x+2=13
3x=11
x=11/3
c.3x+4=13
3x=9
x=3
d.3x+6=13
3x=7
x=7/3

E.3x+8=13
3x=5
x=5/3

therefore the possible is letter c because it must be an integer and the definition of integer states that it is not a decimal nor a fraction
C. 2
Because
3x+2(2)=13
3x+4=13
3x=9
x=3

None of the other solutions work out so that both x and y are integers.

Bob’s employer covers 23% of his family’s annual health insurance premium. The balance of the premium is deducted in equal amounts from Bob’s paycheck 26 times over the calendar year. If $185.30 is withheld from each of Bob’s paychecks, what is his family’s annual health insurance premium?

Answers

Since 23% of his family’sannual health insurance premium is covered by bob’s employer, so only 77% ofthe insurance bob’s needs to pay. So the total that bobs paid is equal to

$ 185.30 x 26 = $ 4,817.8. sothe total insurance is $ 4,817.8/0.77 =$ 6256.88

Bob’s family annual health insurance premium is $6,256.88

From the given question:

  • Each amount withheld from Bob’s paychecks = $185.30
  • Bob’s family annual health insurance premium =?
  • We are also given question that the balance of the premium is deducted in equal amount from Bob’s paycheck 26 times over the calendar year.

Further Explanation

Firstly, we have to determine bob’s salary by multiplying each amount withheld from Bob’s paycheck.  

Therefore we have:

26 x 185.30

= $4817.80

Recall that the Bob’s family annual health insurance premium covers by his employer = 23%, it then means bob will have to cover 77% of the health insurance.

Therefore, to calculate bob’s family annual health insurance premium, you have to divide bob’s salary by the amount pays by Bob, which is 77%

Therefore, you have:

4817.80 / 0.77 (77/100)

= $6,256.88

Therefore, Bob’s family annual health insurance premium is $6,256.88
