Which of the following statements best describes the value of the expression 7x + 6 when x = 5? A. The result is a fraction. B.
Ksivusya [100]

Answer: B) The result is a prime number

==================================================

Explanation:

Replace x with 5. Then use PEMDAS to simplify.

7x+6

7*5+6

35+6

41

The expression 7x+6 is equal to 41 when x = 5.

The value 41 is prime because its factors are only 1 and 41.

Tell whether the angles are complementary or supplementary. Then find the value of x.
gladu [14]

Answer:

  • 7) x = 5
  • 8) x = 20

Step-by-step explanation:

Complementary angles form a right angle and supplementary angles form a straight angle.

<h3>#7</h3>

<u>Complementary:</u>

  • 65 + 5x = 90
  • 5x = 25
  • x = 5
<h3>#8</h3>

<u>Supplementary:</u>

  • 2x + 6x + 20 = 180
  • 8x = 160

The formula for the volume of a sphere is v=4/3r3 what is the formula solved for r?
Salsk061 [2.6K]

Answer:

(3 V/ 4 pi) ^(1/3) =  r

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

We want to solve for r

Multiply each side by 3/4

3/4 V = 4/3*3/4 pi r^3

3/4 V = pi r^3

Divide each side by pi

3/4 V/ pi = pi/pi r^3

3 V/ 4 pi =  r^3

Take the cube root of each side

(3 V/ 4 pi) ^(1/3) = ( r^3) ^1/3

(3 V/ 4 pi) ^(1/3) =  r

Suppose you decide to put $12,500 in an account earning 9% interest compounded quarterly. How much interest would you earn after
Vesnalui [34]

Step-by-step explanation:

you add 9% to a number by multiplying that number by 1.09.

because adding 9% gives us in the end 109% of the original amount.

anyway, the formula for quarterly compounded interest is

Cq = P [ (1+r)^(4*n) – 1 ]

P is the starting principal amount

r is the interest rate per quarter (= interest rate / 4)

n would be the number of years (= 1 in our case).

so, the interest after 1 year is

12500((1 + 0.09/4)⁴ - 1) = 12500(1.0225⁴ - 1) =

= 12500 × 0.093083319 = $1,163.541485 ≈ $1,163.54
