Answer:

<h3>1.57</h3>

Step-by-step explanation:

The formula for the area of a semicircle is

<h3>π (pi) * r^2 /2</h3>

The Diameter of your semicircle is 2, and the radius is half of the diameter, so the radius (r) of the semicircle is 1.

<h3>3.14 * 1^2 /2</h3>

Solve 1^2

<h3>3.14 * 1 / 2</h3>

According to PEMDAS, you solve the Multiplication first.

<h3>3.14 * 1 = 3.14</h3>

Now divide with your dividend above.

<h3>3.14 / 2 = 1.57</h3>

Therefore, your answer is 1.57

Received 50 = 15 + 50 = 65

New tires cost 75 = 65 - 75 = -10

Tracey:

PLEASE HELP I WILL GIVE BRAINLIST PLEASE
ivolga24 [154]

Answer: D: 4.5

Step-by-step explanation:

So the Equation I used for this would be

6(2x+3) = 3(6x-3)

In Which the left is the Hexagon (The 6 is for the 6 Sides) and the right of the equation is the triangle (given the 3 for the 3 sides. In order to solve, we need to solve for x. Distribute the equation and your left with

12x+18=18x-9

-12x            +9

27=6x

Divide to get X by itself

and your left with

4.5 = x

Hope it helped.

Adisa borrows $5,000 at 14% interest, compounded twice a year. How much does she owe at the end of 8 years?
N76 [4]

The borrower owes $14,760.82  at the end of 8 years

What is compounding interest?

Compounding interest means that earlier interest would earn more interest in the future alongside the loan principal.

Note that in this case the loan continues to accumulate interest because there no repayments, in other words, the loan balance after 8 years, which comprises of the principal and interest for 8 years can be computed using the future value formula of a single cash flow(the single cash flow is the principal) as shown thus:

FV=PV*(1+r/n)^(n*t)

FV=loan balance after 8 years=unknown

PV=loan amount=$5,000

r=annual interest=14%

n=number of times in a year that interest is compounded=2(twice a year)

t=loan period=8 years

FV=$5000*(1+14%/2)^(2*8)

FV=$5000*(1.07)^16

FV=$5000*2.95216374856541

FV=loan balance after 8 years=$14,760.82
