Answer:

Area of circle, A = 616 cm^2

Step-by-step explanation:

Area of circle:

A = πr^2

Given: d = 28 cm and π = 22/7

so r = d/2 = 28/2 = 14 cm

So

A = π r^2

A = 22/7 * 14^2

A = 22/7 * 196

A = 616 cm^2

Diameter is= 28cm

Radius equals to 14

Area equals to πr*2

So 14*2=196

196π equals to 615.75

The unit rate in this problem is one payment per month. Since Martha has made 86 payments, that means it has been 86 months. Because of that, we can simply multiply 3335*86 to get 286810.

So she so far has paid $286,810 for her house payment

A circus ticket costs $7. On weekdays, the circus sells tickets at a 15% discount. What is the amount of the discount? How much
Airida [17]
Take the original price and multiply it by the percentage (not in percentage form) and divide it by 100

(7*15)/100=1.05

<u>$1.05 is the discount
</u>

7-1.05=5.95

<u>$5.95 is the ticket cost on a weekday</u>

Which ordered pair is the solution set for the system of equations below? 2x + y = 18 x – y = –6
qaws [65]

Answer:

(4,10) is the solution

Step-by-step explanation:

2x + y = 18

x – y = –6

Using elimination

2x + y = 18

x – y = –6

----------------------

3x    = 12

Dividing each side by 3

3x/3 = 12/3

x =4

Now we can find y

2x+y = 18

2(4) +y =18

8+y = 18

Subtracting 8 from each side

8-8+y = 18-8

y=10

(4,10) is the solution
