Answer:

Step-by-step explanation:

Perimeter = 20.56mm

Given the perimeter, find the diameter

= 20.56

D = 20.56 ÷

D = 6.54 mm

Perimeter of the Semicircle = half the circle arc + the straight line (Diameter)

Semicircle = 0.5(20.56) + 6.54cm

Semicircle = 16.83mm

Answer:

Distributive property

Step-by-step explanation:

Think of Distributive property being a party. the host is outside of the house (the parenthesis) and wants to greet everyone at the party. so 2x3k=6k and 2x5=10. so you replace 2(3k+5) with 6k+10

GarryVolchara [31]

Answer:

  $5599.20

Step-by-step explanation:

The quarterly interest rate for the first two years was ...

  7%/4 = 0.0175

So, the multiplier each quarter for those 8 quarters was 1+0.0175 = 1.0175. At the end of the first 8 quarters, the account value had been multiplied by ...

  1.0175^8

For the next 8 quarters, the quarterly interest rate was 10%/4 = 0.025. So at the end of those 8 quarters, the balance had been multiplied by ...

  1.025^8

Then the balance at the end of 4 years was ...

  $4000(1.0175^8)(1.025^8) ≈ $5599.20

The balance was $5599.20.

What is the value of x?
pantera1 [17]
Triangles= 180°

Add the 3 angles to equal 180°


17x + (10x - 5) + 50= 180
combine like terms

27x + 45= 180
subtract 45 from both sides

27x= 135
divide both sides by 27

x= 5


ANSWER: x= 5

Hope this helps! :)
