7. What I did is divide 520 by 8 to get the miles and hour. I got 65. Since you can get 65 miles and hour, i divided 455 by 65 to get 7.

Find the area of the shaded region in the figure below, if the radius of the outer circle is 4 and the radius of the inner circl
denis-greek [22]

TheThe  area of the shaded region  if the radius of the outer circle is 4 and the radius of the inner circle is 2 is 12π.

<h3>Area of the shaded region</h3>

Area of a circle = πr²

r =radius of the circle

Area of the outer circle:

Area of the outer circle = π(4)²

Area of the outer circle = 16π

Area of the inner circle:

Area of the inner circle = π (2)²

Area of the inner circle = 4 π

Area of the shaded Region :

Area of the shaded Region = 16π - 4 π

Area of the shaded Region = 12π

Therefore the  area of the shaded region  if the radius of the outer circle is 4 and the radius of the inner circle is 2 is 12π.

If you have a balance of 1,000 on your edit card and the interest rate is 17 3/4% a year in order to pay off the $100 in 5 years
ankoles [38]

Answer:

$2,263.63

Step-by-step explanation:

You start with "if" but don't end with what your goal is.  I will assume that you want to know how much you'll have to pay after 5 years to pay off this $1,000 loan.  

Use the compound amount formula A = P(1 + r)^5.  Replacing P with $1,000, r with 0.1775 and t with 5 years, we get the payoff balance

A = $1,000(1 + 0.1775)^5 = $2,263.63
