<h3>Answer: Radius = 6 inches</h3>

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

Explanation:

Let r be the radius we want to find

The area of the full circle is A = pi*r^2

The unshaded portion is 60 degrees, so the unshaded portion must be 360-60 = 300 degrees.

The full area was pi*r^2, but we only want 300/360 of that full area.

So,

s = shaded area

s = (300/360)*(full circle area)

s = (300/360)*(pi*r^2)

s = 30pi

(300/360)*(pi*r^2) = 30pi

(300/360)*r^2 = 30

(5/6)*r^2 = 30

5r^2 = 30*6

5r^2 = 180

r^2 = 36

r = sqrt(36)

r = 6

The radius is 6 inches.

Answer: D) 3x - 5

Step-by-step explanation:

f(x) - g(x)
f(x) = 1/2x - 3
g(x) = -5/2x + 2

Using the values of f(x) and g(x) gives us the equation:
1/2x - 3 - (-5/2x +2)

By distributing the negative sign, the signs on 5/2 and 2 are flipped, making them positive and negative respectively.

Our new equation is:

1/2x -3 + 5/2x -2
Adding up like numbers gives us:

6/2x - 5

Simplifying 6/2x => 3x

So our final equation is:

3x - 5
Hope this helps!

Prudential Realty has an escrow account for one of its property management clients that contains $20,000. How long will it take
ASHA 777 [7]

Answer:

It will take 4 years to deplete the account.

Step-by-step explanation:

Prudential Reality has an escrow account that contains $20,000.

The client withdraws $5000 now and that leaves $15000.

After one year an amount of $4500 is withdrawn which leaves ($15000 - $4500)  = $10500

After two years an amount of $4000 is withdrawn which leaves ( $10500 -$4000) = $6500.

After three years an amount of $3500 is withdrawn which leaves ( $6500 - $3500) = $3000

After four years an amount of $3000 is withdrawn which leaves ($3000 - $3000) = $0 in the account.

Hence it will take 4 years to deplete the account.
