The price of a car has been reduced from $15,000 to $9,000. What is the percentage decrease of the price of the car?

Fynjy0 [20]

Answer:

$40$ % is the decrease.

Step-by-step explanation:

To figure out the percentage decrease, you would first subtract the two numbers.

$15000 - 9000 = 6000$

Next, you would divide that number by the total.

$6000 / 15000 = .4$

$15000 * .4 = 6000$

$15000 - 6000 = 9000$

$40$ % would be the decrease percentage.

MariettaO [177]

Answer:

b 19.2

Step-by-step explanation:

a = $\pi$ $r^{2}$ for a circle. We do not want to find the area for a whole circle. We only want to find the area for part of a circle. a hole circle is 360 degrees.

a = $\frac{88}{360}$ $\pi$ $r^{2}$

a = $\frac{88}{360}$ $\pi$ ( $5^{2}$ )

a = 19.2 rounded.
