A music store is having a clearance sale. All items are discounted by 20%. What is the sale price of a radio that regularly costs $30?

Answers

Answer:

24

Step-by-step explanation:

You would first multiply 20% by $30. Then you would get 6 and subtract 6 from $30.

Answer:

$24

Step-by-step explanation:

Method 1: find 10% of 30 = 3 (just divide 30 by 10)

then double it to make 20% = 6

subtract 6 from 30 to give 24.

Method 2: 20% = 1/5

To find 1/5 of a number, divide it by 5.

30 divided by 5 = 6.

Then subtract 6 from 30 = 24.

Method 3: to decrease a number by 20% multiply it by 0.8.

30 x 0.8 = 24

A circle has a circumference of 16π yards. Find the area in terms of π (pi).

Answers

64 pi. Since the formula for the circumference of a cirlcle is: pi x diameter. The diameter of the circle would be 16. And the radius of that would be 8 since its half of 16. The formula to find the area is: pi x radius squared. So 8 squared pi would be 64 pi.

64 pi is the answer if I’m correct
