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

What is 6(5j + 4 + 3j) after using distributive property. Please explain your answer.

Answers

Answer:

Step-by-step explanation:

30j + 24+ 18j

48j + 24

Answer:

48j+24

Step-by-step explanation:

6(5j + 4 + 3j)

when there is a number outside of the parenthesis you have to multiply everything in the parenthesis by that number

6x5j=30j

6x4=24

6x3j=18j

so now we are left with 30j+24+18j

the final step would be to combine like terms

the only like terms are 30j and 18j

30j+18j=48j

so the final answer is

48j+24

hope this helps (:

A) 20/77

B) 30/121

Answers

The answer would be A)20/77.
The reason is that without replacement it would go (10/22)*(12/21)=0.2597
You can do the easy route I did then do (20/77) which would also give you 0.2597.

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:

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
