Answer:

$1.12

Step-by-step explanation:

When you multiply 8/7 of 56, you get 64.

This shows that you will need 64 paperclips to make 56 inches worth of paper clips. If each paper clip costs two cents, you need to multiply 56 paperclips by 2 cents. 56x0.02=1.12 so it will cost you 1 dollar and twelve cents

Natalka [10]

Answer: 3x^4 +x^3 -2x^2 +3x +2

Step-by-step explanation:

(3x^4 - 2x^3 + 4x -2) + (3x^3 - 2x^2 - x +4)

There are no like terms for 3x^4, so leave it alone.

-2x^3 + 3x^3 = 1x^3

No like terms for -2x^2

4x - x = 3x

-2 + 4 = 2

Answer? 3x^4 +x^3 -2x^2 +3x +2

A cylindrical container has a diameter of 5 inches and a height of 12 inches. The container will be wrapped and delivered as a g
Anna71 [15]

Answer:

Step-by-step explanation:

1. Write your formula

2. Plug it in

3. Solve

these steps will help you out with all of your surface area problems.

Like this

Since it is a <u>diameter</u> you have to divide the diameter by 2. That will get you your radius. Then you write your formula for a cylinder. Your formula is...

V = Bh                            (Pie is also known as 3.14)

your big (B) is (pie times r squared) Then you add your height.

so your formula will look like this...

V = pie times r squared...

the full formula will be...

V = (3.14) times (2.5 squared) times the height which in this case is (12)

everything together will be...

V = (3.14) (2.5^2) (12)

all you have to do is multiply all of that and you will get your answer.

The answer is...

V = 236 inches ^2                        (Just a tip, the ^ sign means to the power of)
