Answer:

You add all the values together.

Step-by-step explanation:

Each quarter is 25 cents. You should know that four quarters make a dollar.

25 * 4 = 100

Now you have two quarters left which makes 50 cents.

Add the 9 dimes and you have 90 cents.

9 * 10 = 90

And 4 pennies which equals 4 cents.

Now add.

50 + 90 + 4 = 1.44

Now add the whole dollar from the first step and now you have $2.44. Two dollars and forty four cents.

Hope this helps, have a good day/night and stay safe and healthy.

What is the sum of three consecutive even numbers is 30?
kykrilka [37]
8, 10, 12

A helpful equation:
x+x+1+x+2 = 30

Combine like terms
3x + 3 = 30

Subtract 3 from each side
3x = 27

Divide each side by to isolate x
x = 9

x = 9. However, 9 is not an even number. Let’s subtract 1 from 9 to get the first even number.

The first number is 8. The best two even numbers after 8 are 10 and 12.

8 + 10 + 12 = 30, thus this is the sequence.

What is the volume of a 14 in diameter pipe that’s 2156 long?
storchak [24]

Answer:


Step-by-step explanation:

given that diameter of the pipe = 14 inches

radius = 7 inches

Length =2156 inches

Pipe is in the form of a cylinder

Volume of cylinder = pi r^2 h

where r = radius and h = l = 2156

We have to substitute the values of r and h.

Let us take pi as 22/7

= 22/7 (7)(7)(2156)

Cancel out 7 and multiply the remaining 22 ,7 and 2156

=332024 cubic inches
