A girl is 6 years older than her brother than her brother. In 3 years she will be 2 years older than twice what his age will be then. What are their ages now?

Answers

Answer:

1 = brother's age now.

4 = brothers age in 3 years.

7 = girls age now.

10 = girls age in 3 years.

Step-by-step explanation:

You want to get x by itself first.

(x + 6) + 3 = 2(x + 3) + 2

x +9 = 2x + 8

-x + 9 = 8

-x = -1

x = 1

This is her brothers age when she is 6 years older than him.

Now you will take the 1 and put it in the x +3 = brother's age in 3 years.

The brother will be 4 in 3 years.

The girl will be 7 when her brother is born.

Then you will take the 1 and put it into (x + 6) +3 = 10.

The girl will be 10 in 3 years.

1 = brother's age now.

4 = brothers age in 3 years.

7 = girls age now.

10 = girls age in 3 years.

A can of juice has a radius of 7 inches and a height of 8 inches. What is the volume of the can?

Answers

Answer:

V = 392 pi in^3 or approximately 1230.88 in^3

Step-by-step explanation:

The volume of a can, which is a cylinder, is given by

V = pi r^2 h

= pi (7)^2 * 8

= pi *392

We can approximate pi by 3.14

V = 392 * 3.14

=1230.88 in^3
