Question #727d8

Answer 1

You didn't provide any choices for your question, but I'll provide an example below.

Explanation:

`100/1 / 12/1= n` Let `n=` how many feet per minute

Hope this helps! :)

Answer 2

Read below.

Explanation:

So we have: 100 inches per minute.

Now, we ask ourselves: how many feet is `100` inches?

We know that `12`in. `=` `1ft`

Since we want 100 inches, we multiply both sides by `100/12`

`12`in.`*100/12` `=` `1ft*100/12`

=>`100`in. `=` `100/12ft`

We simplify the fraction.

=>`100`in. `=` `25/3ft`

=>`100`in. `=` `8 1/3ft`

Therefore, `100`inches per minute is equal to `8 1/3` feet per minute.

Answer 3

`"100 in/min"` is equal to `8 1/3" ft/min"`.

Explanation:

Use dimensional analysis.

Write an equation showing how feet and inches are related.

`"1 ft"` `=` `"12 in"`

This will give two conversion factors:

`"1 ft"/"12 in"` and `"12 in"/"1 ft"`

Since we want to end up with feet/minute, multiply `"100 in/mi"` by the conversion factor that has feet in the numerator. This will cancel inches and leave feet.

`(100color(red)cancel(color(black)("in")))/"min"xx("1 ft")/(12color(red)cancel(color(black)("in")))` `=` `8.3bar3" ft/min"` `=` `8 1/3" ft/min"`
