5 0

Answer:

1271.7in

Step-by-step explanation:

A complete rotation is = circumference of the wheel.

So calculate the circumference which is pi times diameter.

27 times pi (which is 3.14) = 84.78in   one rotation

so if you make 15 rotations, you are multiplying it by 15

15 x 84.78 = 1271.7in

If 2 over 5 tons of concrete covers 5 over 6 of a wall, how many tons of concrete are required to cover the entire wall?
Dominik [7]

Answer:

A. 12.25 tons

Step-by-step explanation:

We will let x represent the amount required to cover the entire wall.

We can divided 2/5 by 5/6 to solve for x

2/5 divided by 5/6=x

When you divide by a fraction, you can always multiply by the reciprocal (flipped number).

Our new equation is:

2/5·6/5=12/25

What is 9.33 as a fraction
kvv77 [185]
Well,

We can read 9.33 as 9 and 33 hundredths.

In fraction form that would be:
9  \frac{33}{100}

That is already simplest form.

If you meant 9. \overline{3}, then it would be:
9  \frac{1}{3}

3241004551 [841]

9514 1404 393

Answer:

  about $171,400

Step-by-step explanation:

William's total monthly debt is ...

  $1012.84 +579.13 +250 +300 = 2141.97

On an annual basis, this is ...

  12 × $2141.97 = $25,703.64

This will be 15% of (25703.64/0.15) = $171,357.60.

William's new annual salary should be about $171,400 to keep his debt ratio at the recommended 15%.

_____

<em>Additional comment</em>

A debt ratio of 15% is a pretty aggressive target. Most mortgage lenders like to see the "front end" ratio (housing expense) less than 28%, and the "back end" ratio (all debt) less than 36%.
