Answer:

<h2>answer c: 10</h2>

Step-by-step explanation:

v=H*W*L

280=7*W*(6+W)

280=42W+7W^2

40=6w+w^2

W^2+6W-40=0

(W-4)(W+10)=0

W=4

We can only use positive results

L=6+W

L=4+6=10

=10

What is 0.3111111111111111 as a fraction?
Citrus2011 [14]
\sf~N=0.3\overline{1}

There is only one repeating number, so we multiply both sides by \sf10^1 or \sf10.

\sf10N=3.\overline{1}

Now subtract the original number we had to both sides, which is the same as \sf~1N or \sf~N

So we have:

\sf9N=2.8

Divide 9 to both sides:

\sf~N=\dfrac{2.8}{9}

Multiply the fraction by 10 to get rid of the decimal in the numerator.

\sf~N=\dfrac{28}{90}

Simplify the fraction by dividing the numerator and denominator by 2:

\sf~N=\boxed{\sf\dfrac{14}{45}}
