Answer:

-3/2

Step-by-step explanation:

In the picture attached, the complete question is shown.

The expression is:

\frac{ \frac{1}{2} }{ \frac{-2}{5}} + \frac{-1}{4}

You can rewrite the first term, expressing the division as a multiplication, that is, inverting the fraction in the denominator, as follows:

\frac{1}{2} \times \frac{-5}{2}+ \frac{-1}{4}

\frac{-5}{4} + \frac{-1}{4}

The addition of a negative fraction is simply the subtraction by that fraction:

\frac{-5}{4} - \frac{1}{4}

\frac{-5 - 1}{4}

\frac{-6}{4}

Which can be simplified dividing by two both numerator and denominator:

\frac{-3}{2}

KonstantinChe [14]

Volume of a rectangular prism = l × w × h.

In this case,

V = 270 cubic feet

l = 15 feet

w = 4 ft

h = ?

Plug our values into the volume formula.

270 cubic feet = 15 feet × 4 feet × h.

Simplify the right side

270 = 60 × h.

Divide each side by 60.

4.5 = h

The height is 4.5 feet.
