jolli1 [7]

Answer:

  7/9

Step-by-step explanation:

In order to write the fraction without any units (as a pure number), we must have units in the numerator and denominator that are the same. Then the units cancel.

<h3>Convert to gallons</h3>

We are given the conversion ...

  4 quarts = 1 gallon

Multiplying by 7, we see ...

  28 quarts = 7 gallons

<h3>Ratio</h3>

This lets us write the desired fraction as ...

  (28 quarts)/(9 gallons) = (7 gallons)/(9 gallons) = 7/9

The ratio in simplest form is 7/9.

Which choice is equivalent to the quotient below shown here when x&gt;0?
qwelly [4]

Answer:

Choice B is correct

Step-by-step explanation:

The given radical division can be expressed in the following form;

\frac{\sqrt{16x^{3} } }{\sqrt{8x} }

Using the properties of radical division, the expression can be expressed in the following form;

\sqrt{\frac{16x^{3} }{8x} }=\sqrt{2x^{2} }

Simplifying further yields;

\sqrt{2x^{2} }=\sqrt{2}*\sqrt{x^{2} }=x\sqrt{2}

Choice B is thus the correct alternative
