The ratio of volumes is equal to the ratio of the cubes of the scale factor. Thus,
Volume ratio:
6³ : 7³
216 : 343

Answer:

The ratio of their volumes is equal to \frac{216}{343}  

Step-by-step explanation:

we know that

If two solids are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z-----> the scale factor

x/y----> the ratio of its volumes

so

z^{3}=\frac{x}{y}

we have

z=\frac{6}{7}

substitute

(\frac{6}{7})^{3}=\frac{x}{y}

(\frac{216}{343})=\frac{x}{y}

rewrite

\frac{x}{y}=(\frac{216}{343}) -----> the fraction is irreducible

You deposit $5000 in an account earning 8% interest compounded monthly. How much will you have in the account in 15 years?
Rasek [7]

\bf ~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$5000\\ r=rate\to 8\%\to \frac{8}{100}\dotfill &0.08\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{monthly, thus twelve} \end{array}\dotfill &12\\ t=years\dotfill &15 \end{cases}

\bf A=5000\left(1+\frac{0.08}{12}\right)^{12\cdot 15}\implies A=5000(1.00\overline{66})^{180}\implies A\approx 16534.61
