Step-by-step explanation:

Scale factor = 4/3. Therefore radius if larger cone = 4r/3 where r is the radius of the smaller cone and height of larger cone = 4h/3 where h is the height of the larger cone.

So ratio of volumes = r^2 * h/(4r/3)^2 * 4h/3) = 9/16 * 3/4 = 27/64

30 is a similar process except it's cylinders so find the scale factor and go on with that problem.

A salesperson sells $2100 in merchandise and earns a commission of $273, What is the commission rate?
larisa86 [58]

if we take 2100 to be the 100%, what is 273 off of it in percentage?

\begin{array}{ccll} amount&\%\\ \cline{1-2} 2100 & 100\\ 273& x \end{array} \implies \cfrac{2100}{273}=\cfrac{100}{x}\implies \cfrac{100}{13}=\cfrac{100}{x} \\\\\\ 100x=1300\implies x=\cfrac{1300}{100}\implies x=13
