if the ratio of the areas of 2 similar polygons is 32:50, what is the ration of the corresponding side lengths?

$\bf \qquad \qquad \textit{ratio relations}
\\\\
\begin{array}{ccccllll}
&Sides&Area&Volume\\
&-----&-----&-----\\
\cfrac{\textit{similar shape}}{\textit{similar shape}}&\cfrac{s}{s}&\cfrac{s^2}{s^2}&\cfrac{s^3}{s^3}
\end{array} \\\\
-----------------------------\\\\
\cfrac{\textit{similar shape}}{\textit{similar shape}}\qquad \cfrac{s}{s}=\cfrac{\sqrt{s^2}}{\sqrt{s^2}}=\cfrac{\sqrt[3]{s^3}}{\sqrt[3]{s^3}}\\\\
-------------------------------\\\\$

$\bf \cfrac{small}{large}\qquad \cfrac{s}{s}=\cfrac{\sqrt{s^2}}{\sqrt{s^2}}\implies \cfrac{s}{s}=\cfrac{\sqrt{32}}{\sqrt{50}}\implies \cfrac{s}{s}=\cfrac{\sqrt{16\cdot 2}}{\sqrt{25\cdot 2}}
\\\\\\
\cfrac{s}{s}=\cfrac{\sqrt{4^2\cdot 2}}{\sqrt{5^2\cdot 2}}\implies \cfrac{s}{s}=\cfrac{4\sqrt{2}}{5\sqrt{2}}\implies \cfrac{s}{s}=\cfrac{4}{5}$

40/.10

okay so plan 1 is 20$ a month plus .10 cent each message

plan 2 40$ unlimited text.

now 20 is half of forty , so another 20 to get to 40

20/.10 gives you 200 messages until you reach the 40 dollar mark.
