Slope of 4/5, a width of 30…what is the height..?

maw [93]

$\qquad\qquad\huge\underline{{\sf Answer}}$

Here we go ~

Slope of the graph can be expressed as :

$\qquad \sf \dashrightarrow \:slope = \tan( \theta) = \dfrac{4}{5}$

$\qquad \sf \dashrightarrow \: \dfrac{x}{30} = \dfrac{4}{5}$

$\qquad \sf \dashrightarrow \: x = \dfrac{4}{5} \times 30$

$\qquad \sf \dashrightarrow \: x = {4}{} \times 6$

$\qquad \sf \dashrightarrow \: x = 24 \: units$

So, the value of x is 24 units

The pair of square pyramids are similar. Use the given information to find the scale factor of the smaller square pyramid to the

Mrrafil [7]

$\bf \qquad \qquad \textit{ratio relations}
\\\\
\begin{array}{ccccllll}
&\stackrel{ratio~of~the}{Sides}&\stackrel{ratio~of~the}{Areas}&\stackrel{ratio~of~the}{Volumes}\\
&-----&-----&-----\\
\cfrac{\textit{similar shape}}{\textit{similar shape}}&\cfrac{s}{s}&\cfrac{s^2}{s^2}&\cfrac{s^3}{s^3}

$\bf \cfrac{\textit{similar shape}}{\textit{similar shape}}\qquad \cfrac{s}{s}=\cfrac{\sqrt{s^2}}{\sqrt{s^2}}=\cfrac{\sqrt[3]{s^3}}{\sqrt[3]{s^3}}\\\\
-------------------------------\\\\
\stackrel{\stackrel{pyramids}{scale~factor}}{\cfrac{small}{large}}\qquad \qquad \cfrac{s}{s}=\cfrac{\sqrt[3]{64}}{\sqrt[3]{343}}\implies \cfrac{s}{s}=\cfrac{4}{7}\implies 4:7$
