80 members decreased by 40%

aleksklad [387]

The answer would be 48 because....

First, you would multiply 80 and .40 (changed the percentage to decimal) which is 32

Then, subtract 80 and 32 to get 48

Find the length of the line segment inside the rectangular prism.

disa [49]

To find the length of the yellow segment, we have to use Pythagorean's Theorem. But first, we have to find the length of the black line at the bottom.

$c^2=a^2+b^2$

Where a = 4ft and b = 9ft.

$\begin{gathered} c^2=4^2+9^2 \\ c^2=15+81 \\ c=\sqrt[]{96} \\ c\approx9.8 \end{gathered}$

So, the length of the black segment is 9.8 feet.

Now, we find the yellow line length

$c^2=a^2+b^2$

Where a = 4 and b = 6.

$\begin{gathered} c^2=4^2+6^2 \\ c^2=16+36 \\ c^2=52 \\ c=\sqrt[]{52} \\ c\approx7.2 \end{gathered}$ <h2>Therefore, the length of the yellow line is 7.2 feet.</h2>
