$\bf t=165x+2771\qquad 
\begin{cases}
x=\textit{years since 1996}\\
t=\textit{tuition average fees}\\
----------\\
t=5576
\end{cases}
\\\\\\
5576=165x+2771\implies 5576-2771=165x\implies 2805=165x
\\\\\\
\cfrac{2805}{165}=x\implies \boxed{17=x}\\\\
-----------------------------\\\\
1996+\boxed{17}\implies 2013$

the volume of a triangular prism is 42 cubic centimeters. what is the volume of a similar prism that is twice as large as large

Dmitriy789 [7]

Answer:

The volume of the similar prism is $336\ cm^{3}$

Step-by-step explanation:

we know that

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

Let

z-----> the scale factor

x----> the volume of the larger prism

y----> the volume of the smaller prism

so

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

In this problem we have

$z=2$ -----> the scale factor

$y=42\ cm^{3}$

substitute and solve for x

$x=42(2^{3})=336\ cm^{3}$
