Chapter 10.1, Problem 28CCR

To determine

To calculate: Find the constant of proportionality that represents the data.

Answer to Problem 28CCR

Therefore, $\text{constant of proportionality=12}$ .

Explanation of Solution

Given information: The given data is,

Dodecahedrons	1	2	3	4
Sides	12	24	36	48

Calculation: The given data can be evaluated as,

  $\begin{array}{l}y=kx\\ \text{where k is proportionality constant}\text{.}\\ y_1=k{x}_1\\ 12=k\times 1\\ k=12\\ y_2=k{x}_2\\ 24=k\times 2\\ k=12\end{array}$

Therefore, $\text{constant of proportionality=12}$ .
