Question

Benjamin is planning to make scale drawings of bat wings. He wants all of his drawings to use the same scale. He says he can use the equation d=1.5w to find the length of a scale drawing, d, based on the length of the bat wing, w. What is fhe scale factor of a bat wing length to scale drawing length? Explain.

Answer 1

`1.5` is the scale factor of a bat wing length to scale drawing length.

Explanation:

A scale factor is a number which multiplies (scales) , some quantity. In the equation
`y=kx`,
`k` is the scale factor for
`x`. Here,
`k` is called as the constant of proportionality of
`y` to
`x`.

Consider the equation
`d=1.5w`

Here, d denotes the length of a scale drawing and w denotes the length of the bat wing.

So,

`1.5` is the scale factor of a bat wing length to scale drawing length.
