Question

Identify the independent and dependent variables. The equation A=25w gives the area A (in square feet) of a rectangular dance floor with a width of w feet.

Answer 1

The dependent variable is A

The independent variable is w

Explanation:

Given

`A = 25w`

Required

Identify the variables

In
`A = 25w`

The value of w is independent of the value of A.

In other words:

A derive its own value from w; by multiplying 25 and w.

Take for instance:

`w = 3`

The value of A would be:

`A = 25 * 3`

`A = 75`

Hence:

The dependent variable is A

The independent variable is w
