Question

ms. Omar runs the school tennis club. She has a bin of tennis balls and rackets. For every 5 tennis balls in the bin, there are 3 tennis rackets. Draw a model to show the ratio of tennis balls to tennis rackets.

Answer 1

see the explanation

Explanation:

Let

x ----> number of tennis balls

y ----> number of tennis rackets

we know that

To find out the ratio of tennis balls to tennis rackets, divide the number of tennis ball by the number of tennis rackets

In this problem we have

`(x)/(y)=(5)/(3)`

see the model in the attached figure N 1

so

`y=(3)/(5)x`

`y=0.60x`

This is the equation of a linear direct variation

The relationship between the variables x and y is proportional

see the model in the attached figure N 2
