Question

an ostrich is 255 cm.Suppose that you want to make a scale drawing of an ostrich. The scale is 30:1. What height will you make the ostrich in your drawing

Answer 1

The height of the drawing should be: 8.5 cm

Explanation:

Use the proportion given by the scale in order to find the height "h" that you need to draw:

`(30)/(1) =(255)/(h) \\30=(255)/(h)\\30\,h=255\\h=(255)/(30)\\ h=8.5\,\,cm`
