Homework Help: Math

Posted by ♫J.R.♫ on Wednesday, May 9, 2012 at 8:39pm.

An artist draws a picture of a house with a rose bush in front. In his picture the rose bush is 1.5cm high and the house is 7.5cm high. In reality the rose bush is .75 metres high. How tall is the house (in metres)?

x = artist's scale

Convert meters to centimeters

In reality, rose bush = .75m * 100 cm/m = 750 cm

Solve for x
1.5x = 750
x = 750/1.5
x = 500 cm

IF artist's scale = 1 cm:500cm THEN
house = 7.5cm * 500 cm
= 3750 cm
= 3.75 m
