Zane measured a city and made a scale drawing. The scale of the drawing was 9 inches=3 yards. What scale factor does the drawing use?

1:12

Step-by-step explanation:

To simplify 3 yards :

3 yd.* 36 in. = 108 inches

9:108 simplified :

9/9 = 1

108/9 = 12

So, the ratio for the scale factor is 1:12 :)

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
