for art class, you have constructed a model of your family's car. if your model is 4 inches high and your car is 5 feet high, what scale factor did you use?
To find the scale factor, you need to determine the ratio of the height of the model to the height of the actual car.
First, convert the height of the car to inches:
5 feet = 5 * 12 = 60 inches
Then, calculate the scale factor:
Scale factor = height of model / height of actual car
Scale factor = 4 inches / 60 inches
Scale factor = 1/15
Therefore, the scale factor used for the model of your family's car is 1:15.
