Mike is making a scale model of his favorite car. The actual car is 8 feet long and 4 feet wide. Mike wants his model to be 12 inches in length. Which could be used to find the width of his model if he uses the same ratio?
f 84=12x g 812=x4 h h 128=x4 j 84=x12
j 84=x12.
The correct ratio to use is:
8 feet = 96 inches (since 1 foot is 12 inches)
So, the ratio of the actual length to the model length is:
96 : 12, or 8 : 1
To find the width of the model using the same ratio, we can use:
8 : 1 = 4 : x
This is because we know that the actual width is 4 feet, and we want to find the width x of the model.
To solve for x, we can use cross-multiplication:
8x = 4 * 1
8x = 4
x = 0.5
So the width of Mike's scale model should be 0.5 feet, or 6 inches.
Therefore, the answer is not one of the options given, but rather:
k. 4:x = 8:1, x = 0.5.
