An F-15 fighter jet is 63 feet long. What is the length of a model of the jet if the scale factor is 1 inch:9 feet?

7 Inches

Step-by-step explanation:

63 feet divided by 9 feet gives you 7, it's a 7 inch long model.

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
