Atrain car is 16 feet long. what is the model length if 3 inches = 8 feet

Explanation:

We are told that

3 inches = 8 feet

so we can multiply both sides by 2 to get

6 inches = 16 feet

or you can solve the proportion below for x

3/8 = x/16

3*16 = 8*x cross multiply

48 = 8x

8x = 48

x = 48/8 divide both sides by 8

x = 6

ryan had a head start of 10 meters.

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
