Your model locomotive is 18 inches long. it is an exact model of a locomotive that is 72 feet long. a window on the locomotive is how many times wider than a window on the model?

4

Step-by-step explanation:

Given: The length of a model locomotive = 18 inches

The length of a exact locomotive = 72 inches

The scale factor to scale the model of the locomotive is given by the ratio of the length of the locomotive to the length of the model.

let k be the scale factor, then

Hence, the dimensions of the locomotive model is 4 times the dimensions of the model.

Therefore, the locomotive is 4 times wider than a window on the model.

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
