For this scientific investigation you want to find out if a paper airplane, fish tank or science simulation on skateboarding is a good model for a certain parameter of your choosing. Choose which one of the models you are most interested in exploring (only 1 is required, but you are welcome to consider the other two if they interest you). Here are some resources to help you for each type of model. Your goal is to find one testable experiment you can do with the model and then compare that to a real airplane, the ocean or how actual skateboarding works. Will your hypothesis be that it is a good model or poor model for the parameter of your choosing

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total

168

step-by-step explanation:

i am pretty sure that the answer is 168

your answer would be 12

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
