Question 1 of 10 A toy car that is 0.5 ft long is used to model the actions of an actual car that
is 15 ft long. Which ratio shows the relationship between the sizes of the
model and the actual car?

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

come closer and become far apart and become steam/gas
