Question

A 5-foot tall student stands 10 feet away from the lens of a camera. The film of the camera is 1 inch away from the lens.
what is the length of the film?

Answer 1

The distance of the child from the lens is 10 times the amount of the length of the film to the lens. What is a number that you multiply by 10 to get 5?

Answer 2

2?

Answer 3

You did that backwards lol, it's easier to say, divide 5 by 10 to get your number, it's proportion.

Answer 4

ok so can you show me like step by steps so i can understand it a little bit better?

Answer 5

0.5 inches
0.7 inches
1.5 inches
1.2 inches
these are the choices...and i kno its not 1.2 or 1.5 because i got those two wrong and so its either 0.5 or 0.7 but idk how to get to that so thats why i want to see like step by step so i understand and know how to do it

Answer 6

In proportion, look for the relations between the two shapes you're given. In this case, from the smaller to the larger one, we multiply by 10. since 1 and 10 are related to each other. We see that 5 and the film length are related. If we relate the big triangle to the smaller one, it is 0.1 times as big, since 10 x 0.1 = 1 then we know 5 x 0.1 = 0.5

Answer 7

thank you so much i totaly understand now (:
