Answer 1

A company is looking to design a new cover for their smartphone. The scale drawing of the design is shown below. The coordinates of the actual cover are: H' (10,0); I' (0, 0); J' (0, 16); K' (10,16). Is the design of the cover similar to the actual cover?



Yes; the corresponding sides are proportional.
No; the corresponding sides are not proportional.
Yes; the corresponding angles are proportional.
No; the corresponding angles are not proportional.

Answer 2

The correct answer would be B correct? Because they arent proportional

Answer 3

Could you explain it too me? Just so i know we're on the same page

Answer 4

H = (2,0); I = (0,0); J = (0,4); K = (2,4)
H' = (10,0); I' = (0,0); J' = (0,16); K' = (10,16)


What's going on when we go from H to H' ?

Answer 5

its increasing by 8 units

Answer 6

2 times ______ = 10

what goes in the blank

Answer 7

5

Answer 8

so from H to H' the scale factor is 5

Answer 9

but if we go from J to J', and we apply the same scale factor, we don't have things match up

Answer 10

It would equal 4. So the other is 5 so B would be the correct answer

Answer 11

yes the two figures aren't proportional for this reason
