Find the scale factor for the similar figures.

OpenStudy (alexandervonhumboldt2):

scale factor=Side of new figure/side of old figure

OpenStudy (matthew120):

OpenStudy (matthew120):

|dw:1448921506651:dw|

OpenStudy (alexandervonhumboldt2):

divide one side of new figure by corresponding side of old figure

OpenStudy (ghostgate):

Alexander is right again, simply divide the old factors by the new factors measurements. Just like if something was 2x2 and you now have 8x8, divide 8 by 2 to get 4, so your scale factor would be 4.

OpenStudy (ghostgate):

I meant new divided by old. :/

OpenStudy (alexandervonhumboldt2):

old figure*scale factor=new figure 6*x=1.5 x=1.5/6=?

OpenStudy (matthew120):

0.25

OpenStudy (ghostgate):

Yep, that's the answer. Good job.

OpenStudy (matthew120):

nope it not

OpenStudy (alexandervonhumboldt2):

what figure is new?

OpenStudy (alexandervonhumboldt2):

first or second one?

OpenStudy (matthew120):

what 1/4 is 0.25 right

OpenStudy (ghostgate):

In other words is the new one 1.5x2 or 6x8?

OpenStudy (alexandervonhumboldt2):

1/4=0.25 yeah

OpenStudy (matthew120):

oh

OpenStudy (matthew120):

i am really dumb

OpenStudy (ghostgate):

The only alternative I can think of if that is also wrong is that it's the area of the new one divided by the area of the second one, which results in 0.0625.

OpenStudy (matthew120):

Use the scale factor to find the length of the image. scale factor: 8 length of figure = 10 yd length of image =
