ARI AND KITT LET ME POST THE QUESTION

Using the graph shown, answer this question: What is the scale factor used to dilate the figure?

5. anonymous

count the length of the sides for each rectangle

6. anonymous

Okay. Let me count.

7. anonymous

just one side?

8. anonymous

yea, just make sure they're corresponding. like, the long side of the big one and long side of the small one

9. anonymous

Okay.

10. anonymous

let ari take over, I got nothing lol.

11. anonymous

Will it be by 2's or ones?

12. anonymous

it's by 1's

13. anonymous

Okie, Kitt. I like ur picture too

14. anonymous

always assume by 1's if it's not labeled

15. anonymous

Okie, Ari

16. anonymous

Can it be CB an CB'?

17. anonymous

(' Means the dilation or second version of a figure.)

18. anonymous

yea count them. then put cb/cb' and figure out the scale factor

19. anonymous

Ok.

20. anonymous

$\frac{ CB }{ CB' } = \frac{ 9 }{ 2 }$

21. anonymous

?

22. anonymous

So is the scale factor 4.5?

23. anonymous

(I divided 9/2)

24. anonymous

9/3

25. anonymous

O

26. anonymous

Okiee.

27. anonymous

which would give us scale factor of 3

28. anonymous

Ohhh. Okay. So answer = 3?

29. anonymous

wait no. put cb'/cb which would be 1/3

30. anonymous

31. anonymous

OH. OK. WHY WAS THE FIRST ONE WRONG?

32. anonymous

because if we said the scale factor was 3, then cb' would be 3x the size of cb. but it's not. it's 1/3 the size.

33. anonymous

Oh. Okay. Thanks!

34. anonymous

[since its smaller it can't b 3 times the size right?]

35. anonymous

TNX U

36. anonymous

lol yes

37. anonymous

:)

38. anonymous

no problemo
