@jim_thompson5910

Answer 1

you're missing the figures

Answer 2

or the following questions

Answer 3

sorry i keep getting distracted

Answer 4

that's ok

Answer 5

AB corresponds to FG

Answer 6

So FG/AB = 6/8 = 0.75 is the number you multiply each side length in the larger pentagon to get the corresponding side length in the smaller pentagon

Answer 7

8?

Answer 8

8 times 0.75 = 6

Answer 9

oh wait, i read that wrong...one sec

Answer 10

oh for some reason, it still works out...lucky coincidence

but yes, you multiply by 0.75

Answer 11

oh

Answer 12

to go backwards, you divide by 0.75

Answer 13

notice how FJ corresponds to AE

Answer 14

and FJ = 6

So AE = FJ/0.75 = 6/0.75 = 8

which means AE = 8

Answer 15

so then i had it right?

Answer 16

yes, sry i didn't see that til now

Answer 17

ok, cool and for #14 it would be 2.5?

Answer 18

no no no it would be 3

Answer 19

which side corresponds to IJ?

Answer 20

CD, so it would make it 3? correct?

Answer 21

this is why this problem is a bit confusing

Answer 22

the second pentagon should be rotated slightly clockwise so that FG matches up with AB

Answer 23

now tell me what ij corresponds to

Answer 24

8

Answer 25

did you do the rotation? this will make F the bottom most point

Answer 26

yea

Answer 27

so ij corresponds to ???

Answer 28

which side from ABCDE

Answer 29

de

Answer 30

good

Answer 31

now multiply that length by 0.75 to find ij

Answer 32

2.5

Answer 33

try it again

5 times 0.75 = ???

Answer 34

de = 5

Answer 35

3.75

Answer 36

good

Answer 37

fg would be 4?

Answer 38

fg corresponds to ???

Answer 39

ab?

Answer 40

good

FG = 0.75 times AB

Answer 41

6

Answer 42

you nailed it

Answer 43

thanks, this will be the last one i promise

Answer 44

The two triangles are similar

So

AD/ED = BD/CD

35/16 = 25/x

Now solve for x

Answer 45

9.6?

Answer 46

no

Answer 47

35/16 = 25/x

35x = 16*25

Answer 48

7 6/7

Answer 49

no it's not any of those answer choices

Answer 50

x is the length of CD

Answer 51

which isn't listed

Answer 52

16*25=400

Answer 53

good

Answer 54

35x = 16*25

35x = 400

Answer 55

dfsdfdddddddd

Answer 56

sorry cat walked on the kep board... and i dont get wat i do next

Answer 57

key*

Answer 58

that's ok, divide both sides by 35

Answer 59

45 divided by 35, and what else by 35?

Answer 60

11.4

Answer 61

ok now subtract this from 25

Answer 62

13.6

Answer 63

which is closest to which answer choice?

Answer 64

13 4/7

Answer 65

13.6 is closest to 13 6/7

Answer 66

your first response is correct
