Question

Given: ABC is similar to XYC. Enter answer as a decimal.

If BY = 5, BC = 20, AC = 18, then XC =

Answer 1

cant really determine a picture from this; you have a BY that might be a typo

Answer 2

it is by

Answer 3

is this a triangle inside another? with either AB or XY in the middle as a line segment?

Answer 4

XY IS in the middle yes

Answer 5

BA, is the left side of this then; B up top?

Answer 6

yep correct

Answer 7

that is right

Answer 8

5 = 20
------ n = 5(18)/20
n = 18

n = 18/4

20 - 18/4 = 80-18/4 = 62/4 .... is that an option :)

Answer 9

15.5

Answer 10

one second

Answer 11

nope its not right i dont know why :/

Answer 12

i spose we coulda went an easier route and did:

15=20
------
n = 18

n = 15(18)/20 = 3(18)/4 = 3(9)/2 = 27/2 = 13.5 .....

Answer 13

i hit the 5 instead of the 3 ....

Answer 14

corecct :D

Answer 15

would u mind helping me with one more your the only one that seemd to be able to help me

Answer 16

i can try....

Answer 17

The sides of a polygon are 3, 5, 6, 8, and 10. The perimeter of a similar polygon is 40. Find the sides of the second polygon (from smallest to largest). Put answers in decimal form (hundredths).

Answer 18

k(3+5+6+8+10) = 40

k = 40/32 = 20/16 = 10/8 = 5/4

the sides are:
(2)(1)
3(5)/4 = 3.75
5(5)/4 = 6.25
6(5)/4 = 7.5
8(5)/4 = 10
10(5)/4 = 12.5
--------------
40.00 adds up lol

Answer 19

correct you dont know how much your helping e i been stuck on this stuff for like a week

Answer 20

did you try yelling at it?

Answer 21

haha yes

Answer 22

Given: rectangle ABCD is similar to rectangle ZBXY. Enter answer as a simplified, improper fraction.

If BX = 8, BZ = 3, DC = 5, then XC = now i tryed this one but i dont get what i did wrong arent you supposed to cross mulitply

Answer 23

where do i put the letters?

Answer 24

bxc at the top then zy under it then ad at the bottom

Answer 25

good enough?

Answer 26

my computer froze....

Answer 27

a is to 8
-------
5 is to 3

Answer 28

a = 40/3 ; its a corss multiply yeah then

8 + 40/3 = 8(3) +40/3 = 24+40/3

XC = 64/3

Answer 29

nope :/

Answer 30

then the diagram aint right :)

Answer 31

hm

Answer 32

Given: rectangle ABCD is similar to rectangle ZBXY. Enter answer as a simplified, improper fraction.

If ZY = 5, XC = 3, DC = 4, then XY =

Answer 33

thats all i got

Answer 34

and how does that match up with the graph i posted of it?

Answer 35

that is a different problem than th one you posted right before

Answer 36

oh sorry
