Question

Help! i give medals will be below...
Find the scale factor of ABCDE to FGHIJ.

Answer 1

well if they are similar shapes, then they have an equal ratio of 10:15... which is 2:3

so x would be 9 * 2/3 and y would be 8 * 3/2

Answer 2

how do i type 2/3 into my calculator?? as a decimal??

Answer 3

well 2/3 is 0.66666666666666666666666666666666.... repeating

if you have a graphing calculator then you should be able to type in (2/3). also there are many online calculators that can do this

Answer 4

press: 2

press the divide key

press: 3

press enter or equals or whatever they want to call the finishing key

Answer 5

ok i though so but i didn't want to get the wrong answer thanks

Answer 6

for x i get 6 and for y k get 5.3

Answer 7

i mean y LOL @robz8

Answer 8

remember, when you're solving for y, you're not multiplying 8 by 2/3, you're multiplying it by 3/2 because y is on the larger shape

Answer 9

your x value is correct

Answer 10

oh so y is 12

Answer 11

correct

Answer 12

could you help me i have to more questions for this one

Answer 13

would i just do 38 times 2/3

then take 15 divided by 3/2 @robz8

Answer 14

are these questions referring to the same shapes?

Answer 15

yes i deleated them i will retype them

Answer 16

if the perimeter of ABCDE is 38 find the perimeter of FGHIJ

if length HJ is 15 find length CE

Answer 17

for the perimeter you would multiply by 3/2, not 2/3 to find FGHIJ

Answer 18

and for HJ you would just do 15 *2/3, or like you said, 15 divided by 3/2

Answer 19

Ok thanks so much for the help i really appreciate it :)

Answer 20

you're welcome!
