Question

Math help

Answer 1

TOO HARD

Answer 2

\[\frac{ 72 }{ 6 } = 12\]
Scale Factor: 12

Answer 3

AB =EF so ABCD = EFGH.

Answer 4

no that is the scale factor not the total.

Answer 5

Well,letssee the equivalence they gave you, E->F = 72 and A->B = 6. \[\frac{ 72 }{ 6 }=12\] so wouldnt our ratio, or common difference between each side be a 12x whatever angle is there?

Answer 6

@Jhannybean yes! that is what i said :)

Answer 7

So for each side of the big trapezoid, EFGH, you'd need to multiply each smaller side of ABCD by 12 to figure out the lengths of each big side

Answer 8

with that you can find the rest of the side lengths.
then find the total

Answer 9

i know @some_someone , i'm drawing a figure to help them.

Answer 10

okaii so: the scale factor is 12

AB = 6

6 * 12 = 72 = EF
----------------------

BC = 3

3 * 12 = 36 = FG

-------------------

Answer 11

@IxairaS do you understand now?

Answer 12

can you find the rest @IxairaS

Answer 13

yes! thats the spirit :)

Answer 14

like @some_someone mentioned,the scale factor is 12, so you multiply each unknown side by 12 to figure them out.

Answer 15

No problem. Good luck with your class

Answer 16

Sure thing

Answer 17

Sure is.

Answer 18

okay next one :)

I think its either A or D

Answer 19

For this one, you need to understand the area of a square. Do you know how to find the area of the square?

Answer 20

No

Answer 21

When they mean the area of the folded paper is halved, they're saying if you take the 4 triangles that circumscribed around the square, you can combine them to get 2 more squares. to all together you would have 3 squares.

Answer 22

Is it B

Answer 23

Yes. How did you get B, though?

Answer 24

I found the area of the square

Answer 25

The area of a square can be found by multiplying the base times itself.

Answer 26

Can we do another ones

Answer 27

Yes :)

Answer 28

Good job

Answer 29

For 34, The Area of a rectangle is = ?

Answer 30

A=1/2*b*h

Answer 31

No, no, that's the area of a triangle.

Answer 32

omg sorry read wrong a=L*W*

Answer 33

Ok.so if the area of a rectangle is L(w) , then what would 1/4 that area be?

Answer 34

idk :(

Answer 35

see how there are 4 rectangles inside 1 of them? so if the area of the BIG rectangle is L(W), then by taking the area of the smaler ones, which is also L*w, we can saw the area of 1 of those rectangles is \[(\frac{ 1}{ 4 })*L*w\]
