Answer 2

please help I'm trying to explain this to my brother (how to solve it) but Idk how,

Answer 3

Answer 4

hello? I need help now

Answer 5

the shpe contains

1 trinagle 1 rectangle

the area formulae are

Area of a triangle

\[A = \frac{1}{2} \times base \times height\]

Area of a rectangle

\[Area = length \times width\]

the area of the combined shape = Area of Trinagle + area of the rectangle

dimensions length = base = 11 1/5
width = 8 4/5

triangle height = 6 2/5

substitute the values for the correct answer.

Answer 6

could you help with a few more?? you're such a great help!

Answer 12

I need to explain the questions to my brother.

Answer 13

campbell covered the first but I have a few more

Answer 14

I will fan you all and start new posts to be able to medal you all if you explain it to me so I can read it to my brother.

Answer 15

H is the correct answer.

Answer 16

I need it explained...

Answer 17

He needs to understand it

Answer 18

Basically the formula for a triangle is 1/2 base times height. The formula for a rectangle/square is length times length. To find the area you ADD the area of the triangle and rectangle.

Answer 19

For number 3 you remember that an area of a triangle is 1/2(base*height) right?

Answer 20

yes

Answer 21

97.5 = 1/2(base*height)
97.5 = 1/2(13)(base)
(2)97.5 = 1/2(13)(base)(2)
195 = 13 (base)
195/13 = 13/13 (base)
base = ?

Answer 22

why do you multilply a 2 next to the base on the 3rd line

Answer 23

You multiply two to get rid of 1/2 because 1/2 times 2 equals 1

Answer 24

oh ok

Answer 25

can you help me with the other picture?

Answer 26

Yes but you do know the answer to number 3 right?

Answer 27

I'll figure it out and check with you but could you start on the next one? I'm kinda in a hurry
:)

Answer 28

Sure, well to get number 4 you just need to use the area of a parallelogram formula. So base times height.

What does 24 * 9.75 = ?

Answer 29

234

Answer 30

So what the student correct?

Answer 31

idk gimme a sec he's still going

Answer 32

how do you explain to a kid how to get rid of a fraction in an equation? (like when you multiplied 2)

Answer 33

You get rid of a fraction when you know the end answer.

Example = 5 = x(1/2)

You know the end answer is 5 but you want to know what x is. So you have to get rid of 1/2 . To do that it needs to equal one. So (1/2) time 2 = 1. But you have to make sure that you times it on both sides.

5*2 = x(1/2)*2

10 = x.

Answer 34

got it. thanks!

Answer 35

No prob. Is that all you need or do you need more help? :)

Answer 36

I would love some more!!

Answer 37

Ok just tell me :)

Answer 38

okay give me a second to type it out

Answer 39

ok :3

Answer 40

oh wait on number 4

Answer 41

I still don't get it. Can you explain it step by step?

Answer 42

Ok :)
Well what is the base of the figure in the question?

Answer 43

I forgot about the little triangle and solved the area for the rectangle thingy and now I have 234 but I'm confused as to what the answer would be

Answer 44

actually he is gonna ask my dad nvm can you help me with another?

Answer 45

Well with that we can x out H and F. But it's asking HOW we got the answer. Real quickly tell me the formula for the area of a parallelogram.

Answer 46

L TIMES W

Answer 47

Sure I can help ya.

Answer 48

i'm sorry but I'm still so confused and we don't have much time. if you want we can save that question for the end but I need to move one

Answer 49

Do you want the answer?

Answer 50

A square with a side length of 30 cm is divided into 4 triangles. Which expression CANNOT be used to find the area of one of the four small triangles?
a. 30^2 divided by 4
b. 1/2(30*15)
c. (30*30)divided by 2
d. 450/2

Answer 51

No because he needs to understand it AND show work

Answer 52

Ok well For this one what is the area of the square?

Answer 53

900

Answer 54

Good, what does 900/4 = ?

Answer 55

225

Answer 56

Good so now we know the area of the triangles.

Does (30 times 30) divided by 2 equal 225?

(30 *30)/2 = ?

Answer 57

no

Answer 58

450

Answer 59

So that means that you can NOT solve the answer using (30*30)divided by 2. So the correct answer is C.

Answer 60

no its d

Answer 61

because 450/2 has absolutely nothing to do with the question at all

Answer 62

Why is it d?

Answer 63

Good answer

Answer 64

am I right or is it wrong?

Answer 65

or is 450 somehow in this?

Answer 66

Well I would go with c because it is the ONLY answer that does NOT equal 225.

Answer 67

hmm.. ok.

Answer 68

Anyway I have to go. <:3

Answer 69

but wait since c=450 it does have something involved!
