Question

MEDAL!!
The map shows the location of a mall, library, and school in a city:

Britney traveled from the school to the mall and then from the mall to the library. Alice traveled directly from the school to the library. How many more miles did Britney travel than Alice?
8 miles
9 miles
10 miles
12 miles-wrong

Answer 1

ooo what fun ok.. let me read the graph real quick

Answer 2

OK

Answer 3

are the two legs of the triangle , larger or smaller, than the hypotenuse

Answer 4

larger

Answer 5

School to mall, and mall to library, should be easy to add up, then use the pythagorean theorem to get the diagonal length

Answer 6

ok so first tell me how many you see alice traveled than tell me how much you see brit traveled and then you subtract.... so really all you have to know is the distance of both of them this one just adds a graph but is no different from what i stated above

Answer 7

10,10,-4

Answer 8

Brittany traveled, 10 up, then 24 left, for a total of 34

Answer 9

but now you also need alice

Answer 10

then subtract to see the difference in miles

Answer 11

Alice traveled the diagonal length

\[c = \sqrt{10^2 + 24^2} = ?\]

Answer 12

8?

Answer 13

\[c = \sqrt{100 + 276} = \sqrt{676} = 26\]

Answer 14

Alice traveled 26
Brittany traveled 34

the difference is?

Answer 15

24 ^ is not 276?

Answer 16

i calculated it

Answer 17

8

Answer 18

typo, the 26 is correct

Answer 19

the difference is 8

Answer 20

sounds, good, you know how everything was found though?

Answer 21

:}

Answer 22

no im really confused l. i have a hard time comprehending math.

Answer 23

my grade is a f

Answer 24

but how did you get 26?

Answer 25

If they are traveling straight up/down, or straight left/right on the coordinates, you can
see the distance without doing any work

Answer 26

You see how 10 and 24 is found?

Answer 27

of 24^2? so you added it ?

Answer 28

yes

Answer 29

ok, the 3 paths form a right triangle. If you have a right triangle, there is a property called pythagorean theorem. It says

(side) ^2 + (side)^2 = (Diagonal)^2

Answer 30

24^2 is 576 btw

Answer 31

that is all you need to know

Answer 32

thank you very much!

Answer 33

diagonal ^2 = 10^2 + 24^2 = 100 + 576

diagonal^2 = 676

diagonal = square root of 676 = 26

Answer 34

then they just want to know what is longer, and by how much. The diagonal, or the 2 sides added

Answer 35

very understandable!

Answer 36

this one would be 29 right?
What is the length of the unknown side of the right triangle?
21
29
400
441

Answer 37

use the picture i just posted

Answer 38

20*20 + 21*21 = x^2

Answer 39

^ this means multiply?

Answer 40

or to the power?

Answer 41

yeah * -multiply

20^2 = 20*20

you were right with the 29

Answer 42

oh ^ - power
* - multiply

Answer 43

x^2 - "x squared"

Answer 44

yay! i sorta get it! do you mind checking my answers when i complete each one?

Answer 45

sure just tag me

Answer 46

ok.
