Julie is looking at a treasure map. The map is marked in paces. She is standing by the merry-go-round. How many paces will it be for her to go directly to the bridge? about 20 paces about 4.5 paces about 6 paces about 12 paces

OpenStudy (melody323):

Which of the following figures does not have line symmetry? H D R A

OpenStudy (mathwizzard3):

which one is the merry go round?

OpenStudy (melody323):

The circle with the brown lines on it by the river

OpenStudy (mathwizzard3):

Oh okay :)

OpenStudy (mathwizzard3):

Why don't we use the distance formula again!

OpenStudy (melody323):

I was thinking 4.5 paces but I don't know how to do this

OpenStudy (melody323):

ok

OpenStudy (mathwizzard3):

Lets treat this like a regular graph with the x and y axis. What is the point for the MGR and for the Bridge?

OpenStudy (mathwizzard3):

MGR=merry-go-round

OpenStudy (melody323):

2,3 for the MGR

OpenStudy (mathwizzard3):

why do you think it would be 2,3?

OpenStudy (mathwizzard3):

I would say 9,7

OpenStudy (melody323):

ok

OpenStudy (mathwizzard3):

while for the bridge about 5,6

OpenStudy (melody323):

I don't know what I'm doing

OpenStudy (melody323):

ok

OpenStudy (mathwizzard3):

It's fine :P Half of the time that is me xD

OpenStudy (melody323):

whats the equation

OpenStudy (mathwizzard3):

d= sqaure root of (9-5)^2+ (7-6)^2

OpenStudy (melody323):

hold on

OpenStudy (mathwizzard3):

what is it?

OpenStudy (melody323):

i think i did it wrong

OpenStudy (melody323):

(9-5) ^2 + ( 7-6)^2 4^2 + 1^2 8 + 2 equals 16 This is what I got

OpenStudy (mathwizzard3):

You messed up when you said 4^2 = 8 and 1^2 = 2

OpenStudy (mathwizzard3):

4^2 is actually 4 times 4

OpenStudy (mathwizzard3):

and 1^2 is actually 1 times 1

OpenStudy (mathwizzard3):

so it should be 16 + 1

OpenStudy (melody323):

so it would 16 + 1

OpenStudy (melody323):

but 17 isn't an answer

OpenStudy (mathwizzard3):

remember that everthing is in the \[\sqrt{everything}\]

OpenStudy (mathwizzard3):

so it is the square root of 17

OpenStudy (mathwizzard3):

which is about 4.1

OpenStudy (mathwizzard3):

but since we had to estimate a little it was a liitle off so it is B

OpenStudy (melody323):

So 4.5

OpenStudy (mathwizzard3):

Yup!

OpenStudy (melody323):

What about the symmetry question with the letters

OpenStudy (mathwizzard3):

Where are the figures, I need a picture

OpenStudy (melody323):

it won't let me put it up

OpenStudy (mathwizzard3):

Oh, well maybe if you read this https://learner.org/courses/learningmath/geometry/session7/part_a/index.html

OpenStudy (mathwizzard3):

Yeah I can't see the picture

OpenStudy (melody323):

All the letters that I posted look similar to this one

OpenStudy (mathwizzard3):

Wait so your just talking about letters

OpenStudy (mathwizzard3):

please just look at the examples on that link I gave you and then tell me what you think it is

OpenStudy (melody323):

ya

OpenStudy (mathwizzard3):

Now which letter do you think doesn't work?

OpenStudy (melody323):

D or R

OpenStudy (melody323):

I was thinking R

OpenStudy (mathwizzard3):

|dw:1460756256912:dw|
