I'll try to solve.
anonymous
  • anonymous
Will you give me a minute?
anonymous

oops error the question is easy use the pythogoread formula c^2=a^2+b^2 white dr is c westerfield is b and blue is a now we plug in. 144= blue^2 + 13^2 ^ that is already squared for you. ^ that is westerfield. Solve for blue. Do you know how?
anonymous
  • anonymous
on previous one i forgot to square the blue blvd one
anonymous
  • anonymous
Okay. Let me try to solve,alright?
anonymous
  • anonymous
ok :)
anonymous
  • anonymous
Thank you,sir.
anonymous
  • anonymous
so basically 144=a^2+13^2?
anonymous
  • anonymous
YES
anonymous
  • anonymous
Okay, ty. Let me solve for A now,then.
anonymous
  • anonymous
I got '5' as 'a^2'.
anonymous
  • anonymous
I think your diagram might be wrong tho
anonymous
  • anonymous
Really?

  • anonymous
How's it wrong?
anonymous
  • anonymous
the longest street is suppose to be the c in the theorem. white dr is sqrt (144)= 12 but westerfield is 13 which is longer.
anonymous
  • anonymous
No, that's how it is on my sheet. That's okay. i can leave it as is.
anonymous
  • anonymous
Good observation, though.
anonymous
  • anonymous
so... would it be '144=5^2+13^2'?
anonymous
  • anonymous
it is wrong either blue is longer. But for sure westerfield is longer.
anonymous
  • anonymous
5^2+13^2=194 nott 144 silly
anonymous
  • anonymous
Oh right i forgot to square it.
anonymous
  • anonymous
Sorry bout that...
anonymous
  • anonymous
wait wait wait..
anonymous
  • anonymous
how did you get 194?
anonymous
  • anonymous
you gave me 194 5^2+13^2 you gave that 25+169=194 You cant solve it until you fix the streets. You need to know the longest street. You cant just pick it. white dr =12 but wester field is 13. 13 should be c or blue but we dont even know what blue is. we can make blue c also to see if it works
anonymous
  • anonymous
Oh right....Okay.
anonymous
  • anonymous
Fine, whatever you think is best.
anonymous
  • anonymous
Let's make blue C.
anonymous
  • anonymous
make westerfield c and the numbers work better :) c^2= b^2+b^2 169=144+b^2 ^ wester field 13^2 is given so square it to get 169 ^ white 144 was given and already squared ^ blue now solve :)
anonymous
  • anonymous
Okay. So...
anonymous
  • anonymous
This might take a min or 2
anonymous
  • anonymous
solve for b
anonymous
  • anonymous
Yes,one second.
anonymous
  • anonymous
Is it 5?
anonymous
  • anonymous
yup
anonymous
  • anonymous
YESSSS!
anonymous
  • anonymous
|dw:1364431455866:dw|
anonymous
  • anonymous
I also got that the first time.
anonymous
  • anonymous
5 as the missing value, I mean.
anonymous
  • anonymous
Thank you very much for your assistance.
anonymous
  • anonymous
144 = a^2+13^2 --> a=5^2
anonymous
  • anonymous
no but it did not work out cuzz you said "so... would it be '144=5^2+13^2'?" no 5^2+13^2=25+169 is not 144 what you were actually getting was imaginary result. a 5i. what you did was something like this 144=a^2 +13^2 simplifies to 144=a^2+169 then you subtract 169 from both sides 144-169=a^2 -25=a^2 then you try to take sqrt of -25 but how? you cant take sqrt of negatives. you can but it is out of your scope. Unless they taught you about imaginaries already.
anonymous
  • anonymous
no....
anonymous
  • anonymous
That was a long reply. LOL.
anonymous
  • anonymous
Thanks anyhow. So the final equation would be 169=144+b^2 --> b=5?
anonymous
  • anonymous
@timo86m help please
anonymous
  • anonymous
Yes now you just add up the lengths of the streets to see which is longer route.
anonymous
  • anonymous
Okay....
anonymous
  • anonymous
westerfield and blue =13+5 = 18 blue to white=5+12=17
anonymous
  • anonymous
there is a one mile difference.
anonymous
  • anonymous
yup :D lol you got ahead of me :) But anyhoo i think this is best.
anonymous
  • anonymous
Nope, you're way ahead of me.
anonymous
  • anonymous
I just did first grade subtraction.
anonymous
  • anonymous
So, how would you state the answer?
anonymous
  • anonymous
joe will run one mile further along his new route
anonymous
  • anonymous
ok.thanks!
