OpenStudy (anonymous):

OpenStudy (saifoo.khan):

OpenStudy (saifoo.khan):

OpenStudy (anonymous):

I like your array of sites opened up above the picture :) You know it's bad when even facebook can't help.

OpenStudy (anonymous):

i mean, i need to do the working, with paper and stuff compared to your other questions i just did by looking at it and thinking about it.

OpenStudy (saifoo.khan):

lol, Facebook sucks now.. Join GOOGLE+

OpenStudy (anonymous):

could you graph it? I think that the speeds would be slope and maybe the times ore y intercept?

OpenStudy (saifoo.khan):

idk, i need the answer.

OpenStudy (anonymous):

I meant are. Not the metal

myininaya (myininaya):

ok i will look at this in a few minutes

OpenStudy (saifoo.khan):

:(

OpenStudy (anonymous):

is it 8:25 pm? or does that sound too ridiculous? my reasoning was "train B is half an hour behind, that means its 42 miles behind (84/2) and will only gain on train A at 4 miles per hour so 42/4 = 10.5hrs so 9:55 plus 10.5 hrs is 8:25pm right?

OpenStudy (anonymous):

That's farther than I got.

OpenStudy (anonymous):

farther into the problem, I mean

OpenStudy (saifoo.khan):

So??

OpenStudy (anonymous):

thtas my answer, but im not sure until someone agrees or disagrees with an explanation

OpenStudy (saifoo.khan):

Wait for muinin

OpenStudy (saifoo.khan):

myinin*

OpenStudy (anonymous):

indeed.

OpenStudy (anonymous):

I'm going to go bug my brother; he likes math.

OpenStudy (saifoo.khan):

Lol.

OpenStudy (anonymous):

He said to go away.

OpenStudy (anonymous):

:(

OpenStudy (saifoo.khan):

):

myininaya (myininaya):

they will meet 14 hours after 9:25

OpenStudy (saifoo.khan):

wow! u r backkk!

OpenStudy (saifoo.khan):

so whts the final answer? wht should i type?

myininaya (myininaya):

14 hours + 9:25am=23:25 army time=23.25-12=11:25 pm

OpenStudy (anonymous):

yeah but why? im inclined to believe you with all those veteran medals but can you explain what i didnt do please?

myininaya (myininaya):

i will post ok give me just a sec so i can write neat

OpenStudy (saifoo.khan):

like this?

myininaya (myininaya):

yes

OpenStudy (saifoo.khan):

THnks ALOT.

myininaya (myininaya):

OpenStudy (anonymous):

myininaya- just one more time, could you walk me through it? I still don't quite get what you did.

OpenStudy (saifoo.khan):

Lol.

myininaya (myininaya):

give me a sec

OpenStudy (saifoo.khan):

1 sec up!

myininaya (myininaya):

i was looking at something else now what is the question

OpenStudy (saifoo.khan):

i posted.

OpenStudy (saifoo.khan):

Mine?

myininaya (myininaya):

let time 0 represent 1991 so time 4 represents times 1995 at time 0, we have 69.5 at time 4, we have 72.2 the slope is (72.2-69.5)/(4-0)=27/40 so linear equation is of the form y=mx+b we know m=27/40 y=27/40*x+b we also know a point on the line (0,69.5) 69.5=27/40*0+b 69.5=b so the equation is y=27/40*x+69.5 ------------------

OpenStudy (saifoo.khan):

myinin

OpenStudy (saifoo.khan):

wht the hell. u r simply Great. :D

OpenStudy (anonymous):

can you do that for the original q?

myininaya (myininaya):

what?

myininaya (myininaya):

do you need me to plug in 13? lol

OpenStudy (saifoo.khan):

0.675 to the nearest tenth?

myininaya (myininaya):

0.7

OpenStudy (saifoo.khan):

ok, so i will plug 13 into 0.7(13) +.... right?

myininaya (myininaya):

is this really you khan?

OpenStudy (saifoo.khan):

im his brother.

myininaya (myininaya):

oh

OpenStudy (saifoo.khan):

so is this right?

myininaya (myininaya):

just plug into the equation i gave you

OpenStudy (saifoo.khan):

He is just comming.

OpenStudy (saifoo.khan):

y not in 0.7?

myininaya (myininaya):

yes u should round to nearest 10th like it requests

OpenStudy (saifoo.khan):

Here?

myininaya (myininaya):

yes

OpenStudy (saifoo.khan):

i hate myself im not good at maths.

myininaya (myininaya):

hey i made a mistake for some reason i divided 840 by 60 instead of 80 so it would have been 10.5 hours later like paul said gj paul

OpenStudy (saifoo.khan):

Lol, then that must have gone wrong!

OpenStudy (anonymous):

bah, screw chat for a while.... whats the question then?

OpenStudy (saifoo.khan):

what is the final answer?

OpenStudy (anonymous):

OpenStudy (saifoo.khan):

this trains one!

OpenStudy (anonymous):

n 10.5 hours later like paul said gj paul

OpenStudy (saifoo.khan):

Final answer?

OpenStudy (anonymous):

yeah

OpenStudy (saifoo.khan):

am pm?

OpenStudy (anonymous):

pm

OpenStudy (saifoo.khan):

10 05 pm?

OpenStudy (saifoo.khan):

sorry, im a bit confused!

OpenStudy (anonymous):

wasn't it 10:25 pm?

OpenStudy (saifoo.khan):

lol, idk.

OpenStudy (saifoo.khan):

just give me the final answer man!

OpenStudy (anonymous):

train B is half an hour behind, that means its 42 miles behind (84/2) and will only gain on train A at 4 miles per hour so 42/4 = 10.5hrs so 9:55 plus 10.5 hrs is 8:25pm right?

OpenStudy (saifoo.khan):

Oh, so 8:25 pm is the final answer?

OpenStudy (anonymous):

so yes, not ten pm 8:25 pm

OpenStudy (saifoo.khan):

Thnks man!
