It's been two days and I had homework yesterday AND today wtf

message 3: by [deleted user] (new)

Kind of homework, kind of school work. I got paired with a group of complete IDIOTS for our science lab today. I told them over and over and over again what they were doing wrong and why they were wrong, but since it was 3 to 1, they turned in a lab full of wrong answers :P.

Crying over number 15 because the fricking answer is 3 but ALGEBRA CLASS WANTS THE F-CKING FORMULA AND I CAN'T DO IT ;-;

Not the beginners, really, once you get the hang of it.

I'll take a try!

message 13: by [deleted user] (new)

Oh, it's one of those two variables in one problems :P Bleh! My algebra's a little rusty, but give me a few minutes to google the process!

Thank you

message 15: by [deleted user] (new)

Ok, Google was not helpful, but I think I can get this...

Ok, isolate the two variables. But the X's on one side of the equal sign, and the Y's on the other. That'll set them equal to each other. If you break that into two equations (I.e. x blah blah blah = and y blah blah blah=) then you should be able to figure it out.

message 16: by (new)

Hm... What grade are you in? Just wondering...

message 17: by (new)

You could try setting everything equal to the y^2 and then just square root it. So set y^2 by itself on one side with all other numbers on the other side. Then square root the y^2 and the numbers and values on the other side to get y= __________.

I'm going to be a senior.

Um, I tried all of your suggestions, but they didn't work out. Do you think you could work it out on paper and show me? Dx

message 19: by (new)

Oh wow... No wonder I couldn't do it ;)

How do I upload it onto here?!

I just posted a picture of how I would solve for y. It's right above your post.

message 24: by [deleted user] (new)

Let me try...

Oh you can't see the picture?

message 29: by [deleted user] (new)

Ok, nevermind, that's what you do with two equations... ok, I'm lost.

message 30: by [deleted user] (new)

Do any of you guys get significant figures????????

message 31: by [deleted user] (new)

I think so! I aced it last year, but I might need a refresher...

message 32: by [deleted user] (new)

Ok, do any of you understand the molecular structure of carbohydrates?

message 33: by [deleted user] (new)

Okay, so basically, here's how my question goes:

0.059 x 6.95

0.059 is the limiting factor because it has 2 sig figs.

The product of the problem is 0.41005.

Convert 0.41005 to the number of sig figs in the limiting factor.

0.41.

message 34: by [deleted user] (new)

... Ok, is this math or science? I've only used sig figs in science.

I did find this, if this helps.

message 36: by [deleted user] (new)

Science.

message 37: by [deleted user] (new)

message 38: by [deleted user] (new)

What about 0.003 divided by 106?

message 39: by [deleted user] (new)

Um that is... a very large number

message 40: by [deleted user] (new)

0.0000283.

And the limiting factor is 1.

Calculus

message 42: by [deleted user] (new)

Then wouldn't it be 0.00003?

message 43: by [deleted user] (new)

3 times 10 to the negative fifth power, I think... I'm not sure... ugh, I have a huge headache...

message 44: by [deleted user] (new)

... I am so confused...

message 45: by [deleted user] (new)

Fifty frigging problems of this and I'm literally cracking. I just can't.

message 46: by [deleted user] (new)

Dude, me too. I'm working on Algebra 2, and then I've got some Biology to do. The problem is, this is all make up work and I wasn't there for the lesson, so I have no idea what I'm doing!

How about you go in tomorrow and tell your teachers you need help?

message 48: by [deleted user] (new)

WAIT. I THINK I GOT IT.

OMGHOSH. I'M SMART.

message 49: by [deleted user] (new)

:D

message 50: by (new)

I found the answer to my problem as well! Thanks for the help, though (: I appreciate it
