Homework Problems

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 ;-;

I've been crying over biology :/

Someone please help me with this! I can't seem to solve it ):

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

I'll take a try!

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

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.

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

I GOT IT! THE METHOD OF SUBSTITUTION!!!! Ok, give me a few minutes...

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

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

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

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

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.

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.

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

Ok, I think your answer would be right then...

What about 0.003 divided by 106?

Um that is... a very large number

0.0000283.

And the limiting factor is 1.

And the limiting factor is 1.

Do you have the link?"

Which math course are you taking?"

Calculus

Then wouldn't it be 0.00003?

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

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

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?

WAIT. I THINK I GOT IT.

OMGHOSH. I'M SMART.
