How come if you ask a question some snobby punk thinks is ridiculous, he answers with the year? Like "That's ridiculous. It's 2007." What the hell does the year have to do with anything? Do you think people in the past were like "what a stupid idea.It's 1443, for pete's sake." Other then the fact that they didn't say "for pete's sake" back the, I think this is a valid question.

I'm not a math person and couldn't figure out how to answer this question even if you explained it to me. (I've asked this question before and got a lot of detailed answers about how to solve the problem, but I'm looking for a solution to a real-world problem and just need the answer itself.)

I have a regular hexagon that is 12 feet across (side to side, not point to point).

How many many square feet are contained in that hexagon?

Okay, this has always been bothering me, because whoever I ask I get mixed responses.
Lets suppose you're in an elevator thats free falling from a the
(x) floor. Right before impact, if you were able to jump and get yourself suspended in air, will you avoid getting hurt? Or would you take damage once you land again?

I'm no physics expert nor have I ever really taken a course in physics (-.-) but someone told me about how the velocity at which the elevator is falling is proportional to yours and in order to actually get yourself suspended in air you have to jump at that same velocity or greater. My question here is, is that true?

Today we rented a pontoon boat and saw lots of wild Dolohins. Well, of course we fed them when they came up to our boat. Later we found out that you can be charged up to 10,000 dollars for feeding the dolphins. Should I be concerned?
