I think I found a dimond in my backyard cause I live by the mountains and I hit it with a hammer against the concrete with all of my force ( and I can lift 300 pounds) and it only broke a little bit .

I know that the easiest way to tell someone how to distinguish monkeys from apes is to tell them that monkeys have tails and apes don't, but I know there are some species of monkeys that don't have a tail either and I would like to know which ones they are, thanks.

I presume the arguement is based on the fact that the Universe is infinite but it seems hard to believe to me

I watching a show about black holes the other day, it said that nothing can escape a black hole not even light. Well what is light, how would you describe it.
Also
I would like to know different theories on how the universe formed or whatever you want call this thing we are floating around in.
Anythings possible or does everything happen for a reason?
All answers welcome even if your a little bit crazy :)

I vaguely remember something about not using The Law of Sines in conjunction with basic trig. For instance, if I have a polygon that I split up into triangles, and I use The Law of Sines to find a side that happens to be the hypotenuse of a right triangle (as in a non-right-triangle that shares a side with the hypotenuse of a right-triangle), will there be an error if I use basic trig to find the other angles, sides, etc. in the right triangle?

Am I just making this up in my head?

Sorry if this sounds confusing...

You only have one piece of paper (11 inches by 8 1/2 inches). No tape, staples, etc. It has to support itself. You can't support it on it ends (e.g. Have it tied to bigger pieces of paper.

It involves vibrio ficheri and buioluminescence!! so vibrio fischeri is a bacteria that produces light, which is called bioluminescence. Can anyone help me think of a project envolving this??? THANK YOU!!!

I wish to keep the surface area of the remaining ice cream at a minimum to keep it fresh and keep it from getting gummy. I believe the worst method would be to shave a sliver off the top every time. What method would be the best?

Okay, I know that it's using the cofunction identities and the even/odd identities, but other than that, I'm at a loss. Any help would be GREATLY appreciated and as always, I'll pick a best answer TODAY!

Find the exact value of cos (α + ß) if sin α = 3/5 and sin ß = 5/13, with α in Quadrant II and ß in Quadrant I.

Now I know that that means that the cos of α will be negative and the cos of ß will be positive, and I also know that this involves the cofunction identities somehow, but it's acting for the EXACT value, so I can't use the inverse of the sin values of α and ß. So how would I go about solving this? Thank you so much!!!

P.S. What kind of class (i.e. what year in high school math) would you find this in????
