For example, wouldn't 10 / 0 be zero because you are dividing 10 into zero groups?
OR, would 10 / 0 be 10 because 10 isn't being divided up?

Why is the January 1st at this time of a year
chosen as the beginning of the new year rather than any other day during the one-year cycle, e.g. the winter solstice? The shortest day or the longest day.

I have a small round cut and thought it might be a sapphire, but I didn't know if there was another type out there with this coloring?

Are they the same, or what? My Biology textbook uses both of them without going into detail about the difference and I'm REALLY confused!

So regarding the idea that the universe is set up like a doughnut, where if you go long enough in one direction, that you'll end up in the same place again. How would that work? Would there be an infinite number of giant interconnected doughnuts to make up space?

Would this be a spherical plane (I'm sure that this isn't the right terminology, but I forgot what it's called. like the plane over the earth...) in three dimensions? I've heard before that the universe can't be a Euclidian space, so does that mean that it has to be parabolic or the sphere one? or is there another kind of plane that I don't know about?

Sorry that's a lot of questions in one.

My friend told me about this experiment. Where they took mice and put some in a very crowded cage. And then put the same amount in a bigger less crowded cage. And he said over time as the populations got bigger. The mice in the smaller cage began to become gay. And the mice in a bigger cage had only a few occurences of gay mice overtime. If this is true tehn mothernature would have a role in gayness. Is this a true story i need proof to beleive such an astonishing project. I dont beleive its true at the moment because if it was then this would change everyone's views on gay's and would most likely be very controversial so i would of heard about it before. Im as desperate to cling to this but need proof that is was a real experiment and if it isn't then am totally going to do it for a science fair haha.

i have a trapezoid and the base1 is 10cm, base2 is 24 cm, the left side connecting the two bases is 13 cm and the right side is 15 cm. but i dont have the height...so i dont know how to find the area!!

(the trapezoid can be broken into a right triangle and a parralelgram, the side that i sed was 15 cm is the hypotnuse of the right triangle)

please help me asap....i have no idea how to do it without the height!!

My friend says light acts like a wave. I say light acts like a particle. Who's right? There is a pumpkin patch tour riding on this.
