I got 4.17 sq ft by dividing 10 by 12 ( 12 inches in a foot) then i found the total surface area of a cube by using .833 as the length of a side.

Nearly any time I see a dead insect it's on it's back with it's feet sticking up. Like a potato bug. How and why do they end up like that?

for having an idea....
a black hole has a surface which must not necessarily be the same as the diameter of its event horizon.
This is (as far as i know) depending on the BH size and should make it possible for certain types of BH to have some Space between EH and surface.

So ok we can't observe the surface...
what will happen if this surface get heated up, lets say by infalling matter in hughe ammounts (neutron star or bigger).
Is it heating up ? will it do so ?
or not ?
and if so CAN it heat up endlessly ?

well, if you took geometry you know the symbold for when it says measurment angle. so here's the equation that I need to solve for X. measurment angle1=2x-8,measurment angle 3=116

Every month jane plans to add $1 to her account.

Arthur plans to add $3 to his account every month.

If they each start with $10, when will Arthur have three times as much as Jane ?

Find the slope and y-intercept of y=-3/5x-2?
Find the slope and y-intercept of y=-3/5x-2
This is negative three fifths minus two

I can't understand the concept of finding the slope and the y intercept, can someone explain it to me? I would greatly greatly appreciate it. This is my weakest part in math, and I'm lost and our reading doesn't do mush for us.

..without jumping in, of course...

this is one of the questions where i'm not that sure..
is there any mathematical proof ?
I know there are some alternative ideas, but i heard it was shown that there must be a singularity

So can someone please be so kind and shed some light onto this ? ;)

yes, ok i know what a black hole is
i think i know alot about them, but i can't get rid of the idea that there must be some kind of scenario which could lead to the destruction of such a thingy.

-scenario's of (exotic) matter falling into
-highspeed merging with other holes
-vibration caused by infalling matter (maybe exotic matter)

is there anything like that imaginable ? what do you think ?
i hope to get a few very weird ideas here ;)

The difference amazes me. Once you cross the state line in Florida there's a difference. I thought it was all the Gulf of Mexico. I would think some of the water mix together and the difference would be gradual.

I'm not talking about how tall was she in the painting when she was sitting down, but what I am asking is what was her height standing up, and what is there in the painting that you would base your guess on? I have a math theory based on measurments in the painting , and some other things, and I'll give my own guess at the end of the thread.

From an evolutionary perspective, there is nothing reproductive about the butt, but people see it as erotic. Why? Also, why do people want anal and oral sex? There's no reproductive value in having sex in these ways. Millions of years ago, it took mother nature a huge incentive to get animals to want to reproduce. That's where the orgasm came in. However, some human sexual behavior doesn't make sense.
