Does anyone have them right now? How do you get rid of them? They are grossing me out. They end up in our drinks and I don't even want to eat at home. Do they bite? We don't have any food out that they would be attracted to. I don't know where they are coming from. I live in a really nice apt complex. I wonder if I should call them to take care of the problem- what do you think of that?

at school we are learning about oil, gas electricty solar energy and so on.
i understand oil was made millions of years ago by dead organisims and trees
and today where runing out . well not runing out by oil doesnt last forever
so i asked my teacher if oil is made by heat and pressure then since today is so modifyed with technology why cant we artifically make oil?
why cant we get funding to compresse and heat dead things and non recyclable garbage? why cant we?
i mean not take million of years but make oil to last a year. rather than taking it from the ground everyday?
why doesnt everyone use solar power, if we know the effects it has on the earth why are people still using it. i mean global warming has been around for years why hasnt there been change yet?. theres change but its slow.
someone out there care to explain to me.
please?

I always see the words "majority" "large segment", "predominant", "sizeable" in many articles but not know how many the word "sizeable" is in concrete number. I think this is totally judged by feeling. According to my feeling, "majority" may be more than 80%. "predominant", I'm not sure. "large segment" I'm not sure but may be more than 70% according to my feeling. " sizeable" may be about 5-20% but of course not more than 20%. What's your opinion? Can u tell me what CONCRETE precentage of these words (MAJORITY, LARGE SEGMENT, PREDOMINENT, SIZEABLE) are in CONCRETE number according to your FEELING?

Find the approximate value of pi by circumscribing a regulare heagon (n=6) about a unite circle and then doubling the number of sides four times until you reach n=96.



note: for the regular hexagon, S(6)=(2sqrt(3))/3
note: this is based on the forumlas s(2n)=(sqrt(2-sqrt(4-(s(n))^2))) and s(2n)=(2sqrt(4+(s(n))^2)-4)/s(n) for the side of a regular 2n-gon inscribed in and circumscribed about a unit circle, respectively.


this was a hint given but i still don't know: find s(n) in each case, then multiply by n and divide by 2. Starting with n=12, the expressions will get increasingly messy, so it is enough to find the decimal value in each case.

PLEASE HELP ASAP..thank you so much
