Let's assume 50% is female. Can someone work out the formula? We used to have rats, and used to think of this question, but never had it solved. From college math, I believe you use 10 to the power of something... arggh... my math has become so dull

It often amazes me how many people want carpeting in their dwelling area, you often see "new carpeting" advertised as if this is a desirable quality to have in your indoor space. First of all there is the carpet, a slew of toxic materials(xylene, toluene), plastics, fire-retardants, dyes, pesticides, etc...then you have this toxic mass applied to your floor with equally toxic volatile glue. Most of these compounds are highly volatile, i.e they turn to gas readily and hence once they are in an enclosed space you will inhale them for years post carpet application. Is it any wonder why people complain of fatigue, irritability, mood disorders, allergies when we have a substance that is so biologically toxic in our living environment? It is an indisputable fact that these chemicals cause deficits in health including cancer yet I guess having that carpet is more important then you and your families health. So the question is, why do people even WANT carpet at all in their dwellings?

Factual and supported answers preferred.

Aside from the routine, at the risk of sanity and credibility, are there any Nephilim or similar stored at the Smithsonian vaults ?

I am looking for a vendor that sells a glass (or glass coating) that can be switched between being reflective and transmissive. I am not looking for just privacy glass, it needs to be reflective in one state. Any suggestions?

My question is basically..... how hard is it? What extra material do they teach you that they don't teach in a regulars course. I like math a lot and thats why I'm asking. Also do you learn a little of Trig. or calculus in algebra 2 or do you have to wait till pre cal to be introduced?

Im curious how many people who post answers on the math section have had any post secondary math education. Some people have very bright and insightful answers, but some show true ignorance.

Here is the question

The eyepeice of a compound light microscope has a magnification of 10x and the low-power objective and high-power objective lenses have magnifications of 10x and 30x,respectively. If the diameter of the low-power field measures 1500 micrometers, the diameter of the high-power field will measure either 4500 micrometers or 500 micrometers. Select the correct diameter and explain your answer

how do you show a girl, you're in command and listen to her needs at the same time. how do you be romantic. if she likes you, should you be bothered about, whevever or not she's taken. should you, hold your own, when you know your right. when she does something wrong, like not calling you when she said she would. do women like the unexpected. if you feel you need time, should you tell her and work on building from the friendship. does being a friend with a girl, mean you can have sex with her. i don't really want women to think of me that way.
