A car is travelling East at a horizontal speed of 56.3km/h and rain is falling vertically with respect to Earth. The traces of rain on the side windows of the car make an angle of 65 degrees with the vertical. How would I find the magnitude and the velocity of the rain with respect to the car.

any catch that interview where keith said that paris hiltons psychiatrist doctor was a "FRAUD" and a fake doctor (the guy was an osteopathic physician)?

keith olbermann is the biggest hack in news for that statement. DOs are fully licensed physicians in all fields of medicine, can prescribe medicines, perform surgeries and have the same capabilities of any "MD"

I don't understand how you remove the X's in a sum...
19+8+13+x+13-x+28-x+8-x=77
89-2x = 77
-2x = 77-89
-2x = -12
x = 6

how did you get the 2x?

and this one:

10+x+15-x+13+x+10-x+12-x+28+x =93
how do you solve this.

thanks.

The Bible says (about spiritual gifts)" What you receive as a gift, give as a gift." If they have a "gift"..they did nothing to earn it. So shouldn't they share this "gift" freely?

6|x+4| = 8|x-2|

7|x+4| = 8|x-2|

2|x-6| + 8 = 4|x+2|-10

All women in the world had their hymen torn before they ever gave birth to their first child. All the women in the world, without a single exception, were born to mothers who no longer have their hymen. Yet, we never heard of a mutation caused by womens' loss of their hymen. We never heard of a new "strain" of women who are born without a hymen. Single rare and random cases - yes. But, as a permanent mutation - no.

If "evolution" is right, this change in the body started "millions of years ago", ever since the first woman appeared in the world. For animals with hymens, this change started even earlier than for humans. So, why didn't females "evolve" into females without hymens?

Isn't that sufficient and convincing factual evidence to prove that "evolution theories" are nonsense?
