Do parallelograms exist in neutral geometry?
Proof?

I know they do... not sure how to prove it.

I know that wieght = mass * gravity , but I don't think that is what is going on here.

Is it that we are using the pound-mass (lbm), when we say pound?

What is going on, I've always been confused about our system?

See The cat's question:

http://answers.yahoo.com/question/index;_ylt=ApZo01JFGON920IYeGRPJUHsy6IX;_ylv=3?qid=20071213163311AAyMl2Z&show=7#profile-info-AA12298210

Assuming that Earth is 8,000 miles in diameter and rotates 24 hours a day, and disregarding gravity, if Bart skates frictionlessly from the north pole to the equation via a straight tunnel, how fast will he be going by the time he exits the tunnel? Acceleration will be due to centrifugal force of the spinning Earth, and you may simplify the problem by also disregarding coriolis forces outside of the plane of the tunnel and center of the earth.

6. x = y + 7
y = 8 + 2x

(1 point)


When submitting an answer in the form of a fraction, use a forward slash (/) to separate the numerator and denominator. For example, one half would be written as 1/2.


Note: your teacher will review your response to ensure you receive proper credit for your answer.

7. 3x + 4y = 12
y = -2x + 10

(1 point)


8. 4x + 9y = 24
y = -x + 2

OK, we all heard about how we are getting ripped off at the pump because when its hot out we get less gass than what it says on the meter due to expansion. Doesn't the opposite also hold true that we get more gas when its freezing cold out (like right now!)?????

Even most scientists are confused about this question today.

These are proofs of flat earth theory and creationism..
http://www.alaska.net/~clund/e_djublonskopf/FlatWhyFlat.htm
http://www.theflatearthsociety.org

Enter the Flat Earth Society. For over five hundred years humanity has believed the "round Earth" teachings of Efimovich and his followers.

But all hope is not lost. For through all that time, a small but diligent band of individuals have preserved the knowledge of our planet's true shape. And now, after centuries in the Dark Ages, we believe that mankind as a whole is once again ready to embrace the truth that has forever been the Flat Earth Society.

Using whatever means are deemed necessary and relying heavily on a callous disregard for the lives and well-being of our members, we have slowly but steadily been spreading the news.

entrance of the Hall building between 7pm and 8pm. Independently, each of them will equally likely show up at any time between 7pm and 8pm. Both have the same policy to wait for only 15 minutes and leave if the other party does not show up within the 15 minutes. What is the probability they will miss each other?
