My astronomy teacher gave us an assignment to find a good time to observe the phases of the moon. We have from 11/20 until 12/4 to do this project and I think I picked a time after the moon already set.... meaning I won't be able to observe it. So could someone give me a right time to observe the moon between yesterday and december 4th? I picked 6:30PM initially. I know today was a new moon and I wouldn't be able to see it anyway but when the moon actually appears lit up, will I have the right time to observe it at? (The moon must be observed at ONE time for the entire 2 weeks of its waxing.) If not, someone give me the right time please.

The owner of a carousel wants to paint the surface of its floor. The paint is very expensive, so he only wants to buy the exact amount needed. He sends his younger son over to measure the the surface area of the carrousel. When the son gets there, he realizes that he cannot measure the exact diameter, because all of the machinery is in the middle of the hole. So, he takes a measurement and leaves. When he arrives at home, he tells his father that he measured 70 feet from one outer edge to the the other side, and the tape measure touched the opening in the center.

His father was furious! How could he be so incompetent?! But his older son soon spoke up: "Father, I know the area of the floor of the carrousel." His father was amazed.

What is the area of the floor of the carrousel? (Show your work :-)

I watched a movie that other day where this guy got scalped in this movie and was woundering if like a piece of bone was taken off the top of the skull exposing the brain, would your brain even be able to function, or would you not live long? See I don't know what would happen.
