This is ALL of the information that is given to the question.

In some codes, letters are switched with other letters. One way to break this kind of code is to examine the frequencies of the letters used in everyday language and then to compare these frequencies with the frequencies of letters used in the coded message.
The location of the letters in a word can also help you to decide which letters are vowels.

Decode the following:

What wierd thing can your body do that others can't.

It seems people are more liberal than ever, and may actually be able to accept evolution as how/why humans are here. I myself dont believe in God, and feel its something humans created to help explain everything. But as knowledge accumulates, will this ultimately become the main thinking? And I'm talking about a society much different than ours currently is. Forget education, class, races, whatever. Just envison some type of human society say 10,000 years from now.... religous people or not?

My friend was riding his bike one day and suddenly it rains and there was a lightning struck on the tree. Even scared, he stop and went to the tree which was hit by the lightning and he'd found some kind of animals tooth that mounted on the tree. Now, the question is... Why there is a tooth? Science didn't say any of this.

i'm not really good at setting up word problems...i don't need you to solve it just set up the equations in order to do so....


.....
According to Mrs. Randolph's will, each of her great-grandchildren living in Georgia received $700 more than each of her great grandchildren living in Florida. In all, $206,100 was divided between 36 great grand children. The Georgian great grandchildren decide that the will wasn't really fair, so they each contribute $175 to be divided among the Floridian great grandchildren. If all great grand children now have an equal share, how many great grandchildren live in Georgia?

i think you have to use 'system' equations to set this up...you don't have to solve it...although it'd be appreciated...but the main thing for me is pulling out the numbers (equations) from the word problem....please help me...

because if it goes on forever, then there is no scale, so there is everything and nothing., and if its still expanding, then well that just makes no sense and does not bare thinking about, for the obvious reasons! what do you all think!!

Last night I looked up at the moon, which was full, and it looked like there was clouds on the moon. What I mean is, it was a bright moon, but with grey spots on it. Does anyone know why?

w-3/8 -5-w/4 = 4w-1/8 -1



8w-24/8 - 10-2w/8 = 32w-8/8 - 1

w-24 - 10 - 2w = 32w - 8 -1

w - 2w - 32w = 14 -8 -1

-w -32w =5

31w =5

w = 5/31

Is pre-calculus/calculus really all that difficult. I have heard alot of things about it. One of my teachers once said, "You will have to take pre-cal next year, or it will take you." What's really makes it so difficult.

What is a good use for elements such as Li, K, Na, Sr, Ba, Ca, & Cu nitrates because of the colors they give off when burned?

This question is in relation to a previous question concerning the 3 terrestial elements currently being used for discussion purposes.
Matter, Dark Matter, Dark Energy. I'm interested in the relationship between the universal expansion and the 'resting place' of captured matter/energy. This has to do (in my tiny brain) with the relationship between the galaxies ability to stay compact instead of spinning off piecemeal into 'space' even though the cosmos is still expanding.
