TYPE OF QUESTION: Math
YOUR QUESTION: If there's an area that's 10,000 x 10,000 feet on the surface, and 100 feet deep (so, the total volume of that would be calculated in cubic feet), how many tons would that be (volume, not weight)? I'm trying to calculate that because I need to know how much it would cost to mine an area that big for an assignment. I'm not really sure how to go about it (I'm tired and not thinking straight right now, lol).

Pretty simple - volume = depth x width x length Make sure it's all in the same unit and then the answer is 1x10^10 ft^2.

Weight - Tons isn't a measure of volume...?
That depends of what is in that area - with water one square cm weighs one gram* so 1000cm^2 = 1kg, etc...I'm sure there's a way to work it out in imperial - but I never need to use it, and I don't know the US' imperial system anyway. If it's 'earth' then it depends on the density of the rock in that area. (I assume they are using real life geography as that would be a right pain to work out where I live.)

*This is the basis of the metric system...more or less. They are hopefully trying to redefine a kilogram so it's not based on a physical weight because at the moment, all their standard kilograms keep changing weight/mass!

Thanks for the reply, but I got it a few days ago. <3 Forgot to edit my post, oops. I found that 18 cubic feet equals a ton (as a measure of volume, not weight).

So sorry I haven't been active, I really don't have so much time for this. xc you can remove me, so sorry!

YOUR QUESTION:so I'm supposed to be turning percentages into angles. (The angles then go into a circle graph)

how do I do this???

Turning percentages into angles? I'm not sure. I feel like that's something your teacher should have gone over in detail. . .maybe ask him/her for help tomorrow?

do you mean like a pie graph? I didn't quite understand the question.

Yeah, where you draw a circle, and then fill in sections

Let's say this is your data:
Apples -- 20/50 -- 40%
Oranges -- 10/50 -- 20%
Grapefruit -- 7/50 -- 14%
Peaches -- 13/50 -- 26%
I know, this is lame data I thought of on the spot. Not the point here.~

Turn the percentages into decimals. For example, 40% = 0.40. Then, multiply 0.40 by 360 (total degrees of a circle) to get 144 degrees. That's the angle you need to draw on your graph.

Therefore:
Apples -- 40% -- 0.40 * 360 = 144 degrees.
Oranges -- 20% -- 0.20 * 360 = 72 degrees.
Grapefruit -- 14% -- 0.14 * 360 = 50.4 degrees.
Peaches -- 26% -- 0.26 * 360 = 93.6 degrees.
If you want to add the four degree numbers together, you'll see they add up to 360, which is a full circle.

Hope this helped! Feel free to PM me if you still have trouble.

TYPE OF QUESTION: World Cultures/History
YOUR QUESTION: Alright so I have an essay due tomorrow for my World Cultures class about the fall of the Qing Dynasty (In China) and I'm having serious writer's block. I'm almost finished, I just can't figure out how to end it, and nobody in my family knows anything about the Dynasties. I was wondering if anyone would be open to me pming them what I have so far so they can help me wrap it up? (I wasn't sure if this was an okay question to ask... Since it isn't really a problem to be worked out or anything... if it isn't, just let me know and I'll remove it.)
