The Thing

Americium 241 is also a gamma emitter, at I think 0.06MeV.

Try googling bits and bytes. That will tell you all about how computers change 10001010111010101 to human understandable language.

What is the real name of H3O+? I've always called it hydroxonium but my teacher tried to force me to call it hydronium...

Try this link: http://support.microsoft.com/default.aspx?scid=kb;en-us;317189 Or you can use the most effective way that I often use when in doubt: WARNING: Not for the faint of computer h4x0r sk1llz0rz: Step 1a: back up all useful data. Then reinstall the whole frigin system!

This is outrageous! My answer of the oxygen atoms was indoubitably the correct one. You give me too little credit.

Pssh. Too simple. It is obviously an array of oxygen molecules being lined up by some sort of gigantic oxygen molecule lining up machine. That's my answer. Barely a challenge .

I'm inclined to think that I need to come up with two equations for each of the statements you gave me and then cancel out some variables leaving only two. Either that or I'm totally on the wrong track. I have an exam in a few hours. Must get ready. I'll work on this problem when I get back.

9C2. Either that or 9P2. I can't remember which. Look on your calculator for the buttons nCr or nPr. They're usually 2ndFunctions, and a good scientific calculator will have them. And google permutations and combinations.

Degrees to Radians: [math]\frac{DEG* \pi}{180}[/math] Likewise, Radians to Degrees: [math]\frac{RAD*180}{\pi}[/math]

In my school, all the math teachers use the mnemonic SOH CAH TOA. It's so ridiculous unimagniative and terrible-sounding that everybody remembers it. Meh, whatever floats your boat. Trig ratios for special angles are very easy to memorize (even if you don't know radians) and if you can't memorize you can draw a triangle on the spot. The special angles include 0, 30, 45, 60, 90, all angles in other quadrants with these reference angles, and all coterminal angles. All you need to know is the sides of a 45-45 right triangle (1,1, and root 2) and a 30-60 right triangle (1, 2, and root 3), and how to draw a unit circle. You should know these fine. Then just know the +/- of each trig ratio in each quadrant and you're set for special angles without calculators.

I'm predicting what it next shows in the crystal ball instead of it predicting what I'm thinking! T3h crystal ball hath been outwitted by t3h 1337 psych1c sk1llz0rz. No seriously, Connor's right. Multiples of 9. Mathematically, say you have a number 10x+y Add the digits: x+y Minus that from 10x+y, so 10x+y-x-y=9x. All multiples of 9, x depending on the tenth digit of your number. But that hardly matters when all of the multiples of 9 have the same symbol.

I demand harder questions! No seriously, good job cosine.

A Caesarian Cypher? As in the one Caesar used? Shifting all alphabets by a number up and down so a becomes b, becomes c and things like that? As for the text I have no clue to what it means .

NO!!!! Dot TK's putting ads now? When I used it (a couple of years ago, maybe one or two), it didn't have any ads.

Templates are all over the web. Google "free web templates" and you get excellent sites such as supremetemplates for thousands of free pre-made templates (you have to keep a link underneath for copyright reasons though). To make your web URL less long, I highly recommend DOT TK. It allows you to create a short domain name such as yoursite.tk. The website is http://www.dot.tk.

168 kg. Come on, I'm sure you have harder questions . And I'm 99.999% sure that my solution for the cube is right (69 for the surface area, choice A).

You can use a Stirling cycle Cooler. Some small coolers are about the length of a 30cm ruler (so, about 30cm). They don't have a lot of moving parts - just a linear motor driving a piston. It's very efficient and larger ones can cool to cryogenic temperatures. Of course, it takes up a bit of space.

Sooo...can you find the answer to the question? As in, the answer given by whoever created the question. Next question please!

Well I'm a 10th grader currently volunteering at my locay Y as a lifeguard. They won't lemme rest as often as the other "hired" lifeguards (they have 15 min per shift), and I stand hour shifts, standing, because there's only 1 chair and the lifeguard usually sits there. Learning how to scan and stuff... They won't let me jump in either because I'm not officially hired and have to be over 17 to BE hired. Age discrimination! Boredom sets in in about 3 minutes. I usually end up talking with the "real" lifeguard about completely non-pool related things and biking home with a sore neck. 50m in 1 min isn't a big deal. 100m in 1 min is much harder (no duh) - non-Olympic or amateur competition free & sometimes fly speed.

That's funny - I got 69... Lemme go through my train of thoughts again. The area of the hexagon is calculated first. How? Well, there are 6 equilaterial triangles in the hexagon, each with side length of 2 root 2 (root 8). Their areas can be found with the formula [math]\frac{1}{2}bcsinA[/math], so multiply that by 6, and we have [math]3*2\sqrt{2}*2\sqrt{2}*sin60[/math]. That's about 20.7846. We have 1 complete face for the cube, namely the face of the cube that is facing you. That's a complete face - the plane doesn't cut through it, so [math]4^2[/math] The right face of the cube is missing a corner (the small triangle cut by the plane). The left face IS a corner! So we can put those together to get another complete face. Again, the top face is missing a corner, while the bottom face is a corner. Add those two together. So overall, we have another [math]2*4^2[/math] Adding them all together yields 68.7846.

Ahahahahahaha. Mathematician, me? No I'm just a grade 10 that is not particulary bad at math. Okay so the big hexagon has the area of [math]3bcsinA,[/math], so [math]3*2\sqrt{2}*2\sqrt{2}*sin60[/math]. What is that calculated? Iunno. Okay, we have two large sides of the cube, so that's [math]2*4^2[/math]. The surface on the top of the cube plus the surface on the bottom adds to another side of the cube, so another [math]4^2[/math] Basically all sides missing a corner has a corresponding part on the opposite side that is a CORNER missing the REST of the side. So yeah, more of those. So are there a few triangles? Each has area of 2. Just add them all together? Tell me if I did something wrong - I can't think anymore. Too tired.

Well, while you were having fun doing the problem , I contented myself with about 6 different final exams from 4 different teachers. It's the end of the semester for me, and in about 2 days I have 2 provincial exams to write. So I didn't really think about the problem. But now, are you sure you drew the cube correctly? I can't visualize what this thing looks like. Is the hexagonal plane like a knife cut, as in, one flat plane (well duh a plane's flat)?

Aaaarg, lots of tedious work. The hardest part is wrapping my mind around this model. I simply can't visualize this in 3D space. Maybe it has to do with my speakers on full volume and very discordant music playing.

Maybe you dreamed that you were stabbed because you got a pain in your neck... I had several strange dreams when I was younger, after which I would usually have irresistable urges to laugh hysterically. (I can never remember what they were about). It hasn't happened for a few years, but it was definitely the strangest feeling. And also, everything in the room would be especially bright.
