I'm 100% certain of those answers.

I got songster's #1 and danielsjang's #4, don't remeber anything else but on #9 the division line was perpendicular to 4 and you use similar triangles and proportions to solve.

How do you remember all of those numbers?

You write your answers down on your test booklet, which you're allowed to take out of the room.

As for #4, it comes out to four quarter circles of radius 1 at each of the corners. Therefore, the area in the center of the square is (square area) - (circle area). They asked for 100 times the answer, which is 100*(4-3.14) = 86. I got this one wrong on the test, but it's the right answer.

yeah I got 86 for number 4. number 6 i got 602, but i might be wrong. man, i can't believe i missed number 1. it's just long division, and i had 3 hours... grr!!

1. 217
2. 201
3. 314?
4. 314?
5. 799?
6. 867?
7. 588
8. 000?
9. 035
10. 269?

The ones with ? are the ones i had to guess

#4? I think it's not 4 circles
It's just one big circle infinitely close to the square. Well, I put 027 anyway (WAY OFF)

IF I DID put 035 on #9 then I'm 4/15 or higher

Well, I'm sure you guys got like >10
(I had NO IDEA beyond #10)

 By Songster87 (Songster87) on Wednesday, March 24, 2004 - 05:53 pm: Edit

No, it's definitely four QUARTER circles at each corner. Try and draw it following their instructions closely. #4 is definitely, definitely (4 - pi) = 0.86 = 86.

I think you may be right with #9 since a few other people had that answer as well. As for #6, I think the answer may have been 866 but I'm not certain. It would suck to get it wrong by one (like I did for #3).

 By Chamonix (Chamonix) on Wednesday, March 24, 2004 - 06:32 pm: Edit

Several of you put the same answer for number seven, the one where you multiply the binomials. I had 568 for some reason...bummer.

 By Chamonix (Chamonix) on Wednesday, March 24, 2004 - 06:34 pm: Edit

And I agree with Eastsoldier, it looks like one big circle to me.

 By Songster87 (Songster87) on Wednesday, March 24, 2004 - 08:22 pm: Edit

Try to draw it out. Just draw like 6 lines connecting two adjacent sides with a RULER. It is definitely, definitely not one big circle.

But in all fairness, on the test, since I tried to do it freehand and stopped after a few lines, I too initially thought it was one big circle (and this is why I got it wrong). But this falls apart because the radius would vary if the line was for example, 45 degrees (radius rt(2) - 1), compared to if it was close to 90 degrees (radius 1).

I'm absolutely, postiviely, 100% certain it's not one big circle. This is coming from a guy who put down the answer for one big circle on the test. Also, as a #4 AIME question, it was way too simple to be just "pi" since they know that would be the #1 random guess as well.

bump, does anyone else have any other answers? #8 or higher anyone?

 By Shhh (Shhh) on Wednesday, March 24, 2004 - 08:29 pm: Edit

what is AIME?

 By Theiceman (Theiceman) on Wednesday, March 24, 2004 - 08:39 pm: Edit

Songster's answers look like my friends answers...as usual I'm wrong, they're right

looks like I only got one (the first question)

even though i probably got question #6 wrong too (snakelike integers), my answer was 880 for comparative purposes

How did you get 201 for #2? (I know this is the right answer, just wanna know the reasoning)

 By Theiceman (Theiceman) on Wednesday, March 24, 2004 - 08:40 pm: Edit

oh yeah, 86 and 588 are right (my math teacher showed us how to do those problems right after the test)

Well, thank you Theiceman
Looks like it might not be official but I'll consider those to be the answers (pretty much)
I got 4 / 15, just as I expected
(I only solved four... just time consuming, no brain required ones...)

 By Strick (Strick) on Thursday, March 25, 2004 - 10:02 am: Edit

When do they announce or publish the official results?

 By Bobbyd (Bobbyd) on Thursday, March 25, 2004 - 08:22 pm: Edit

MOnday on the website.
