post only math here (just to make everyone's life a little easier)

 By Scion (Scion) on Saturday, March 27, 2004 - 07:25 pm: Edit

i hate the q/cs. was the first one A? does anyone else remember some of the first few q/cs? damn i hate those. anyone also remember ANYTHING else from the math, whether u got it right or wrong?

Please post all the qualitative comparisons...I want to make an official list...I can't remember anything...HELP!!!

Math section 2 experimental?

 By Jm2006 (Jm2006) on Saturday, March 27, 2004 - 07:34 pm: Edit

okay i'll see if i can start.

1) y is 3 less than x (something to that effect?)

column a: x
column b: y+2

 By Phantom (Phantom) on Saturday, March 27, 2004 - 07:38 pm: Edit

*r^2-t^2=1 was D.

*palindrome one = C

15) graph with shaded region, line l was B
(y-coordinate > x-coordinate)

if i think of more, ill post them

About the question with the 3-D figure consisting of polygonal faces, I know now that the answer was 4. Does anyone remember what letter that answer was? I'm pretty sure I put C.

 By Modestmouse (Modestmouse) on Saturday, March 27, 2004 - 07:42 pm: Edit

It was four. I have proof, lol. TETRAHEDRON! I'm not sure. I think it might have been B. Because weren't the choices:
A. 3
B. 4
C. 5
D. 6
E. 7
Heck. Maybe it was different. I just know I messed up my verbal. I mean. WTF. How am I supposed to know what abstemious is?

 By Haithman (Haithman) on Saturday, March 27, 2004 - 07:49 pm: Edit

1) y is 3 less than x (something to that effect?)

column a: x
column b: y+2

lol im sorry but is that really THAT hard?

 By Scion (Scion) on Saturday, March 27, 2004 - 08:34 pm: Edit

haithman, we're just trying to remember every q/c, ok?

 By Flameball63 (Flameball63) on Saturday, March 27, 2004 - 09:14 pm: Edit

Bump this baby UP! I wanna know the QCs...that screwed me OVER.

 By Eastsoldier (Eastsoldier) on Saturday, March 27, 2004 - 09:48 pm: Edit

I heard - from the examiner - there were several versions of the test

But I get this feeling there weren't

Can anyone fill me in?

 By Scion (Scion) on Saturday, March 27, 2004 - 09:51 pm: Edit

hell yeah they were. i probably looked like i was cheating cuz i looked over at someone who was using a calculator when i was doing a section 2 verbal. so HELL YEAH this time they had multiple versions. by the way, anyone have the answer choices to the math m/c about the grad reqs?

 By Auburnwareagle (Auburnwareagle) on Saturday, March 27, 2004 - 10:33 pm: Edit

i had a section 2 verbal as well........talk about shocked when i opened my book and saw a double passage in section 1

 By Crypto86 (Crypto86) on Saturday, March 27, 2004 - 11:59 pm: Edit

Nice - all the tough QCs i got right. I think I got all of those right. Ha - I can get the r^2-t^2 = 1 right easily yet I really had to look at number 1. Weird.

 By Simplyloved (Simplyloved) on Sunday, March 28, 2004 - 12:18 am: Edit

my answer for the multiple choice grad request thingies was 16. G+B=156 g=2B, 3b=156 b=52, b=104, the necessary units were 120.. she needed 16 more units to graduate

 By Bcrichsolo (Bcrichsolo) on Sunday, March 28, 2004 - 12:19 am: Edit

does any1 remember what the last grid in math was...i heard it was 1/3 but i dont remember the problem

 By Crypto86 (Crypto86) on Sunday, March 28, 2004 - 12:20 am: Edit

Yes - it was 1/3.

 By Gastudent123 (Gastudent123) on Sunday, March 28, 2004 - 12:34 am: Edit

Why is the answer B for number 15 (y coordinate>x coordinate)

 By Sarang (Sarang) on Sunday, March 28, 2004 - 01:55 am: Edit

hows about the one the last question (10) of the short math section
sumthing w/
p percent of 1/p equals 1 percent of 1

 By Hobbes344 (Hobbes344) on Sunday, March 28, 2004 - 01:57 am: Edit

Well, I was too lazy so i graphed it and i got .333. Im not sure though.

 By Bfjava (Bfjava) on Sunday, March 28, 2004 - 02:21 am: Edit

mmmm, no!

.333 is the "obvious' answer. considering it was a question towards the end of the section, do you really think it'd be that easy?

Just come up with an example and you'd find the solution. For 1/2 use 6/12 and for 1/3 use 4/12. 4/6 is 2/3 which is 66.7%

 By Hobbes344 (Hobbes344) on Sunday, March 28, 2004 - 02:42 am: Edit

I think we're talking about different problems here. Im talking about... that one that bc = 5, and b = 1 + 1/a that one was .3333 i believe. And for the question that you said, i got 2/3, too. ;)

 By Xforce (Xforce) on Sunday, March 28, 2004 - 03:09 am: Edit

Yea how did u do the r^2 - t^2 = 1 problem. The choices were (A) r^2 ,and (B) t^2

 By Scion (Scion) on Sunday, March 28, 2004 - 04:01 am: Edit

yeah i put C, but A LOT ppl proved it was D.

 By Kevinkleinz (Kevinkleinz) on Sunday, March 28, 2004 - 08:41 am: Edit

Yeah, 'twas D.

1st Case:

Let r = sqrt(2)
Let t = 1

r + t > r - t

2nd Case:

Factor first-- (r + t)(r - t) = 1

Now one possibility is (r + t) = 1/4 and (r - t) = 4

Solving you get 2r = 4 + 1/4
r = 2.125

So t = r - 4 = 2.125 - 4 = -1.875

So in this case, r + t < r - t

 By Bcrichsolo (Bcrichsolo) on Sunday, March 28, 2004 - 11:23 am: Edit

That problem took me 10 seconds. If you look at it you realize in the origional equation, if you use positive or negative numbers it will come out the same because they are squared. Then you look at the two choices and see that it depends whether they are + or - and its D

 By Spright (Spright) on Sunday, March 28, 2004 - 12:48 pm: Edit

Okay...I shouldn't have thought about the problems I was unsure of as much as I did, because now I realize I probably got them all wrong, but here are two questions:

1.) The a in a triangle = 2^a +2. What is a+1 in a triange? I put 2x'a in a triange,' but now realize that's probably wrong.

2.) The cube that has letters on each face...what letter is across from x? Is it B?

 By Gmf05 (Gmf05) on Sunday, March 28, 2004 - 12:51 pm: Edit

Spright 1. 2/a+1\ - 2
/a+1\ = 2^a+1 + 2...right?
2/a\ = 2(2^a + 2) = 2^a+1 + 4...subtract 2 and you've got 2^a+1 + 2

 By Spright (Spright) on Sunday, March 28, 2004 - 12:57 pm: Edit

sigh...that's what I thought of after I'd already finished the test.

I know this is an annoying thing to ask but, would it be possible (assuming, hah, an 800 verbal) to get a 15-something and still miss around 4 math?

 By Haithman (Haithman) on Sunday, March 28, 2004 - 01:10 pm: Edit

Miss 4 math and you prob have like a 740

 By Best_Wr (Best_Wr) on Sunday, March 28, 2004 - 01:10 pm: Edit

I said n+2n= 156 or something and the person we are looking for had 2n, which is 104. So I did 156-104, coming up with 52. Is that right?

 By Musicbuster007 (Musicbuster007) on Sunday, March 28, 2004 - 01:11 pm: Edit

Spright
The answer was 2 times /a\
2x 2^a+2
2^(a+1)+2
I think

 By Musicbuster007 (Musicbuster007) on Sunday, March 28, 2004 - 01:13 pm: Edit

Best_WR
Don't do 156-104. 156 is the two ppl's score combined. 120 was the requirement so 120-104 (how many already obtained) = 16

 By Spright (Spright) on Sunday, March 28, 2004 - 01:23 pm: Edit

Musicbuster: That's what's bothering me about it...was the '2' included in what would be affected by the 2^1?

SIgh.. I hate SAT math.

Anyone know on the cube one?

 By Spright (Spright) on Sunday, March 28, 2004 - 01:50 pm: Edit

wait. nevermind. what I wrote about the triangle one didn't make any sense..it should be the 2*triangle - 2, I believe.

 By Crypto86 (Crypto86) on Sunday, March 28, 2004 - 01:57 pm: Edit

Yes - the answer was E

2/a\ - 2

 By Flameball63 (Flameball63) on Sunday, March 28, 2004 - 01:59 pm: Edit

Triangle A should be E...2/a\-z...because, you plug in numbers, and ONLY E worked. Try it.

/a\=2^a+2
use 3=10
/a+1\=4=18

Only On E...did the answer came out like that...
2(10)-2=18...(with every other number, it works out too...) So, I conclude, the answer was definitely E.

 By Haruhara (Haruhara) on Sunday, March 28, 2004 - 03:15 pm: Edit

what about the cube one with the X face thing, i put B for that one

 By Bcrichsolo (Bcrichsolo) on Sunday, March 28, 2004 - 03:18 pm: Edit

the cube was B i think... the triangle was definatly 2/a\-2

 By Melissamelissa (Melissamelissa) on Sunday, March 28, 2004 - 03:19 pm: Edit

what was the questions for the last grid in again? the triange thing? i dont remember

 By Melissamelissa (Melissamelissa) on Sunday, March 28, 2004 - 03:21 pm: Edit

what was the one with like ...whats the highest difference between a 4 digit # with 3 odd numbers and a 3 digit # with 3 odd numbers?

 By Tired_Student (Tired_Student) on Sunday, March 28, 2004 - 03:27 pm: Edit

i dont remember having that, maybe it was experimental.

 By Scion (Scion) on Sunday, March 28, 2004 - 03:28 pm: Edit

melissamelissa, it was 9887 (9998-111)

 By Scion (Scion) on Sunday, March 28, 2004 - 03:32 pm: Edit

and to concur, it WAS -2 for the last m/c of the test w/ the triangle defined operation. and

Best_Wr

I said n+2n= 156 or something and the person we are looking for had 2n, which is 104. So I did 156-104, coming up with 52. Is that right?"

unfortunately, that isnt right, but i MIGHT have done the same thing. SO 52 WAS an answer? damn ets, tricking poor tired souls.

 By Flameball63 (Flameball63) on Sunday, March 28, 2004 - 03:42 pm: Edit

What was the complete question with the grad? Can anyone recall the COMPLETE question? I am pretty sure I had 16...but then, one day after, my amnesia is officially kicking in, and I am right now paranoid. Can SOME! PLLLEEEEAAASSSEEE frame the whole grad question!!!!!

 By Haruhara (Haruhara) on Sunday, March 28, 2004 - 03:48 pm: Edit

john has twice the number of credits as jane does. they have 156 credits altogether. how MANY MORE CREDITS does john need to graduate (assuming 120 credits for graduation)? answer is 16.

 By Scion (Scion) on Sunday, March 28, 2004 - 03:50 pm: Edit

hey flameball, that amnesia is kicking in here too.

 By Musicbuster007 (Musicbuster007) on Sunday, March 28, 2004 - 04:13 pm: Edit

crap... yeah the triangle thing was E... I forgot that the 2 for be distributed over to the left over +2, leaving 4, so we'd have to subtract 2... noooo!

 By Songster87 (Songster87) on Sunday, March 28, 2004 - 06:05 pm: Edit

Hey, does anyone know if 12 was an answer choice to the 120-credits one? I know I solved it correctly, and I know I picked a number in the teens, but for some reason, I vaguely remember picking 12. But...that wasn't a choice, correct?

My memory's all fragmented so if 12 wasn't a choice, then I definitely picked 16. =P

 By Songster87 (Songster87) on Sunday, March 28, 2004 - 07:44 pm: Edit

Or, actually, does anyone know if 16 was choice A in the 120-credits question?

 By Scion (Scion) on Sunday, March 28, 2004 - 07:48 pm: Edit

o god songster, this sucks. im thinking the same way u r. i coulda sworn i got the answer, but i mightve made a stupid careless mistake...
how many times have u taken the sats?

 By Bcrichsolo (Bcrichsolo) on Sunday, March 28, 2004 - 09:11 pm: Edit

Ok, in some math section i remember a problem taht was in the bottom left hand part of the test page on the left page. I think the answer was A) 19. Does anyone remember this!??!?

 By Simplyloved (Simplyloved) on Sunday, March 28, 2004 - 09:21 pm: Edit

do u rememeber anything else about the problem?

 By Skapoor1 (Skapoor1) on Sunday, March 28, 2004 - 09:23 pm: Edit

yes songster, it was choice a, 16

 By Songster87 (Songster87) on Sunday, March 28, 2004 - 09:42 pm: Edit

Scion, I took it in 7th and 8th grade, but this is my first time in HS (as a junior).

 By Melissamelissa (Melissamelissa) on Sunday, March 28, 2004 - 11:57 pm: Edit

wait what was the answer to that one questions...it was like

a,b,c

b= 1/something
c=1/something
whats a...?

i dont remember the whole Q

can someone explain the square rectangle thing? i've heard numbers from 38-44...seems like most say it's 44.
can anyone clarify this?

 By Billiam2 (Billiam2) on Monday, March 29, 2004 - 10:01 pm: Edit

I'll clarify:

 By Blahdude (Blahdude) on Monday, March 29, 2004 - 10:15 pm: Edit

the credits question:
person B has twice as many credits as person A and both had a total of 156..you need 120 to graduate so how many more does person B need?
3x=156
x=52
person B has 2 x 52 = 104

i got 44 on the square rectangle one too

 By Melissamelissa (Melissamelissa) on Monday, March 29, 2004 - 10:17 pm: Edit

what about the a.b.c thing againg? bc=5 and wutever? wut was the Q again

 By Aruben537 (Aruben537) on Wednesday, March 31, 2004 - 09:15 pm: Edit

For the problem r^2-t^2=1, I am a little confused on how the answer would be D. I believe the choices were (A) r^2 ,and (B) t^2.

Since there can't be negatives or anything, r^2 must be bigger...or so i think...in the proof given by Kevinkleinz, it is proven that r+t can be both greater than or less than r-t, but in both of his examples, r^2 is still greater than t^2.

So I am just confused as to if there is another proof, or if someone posted something wrong possibly

Also, I am really hoping for the 800 in math, and so far this is the only problem I know of that I could have gotten wrong (i put A), so with the scales is it still possible to get an 800 while missing one. Thank you

 By Kevinkleinz (Kevinkleinz) on Wednesday, March 31, 2004 - 11:18 pm: Edit

No, the columns were not r^2 and t^2. Column A was r+t and column B was r-t. And so, the answer was D.

 By Aruben537 (Aruben537) on Sunday, April 04, 2004 - 05:35 pm: Edit

There is a series in which each number is one more than the reciprocal of the previous number.

a=?, b=(1/a)+1, c=(1/b)+1, and bc=5

The question was to solve for a.

It came out to =1/3, and b=4, c=1.25
