Official March SAT Math Discussion 2008

<p>no but i mean there was one that was a little more horizontal when compared to point P.. you had to first reflect it over the line to the left of point P then the one on top of that point</p>

<p>Ohh I see what you're saying... Hmm, so it's quite possible that I switched the order of the reflections. I really don't remember.</p>

<p>OK, I just realized the order doesn't matter. lol.</p>

<p>i re-read that one 3 times, it was definetly that order making it B</p>

<p>does anyone remember the question of what time interval was the fastest / closest to home? it was like 1 mile away from home during a 1/2 hour walk and he came home like after 3 hours?</p>

<p>Oh was that one the one with the graph?
I put 0.6 -> 1.0 I think
Because that was when the slope turned negative, meaning distance from home was decreasing.</p>

<p>yep thats the right one
do u know why she used 1st person narration
to convey the emotions motives of others?
or to tell events in order..</p>

<p>Yeah, it was the one was the graph. I wasn't sure if they wanted the time when he finally arrived at home or when he was close to home??</p>

<p>the scale 4 the math will b horrible since it was so easy
im thinking one wrong equals a 760?</p>

<p>this may be obvious but the first grid in was 60 correct?</p>

<p>which one was that</p>

<p>something about a percentage. i think iwas 25 percent</p>

<p>i think it was sixty; i checked w a friend but just to be sure?</p>

<p>i forget that one was it the one like 125 percent of a number or something</p>

<p>i found another one!
the one with the bigger number, x and y. it was tricky cause the number you sovled for was the smaller number, which was 8. but the answer was 12</p>

<p>it was like x+y=20 and.. 3/2x+__=y i think</p>

<p>i think that was on the experimental sectio manybe?
i didnt have it although i do remember gridding 12</p>

<p>no its not expeirmental i takled to liek 2 ppl abt it
and it's not in the gridding section</p>

<p>wat was the exact question about
was it substitution and elimination cuz i never used that in the test</p>

<p>were they graphs?</p>

<p>no it was the first grid in.
it was like.. 25% of what number is equal to 15 i think
i'm positive the answers 60 tho cuase i asked a few of my smarter friends</p>

<p>ya that one was 60
but the X plus Y equals 20 etc. how was that one formed
wat section was it etc. MC?</p>

<p>the computer chip problem: doubles every 18 months. How many times its original is the number after 12 years. say you pick 2 to plug in. 2, then 4, 8, 16, 32, 64, 128, 256. so thats how a lot of people got 256...but the question was how many times more was the final....therefore you must divide 256 by 2 and you get 128....i'm 100% on that one</p>

<p>Yep I got 60</p>
