November 2009 SAT Math (US only)

<p>yeah sorry i got confused. should probably stop posting, i think i’m just confusing people with wrong information.</p>

<p>last time ill ask sry… but what was determined to be the experimental math? could u give me one or two qs on the experimental question?
was the number line from -1 to 1 with variables abcxyz one the experimental?</p>

<p>i don’t think abcxyz was experimental because im pretty sure i had a exp CR section</p>

<p>that’s what i thought, but apparently it isn’t. i don’t know what to think anymore.</p>

<p>the one with average rate (somewith 48)</p>

<p>btw i had the abxz question and my exp was writing.</p>

<p>huh. could’ve sworn that was in the 20-minute. do you remember that question, ironman? no one else seems to.</p>

<p>The abxz wasn’t in the 20 minute section, the x^3-y^3 was, I think.</p>

<p>@ sat1prep</p>

<p>are u serious?!?!?!?!
COME ON I WORKED HARD FOR MATH THIS TIME AND I SCREWED UP SOMETHING THAT INVOLVED CANCELING VARIABLES!!!</p>

<p>(c-a)-z>c-(a-z)
= c-a-z > c+a+z
=-z>z</p>

<p>stupid of me to not cancel</p>

<p>i tried to estimate using the graph. I hate myself. hope i can still get the 800…</p>

<p>Anyone remember the equations that actually went with each roman numeral? I know the one ironman posted was one of the true choices, and there was one other one. Can someone post the equations and the roman numerals they went with?</p>

<p>The question about finding “u” with the square slanted 30 degrees… What was the exact question??? becuase there was no circle around the square…there was just the x-y cordinate plane.</p>

<p>i got 2.5 becuase each side of the square was 5 making the hypotnuse 5 of the 30 60 90 tri</p>

<p>Bpop: A circle is inscribed in a square and the circle’s radius is 5. The square’s side is therefore 10. Since it forms the hypotenuse of the 30-60-90 triangle u is 5.</p>

<p>i seriously didnt see any circle in it…lol</p>

<p>wow…i am ****ed!!! this is ridiculous i knew how to do it but SOMEHOW didnt see the stupid circle…its frustrating</p>

<p>Does anybody remember the exact wording of the question about a+b+c+f and all the averages?</p>

<p>I don’t remember the exact wording. What do you need it for?</p>

<p>Because I’m worried I misread it haha</p>

<p>I’m trying to remember what I put and what some of the other choices were…do you remember the general idea?</p>

<p>The question was something like: “The average of two numbers A and B is 20. What is the average of numbers C and F if A+B+C+F is 10?”</p>

<p>The choices were like 0, 5, 10, 20.</p>

<p>hey, how about the amount of digits with the number “2” in them between 0 and 50? i got like 14.
and how about 302 for a grid in? like the 101st term in the series</p>

<p>Yes, both of those are correct.</p>
