November 2010 SAT - Math

<p>@dipole. i gave u cordinates of points and asked to arrange the sides form least to greatest.</p>

<p>also there was question that showed a picture of a grid and asked in which regions would a+b>0. i said regions 1 and 2. anyone put this down too?</p>

<p>the one with 7^1600, i got 1 as the answer. triangle inscribed in a circle and you had to find area, i got 24pi. the one with x’s i got six, the one with 4ax^2-bx+4c i got 120 and i don’t remember any others.</p>

<p>then for the print factorazation of 2^20 -1.
i put (2^5+1)(2^5-1)(2^10-1). it was like C i think. conformation?</p>

<p>Also, I think it was #14 in the 20 min section, the sum of the components of the average of 15 was 75 (D?)</p>

<p>i got 75 here</p>

<p>Confirm all of those, chemistry30. Except I don’t remember if I got exactly 120 for that one, but I remember 120 something, so I’m assuming that’s right and just my poor memory. Did you have one about two hoses filling a tank at different rates?</p>

<p>i did not get the one with what is the max amount of increasing months in a row. it was on a graph. I dont remember exactly what the question said.</p>

<p>I can also confirm chemistry30’s responses. Also, I got the tank question. My answer was 36.</p>

<p>i got 18 hours for the hose one, dun ask why i guessed, 0 for the 4ax^2-bx+4c , and 1 for the 7^1600, and wut letter choice was the one with the 100th or 101th term with respects to h, it was like second to last before the grid ins? i got 770 in the october one, and this was def harder</p>

<p>There were most certainly multiple versions, as most questions being listed bear no resemblance whatsoever to any questions I had.</p>

<p>Having had four math sections, I assume that I had a math experimental.</p>

<p>

Same. Pattern worked out to be: 7, 9, 3, 1, 7, 9, 3, 1… for increasing exponents on seven, so seeing how many cycles of four there were in 1600 yielded 1 as the units digit.</p>

<p>@esthetique ya i got 1 and 2 for the regions one.</p>

<p>It appears you got an experimental math since i did not have either the prime factorizaiton one or the one with the triangles.</p>

<p>There was one I’m not sure I got… there was a graph showing how much $$ two people had over a span of ten weeks. We were supposed to find how much money they had when they both had the same amount. And the answer I kept getting wasn’t one of the choices…</p>

<p>the card problem was “how many cards does someone have to pull out before they KNOW they have 7 green cards”. theres 40 cards, 10 of each color (10 green)…to KNOWWW>.you gotta take out the 30 other colored cards, then 7 green. or 37 cards</p>

<p>dipole i think you’re referring to Eagles haha</p>

<p>

Using the slopes of the lines to track how much money they had on each week showed that the lines met at $60.</p>

<p>tjb11, yes that is what i got as well.</p>

<p>Spazzy, the answer for that one was 60. For the terms question, I got h+100.</p>

<p>Crzygamer I had this question and I just omitted I tried to put the numbers starting with the middle (24) but I really didn’t understand the question…lol</p>

<p>but its the least amount of times that you can KNOW if ur blindfolded. ■■■■■</p>

<p>think about it. if u have 36 cards…you MAY have only picked up 6 green and 30 of the other colors.</p>

<p>what bout the g(x) = -2f(x) and asked for minmum. i got -2 anyone else?</p>
