October 2011 SAT Mathematics

<p>I mean was there an experimental math section within the whole test that I’m talking about.</p>

<p>ahh crap.</p>

<p>Somebody shoot me.</p>

<p>@dchau503</p>

<p>Yes, there were two grid-ins. The experimental was the section with a problem about ice cream</p>

<p>Pleaseee let -1 be 800</p>

<p>For the median one with 101 terms did you guys get 36.</p>

<p>for monday question did you get 9?</p>

<p>DancinggBear I got 36 & 9</p>

<p>yes dancinggbear ^^</p>

<p>Great! </p>

<p>for the I,II,III question on the last 20 min section did you guys get none?</p>

<p>yep, none!</p>

<p>@DancinggBear I got none.</p>

<p>for the median one, was one of the choices 35?</p>

<p>Anyone remember the problem with I II and III in it?</p>

<p>@Elementi</p>

<p>Uhh, ice cream? I don’t remember that being on the math test. :(</p>

<p>^It was something about which of the following has to be an odd integer</p>

<p>@dchau503
I didn’t have it either, that was an experimental section.</p>

<p>what was the question with 27^x=ka, 3^6x =81 or something like that? What was the answer to that?</p>

<p>@dchau503
Then you didn’t have the experimental math then?</p>

<p>@ctsv300</p>

<p>If x is an even integer, then which of the following an odd number?</p>

<p>I. (1/2)x
II. 2x
III. 3x</p>

<p>I chose none.</p>

<p>I thought was. x is an odd integer, which of the following are also odd integers I 2+x II 2x III 3x, ??</p>

<p>@ctsv let x = 4, 1/2(x) = 2, which is an even</p>

<p>@Sonic7</p>

<p>27^x=ka, 3^6x = 81a^2</p>

<p>You take the square root of 3^6x = 81a^2, and it changes to 3^3x = 9a. If you plug in 1 for x, it looks exactly the same as 27^x=ka, except its 9a instead of ka. So K=9</p>

<p>the ends are open. it was like a toilet paper roll.</p>
