Math (December SAT 1)

<p>so did any1 else see the q about cube/plane/cross-section</p>

<p>Yeah, I put 3, guessed between 3 and 8.</p>

<p>keeprolling - that’s how i did it! It was just one of those questions that I was kind of iffy about, but thanks :)</p>

<p>And this is really getting confusing - I’ll start an AIM chatroom to discuss the test that we had; i guess that includes me, keeprolling, voodoosanta, quicksandslowly, and a few others?</p>

<p>oh yeah and my AIM is stablestar2222 if you want to</p>

<p>sugarincarnate, send me your aim</p>

<p>^ yo i dont remember that question T.T pm me ur chatroom if u like</p>

<p>my AIM = stablestar2222</p>

<p>im pretty sure the cross section couldnt have 8 sides. 3 is very possible.</p>

<p>anybody remembers the question where they show you a picture of equilateral triangles whose sides are 8 and they ask you how many stick you need to make 50 equilateral triangles???</p>

<p>For the supplementary/complementary angles one, </p>

<p><1 was comp to <2
<3 was comp to <4</p>

<p>It was something like, <4 was opposite of <2 which made them vertical angles … which made them congruent.</p>

<p>And since both of them were congruent, that means the angles they were complementary to had to have been congruent (<1 and <3), too.</p>

<p>Something like that… I wish I had the actual diagram hehe.
Hope this helped!</p>

<p>There are so many versions of the test! Our school (we’re big) had apparently 4 different versions. Apparently you can tell which versions were the same by using one of the test codes (anyone have AEEG7177 or something?) The last letter tells you which version you have.</p>

<p>BTW, did anyone have that questoin with the semi circles and the dotted lines? What were the numbers? I could swear I got 18 … one semi-circle was 2pi, the triangle was sqrt(20) (or 2rt(5)) and 4. </p>

<p>So … I got 2pi = 1/2dpi, which means the diameter for that circle was 4. And hten … I don’t remmeber what the 2nd circle was. And the triangle meant that the line was 2. … which means if I got 18, the semi-circle left had to have been … 6pi? Anyone? 6pi = 1/2dpi, so d = 12 … ? </p>

<p>12 + 4 + 2 = 18?</p>

<p>^101 i believe. 3+ 2(49)=101.</p>

<p>ariger, i put 101
what did you put?</p>

<p>ok, so who wants to open an aim chatroom for the ones who have the same test as me?
i think is ariger, reeya, sheena, zhonginator… ?</p>

<p>there was a cool q about adults having to leave a room.</p>

<p>

So the answer is A. 1 only?</p>

<p>i left it blank, ran out of time</p>

<p>“anybody remembers the question where they show you a picture of equilateral triangles whose sides are 8 and they ask you how many stick you need to make 50 equilateral triangles???”</p>

<p>Oh yeah! I got 101 for that.</p>

<p>Yeah, that’s right, I was thinking about 3D structures. :/</p>

<p>i got 101 as well.</p>

<p>i had the same version astropuff!</p>

<p>the one about one kid and 99 adults in the room, 1% question?
i put that 50 adults have to leave.
anyone?</p>
