January 2013 SAT Discusion

<p>Pretty sure that was experimental section so it won’t count.</p>

<p>i don’t remember any answer .308</p>

<p>I didn’t have that one</p>

<p>Gah, how was the clubs one 4? I omitted it…</p>

<p>There were 11 only in 1 club, 9 in math, 10 in academic. Therefore there were a total of 19 club members. Out of these, 11 are accounted for once, leaving 8 apparent members, except they were all double counted, thus there are 4 in both clubs.</p>

<p>Oh wow, thanks. I got 8 but somehow that didn’t click.</p>

<p>Anybody remember how the sequence 100, 2, 2, 2, 2, 2… question was phrased? Did they want to know how many numbers in sequence are > 2? I’m second guessing myself here.</p>

<p>Yes, you’re right :)</p>

<p>^^okay I thought I was going crazy when I got a billion 2’s</p>

<p>Do you remember what the question asked?</p>

<p>

</p>

<p>The phrasing was something in the spirit of this:
[The first term in a sequence is 100. Each subsequent term is the quotient of the term before it and one half of that term. How many terms in this sequence have a value greater than 2?]</p>

<p>I answered [A) One]. The second term is equal to 100/(100/2) = 100/50 = 2. The third term is equal to 2/(2/2) = 2/1 = 2. At this point, it should be obvious that every subsequent term would have the same input and output as the second term. As you said, the sequence would thus be 100, 2, 2, 2, 2, 2, 2… As the question asks for terms >2, and only the first term is greater than 2, the answer was one. Hope that helps.</p>

<p>Thank you so much Radicalness! Won’t have to worry about that one anymore. ;)</p>

<p>Hey guys! I thought math and writing went well. I messed up kinda bad on my first reading section. Does anyone know the answer to the question where there was a square in between two triangles. There were four arc lengths and It asked for their total. I think I got 24pi</p>

<p>Between two circles my bad lol</p>

<p>I don’t remember that one. Probably was part of the experimental section.</p>

<p>I’m hearing that the answer to that is 16pi…I didn’t put that though</p>

<p>Circles not triangles?? Was that the last question on one of the sections?</p>

<p>Yes it was the last question on a section</p>

<p>Hey what did u guys get for the one where it was like 1000<a<b<10000 and \something about the digits being the same?</p>

<p>Radius was 6 and it wanted the bold arc lengths. Each was 240/360 degrees if each circles so I got 8pi + 8pi = 16pi can anyone confirm? Was that experimental?</p>
