was the radio question a MC question or a grid-in?</p>
<p>it was MC</p>

<p>Could someone tell me how they did the question with the area of the small box relative to the larger box. I made up a value for the length of the sides of the larger box and keep getting (3.125/100)^2. I could have put 1/256, B, or omitted it. </p>
<p>I</p>
<p>@thesos76: If you’re talking about one of the last problems of a section then it gave you one of the sides of the big box as 1.</p>
<p>@Rennir I am talking about the one where it asked for the ratio (if it’s a ratio, the values shouldn’t matter, provided that you’re consistent) of the area of the smaller box over the area of the larger box. The answer was apparently 1/256. It may have been experimental since I know I had an experimental math section.</p>
<p>The 50/51 was the classic example of the telescoping series. If you look carefully, all terms except the 1st and last cancel. Thus, the answer is 1-1/51=50/51</p>

See 1st example on this page.

<p>^woah, nice.</p>
<p>I’ll count myself lucky for guessing correctly :)</p>
<p>for the one where the answer was (sqrt(5)-1)/2, was there an answer choice that was (sqrt(5)-2)/2??? i really hope i didn’t pick that.</p>
<p>also, did anyone get a question with a pentagon inside a circle and how many times it can touch? i said 5 :(</p>

@lucasw
i think that was an experimental</p>
<p>@lucas I dont think so. There were 3 simpler choices and two sqrt - 1 questions. Only the last one was sqrt5 -1 I’ll count myself lucky for guessing E.</p>
<p>i might have put that one and i’m just remembering it wrong… hopefully 800 without stupid mistakes
plus i think i remember guessing e</p>
<p>Lucsaw, i think it’s 10</p>
<p>It’s ten. I can draw it out for you if you’d like.</p>
<p>
</p>
<p>That’s another telescoping series. After cancelling, it’s 1(2)/99(100), which is 1/4950</p>
<p>@cooldude I answered the exact same as you did with the overlapping question. I put it as 2 first, reread it, and changed it to 1. :(</p>
<p>what was the answer to the caffeine,tea,cola?</p>
<p>It was Cola, Tea, Coffee.</p>

<p>Wasn’t the question asking for the sum of every number in the sequence up to 50?</p>
