December 2010 International Math

<p>I put two questions about the circles. I don’t know if I missed any more. I have
the “someone-ate-my-pizza” shape and
six circle being tangent at 9 points and you are supposed to get the triangle’s perimeter</p>

<p>one that stated about 6 parts. It had 5 radii.</p>

<p>Yea i put that in the list
with radius of 2 and radius of 3, correct?
difference was 8/3 pi</p>

<h2>yes! </h2>

<p>Bump Bumpity Bump</p>

<p>anyone got any objection to any of these answers?</p>

<p>Was the 8/3pi question a grid in?</p>

<p>nope 10char</p>

<p>So, is the curve likely to be the same as the March one? I know the questions are the same, but the curve is determined by general performance, not by difficulty, right? So there should be some chance of deviation. (I really hope so!)</p>

<p>since the questions are 100 per cent the same and the curve is predetermined, all i can tell u is that the curves will likely stay. curves sucked in march, btw so that is a very bad news for us all :(</p>

<p>sorry for reviving a “necro’d” thread but i just got nervous when i found MP = NP. This is the consolidated list of math answers to questions from March 2010:</p>

<p>what does MP and NP stand for? if anyone knows, please tell me. thank you.</p>

<p>hey…guys remember the answer to the seventh day temperature question???i got it as 93…the question said the median temperature for the seven days was 88…so the temperature of the seventh day should be 93 right??</p>
