<p>Are we thinking -0 = 800, -1 = 790?</p>
<p>Can anyone explain to me why the answer to the uphill/downhill question was 4/7? I don’t remember what I gridded (:S) but I think it was 3/7. Did I confused which dist. was uphill and which was downhill? ARGH.</p>
<p>Also I second/third the posters asking: which were the ques whose answers were 21 and 3rad2? </p>
<p>I’m looking at 3-4 wrong in Maths. How many can you afford wrong to stay in the 700s?</p>
<p>This is horrible, when I came out I thought maths was my best section. I mean, my class exams I got 91%, with the next highest in class being 63%. Just goes to show that overconfidence is a *****.</p>
<p>I’m thinking -1 = 780. This was rather an easy test.</p>
<p>I don’t know. It was incredibly (and incredulously) easy, but I’ve noticed countless pitfalls that caught many people unguarded. I’m thinking -1= 790.</p>
<p>I am certain uphill downhill was 6/7. I even plugged in values to double check and every time I got 6/7.</p>
<p>does anyone remember the exact numbers for the uphill downhill Q?
i just remember uphill was 3/5 of the time and downhill was 2/5</p>
<p>Uphill was 2 mph and downhill was 4 mph IIRC.</p>
<p>was the line (-4,-3) experimental. I dont think i got it. </p>
<p>I got one that showed a line translated 3 units down. I put y=x+1. Is that right?</p>
<p>yes, right, i guess…</p>
<p>for the up hill and down hill one, uphill time is (3/5)t downhill time is (2/5)t , t being the overall time, the rate for uphill was 2 and for down hill 4, so the fraction of the downhill distance over the overall distance is simply: (2/5)t<em>4/((3/5)t</em>2+(2/5)t<em>4) when simplifying you get 4/7, note that rate</em>time gives you distance.</p>
<p>The question with three equilateral triangles formed by three line segments asking for an angle measurement tripped me up. Anyone have an answer?</p>
<p>Was the really obvious one like t= 4?</p>
<p>It was like “What is the distance from point t to line L if point S to point L is 4?” It was a rectangle? #8 on the multiple choice sect.</p>
<p>can anyone remember what prompts for the the 10 choices for food question or the shirt question were?</p>
