<p>Cube one 54</p>
<p>F(6) 1.5 I think</p>
<p>36-36+9/6=9/6</p>
<p>@eaglesk- 3/2</p>
<p>any chance it could be f(6)/6=9 and multiply 9 times six to get 54?</p>
<p>For the marker and rest stop one…
I recall my answer being 8:3.</p>
<p>The question stated that the trail was 19 miles long and that there was a marker every 2.5 miles and a rest stop every 6 miles. There was also a marker at the beginning of the trail (I believe that the question did NOT state there being a rest stop at the beginning of the trail). </p>
<p>So there would be 8 markers and 3 rest stops, making the ratio 8:3, right?</p>

You find the surface area of the three sides of the cube then add the three sides that have one square taken away and add 3 to that an that’s your answer</p>
<p>cube of 3x3x3 blocks. Surface area is
length of once face X width of one face X number of faces
3x3x6=54
Top corner 1x1 block is removed. What was once the top face is inside. What was once the leftside face is inside. What was once the frontside face is inside.</p>
<p>So removing a block doesn’t actually change the surface area.</p>
<p>I believe I got that problem wrong, then.</p>
<p>if your first two sections were math which one was the expiremental?</p>
<p>^ 7:3??

<p>for the “k” question were you supposed to grid in 16 or 128? I can’t remember and I gridded in 16 but someone mentioned 128…</p>
<p>There was definitely a rest stop and a post at the beginning of the trail. I’d bet my iPad on it. I remember drawing a picture of the whole thing and explicitly adding those starters. I even drew circles.</p>
<p>The question explicitly points out that there was one of both at the start of the trails.</p>
<p>what were some experimental questions??</p>
<p>Should have gridded in 128 since k HAD to be over 100 and your question asked you to define k.</p>
<p>did anyone get 12pi for the problem with the cone?</p>
<p>I got 12 pi, did anyone get fifty four for f(6)/6</p>
<p>I can’t remember, houstonr. Do you remember any more details?</p>
<p>Ah, almost confused it with that f(6)=6^2-6(6)+9</p>
<p>what was the f(x) for that question?</p>
<p>@eaglesk The answer is 3/2</p>
<p>i got 1.5, i think that’s what most people got. and for the trail problem, it was definitely 2:1. there were markers and rest stops at the start, so in total the markers would be 8 and rest stop 4.</p>
<p>@sunjaym I definitely remember gridding 9/22. I think it was for the sour ball probability or something</p>
<p>@sunjaym, thats what i got. 9/22.</p>
