<p>The long diagonal of the cube is s*rt(3); that equals the diameter of the sphere.</p>
<p>To find the radius, you must divide that by two.</p>
<p>For the cube and sphere i got (s rad 2) / 2</p>
<p>yeah that was it iostream, im just ■■■■■■■■. so was it 2root3/2? Do u remember it that answer was E?</p>
<p>Wow iostream, BC as a sophmore, impressive.</p>
<p>can someone explain the cone problem plz</p>
<p>hey guys, plz post more of your answers that you stilled remember</p>
<p>Does anyone remember the answer to the logic problem.</p>
<p>i got s sq rt (2)/2 as well. I said it was sq rt of ((.5s)^2 + (.5s)^2)</p>
<p>the cone problem I had narrowed down to two and then plugged in 4.8 and it worked. I can’t really remember it</p>
<p>the logic problem was the stupidest thing I have ever seen, i was totally stumped. However, i did put that t>3 because the original said that 3>t. I may be wrong, but i have no clue on how to approach logic problems.</p>
<p>I said >=3 because if it was false then it could have also been to =3 as that never satisfied the original statement.</p>
<p>“Does anyone remember the answer to the logic problem.”</p>
<p>I can’t remember the specifics, but from what I recall this is what it was like:</p>
<p>All vacationers are tourists. Thus: If x, then y. (if you are a vacationer, then you are a tourist).</p>
<p>The correctly derived statement would be: You are not a tourist, therefore you are not a vacationer. ~y, thus ~x (because of modus tollens, or proof by contrapositive, if I remember the terms correctly).</p>
<p>EDIT: Did i conflate the actual question with something from a practice test?</p>
<p>EDIT 2: For the T<3 problem. If x, then y is true. Y is false, thus X is false (see above for another take on it).</p>
<p>The negation of T<3 is T>=3.</p>
<p>I think it was the opposite so 3>=t</p>
<p>don’t think i had your test general rak…</p>
<p>New request: can someone please post the cone problem itself?</p>
<p>look at p.3</p>
<p>i posted the ansewrs to be (D) x = y or t = 0</p>
<p>yes it was opposite of for the t problem. and the diagonal problem was (s root 2)/2</p>
<p>I put E for the cone question. This was based on the assumption that the Choice/6*3 gets you the radius at that height, which it may or may not actually do. :P</p>
<p>was the answer to the possible order of 8 cars (red first green last) 6!</p>
<p>what was the prime number problem??</p>
<p>yes it was 6!</p>
