<p>Wouldn't it be positive 7/25 since it's in quad 2? Sin in quad 2 is positive. Does anyone remember what the answer to the second to last question in math was. It was about the pairs of numbers that add up to 5 and had something to do with 64. The choices were 0, 2, 4, 8, and infinite I think.</p>
<p>sin is positive in quad II so the answer was 7/25 not -7/25</p>
<p>Really???</p>
<p>I put that and I thought I got it wrong.</p>
<p>and twins, i thought it was 2</p>
<p>I put 2 too
is that right?</p>
<p>since it was radius, it was half of the diameter (corner to opposite corner), which was sqrt(16+32)</p>
<p>for science, are they supposed to/allowed to put questions that require prior knowledge?</p>
<p>well the only solutions were 3,2 and 2,3. 1,4 and 4,1 dont work</p>

<p>I used a completely different way and I found that diameter to be 2sqrt3. I tried looking for the answer (as a radius) by dividing the diameter in 2 but it wasn''t available so I panicked and guessed correctly :)</p>
<p>That makes sense, I was almost out of time by that question and didn't have time to completely think it through. Thankfully, I switched my answer from four to two.</p>
<p>I got the diameter of the cube to be 2sqrt of 3 too, and was looking for the square root of three in the answers. I still don't get how that one worked exactly.</p>
<p>I agree. The questions about radiation, cell membrane, and Saturn all required prior science knowledge.</p>
<p>What did everyone do for the writing? did we all have the same prompt- Whether television channels should have 20% of their programs dedicated to educational programming. What some arguments you made for/against it?</p>
<p>yea but if you guys think about it, those three questions were some of the easiest ones in that section.</p>
<p>The ACT openly says that it tests on knowledge--especially that learned in class. I think they were fair questions. It's common knowledge that Saturn is massive and cells have membranes.</p>
<p>my basic science is terrible; I can't remember that saturn is the biggest from 3rd grade, and for the convection one, I didn't read it right, I assumed since they were talking about the transfer of energy in the bars</p>
<p>wait so radiation was correct?</p>
<p>I put only conduction</p>
<p>How much would nine wrong in both math and science be</p>
<p>Wouldn't it be only conduction because the heat is traveling through a solid metal bar?</p>
<p>wait what was the answer to that one? was it conduction or radiation and convection</p>
