<p>I got 65 on that one. That was one of the hardest problems for me though, so I'm not 100% positive.</p>
<p>For the mirror one, I got 85 degrees. I just ballparked it, since everything is drawn to scale on the act.</p>
<p>for the garden one...i didnt have time so i just did G, B, G or B, G, B...anyone know if one of those is right?</p>
<p>i also remember a science question having the answer 102˚F-104˚F, does this sound right?</p>
<p>yeap, 102-104. was there an option for 104-106?</p>
<p>The mirror one was definitely 70 degrees. You just had to use the fact that the angle of incidence equals the angle of reflection and work your way around the angles using basic identities.</p>
<p>Wow, guys, I am surprised you still remember the questions and even answer choices. :)</p>
<p>Oh, I'm pretty sure Diane was the mother of Ola, too.</p>
<p>what about the mirror one? I think I got 50</p>
<p>to bring back up the one about density, mass and volume, due to the equation density = mass/volume, if one of the things on the right side changes, then the density changes. However I think I said that all 3 change but maybe just that the volume and density change. I believe the answer is that all 3 change because: as temp decreases below 0 and water becomes ice, it definitely becomes less dense and more voluminous and somehow the mass must be changed too because of the phase change. God I hope I'm right</p>
<p>Edit: wait, I might be messing this up if we consider the conservation of mass law. I can't remember much from chem.</p>
<p>Amount of mass does not ever change.</p>
<p>Law of Conservation of Mass: the mass of a closed system will remain constant, regardless of the processes acting inside the system</p>
<p>the answer was volume and density.. if volume changes, then density does too (density = mass divided by volume)... mass will not change (unless you physically take some away.. and that wasn't done)</p>
<p>so the answer was I and III (density and volume)</p>
<p>^I didn't read the question and guessed that lol</p>
<p>i got 70 for the mirror problem too... i'm pretty confident about that... we've done a lot of those problems in our AP physics class, and i've gotten those problems down.. i'm pretty confident it's 70</p>
<p>and for one of the last ones (56 i think.. the one with the y=ax+2 going through the cube)... was a 2/3?</p>
<p>yeah the one with the square going through the coordinate plane</p>
<p>i got 2/3's too</p>
<p>i got 2/3 also...i had no clue what i was doing. all i did was found the middle x value of the rectangle (if that makes sense) and multiplied it by the answer choices. the only clean answer i got was with 2/3</p>
<p>on the reading passage I... what was the answer to the one about what occurred between Martha and (either Ola or the narrator).. i put the one about it was a friendly exchange and more music was made (i can't remember exactly what the question stated)</p>
<p>I'm pretty sure the mirror problem was 70, the science question was between 102-104, and the first two garden questions were 47 and 150 (not sure which one was first though).</p>
<p>in english--the photographer passage, it talked about how the guy had taken pictures of historical figures then went on to talk about how he took pictures of famous singers....did you choose "HOWEVER, his photographs of.." or just "HIS photographs of..."
(that's all i remember about it, sorry)</p>
<p>and peytoncline do you happen to remember what letter choice volume and density was on science?</p>
<p>i just put "his" because the writer wasn't trying to make a contrast</p>
