<p>The answer was 19, namely because the ratio was 1:19</p>
<p>19x 19= 361 You then add the original 19 to get 380, which was the total they gave you.</p>
<p>Sorry you got it wrong I hate that feeling.</p>
<p>Ohh I see. Darn it.</p>
<p>How about my question on post #827?</p>
<p>@joewii i dont remember that question. do you remember what it asked? for your other question that would prob be a 790 but it depends on the curve</p>
<p>3x=6- 17</p>
<p>Does anyone remember what this was the answer for???</p>
<p>no, the answer is 17. 3x=6 was part of the problem.</p>
<p>do u remember which question this was??</p>
<p>Please answer, I have had this stuck in my mind:
Does anyone remember all five answers to the PQRS problem?</p>
<p>IT IS DRIVING ME CRAZY!!!</p>
<p>The wire problem: 4c2 (4 choose 2) is six. There are only six possible pairings of wires if the order of the pair is disregarded. You have: 1-2, 1-3, 1-4, 2-3, 2-4, 3-4. All other possible pairings are the SAME wires in different orders (i.e., 1-3 = 3-1).<br>
The answer is absolutely 6.</p>
<p>The intersecting parabola problem: The first step was to recognize that you had to set the two equations equal to each other, that is, say that h-x^2=x^2. Using simple algebra, you can manipulate that equation to form this one: h/2=x^2. The possible answers given were all TWICE a PERFECT SQUARE (18=2(3^2), 32=2(4^2), etc.), except for 12. Half of 12 is 6, and root 6 is irrational. Therefore, the answer was 12. </p>
<p>I am a thousand percent positive.</p>
<p>as for the question with the sphere, it did not specify “line segment” but it asked for the distance between the two points, not the distance between the two points ALONG THE SURFACE of the sphere. for that reason, it was the line segment (and the answer was 6)</p>
<p>it’s definitely 6 for the sphere question and even if it was a distance along the surface of the sphere, everyone who put 9.42 would be wrong because the longest distance wouldn’t have been half the circumference, the two points could have been so close to each other that the longest distance would be something a little bit shorter than the entire circumference</p>
<p>actually it did specify ‘line segment’</p>
<p>but when in doubt, ALWAYS answer the question exactly; collegeboard NEVER asks for an answer that will not fit into the grid. never ever round unless the question asks you to.</p>
<p>@akkisonology, if the question did ask for the longest distance along the surface of the sphere, 6pi would be right because if you move the two points from the ends of the diameter, one arc will lengthen but another will shorten depending on which way you look at it.</p>
<p>I cannot believe I did not get the quadratic one. thx JrStudent1110 it makes sense now.</p>

<p>can someone please tell me what the choices to the cal wed logic question were?
was there another option with wed? or another option with calc? was it possible to eliminate directly by thinking on 2 different roads and end up leavin one option? the answer was not the first or last option but i cant remember which one i put in exactly :S</p>
<p>3x=6- 17</p>
<p>Was this the first grid in? and did it have an absolute sign in it if anyone remembers?</p>
<p>no, it was the first MC question to a section… you probably got it right.</p>
<p>ok… did the first grid in have a absolute sign and asked for one possible value of x?</p>
