<p>can someone please explain the temperature problem? I honestly don't remember that problem...</p>
<p>why cudnt it be where x=0 for the that graph one</p>
<p>One last question: what was the question for the second to last grid-in [answer: 63]?</p>
<p>i probably said x>0 i think</p>
<p>ya i think so..but wut was that question again?</p>
<p>im confused about how people are getting 256 for the student produced response question about the circle with circumference of 8pi. c= 2pi x r, so r = 8. 8x8 = 64?</p>
<p>Pahreen, </p>
<p>it said a number added to nine less than twice that number resulted in 180. What was the number?</p>
<p>r = 8 so the whole side is 16... 16^2=256</p>
<p>shapeofhome, the circumference was 16pi not 8pi. so diameter = 16, which is also equal to a side of the square.</p>
<p>Area of square = side ^2 = 16^2 = 256</p>
<p>If r =8 the side of the square is 16, because a radius is only half of a side</p>
<p>On the student responses, I remember entering 2,63,256, and 13.5. The others are a blur.</p>
<p>O yeah. I put 105 for one. I rounded up. Anyone remember a 105 or 104?</p>
<p>u had to round? i didnt have to round for any of the problems.</p>
<p>could the abc be 9? I don't remember.</p>
<p>i believe 6, 9, 12 are all valid responses to the abc one</p>
<p>I had .2 for one of the student responses. i can't remember what question it was though.. anyone had the same answer?</p>
<p>yeah .2 or 1/5 was teh correct answer</p>
<p>which free response had an answer of 4. actually, can someone just post the questions in order, and then the answerS?</p>
<p>Ya that was just the first one where x/10 = 10, and they asked what 20/x was.</p>
<p>hey i got 4 on one of the free reponses but i forgot what the question was</p>
