<p>padres13, are you talking about the question where you were supposed to use the law of sines? (A/sin(a) = B/sin(b) = C/sin(c)) Just curious. I didn't calculate any of the answers and I don't remember the answer so I don't know if you got lucky ;)</p>
<p>i think that was the one you had to use the law of sines for..do you remember the angles it gave? if so, i can figure it out</p>
<p>on the isoleces traingle one, waht did everyone get for side lenths. i think i settled on 4,4, 9</p>
<p>You can't have a isosceles triangle with 2 sides adding up to less than the 3rd. I don't remember which one I chose, but I do remember it was the only one in which the sum of the 2 equal sides was greater than the length of the long side.</p>
<p>Just think...the angle between the 4 and 4 sides must be less than 180. Even if it was 180, the total length would be 8 (less than 9). The other options were like 5,5,11...2,2,4...and then I chose one that was like 3,3,5 (or something in which the sum was less than the large side)</p>
<p>jlamp it was 2,2,3.. but you got the right idea</p>
<p>for the venn diagram one i put B the top right, with had like some #, 7, and 6 in the circles respectively... dunno tho</p>
<p>WAIT..haha yes! i remember going back and changing it because i had gotten the rule backwards. i thought at first that the two smaller sides had to be less than the third side but when i went back to check answers i realized that held true for several of the other options as well.</p>
<p>Science question.. greatest per unit time.</p>
<p>Couldn't have been 2 p.m. because the 4 a.m. slope was the steepest. So the greatest change in altitude per unit time was at 4 a.m.</p>
<p>Think about it in terms of slope... a slope of 4/1 (steep) is greater than 4/4 (less of an incline).</p>
<p>If someone could explain how it was 2 p.m. I'd like to know because that doesn't make any sense to me.</p>
<p>do u remember more specific wording of the question?</p>
<p>i remember now..it asked which time had the greatest drop in temperature per unit time. i think 4 am actually increased temperature..didnt it?</p>
<p>wait, so it was 2 p.m? if so then i totally lucked out since i guessed on that question :)</p>
<p>If it did ask for the greatest drop, it still wasn't 2 p.m.</p>
<p>In fact it may have been the greatest drop.. that means it would have been one of the other times...</p>
<p>check out page 6 and 8, several other people said 2 pm though i think people are remembering the question differently</p>
<p>what was the question? im gettin confused by what other people have been putting</p>
<p>were the sand grains ground up because they were too big to fit or soemthing like that?</p>
<p>i said they needed to be ground up so light could pass through. in the passage it referred to a certain type of light used when determining the type of sand so i just answered quick and went on</p>
<p>didn't it have something to do with the thickness?</p>
<p>wait on the graph was the 2 pm one the steepest?</p>
<p>==</p>
<p>didn't it have something to do with the thickness?</p>
<p>==</p>
<p>I think I put this option. </p>
<p>Did this option have something to do with light?</p>
<p>yes..had to do wiht the thickness...if the sand was too thick the light couldnt pass through. thats the connectioni made at least. on the graph, 2pm was the least steep and furthest to the right i think. all the graphs came to the same point. 4 am was the steepest. thats my best recollection</p>
<p>oh</p>
<p>in that case</p>
<p>2 pm is the correct answer.</p>
