October 6 SAT math

<p>how i understood the climbing question is:
a certain proportion of the people can swim (which was 40? 60? dont know)
a certain proportion of the peolple can climb.(which was 20)
what is the least number of people that can climb and swim?
logically isn't it 20? becasue that is the least number possible.. </p>

<p>yeah.. i know i probably misunderstood the question..</p>

<p>molldoll825, the answer to that is 1.5 * 9 = 13.5, not 27. Sorry :(</p>

<p>75 was e</p>

<p>10a+15b = 1275</p>

<p>a+b=90</p>

<p>Rectangle was 27/2</p>

<p>so, what was the systems one?</p>

<p>so for the marbles it was A right? the lowest which was like 14 i think...nvm thats not it</p>

<p>what did you guys get on the temperature problem? where there was a chart and asked for greatest temperature difference or something?</p>

<p>The first one, -3 as the slope</p>

<p>temperature - got the first row in the table
anyone got the one where which side of the line L is on?</p>

<p>There was a table chart. Not a graph chart.</p>

<p>damnnn i thought the base went to the second root, which was 3 ughhhh</p>

<p>Wow, that TICKS me off. I typed in the equation on my calculator, and assumed that the two intercepts were 9 and 3. No wonder I thought that was so easy...</p>

<p>240 people were at camp, 5/6 can swim, 1/3 took a climbing class. </p>

<p>so 200 could swim, and 80 people took a climbing class</p>

<p>It asks the least amount of people that could swim who took the climbing class.</p>

<p>the smallest answer choice was 20, but if you have 20 that could swim, then there is 60 leftover who took the class who couldn't swim. This gives a total of 200 who can swim and 60 leftover who can't swim = 260 which doesn't equal the original 240 people at camp.</p>

<p>Next answer choice is 40, if you got 40 that can swim, then 40 who took the class couldn't swim. So 200 who can swim + 40 who can't swim = 240 = the right answer. Answer = 40 (B)</p>

<p>Temperature problem = A</p>

<p>systems one = z = 2 </p>

<p>Can someone tell me whether the math section with the question about</p>

<p>Point P in Plane M, how many circles with center P and circumferience 9pi exist in M</p>

<p>was an experimental section or not?</p>

<p>I, II, and III for intersecting line</p>

<p>JCasey83, choice A was like -3t + 12 , you plug in 9 and 12 and you see that it decreases the most.</p>

<p>the one with point P in plane...i got more than 4....</p>

<p>It asked for the largest decrease..</p>

<p>Circle P was NOT experimental</p>

<p>aww damn thanks. I missed one in math then @#$@ -_-</p>

<p>opqpop , point p was not experimental.</p>

<p>no i dunno
i was stumped on that one too</p>

<p>What was your reasoning for more than 4 able?</p>
