<p>its 20 dude give it up.</p>
<p>it BETTER be 20, or I'm go cry lol</p>
<p>mtf612: 24 is out of the question lol if it was 24, then it would be a rectangle instead of a trapezoid</p>
<p>i put 24, and i was 100 percent sure why...but now i cant remember lol. Someone have a diagram or something...?</p>
<p>some-dude, it's 20. if you divide the trapezoid into three triangles, you'll see that the outer two are equilateral without question. that would also make the inner one equilateral, since you'll have 60 degrees for one angle and its adjacent sides both 4. and thus, you have the top part (or one leg of the triangle) equal to 4.</p>
<p>why are u guys still arguing?!
ITS 20!!!! CASE CLOSED!!
it was 3 circles , then u connect dots. 24 is so ridiculous, not to mention that the bottom base is only like what 8? and u expect the top to be 8?? u have some problems .</p>
<p>Alright, I stand corrected.</p>
<p>The ONLY question that i couldnt do on teh math section was 2/x > 3, because i am lazy as hell and i solve all equations on my ti89 and i spent 2min going thru the catalog looking for the '>' key and finally i entered it and it gave me 0>x>2/3, which wasnt an answer. could someone actually explain how u get the actual answer??? thank you!</p>
<p>^i had trouble with that too, then i ended up plugging in numbers, like .2 ~ .8 whatever, took me a good 1 min i think, i dont remember the answer.</p>
<p>^ It seems that the most efficient way to do it if you are fast with a calculator is to plug in. The answer was .25<x<.5. if="" you="" plug="" .26="" in="" for="" x="" and="" .49="" (2="" x)="">3, they both work.</x<.5.></p>
<p>oh my gosh, why are we arguing about an E level problem?</p>
<p>2/X<3?</p>
<p>JUST PLUG IN</p>
<p>someone remember how the graphs for the elevator thing look like?</p>
<p>Or graph the function on your calculator and look at the domain ranges you're given to see which one is all above y = 3 (you can graph that as well).</p>
<p>^ luckily, I do.</p>
<p>up 20, level off for an amount of secs, level down 10, level off for some amount, up 30, level off for some amount, and then str8 down. At t=120, it was 20 down from the last time where it was up 30.
So, total = 80 (20 + 10 +30 +20). and it levelled off 3 time sbefore t=140 (which was before the end of the graph).</p>
<p>did it stop 3 or 4 times?</p>
<p>and what did you guys get for the clay problem. i got 4. can someone refresh my memory and tell me the exact numbers?</p>
<p>thanks</p>
<p>@WantIvy, I think the general consensus is that this SAT math is easier or at least the same as usual. -1 for an 800 on math is typically harder than norm math, which was the case of the October 2006.</p>
<p>where's quix today -.-</p>
<p>How could 2/x > 3 be hard? You can eliminate 3 of the answers by common sense.</p>
<p>if X is negative, then the function would be negative.
So you had the 1/4<X<1/2 and some other one.</p>
<h2>and just plug in o_o</h2>
<p>Ren, Quix's been banned.</p>
<h2>he told me on aim</h2>
<p>the elevator stops 3 times.
If you have calculus, you should know it stops when f'(x) is 0.</p>
<p>ironically its the only question i missed in the whole mathematics portion of the sat. xD. seriously tho because if u set 2/x =3 to find critical values u get a critical value of 2/3 and see that values smaller than 2/3 for x make 2/x > 3 like the problem stipulates. so why is it not 0<x<2/3?? didnt the problem say which is the range of x values that satisfies the inequality??</p>
<p>yea 1/4<x<1/2 is a valid range but it is not the whole range, which is x|(0,2/3). i believe the problem asked for hte whole range and since i never use testtaking strategy on the math probs i just freaked.</p>
<p>why's he banned lol...i wanna hear from him, where's kho?!!</p>
