<p>yeah -2 for me too so far…what is that going to be like a 760-770?</p>
<p>also does anyone know how to update the thread w/o pressing refresh every time…it gets pretty annoying</p>
<p>What do yo u mean without pressing refresh, how would u ever reload a page then. Ctrl+F5 also refresh on firefox. And if many people did get the pie chart and f(AB) q’s wrong, we may be in luck. But, lets not get our hopes up…</p>
<p>I did terrible on math… i usually get -2 -3 and sometimes 800s but today i misread a thousand times and like ****… lucky if i broek 680…</p>
<p>For the questions about the water filling up the tank, i’m pretty sure that it was 120 minutes and NOT 160 minutes. Here is why. </p>
<p>You have a small tank with a water level of 200 gal and a large tank with a water level of 900gal, right? The large tank pumps into the small tank at a rate of 2.5 gallons/minute. So, in order to pump 100 gallons, it takes 40 minutes because 100/2.5=40.</p>
<p>So, (increments of 40 minutes)
0 min= 200 gal, 900 gal(starting)
40min = 300 gal, 800 gal
80min = 400 gal, 700 gal
120 min= 500 gal, 600 gal******** < answer IS 120 minutes!!! not 160!!</p>
<p>160 is for them to equal 120 is when it’s 100 more than the other and thus 120 is the answer…</p>
<p>Would you say the March math was easier or harder than the January math?</p>
<p>can someone explain what the 4root 2 problem was?
and how to do the p% and x% question? thanks</p>
<p>oh my gosh
yea ugh
i hate the SAT
i already got the f(ab) wrong due to overthinking and i am pretty sure i got the tank one wrong because i forgot about them having to be 100 apart
■■■</p>
<p>Can anyone else confirm that 120min was the answer?</p>
<p>yes i confirm it’s simple do it yourself 900-2.5<em>120=600 200+2.5</em>120 =500 if i remember the question correctly.</p>
<p>it was asking when tank A was 100 less than tank B, not the other way around. </p>
<p>so it is 160.</p>
<p>yeah, delian’s right. the answer was 160.</p>
<p>Are you guys sure it wasn’t 900 and 100? I have this nagging feeling that it was 100… I dunno.</p>
<p>awww? are you sure? =[
darn it, these problems are too tricky. I probably read that question too fast.</p>
<p>i’m 100% it was 900 and 200
it’s still in there from my calculator</p>
<p>oh right delian… i knew i did 600 for a reason… i needa stop second-thinking myself…</p>
<p>it’s 160 no question</p>
<p>yeah, i got 120 at first then realized i had switched the tanks so changed it with 2 sec left in the section lol. close shave.</p>
<p>yea
it’s 160
i got 140 minutes for when they were equal
because i forgot about the 100
so yes, it is 160.</p>
<p>darn darn darn =[ =[ =[
sheeshh
-1 for me
blah</p>
<p>oh and the questions with the square in teh circle was definately pi!!
because the sides of the square are rad2, and there is a 45, 45, 90 triangle, so the two sides are 1(which is the radius) so piR^2=pi</p>
