Math for March SAT 2009

<p>is there any chance that -1 on the math will be readjusted to 800?? =/</p>

<p>no, there’s no chance</p>

<p>shucks =[…</p>

<p>It’s happened in the past, but rarely…</p>

<p>maybe if they gave a limit question lol in which epilson-delta proofs were the choices and asked which of the following proofs is equal/proofs the limit stated lol</p>

<p>and trust me, i’m not happy to say that - I usually get 800’s on the math, but I already know that I misread a question</p>

<p>pshhh i wishh they would put calculus related questions on there
like a problem related to estimating the area under a graph(totally do-able with algebra reasoning), but 90000x easier with integration.</p>

<p>To Bob.Dylan., thanks yeah that’s what I put, but I used some insanely complicated math and I cannot believe I didn’t just do what you’re saying…I had all of this nastiness with x’s, y’s, z’s, and a’s, and when all was said and done I had (40/3)x + (40/3)y = ax +ay, and I was solving for a. But it took a WHILE. I finished the whole section though.</p>

<p>lol with that question with the two triangles on that line where the answer was 40/3 you could’ve just done one proportion and gotten that answer</p>

<p>given: area of triangle 1= 3, distance=10
area of triangle 2= 4, distance =x
so, 3/10=4/x, and 3x=40!!! yay! one step solution</p>

<p>I used a proportion as well.</p>

<p>i asked about the 5/12 question, but also what was the question people are mentioning about a-5 or something, sounds familiar</p>

<p>I have a question…</p>

<p>If I missed one MC and open ended, are the points deducted from both the same? Or is one worth more than the other?</p>

<p>Same, because they round to the same raw score.</p>

<p>The 5/12 one was something to the extent of
4x-5=0, 3y-9=0, what is x/y? (Note: I may have misremembered the numbers, but this was the question)</p>

<p>maybe I missed somthing…but I got 141 for the answer</p>

<p>900 - (2.5)x(141) =547.5
200 + (2.5)x(141) = 552.5</p>

<p>wasn’t the question when the second tank(200 one) starts to have larger amount of water than the fist tank(900 one)?</p>

<p>maybe I missed somthing…but I got 141 for the answer</p>

<p>900 - (2.5)x(141) =547.5
200 + (2.5)x(141) = 552.5</p>

<p>wasn’t the question when the second tank(200 one) starts to have larger amount of water than the fist tank(900 one)?</p>

<p>^ close, but it was when 2nd tank had 100ml more water than the 1st one … or something like that, but it wasn’t just when the 2nd had more water than the 1st.</p>

<p>I just looked at collegeboard and I realized that my math experimental section (my second grid-in section) is the one I completely messed up on. I’m so relieved!</p>

<p>the 2p<x<3p problem also could include 35 as an answer right???</p>

<p>because 13<em>2 and 13</em>3-----> 26<35<39</p>

<p>please tell me if I am wrong</p>

<p>not true it could be 35 as well as demonstrated:</p>

<p>2(13)<35<3(13)</p>
