Math for March SAT 2009

<p>Math was dece, I guess,probably made a mistake or two. Writing was a bit more difficult… + I screwed up on the essay (5 minute warning called when I was only on the second body paragraph)…and Reading was a disaster,I guessed so many…I guess it just takes practice,that’s how got really good at math,so May SAT,here I come!!</p>

<p>Anyone here taking April’s ACT…I hope I POWN that,so that I can put it aside and never have to think about it again… just wanna focus on school yo,</p>

<p>yeah, a lot of people probably got the circle one wrong. it asked that p<2x<3p except everything was in a PIE CHART, meaning percentages, not angle measures. 49 was an answer, as well as other 40s numbers</p>

<p>i think i got like 4 wrong on math and omitted 2… so 680 ~ -.-"</p>

<p>f(ab) = f(a)+f(b)</p>

<p>f(16) = 24</p>

<p>^ thanks for putting up the RIGHT answer, lol!</p>

<p>could someone explain the f(ab) question and how to go about it… </p>

<p>I remember how this cuz i stared at this problem with my remaining 5 minutes after completing the rest of the section and i could not get any sense of logic of how to go about this problem…</p>

<p>f(2) = 6
f(16) = f(2x2x2x2) = 6 x 4 =24</p>

<p>Anything from 41 to 49 would have worked. Not sure if it wanted integers though. </p>

<p>I had a major brainfreeze today, and didn’t get that one >.></p>

<p>My last question for experimental was awful haha.</p>

<p>Was like A is all numbers 1 to 100 inclusive and a number x. T is all numbers in A but with the condition that the median of these numbers is the same as the mean. What is one possible value of x. </p>

<p>I had like 2 minutes left, when I got to it</p>

<p>I got 45 for that one, each number has the same amount of numbers as it’s tens digit.</p>

<p>10 - 10, 11
20 - 20, 21, 22
30 - 30 31, 32, 33
ect.</p>

<p>It looks like I got it wrong though…</p>

<p>

</p>

<p>Can we say the exact question?
I’m sure the answer was 5 not 3, not sure if I’m allowed to explain why.</p>

<p>basically, anything where p was like 17, 18, 19 i think. i put 19</p>

<p>ice, 3 wasn’t divisible by the resulting number, lowest was 5</p>

<p>JML i don’t recognize your problem at all, experimental perhaps?</p>

<p>Prime = 5
SOdas and ICe cream = 3.50 for me
I never had the sequence one… so experimental?</p>

<p>new fish - the cylinder one was experimental from what i gather. but i think answer was 3/8 of 24.</p>

<p>

</p>

<p>Here are all the possibilities:</p>

<p>17: 34 < 49 < 51
18: 36 < 46 < 54
19: 38 < 43 < 57</p>

<p>16 was too low. P would be higher than 3x. and 20 has 2x = p. So no go.</p>

<p>

</p>

<p>Wouldn’t work. The first digit had to be larger than the second.</p>

<p>For the pie chart with p and x, are you sure anything between 41 to 49 will work? I put 42, but i think the percentage has to add up to 100? Correct me if i’m wrong.</p>

<p>yes we are the embargo has been liftedd</p>

<p>yeah i never had that one dagol</p>

<p>did anyone get something like 40/(a number i cant remember), for the non-multiple choice problems? it was a fraction so some might not have rounded, but it seemed odd to me. can’t remember thee problem though</p>

<p>monoclide, unfortunately i’m not following you with the x and p and the pie chart … so what values could x have been?</p>

<p>

</p>

<p>Anything between 41 to 49 will work. But won’t run smoothly - there will be decimals. 43, 46, and 49 are the ones that run smoothly.</p>

<p>(What they are going to accept, different story.)</p>

<p>

</p>

<p>Ah, sorry about that. Maybe this will help:</p>

<p>x=17: 34 (2x) < 49 (100-3x) < 51 (3x)
x=18: 36 (2x) < 46 (100-3x) < 54 (3x)
x=19: 38 (2x) < 43 (100-3x) < 57 (3x)</p>

<p>was it sayign f(a)+f(b))=f(ab) or what did it say… i still don’t exactly get that question.</p>

<p>Was 65 for the polygon choice A?
And yea, 36 or something for 10’s digit less then 1’s digit.</p>

<p>40/3 yesss</p>
