<p>i am astonished that you guy still remember the ANSWER CHOICE LETTERS for these questions. i remember the correct answers, but i don’t think i could remember any of the answer choice letters even right after i walked out of the testing center.</p>
<p>Anybody know what would a -9/10 on MC and a -3 on the student grid be?</p>
<p>Thanks.</p>
<p>Please Jesus, let me have bubbled in all the grid ins…please.</p>
<p>^ Don’t worry about it. Two years ago when I took the PSAT, I thought I hadn’t gridded in the math problems. Turns out I did and got them all right. Relax.</p>
<p>If I bubbled in wrong or missed easy questions, I would be really sad.</p>
<p>mikefos, thats about 610-630.</p>
<p>indianjatt, if u just bubbled wrong on grid ins, u can get it hand scored if need be</p>
<p>No, you can’t. That’s a test taker error which they will NOT give you points.</p>
<p>are you serious?</p>
<p>if you wrote “196” clearly but bubbled in 195 by accident, they don’t give points? what the hell? that’s odd</p>
<p>If they did that, then if I wasn’t sure between “2” and “3,” I would fill in “2” in bubbles but write “3” clearly. A guaranteed correct answer! :)</p>
<p>oh wow i’m dumb. true. haha</p>
<p>for the surface area of a rect solid one</p>
<p>were all of the choices in units squared?
or inches squared?</p>
<p>like the aenswer was 62x^2 right</p>
<p>I just looked for 62
someone told me there mightve been a 62x also</p>
<p>I just remember the answer i put (62X^) was choice D and directly underneath 60X^ which was choice C</p>
<p>also, what about the one with 1000 integers i did it some weird way cus i figured </p>
<p>theres 33 between 1-100
but 200s, 500s, 800s have both endpoints as multiples</p>
<p>201, 501, 300, 600, etc</p>
<p>so i put 663</p>
<p>and the parabola one was 2k-a right</p>
<p>I think the question asked, what is the surface area in inches squared but the answer choices had no units. The answers were something like</p>
<p>30x^2
30x^3
60x^2
62x^2
forgot the last one</p>
<p>For the 1000 integers, you had to know that the question was asking positive integers less than 1000 that are NOT divisible by 3. So we’re dealing with 999 numbers. One way to do this is to divide 999 by 3, which gives the number of multiples (those divisible) of 3, or 333. Those not divisible by 3 are 999-333 = 666.</p>
<p>parabola one was something like that.</p>
<p>was 62x^2 choice D?</p>
<p>C od D, really doesnt matter</p>
<p>jamesford is right yet again… surprise surprise…</p>
<p>and yes, the parabola question was 2k-a</p>
<p>the surface area one’s answer 62x^2 are we positive that that was choice D, because someone earlier said that was choice B, and it was a 16 question section and for some reason I filled in question 17 for B and 16 for D, now I’m worried I screwed up that whole section…</p>
<p>How to solve the sat math problem whereiun it asks for a surface area of a prism or something, do you have to use 2lw + 2wh + 2lh to find answer since there is no unit… also how about the 3 circle thing wherein the unit is pi, its located on last part of sat section, did anybody answered this 2 hard questions? thanks!</p>
<p>Can someone explain the “divisible by 3 under 1000” question?</p>
<p>The way I did it is:
3 numbers divisible by 3 in each 10 numbers.
3 x 100 = 300</p>
<ul>
<li><p>all the tens that are divisible by 3 (30, 60, and 90) in each 100.
So 3 x 10 = 30</p></li>
<li><p>all the hundreds that are divisible by 3 (300, 600, 900) in the whole thousand.
So 3 x 1 = 3</p></li>
</ul>
<p>= 333</p>
<p>and then 999-333=666</p>
<p>I don’t understand how people can go directly to 999-999/3 = 666
Can someone explain the logic behind this calculation?</p>
<p>It seems that you just dont have any imagination. It’s very simple, every third number is divisible by 3. Since 999 is divisible by 3, you immediately know, that 2/3 of numbers smaller than 999 are not divisible. It’s like how many numbers under 101 are divisible by 5.</p>
<p>Don’t really understand why it means I don’t have any imagination, in fact I find that comment slightly insulting, but thanks anyways. I understand it now.</p>
<p>–</p>
<p>Hey! Also every xth number is divisible by x. Cool!
Feel like an idiot now. Still doesn’t mean I haven’t got imagination lol.</p>
