December 2013 SAT thread

<p>@DonCorleone37 I had reading comps about fishing, meteorites, dying languages, and children using computers</p>

<p>i forget the others…but definite not about a duck or whatever</p>

<p>pi is the correct answer
pi means that the radius of the small circle was 1 (pir^2)
The diameter of the large circle is 6x the radius of the small one…so 6*1/2 is the radius of the large circle aka 3
3^2pi is the total area of the large circle and subtract the pi from the small circle to obtain 8pi as given</p>

<p>y is directly porpotional to the square of x, and if z is inversly porportional to y z is invesly porportional to what y is directly porportional to…the square of x</p>

<p>idr the 986 problem anyone wanna fill me in?</p>

<p>haha sorry just panicked…what was the mole question though? I forget</p>

<p>chem was EXPERIMENTAL…no use talking about it guys haha</p>

<p>Were you talking about that special prime number grid in? The answer was 995.</p>

<p>Oh yes you’re right, I put pi to. Ok. There is no 986 problem I think it was a mistake on somebody’s part.</p>

<p>@1Momof3 </p>

<p>Yeah so you had a different test version as my reading comps were about: the Sphinx, higher education and some Pakistani immigrants or sth </p>

<p>Anybody apart from SatVictim had this weird section on CR (illusion, art, and an ambiguous picture of both a rabbit and a duck)?</p>

<p>@dmj sorry i was thinking of one of the grid-in questions for 986 one. It was asking the the largest 3-digit number that the sum of its digits are prime.</p>

<p>Yes the “digial prime” is 995, easy. The mole question was like question 3 on experimental math asking like, how many moles are in 3.09 * 10^-19 ← something like that and you just divide or something.</p>

<p>I got two no errors and so the answer was inversely to the square of x?</p>

<p>Is this for the us version??</p>

<p>@Lanie49 Yes that’s the answer.</p>

<p>yeap inverse proporp to the square of x. I rememer i answered it quickly though and i hope i didn’t accidentally put x^2 if that was even an option</p>

<p>im pretty sure z was inversely proportional to the SQUARE of x</p>

<p>995, my bad</p>

<p>@santaman I didnt actually have that mole question, do experimental section have different questions in them?</p>

<p>Who had the back to back double long paragraph CR section 2 and 3? I’m pretty sure section 3 was the experimental one.</p>

<p>@1Momof3 Did you have a experimental math section? The one with the mole was a math experimental GRID-IN section, you may have had an experimental math section for multiple choice only.</p>

<p>wait for CR what was the answer for the galvanize, ameriolate one?</p>

<p>@xxSATxx the sqaure of x.</p>
