December SAT: Math

<p>Can one of u math geniuses do a cumulative of what u believe ur answers to be</p>

<p>also there was one about where is the mode lower than the average. it was an mc on the section not with the grid ins, i think.</p>

<p>what was the one with the random numbers, like 1< 10y< 38.6 and 3<2z<5432758934 or whatever they were. i think the question asked what could be the largest value of x when xyz = 80.</p>

<p>i think that one was a grid in. what was the answer? i got 1600.</p>

<p>I know this is a stupid question but was the pot and picture frame question answer 1 dollar?</p>

<p>@jsmith: I got 24...</p>

<p>andreeaaaa.. thats correct.. i got 1600 too!</p>

<p>1600 is the answer andreaaaaaaa</p>

<p>@andreaaaaa:me too.</p>

<p>24 is not even a perfect square.... how did u arrive at that?</p>

<p>whoooooo good. i was afraid of missing that one.</p>

<p>10/3, anybody?</p>

<p>Thats jsmith, I remember it exactly now. Thanks.</p>

<p>i got 3.33 as that one answer where y is 1 more than x.. but i might have absentmindedly bubbled in 1.33 ......................please god.</p>

<p>well, the problem was (x-3)^2 =25, i think.</p>

<p>and so x2-6x+9=25 , subtract and you get x2-6x-16, I think.</p>

<p>then I arrived at 24 for the second equation.. which I don't remember.</p>

<p>but likely I did something wrong.</p>

<p>one of my experience in doing grin=in question. Always put in the fraction lest it doesn't fit.</p>

llewis999... it said... (x-3)^2 = 25.... the two numbers u could try are 8 and -2....</p>

<p>it asked for (x-4)^2... and what does it equal... i tried using 8.. but the answer was 16 and it wasnt in the answer choices.. so i used (-2).. and i got (-6)^2... which = 36!</p>

<p>hope that helps

<p>yeah i got 36. i am almost certain that was right.</p>

<p>ooooooh.. thats not good keanefan</p>

<p>It's 36. Some advice to all: Buy a TI-89.</p>

<p>It can solve any equation you put into it. For the 36 one, I just had to type it in (takes 5 sec), use the values of x given (8, -2) then I do those calculations.</p>

<p>what other ones can we hit.</p>

<p>ahh... darn.</p>

<p>it makes sense now that I look at it... =[ <em>sob</em></p>

<p>so was 12 a grid in answer.</p>

<p>i think i got that for adding the 27 terms together.</p>

<p>and what about 8. was that a grid in answer?</p>
