<p>it was the urban intellectual one for sure, too. gj!</p>
<p>@anonito- thank you! :D</p>
<p>So this is how you do the rings without brute force:
(Note that for this explanation I will use the mod operator, basically it just means that it returns the remainder of the division, so for example 5%2 , % being the mod operator, returns 1, because the remainder of 5/2 is 1.)</p>
<p>You start off with the pattern rbggyp (or something along those lines, the only thing that matters is the position of r and b). Label the rings 1-6 left to right</p>
<p>Note that position%6 tells you which ring is at a certain spot. For example, if you want to know what ring is at the 1st spot, then 1%6 returns 1, which means that ring r is at the 1st spot. This continues until 6%6 returns 0.</p>
<p>Since 16%6 = 4, you know that after you remove the rings, b is at the 4th position in the pattern. Shift it over left until you get b to be in the 4th position. You know have this:</p>
<p>yprbgg.</p>
<p>Now, doing 51%6 returns 3, which points to red, which is the answer.</p>
<p>what did u guys get for the biggest ratio i think… the question said a point is on a cirlcle and they said AB was a dimaeter and asked the biggest ratio i thnk</p>
<p>Biggest ratio: The trick was to notice that line segment AB had to be perpendicular to the diameter for the area to be maximized, because otherwise the height would be less than the radius.</p>
<p>Area of triangle:height*length/2
height = line sigment AB = r
length = diameter = 2r</p>
<p>Area of triangle = (2r^2)/2 = r^2
area of circle = (pi)r^2</p>
<p>tri/circle: r^2 cancels out, so you’re left with 1/(pi)</p>
<p>For U.S. test takers, was the section 6 writing experimental? (I had 3 writing sections)</p>
<p>It contained a question that mentioned the book all quiet on the western front.</p>
<p>Did anyone have a writing section with a passage about presidential elections and politics (the improving paragraphs part)? Does anyone think it was an experimental section? They usually have something relatively easier than that…</p>
<p>Did it have the text about elections and state votes?</p>
<p>thank you… i put 1/pi … any idea on one question that asked which one does not change??? i put median only didnt change… any ideas?</p>
<p>anyone have the version with the back to back writing sections? it was sections 5 and 6…do you guys know which one was experimental because section 6 was so hard…</p>
<p>what’d you guys get for these questions?
green chemistry:
- what was passage about? Traditional and scientific explanation or social and cultural implications?
- for the third paragraph which talked about the specific examples of cuisine was that a social or biological explanation </p>
<p>math -
-the ratio question how do you do that? it was like the ratio of x to y is 4;2 and ratio of y to z is 3;6 what is ratio of x to z…(the variables and numbers are wrong but that’s the general question)
-was the answer to the car driving 40 and 60 mph 48 or 50? i thought because the distance is the same you can just do 40 + 60 / 2 = 50, but apparently not?</p>
<p>writing -
how many no errors did you guys get for section 5 and section 6 ? in the error identification part</p>
<p>@zuhleen</p>
<p>i put traditional and scientific explanation (wasn’t too sure) </p>
<p>7:4
48mph</p>
<p>@zuhleen</p>
<p>Social and cultural implications (not sure though)
Biological explanation</p>
<p>7/4
48</p>
<p>3 no errors (i only had one writing section)</p>
<p>@blueblue, for the w=xy^2 equation, I made up values and said that x=4, y=3, and therefore w=36. w-x would be 36-4 with these values and you would end up with 32. 3+1=4 would be y+1 and 4 is a factor of 32. I tried this with all 5 factors and found the only one that would not go into 32 was y, which was 3</p>
<p>What were your no errors? were they the press sentence, the freedom of speech sentence, and the government sentence</p>
<p>For the story of the little girl’s birthday party, why was the little girl’s fear “casually easing?”</p>
<p>@blueblue, @texasapex
It is y.
w=xy^2
w-x=xy^2-x
w-x=x(y^2-1)
w-x=x(y-1)(y+1)</p>
<p>@zuhleen
The average speed is 48, not just (40+60)/2 because the average speed is total distance/total time.
So you can pick an arbitrary distance, say 120 miles since it’s a lcm of 40 and 60), if the person drives 120 from home to work and 120 from work to home, they have traveled 240 miles in total. Then, find out how much time it takes each way. It takes 3 hours from home to work (120/40) and 2 hours from work to home (120/60). Then, total distance/total time is 240/(2+3)=48</p>
<p>@zuhleen
the numbers were s/a=7/6 and a/t=3/2
a=3t/2
s/(3t/2)=7/6
s/(t)=(7/6)(3/2)=21/12=7/4</p>
<p>Seriously? Another tread discussing questions on the SAT? This is precisely what the Collegeboard warned students during the test, yet I see forums created literally minutes after the test is completed. This refusal to listen to the canons of the Collegeboard is extremely disappointing, as it is a sign that future generations of America will be intransigent and picaresque. Please, please refrain from consorting in any more of these collusions.</p>
