December SAT: Math

<p>Can someone tell me wat the answer was for the problem in which they were 3 different intergers A, B, and C and we were asked which expression was not true?</p>

<p>someone start a cumulative for math as well.</p>

<p>if i put 11/3 instead of 10/3... im going to kill myself. ok so some math questions consolidated so far + ones id like to know</p>

<p>millions of oil barrels range: 15</p>

<p>x=.3_ : either 2,5, or 3? i havnt seen anyone provide any concrete evidence on this yet</p>

<p>xyz=80, max x value: 1600</p>

<p>parabola + ray question, p = : 4 (its what i got.. not 100% sure)</p>

<p>y = x+1 on the graph of y=4x-9, what is x: 10/3</p>

<p>gallons of liquid transfered from one to another, fraction 1.5 -> .8 : 7/30</p>

<p>circle radius question: answer was I, II and III</p>

<p>absolute value question, |x|-|y|=10: None of the above</p>

<p>telephone callers, 1200 1:2:3:4 ratio etc : 480</p>

<p>nickles, quarters, dimes: 5</p>

<p>ok just some i wanted to know - some are easy im just giving what i remember. confirm :D?</p>

<p>p and q are in a ratio of 1:5, what is the ratio of n to k. i got 1:4</p>

<p>x+x+x=x... x has to = 0 right?</p>

<p>27=B^3... b=3</p>

<p>rectangle has sides length and width of 2, height 8. what is sum of all sides: 40</p>

<p>the chances of an odd number being picked out of a list of integers is 1/3, what is chance of picking an even number: 2/3 (really easy or a trick question?)</p>

<p>3 segments on a triangle all = 10, and the middle triangle is equiliateral, what is the length of BC: 10 sqr 3</p>

<p>biggets rate of change in temperature diagram: 4pm - 6pm</p>

<p>5/12 voted for 2 people, 1/3 voted for another, and 72 voted for the last candidate, how many voted total: 864</p>

<p>For the voted question I got 228 as my answer. If 1/3 voted for one person, and 5/12 voted for the other two, then 1/4 of the people voted for the last person. 1/4x=72, x=228?</p>

<p>Umm, that's not what I got for the votes one.</p>

<p>I got 288.</p>

<p>(5/12)+(1/3) = 3/4</p>

<p>Therefore, 72 is 1/4 of the votes,
72*4 = 288.</p>

<p>The one about picking an odd number/ratios one was a trick question. I can't remember the question exactly or I would give you my best explanation, but I remember confidently gridding 1/2.</p>

<p>^^288...not 228 was the answer</p>

<p>i got 288 as the total...</p>

<p>Can someone pleasssssee answer my previous post about the a,b,c problem . Im anxious to know whether or not I got a -2 or -3.</p>

<p>The last one....864?</p>

<p>NM</p>

<p>whew.</p>

<p>omg stryke i got somthing like that.........</p>

<p>How about area of the square, 18?</p>

<p>and how was the even/odd question a trick?</p>

<p>every number is either even or odd so if the probability of pulling out an odd is 1/3, it has to be 2/3 for picking out an even.</p>

<p>How was the odd number even number one 1/2?</p>

<p>Probability of picking an odd number, 1/3.
What is the probability of picking even number? why wouldn't it be 2/3?</p>

<p>was the x+y= 3 -6???????? i put -3</p>

<p>Square was 18, yes.</p>

<p>yeah 18 for the square</p>

<p>For the question:</p>

<p>If a circle has a center at (0,0) and point (a,b) is on the circle, which of the following could be the radius of the circle?
I. a
II. b
III. radical(a^2 + b^2)</p>

<p>A. I only
B. III only
C. I and II
D. I and III
E. I, II, and III</p>

<p>Are you sure its E??</p>

<p>By the way, for the 5/12 and 1/3 vote question, the sum of these percentages is .75, which means .25 is 72, and 4 times 72 is 288.</p>

<p>Also, can anyone retell all the given info for the ray/parabola question??</p>

<p>Im fairly sure it was 2/3. A number is either even or odd, and 0 wasnt included</p>

<p>Square was 18, yes.</p>

<p>Keane can you post more about the problem, I slightly remember what you're talking about but I don't remember details.</p>
