What are all values of $p$ such that for every $q>0$, we have $$\frac{3(pq^2+p^2q+3q^2+3pq)}{p+q}>2p^2q?$$ Express your answer in interval notation in decimal form.
First we'll simplify that complicated expression. We attempt to factor the numerator of the left side: \begin{align*} pq^2+p^2q+3q^2+3pq &= q(pq + p^2 + 3q + 3p) \\ &= q[ p(q+p) + 3(q+p) ] \\ &= q(p+3)(q+p). \end{align*}Substituting this in for the numerator in our inequality gives $$\frac{3q(p+3)(p+q)}{p+q}>2p^2q.$$We...

The sequence of integers in the row of squares and in each of the two columns of squares form three distinct arithmetic sequences. What is the value of $N$?

Since $18 - 14 = 4$, the common difference in the first column of squares is 4, so the number above 14 is $14 - 4 = 10$, and the number above 10 is $10 - 4 = 6$.

Two parabolas are the graphs of the equations $y=2x^2-10x-10$ and $y=x^2-4x+6$. Find all points where they intersect. List the points in order of increasing $x$-coordinate, separated by semicolons.
First, set the two equations equal to each other to get $2x^2-10x-10=x^2-4x+6$. Combine like terms to get $x^2-6x=16$. To complete the square, we need to add $\left(\dfrac{6}{2}\right)^2=9$ to both sides, giving $(x-3)^2=16+9=25$. So we have $x-3=\pm5$. Solving for $x$ gives us $x=-2$ or $8$.

The first four terms in an arithmetic sequence are $x+y$, $x-y$, $xy$, and $x/y$, in that order. What is the fifth term? Express your answer as a common fraction.
Since the difference of the first two terms is $-2y$, the third and fourth terms of the sequence must be $x-3y$ and $x-5y$.

The fact that 60 workers produce 240 widgets and 300 whoosits in two hours implies that 100 workers produce 400 widgets and 500 whoosits in two hours, or 200 widgets and 250 whoosits in one hour. Let $a$ be the time required for a worker to produce a widget, and let $b$ be the time required for a worker to produce a wh...

An o-Pod MP3 player stores and plays entire songs. Celeste has 10 songs stored on her o-Pod. The time length of each song is different. When the songs are ordered by length, the shortest song is only 30 seconds long and each subsequent song is 30 seconds longer than the previous song. Her favorite song is 3 minutes, 30...
We will calculate the probability of her hearing every second of her favorite song and then subtract that from 1 to get the probability that we're looking for. There are a total of $10!$ ways in which the 10 songs can be ordered. If her favorite song is the first song, she obviously hears the whole thing, and then ther...

A mathematical organization is producing a set of commemorative license plates. Each plate contains a sequence of five characters chosen from the four letters in AIME and the four digits in 2007. No character may appear in a sequence more times than it appears among the four letters in AIME or the four digits in 2007. ...
If a sequence contains no more than one 0, there are $7\cdot 6\cdot 5\cdot 4\cdot 3 = 2520$ sequences formed from the characters A, I, M, E, 2, 0, and 7. If a sequence contains two 0's, the 0's can be placed in $\binom{5}{2} = 10$ ways, the remaining characters can be chosen in $\binom{6}{3} = 20$ ways, and those remai...
