Cities $A$ and $B$ are $45$ miles apart. Alicia lives in $A$ and Beth lives in $B.$ Alicia bikes towards $B$ at $18$ miles per hour. Leaving at the same time, Beth bikes toward $A$ at $12$ miles per hour. How many miles from City $A$ will they be when they meet?
The weight of $\tfrac13$ of a large pizza together with $3\tfrac12$ cups of orange slices is the same as the weight of $\tfrac34$ of a large pizza together with $\tfrac12$ cup of orange slices. A cup of orange slices weighs $\tfrac14$ of a pound. What is the weight, in pounds, of a large pizza?
Janet rolls a standard $6$-sided die $4$ times and keeps a running total of the numbers she rolls. What is the probability that at some point, her running total will equal $3?$
Points $A$ and $B$ lie on the graph of $y=\log_2 x.$ The midpoint of $\overline{AB}$ is $(6,2).$ What is the positive difference between the $x$-coordinates of $A$ and $B?$
A digital display shows the current date as an $8$-digit integer consisting of a $4$-digit year, followed by a $2$-digit month, followed by a $2$-digit date within the month. For example, Arbor Day this year is displayed as $20230428.$ For how many dates in $2023$ will each digit appear an even number of times in the $8$-digit display for that date?
Maureen is keeping track of the mean of her quiz scores this semester. If Maureen scores an $11$ on the next quiz, her mean will increase by $1.$ If she scores an $11$ on each of the next three quizzes, her mean will increase by $2.$ What is the mean of her quiz scores currently?
A square of area $2$ is inscribed in a square of area $3,$ creating four congruent triangles, as shown below. What is the ratio of the shorter leg to the longer leg in the shaded right triangle?
In a table tennis tournament every participant played every other participant exactly once. Although there were twice as many right-handed players as left-handed players, the number of games won by left-handed players was $40\%$ more than the number of games won by right-handed players. (There were no ties and no ambidextrous players.) What is the total number of games played?
Usain is walking for exercise by zigzagging across a $100$-meter by $30$-meter rectangular field, beginning at point $A$ and ending on the segment $\overline{BC}.$ He wants to increase the distance walked by zigzagging as shown in the figure below ($APQRS$). What angle $\theta=\angle PAB$ $=\angle QPC$ $=\angle RQB=\cdots$ will produce a length that is $120$ meters? (Do not assume the zigzag path has exactly four segments as shown; there could be more or fewer.)
Consider the set of complex numbers $z$ satisfying $|1+z+z^2|=4.$ The maximum value of the imaginary part of $z$ can be written in the form $\dfrac{\sqrt{m}}{n},$ where $m$ and $n$ are relatively prime positive integers. What is $m+n?$
Flora the frog starts at $0$ on the number line and makes a sequence of jumps to the right. In any one jump, independent of previous jumps, Flora leaps a positive integer distance $m$ with probability $\dfrac{1}{2^m}.$ What is the probability that Flora will eventually land at $10?$
Circle $C_1$ and $C_2$ each have radius $1,$ and the distance between their centers is $\tfrac12.$ Circle $C_3$ is the largest circle internally tangent to both $C_1$ and $C_2.$ Circle $C_4$ is internally tangent to both $C_1$ and $C_2$ and externally tangent to $C_3.$ What is the radius of $C_4?$
What is the product of all the solutions to the equation $$
\begin{gathered} \log_{7x}2023\cdot\log_{289x}2023\\ {}=\log_{2023x}2023? \end{gathered}
$$
Each row after the first row is formed by placing a $1$ at each end of the row, and each interior entry is $1$ greater than the sum of the two numbers diagonally above it in the previous row. What is the units digit of the sum of the $2023$ numbers in the $2023$rd row?
