Bryce, a mouse lover, keeps his four pet mice in a roomy cage, where they spend much of their spare time (when they are not sleeping or eating) joyfully scampering about on the cage's floor. Bryce tracks his mice's health diligently and just now recorded their masses as 14.5 g,14.5 g, 18.3 g,18.3 g, 13.3 g,13.3 g, and 10.5 g.10.5 g. At this very instant, the xx ‑ and yy ‑components of the mice's velocities are, respectively, (0.127 m/s, −0.907 m/s),(0.127 m/s, −0.907 m/s), (−0.781 m/s, −0.103 m/s),(−0.781 m/s, −0.103 m/s), (0.867 m/s, 0.471 m/s),(0.867 m/s, 0.471 m/s), and (−0.213 m/s, 0.851 m/s).(−0.213 m/s, 0.851 m/s). Calculate the xx ‑ and yy ‑components of Bryce's mice's total momentum, pxpx and py.

At Prairie Elementary School, students are asked to pick their lunch ahead of time so the kitchen staff will know what to prepare. On Monday, 6 times as many students chose hamburgers as chose salads. The number of students who chose lasagna was one third the number of students who chose hamburgers. If 225 students ordered lunch, how many students chose each option if hamburger, salad, and lasagna were the only three options?

You pull a sled across a horizontal frictionless patch of snow. If your pulling force is in the same direction as the sled's displacement and increases the kinetic energy of the sled by 27%, by what percentage would the sled's kinetic energy increase if the pulling force acted at an angle of 46° above the horizontal?

A bus driver follows a morning route and an afternoon route each day. Because there are more cities on the morning route, the average speed is 12 miles per hours less than the afternoon route. She covers 70 miles on the morning route in the same amount of time she covers 100 miles on the afternoon route. Find the average speed on the afternoon route

A certain motorcycle manufacturer has been building motorcycles for 98 years. Over that period, production has increased steadily at an annual rate of 5%, so that the production rate, in motorcycles/year, after t years wasr(t)=A⋅1.05^twhere A is a constant representing the initial production rate. What fraction of their total production was built during the last 13 years? Your answer should be a number between 0 and 1.
