The officers of a high school senior class are planning to rent buses and vans for a class trip. Each bus can transport 81 students, requires 8 chaperones, and costs $1,300 to rent. Each van can transport 9 students, requires 1 chaperone, and costs $90 to rent. Since there are 972 students in the senior class that may be eligible to go on the trip, the officers must plan to accommodate at least 972 students. Since only 104 parents have volunteered to serve as chaperones, the officers must plan to use at most 104 chaperones. How many vehicles of each type should the officers rent in order to minimize the transportation costs? What are the minimal transportation costs? The officers should rent buses and vans to minimize the transportation costs.

11. Billy is running away from a Wells Fargo bank at a speed of 13 kilometers per hour (units are km/h). If the distance between the bank and the border to Mexico is 1.9 km, will he be able to get there before the cops arrive in 9 minutes? How long will it take for him to reach the border? (Hint: speed = distance / time, 1 hour = 60 minutes)
A student calibrated a 10-mL graduated cylinder using water. The empty graduated cylinder weighed 24.378 grams. When it was filled with 9.89 mL of deionized water, it weighed 33.826 grams. The temperature of the water was 21.8oC. What is the density of water, based on these measurements?

13. Heat of Condensation A young inventor approaches you with their invention: they propose a solar-powered water-bottle, which condenses the humidity in the air as drinking water. The bottle has a total volume of 2 L and features a rectangular solar panel (10 cm x 20 cm). Can you cover your daily water-requirements (2 L) with this bottle? Calculate the time required for the water bottle to fill completely given the following parameters: (Assume the device operates at 100% efficiency.) Density of Water P 999.65 kg m-3 Molar mass water M 18.015 g mol-1 Enthalpy of evaporation of water AvapH 44.63 kJ mol-1 Average PV-panel power PAPV 150 W m² Daily sunlight hours tDSL 12 hd-1
In 1999, scientists discovered a new class of black holes with masses 100 to 10,000 times the mass of our sun, but occupying less space than our moon. Suppose that one of these black holes has a mass of 1×10^3 suns and a radius equal to one-half the radius of our moon. What is its density in grams per cubic centimeter? The mass of the sun is 2.0×10^30 kg and the radius of the moon is 2.16×10^3 mi (Volume of a sphere =4/3πr^3)
