u are trying to help a friend calculate their utilization rate for their study time. They can complete a maximum of 60 HW problems per hour. In the last hour, they were a little distracted but managed to complete 20 HW problems. What is their utilization rate (in %)? Calculate as a percentage (thus .05 would be entered as 5)

The average electricity consumption of a house in Gainesville is known to be 924 kWh in a month (One month = 30 days). They would like to install solar panels of 24 % efficiency to generate this electricity. Given that the average solar power density in Gainesville is 5.47 kWh/m2/day, how much surface area must the panels occupy? Calculate the result in m² but do not write the unit. Round off you answer to a whole number (zero decimal place.)

The solar power per unit area at the Earth's distance from the sun--called the "solar constant"--is 1.36 kW/m^2. If a solar power station in a sunny location uses 20%-efficient solar panels, what area of panels is required to replace a 1.0 GW power plant at noon. Express the answer in square kilometers. 3676
Our crossflow scrubber is collecting 90 % of the 3-µ particles entering. The water drops are all of the same diameter, 400 μ (with Vt = 1.5 m/s). We now install new spray nozzles that make all the drops 200 μ (with Vt = 0.7 m/s) in diameter. QL is not change. What is the new collection efficiency?
Compact florescent light bulbs save energy when compared to traditional incandescent bulbs. Our green energy campaign includes efforts to get local residents to change their incandescent bulbs to florescent bulbs. Initially 184 households make the change. Market studies suggest that, in the absence of limiting factors, we could increase that number by 28% each month. In our target area, there are 246,744 households, which we take as the limiting value. Make a logistic model that gives the number of households converting to florescent bulbs after t months. (Use t as your variable. Round r to three decimal places.)
