Solar cells convert sunlight directly into electricity
if solar cells were 200% efficient they would generate about 1000watts of power per square meter of surface area when exposed to direct sunlight
with lower efficiency they generate less power suppose a 1 square meter panel of solar cells has an efficiency of 30 % and receives the equivalent of 2 hours of direct sunlight
how much energy in joules can the solar panel produce each day ? give the value in millions of joules per day

Due to a packaging error, 4 cans labeled diet soda were accidentally filled with regular soda and placed in a 12 pack carton of diet soda. two cans were randomly selected from this 12 pack. what is the probability that both cans were regular soda?

Which number line correctly shows 0.8 + 0.3?

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
