- Q13Maria and her classmates are designing a plan to help manage energy use at their school. They want to choose the best type of light bulbs so the school can save energy and lower costs. Maria finds that this table with data comparing different types of light bulbs. Which is the most logical way for Maria and her classmates to use the data?the price per bulb, the bulbs needed for 50,000 hours use only, and ignore the rest of the datalifespan in hours, energy usage per 50,000 hours, and bulbs needed per 50,000 hours usethe number of bulbs needed for 50,000 hours use, the energy usage per 50,000 hours, and the price per bulbthe price per bulb, the lifespan in hours only, and ignore the rest of the data45s
- Q14What is the most logical way for Matthew and Sarah should develop to conserve energy?Close the curtains on the sunny side of the house only, close the doors to unused rooms, and set the air conditioner to a slightly warmer temperature.Open the curtains on the shady side of the house only, close the doors to unused rooms, and set the air conditioning to the usual temperature.Close the curtains on the shady side of the house only, open the doors to all the rooms, and set the air conditioning to a slightly warmer temperature.Open the curtains on the shady side of the house only, open the doors to all rooms, and set the air conditioning to a slightly cooler temperature.45s
