- In 1906, San Francisco experienced an intense earthquake with a magnitude of 7.8 on the Richter scale. In 1989, the Loma Prieta earthquake also affected the San Francisco area, and measured 6.9 on the Richter scale. Compare the intensities of the two earthquakes.arrow_forwardIn 2014, Chile experienced an intense earthquake with a magnitude of 8.2 on the Richter scale. In 2014, Los Angeles also experienced an earthquake which measured 5.1 on the Richter scale. Compare the intensities of the two earthquakes.arrow_forwardBobby is working in a lab testing bacteria populations. After starting out with a population of 258 bacteria, he observes the change in population and notices that the population doubles every 12 minutes. Step 2 of 2: Find the population after 2 hours. Round to the nearest bacterium.arrow_forward
- A driver of a car stopped at a gas station to fill up his gas tank. He looked at his watch, and the time read exactly 3:40 p.m. At this time, he started pumping gas into the tank. At exactly 3:44, the tank was full and he noticed that he had pumped 10.2 gallons. What is the average rate of flow of the gasoline into the gas tank? Enter the exact answer. The average rate of flow of the gasoline is Number acer K 1 gallons per minute.

- Suppose there is a 1.3∘F drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 49.9∘F, what will be the temperature when the plane reaches an altitude of 7,000 feet?arrow_forwardEvery day the teacher drinks a cup of coffee before her 9:00 class. Suppose the temperature is 200⁰F when you serve it in your mug at 8:30. 15 minutes later the coffee cools to 130⁰F in a room that is 71⁰F, however the teacher will not drink the coffee until it cools to 94⁰F. How many minutes after serving will she drink the coffee?arrow_forwardAt 3:30pm, a thermometer reading of 75 degrees F is taken outside where the air temperature is 22 degrees F. At 3:33pm, the thermometer reading is 40 degrees F. Later, the thermometer is brought inside where the air temperature decreases to 73 degrees F. At 3:42pm, the reading of the thermometer is 70 degrees F. At what particular time was the thermometer brought indoors?arrow_forward
- Athena is raising the Colorado state flag on the school’s flagpole. This is her first time raisingthe flag, so she is excited and raises the flag faster and faster. Athena soon feels tired andpauses for a short break. Finally she finishes raising the flag to the top and a slower steadyrate.At the end of the day, Athena lowers the flag. At first she lowers it slowly at a constantrate, and then lowers the flag faster and faster until the flag comes all the way down.Choose ONE of the graphs below that provides a graphical representation of the relationshipbetween time and the total distance traveled by the flag. Explain how your choice representseach part of the scenario.arrow_forwardFrom 2025 to 2030 there is a net change of 1067 students. (t=0 corresponding to the current year, 2020)arrow_forward
