Q. When a grizzly bear hibernates, its heart rate drops to 10 beats per minute, which is 20% of its normal value.What is a grizzly bear's normal heart rate when not hibernating?beats per minute
Identify Given Information: Identify the given information and what is being asked.The grizzly bear's heart rate during hibernation is 10 beats per minute, which is 20% of its normal heart rate.We need to find the normal heart rate.
Understand Relationship: Understand the relationship between the hibernating heart rate and the normal heart rate.20% of the normal heart rate is equal to the hibernating heart rate of 10 beats per minute.Let n be the normal heart rate.Then, 0.20×n=10.
Solve for Normal Rate: Solve for n, the normal heart rate.0.20×n=10Divide both sides of the equation by 0.20 to isolate n.n=0.2010
Calculate Normal Rate: Calculate the normal heart rate. n=0.2010n=50The normal heart rate of the grizzly bear when not hibernating is 50 beats per minute.
