When a grizzly bear hibernates, its heart rate drops to 10 beats per minute, which is 20%, percent of its normal value. What is a grizzly bear's normal heart rate when not hibernating?
To find the answer, you set up an equation:
You put the 20% into decimal form by sliding the decimal place two spaces to the left. The "x" represents the grizzly bear's normal heart rate.
10 = .20x
Now, you divide both sides by .20
You should get:
50 = x
A grizzly bear's normal heart rate when it is not hibernating is 50 beats per minute.
Answer:
50
Step-by-step explanation:
20% is 1/5 of 100. So you multiply 10 by 5 and you get 50.
