Answer:

His normal heart rate is 50 beats per minute.

Step-by-step explanation:

Since when it is hibernating it beats 10 times per minute and that is 20 % of the normal volume we can use a rule of 3 to find his normal herat rate. If 10 times per minutes is 20% of its normal volume then x times per minutes is 100%. So we have:

10 -> 20%

x -> 100%

10/x = 20/100

20x = 1000

x = 50 beats per minute

Answer:

50 beats per minute

Step-by-step explanation:

To find the heart hate of a grizzly bear when not hibernating, we need to get the heart rate when hibernating (10 beats per minute) and make it equal to 20% in a rule of three, where we want to know the 100% value (normal heart beat rate):

10 beats per minute -> 20%

X beats per minute -> 100%

10/X = 20/100

X = 100 * 10/20 = 50
