When grizzly bears hibernate, their heart rates go down to 10 beats per minute, which is 20% of normal value. What is a grizzly bear's usual heart rate when not hibernating?
20 % = 20 / 100 = 0.2
heart rate when not hibernating:
10 / 0.2 = 50 beats per minute
TY FOR THE HELP
100-80%=20%
20/100= 0.2
0.2/10 =50 heart beats
To find the grizzly bear's usual heart rate when not hibernating, we need to first calculate the normal heart rate.
Given that during hibernation, the heart rate decreases to 10 beats per minute, which is 20% of its normal value, we can set up an equation:
10 = 0.2 * x
Here, 'x' represents the grizzly bear's normal heart rate.
To solve for 'x', we can divide both sides of the equation by 0.2:
10 / 0.2 = x
This simplifies to:
50 = x
Therefore, a grizzly bear's usual heart rate when not hibernating is 50 beats per minute.
