Step-by-step explanation:
Answer:
x = .58
Step-by-step explanation:
5.7 + 4.8x = 8.5
4.8x = 8.5 - 5.7
4.8x = 2.8
x = 2.8 / 4.8 = .58
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
