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
100 cm
1 m is equivalent to 100cm
Answer:
x = 21°
Step-by-step explanation:
Complementary angles have a sum of 90°. If ∠A + ∠B = 90°, we know that
x - 6° + 3x = 90°.
4x - 6° = 90°
4x = 96°
x = 24°
