When a grizzly bear hibernates, it's heart rate drops to 10 beats per minute, which is 20% of its normal value. What is a grizzly bears normal heart rate when not hibernating?

Answers

Answer 1

Answer:

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 2

Answer:

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

Variable y varies directly with variable x, and y = 6 when x = 9. What is the value of x when y = 18?

Answers

Well, 18 is 6 x 3

Since y was multiplied by 3, we can multiply x by 3 to get its value

9 x 3 = 27

(9)(6)=(x)(18)
54=18x
3=x

Answers

The graph of the function
f(x) = 4^x - 2
has a constant value from negative infinity to negative 3 and then increases exponentially to positive infinity

Therefore, the answer from the choices is:

Answers

All angles must total 180°

1) x = 180° - 45° - 56° 4) a = 180° - 63° - 90°
x = 79° a = 27°

2) z = 180° - 44° - 90° 5) a = 180° - 135°
z = 46° a = 45°

3) x = 180° - 47° - 45° 6) x = 180° - 52° - 90°
x = 88° x = 38°
y = 180° - 133°
y = 47°
