Answer:
50 beats per minute
Step-by-step explanation:
20/100×h=10
h=10*5
= 50 beats
Area of the shaded region = area of sector ACE - area of Sector ABD
Area of sector ACE = 45/360 * 3.14(7)^2 = 19.2325 square units
Area of sector ABD = 45/360 * 3.14(5)^2 = 9.8125
Area of the shaded region = area of sector ACE - area of Sector ABD = 19.2325 - 9.8125 = 9.42 square units.
I believe the answer is C ....... A is a close second place :(
40% as a fraction in simplest form would be 2/5.
