A magician is training for an underwater escape trick. Upon first trying, she could hold her breath for 36 seconds. Now, using a different technique, she can hold it for 75% longer. How long can the magician currently hold her breath

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140

hey there : ) your answer would be a.

step-by-step explanation:

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
