A large bottle of juice contains 500 milliliters of juice. A medium bottle contains 80% as much juice as the large bottle. How many milliliters of juice are in the medium bottle?

400 milliliters

Step-by-step explanation: To find 80 percent of 500 you first covert the percentage into a decimal. To do this, you move the decimal point two spaces to the left. 80.0% becomes 0.8 as a decimal. Then you multiply it by 500. 500 times 0.8 equals 400.

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
