Answer:
3 1/3π
Step-by-step explanation:
First, you have to find the circumference. The circumference, based on the equation of 2rπ, comes out as 20π. Since you have to find the length of the arc that is 60 degrees, divide 60 by 360 to see how much of the circle 60 degrees is. It results in 1/6, so then you simply have to multiply 20π by 1/6.
3 2/3=11/3
14 2/5=72/5
11/3x72/5=264/5
264/5=52 4/5
Let 't' represent the time of the walk in minutes.
5.1*t = 220
t = 43.14 min
The person needs to walk at least 43.14 minutes to but at least 220 calories.
Coin: 50%; 1/2 chance to get heads
dice: 17%; 1/6 chance to get 2
The second line
least to greatest: -3, -2.4, -21/4, -1.5, -11/8
