Area of semicircle = (πr²) ÷ 2
Area of semicircle:
= (3.14)(2)² ÷ 2
= (3.14)(4) ÷ 2
= 12.56/2
= 6.28
Use the permutation formula
nPr = (n!)/((n-r)!)
20P15 = (20!)/((20-15)!)
20P15 = (20!)/(5!)
The final answer is choice A
The missing value is 6 so 2/5 = 6/15
Use the formula for the area of a circle, which is pi*r^2
r=2, so pi*2^2=12.56
12.56+28 is 40.56 m^2

Answer:
20x+63
Step-by-step explanation:
add all of the multiplying factors which increase at the same rate, in this case it is 7.00 a ticket and 13.00 for food per person, making it 20.00 per person. Then place your variable next to that to signal the solver they are multiplying them, finally adding the 63.00 because they only need one bus and it isn't multiplying by the number of people.
