so the ice rink diameter is 80 feet what mean that the radius of ice rink is 40 feet
the walkway is 10 feet wide
so 10+40=50 what mean that the radius and the walkway wide make 50 feet length together
using this length area = pi*r^2 = 3,14*(50)^2 = 7850 feet squared
area of ice rink = 3,14*40^2 = 5024 feet squared
area of the walkway = 7850-5024 = 2826 feet squared

b, c, or d is correct because e > 4.8
explanation:
9+10e>57
you have to first leave 10e alone, so you take the opposite sign of the term that is on the same side as the variable and coefficient
57-9=48
so, the inequality will simplify to 10e>48
now all you have to do is isolate the variable e!
for that, simply divide 10 on both sides, one side will cancel out, the other side will come up with the quotient of 4.8
in conclusion, e>4.8
The opposite of each customer's balance is obtained by changing its sign.
They are given below:
Girardi 85.23
Lewis - 20.44
Stien : 116.33
Yuan : - 13.50
Wenner : 9.85
Answer:
okay, so you put 14/20 as a fraction, and find out the percent. that is 70%. then you find 70% of 100, which is 70.
