The answer is {B} 728x2y3.
Answer:
t = 1.94 seconds
Step-by-step explanation:
we have to solve the following polynomial equation:
-16t² + 60 = 0
16t² = 60
t² = 60/16 = 3.75
t = √3.75 = 1.936491673 seconds
the equation also has another possible answer = -1.936491673 seconds, but since time cannot be negative, we have to dismiss that option
The Area of the lawn is:
20m x 14m = 280m^2
The Area of the Circle is:
pi x 5^2 = 78.54
280 - 78.54 = 201.46m^2
Answer:
55%
Step-by-step explanation:
11/20 = 0.55
0.55 = 55%
