For this case, the first thing we must do is define variables.
x: amount of time Miguel uses to complete the task.
y: amount of time Maria uses to complete the task.
We write the system of equations:
x + y = 60
y = (1/2) x
Solving the system we have:
x = 40 minutes
y = 20 minutes

Answer:
.79 mm^2
Step-by-step explanation:
First find the area of the circle
A = pi r^2
A = 3.14 (1) ^2
A = 3.14
Now we have 1/4 of the circle
The area is 1/4 of the full area
1/4 *3.14
.785
Rounding to the nearest hundredth
.79 mm^2
b = 3
