It would be C.
For example, say 1 person comes. This would be x=1. Plugging this in gives you,
y=0.5 + 1.3
This shows that C is true since x is always going to be multiplied by 0.5.
1.3 would be the base amount of time it takes to arrange since if it the y-intercept.

To calculate the area it is pi*r^2
so since r = 1/2 d
2.5^2 * pi = area
or
19.625
Answer: m
=
3
Step-by-step explanation:
let the speed of plane in still air be x and that wind be y
therefore:
x+y=490
x-y=390
next we solve for the values of x and y, first we add the above equations. This will give us:
2x=880
x=880/2
x=440 miles per hour.
substituting the value of x in one of the equations and solving for y we get:
440+y=490
y=490-440
y=50 miles per hour
