Itd be $4.78
1200/251.2=4.77707006, rounded to the nearest cent would be $4.78 :)
Arc length = 2 π R (C/360)
where:
C is the central angle of the arc
R is the radius of the arc
arc length = 2 π R (137/360) = 2.39R
By replacing you get:
5*7-2*11+3*(-1) = 35-22-3= 10
so the answer is 10.

Answer:
x>12
Step-by-step explanation:
Based on the information given, it can be noted that the air speed that the plane has will be 71.1 km per hour.
The number of hours used for the return trip will be:
= 2 hours - 24 minutes.
= 1 hour 36 minutes.
= 1.6 hours.
Therefore, the speed of the air plane will be:
= (128 + 128) / (2 + 1.6)
= 256/3.6.
= 71.1 km per hour.
