0.47619047619 and just round so it'll be 0.48
6x9 + 3^2pi would be the area so 54+9pi=57.14
Answer: 0.1x - 16 (c)
Explanation: The perimeter is the sum of all three sides of the triangle. Since the three side are 0.5x + 9, 3x, and (-3.4x) - 25, the sum is as follows:
0.5x + 9 + 3x + (-3.4x) - 25 = 0.1x - 16
I will use 'hr' to mean hour and 'hrs' to mean hours.
<u>The airplane flies:</u>
200 miles per hr
400 miles per hr
600 miles per hr
Average speed = Total distance ÷ total time
= (200 + 400 + 600)miles ÷ 3hrs = 400miles/hr
Time = Distance ÷ Average speed
= 2000miles ÷ 400miles/hr = 5hrs
