Halmi had the most appropriate information because when you add both the girls and the boys up it is 56 after that you have to add 14+14=28.
28/56= exactly %50 of the entire group.
X - y = 2400/6 = 400 where x = speed of plane and y = speed of wind.
x + y = 2400/5 = 480 - flying with the wind
adding the 2 equations
2x = 880
x = 440
Speed of the plane with no wind = 440 mph
Answer:
B is true.
Step-by-step explanation:
All rational numbers are integers
That will be any color out of 12 that is the probaility.
area = PI x r^2
radius = 1/2 diameter
1/2 of 8 = 4
3.14 x 4^2 = 3.14 x 16 = 50.24 square inches ( answer may vary depending on what you use for PI. 3.14 is common)
