Blue sky international airport handles passenger to cargo traffic in a ratio of 8 to 5. if 45 cargo planes landed yesterday, how many passenger flights came in?

72 passenger planes

Step-by-step explanation:

ratio passenger to cargo = 8 to 5 = 8/5

Let p = number of passenger planes.

The ratio of passenger to cargo planes that actually landed is p/45.

The ratio in general is 8/5, so 8/5 must equal p/45.

p/45 = 8/5

5p = 45 * 8

p = 9 * 8

p = 72

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
