Two planes that are traveling toward each other are 720 miles apart. One plane is traveling 40 miles per hour faster than the ot
natali 33 [55]

Answer:

y = 460 miles per hr

x = 500 miles per hr

Step-by-step explanation:

Let the planes be X any

Let their speeds be xmiles/hr and ymiles/hr respectively

x = y + 40 (assuming X is faster by 40miles/hr)

Distance travelled by X to meet Y = 0.75x

Distance travelled by Y to meet X = 0.75y

0.75x + 0.75y = 720 --------1

Put x = y + 40 in eqn 1

0.75(y+40) + 0.75y = 720

0.75y + 30 + 0.75y= 720

1.5y = 690

y = 460 miles per hr

x = 460 +40

= 500 miles per hr

Trapezoids and kites hw
miskamm [114]

Answer:

m<C = 101°

m<E = 46°

Step-by-step explanation:

*This was the only problem I could figure out so I'm sorry*

C equals 101° b/c 1/2 a circle angle equals 180° which is the line. Angle F and Angle C are corresponding interior angles (same side angles) so if both of them together should equal 180. 180 - 79 (<F) = 101 (<C).

You do the same thing to find Angle E b/c it's corresponding interior angles to Angle D.

I hope you understand this explanation
