Answer:

The wind speed is 20 miles per hour.

Step-by-step explanation:

Speed = distance/time.

With the wind

230 + w = 400 / t   where w is the speed of the wind.

Against the wind:

230 - w = 336/t

From the above equations:

t = 400/ (230 + w)

t = 336/ (230 - w)  So:

400/ (230 + w) = 336/ (230 - w)

336(230 + w) =  400(230 - w)

77280 + 336w = 92000 - 400w

736w =  92000 - 77280 = 14720

w =  14720 / 736

w = 20.

Phil had 2 quarters, 1 dime and 3 pennies = 63 cents
Paul had 2 nickles = 10 cents

Total 63 + 10 = 73 cents

If Paul had 1 cent more than Phil, then Paul would have 37 cents and Phil would have 36 cents
but Paul had 10 cents 
10 cents + 27 cents = 37 cents

so 
1 quarter and 2 pennies Phil gave to Paul, total 27 cents

Answer

Phi gave Paul 1 quarter and 2 pennies.

Answer:

Hypotenuse MN = 10.54 ft (Approx.)

Step-by-step explanation:

Given:

Base OM = 9.6 ft

Angle θ = 13'

Find:

Hypotenuse MN

Computation:

Using trigonometry function

Cos θ = Base / Hypotenuse

Cos 13 = 9.6 / Hypotenuse

0.97 = 9.6 / Hypotenuse

Hypotenuse MN = 10.54 ft (Approx.)
