Assume that when you take a bath, you fill a tub to the halfway point. The tub measures 6 feet by 3 feet by 2.6 feet.
masya89 [10]

Using the volumes, it is found that you spend more water taking a bath.

<h3>What is the volume of a rectangular prism?</h3>

The volume of a rectangular prism of length l, width w and height h is given by:

V = lwh.

For this problem, the dimensions of the tub are as follows:

l = 6, w = 3, h = 2.6.

You use half of that, hence:

V = 0.5 x 6 x 3 x 2.6 = 23.4 feet³.

For the bath, the number of cubic feet is:

1.42 x 11/7.5 = 2.08 feet³.

Hence you spend more water taking a bath, as 23.4 > 2.08.

A plane flies at 350 mph in the direction N 40° E with a wind blowing at 40 mph in the direction S 70° E. What is the plane’s dr
kozerog [31]

Answer:

The drift angle is approximately 7.65° towards the East from the plane's heading

Step-by-step explanation:

The speed of the plane = 350 mph

The direction in which the plane flies N 40° E = 50° counterclockwise from the eastern direction

The speed of the wind = 40 mph

The direction of the wind = S 70° E = 20° clockwise from the eastern direction

The component velocities of the plane are;

R_{Plane} = (350 × cos 50)·i + (350 × sin 50)·j

R_{Wind} = (40 + cos 20)·i - (40 × sin 40)·j

The resultant speed of the plane = R_{Plane} + R_{Wind} = 265.915·i +242.404·j

The direction the plane is heading = tan⁻¹(242.404/265.915) ≈ 42.35°

Therefore, the drift angle = Actual Angle - Direction of the plane = 50 - 42.35 ≈ 7.65° towards the East
