Answer:

The speed of the wind is 48.56

Step-by-step explanation:

We can use the following formula to calculate the distance:

distance = speed x time

Let w represent the speed of the wind.

If the plane flies with the wind, the speed will be the speed of the plane + the speed of wind. Since it can fly 910 miles, and the speed of the plane is 305

910 = (305 + w) x time (1)

If the plane flies against the wind, the speed will be the speed of the plane - the speed of wind. Since it can fly 660 miles, and the speed of the plane is 305

660 = (305 - w) x time (2)

Since the time is equal for both equation in 1 and 2:

\frac{910}{305+w} = \frac{660}{305-w}

→ 910(305-w) = 660(305+w)

→ 277550 - 910 w = 201300 + 660w

→ 1570w = 76250

→ w = 48.56

A ramp 17 1/2 feet in length rises to a loading platform that is 3 1/2 feet off the ground. Find the angle that the ramp makes w
faltersainse [42]

Answer:

The angle that the ramp makes with the ground is 11.54°

Step-by-step explanation:

From the image attached, we can see that the length of 17 1/2 ft corresponds to the hypotenuse in a right triangle, the length of 3 1/2 ft corresponds to the opposite side.

We can use the fact that the sin(θ) = \frac{Opposite}{Hypotenuse} to find the angle that the ramp makes with the ground.

sin(\theta)=\frac{3.5}{17.5}

The angle is equal to

\theta = sin^{-1}(\frac{3.5}{17.5} )\\\theta = 11.54\°
