3(0.3x +1.3) = 2(0.4x -0.85)
Verdich [7]

Answer:

Step-by-step explanation:

3(0.3x + 1.3) = 2(0.4x - 0.85)

0.9x + 3.9 = 0.8x - 1.70

0.9x - 0.8x = - 1.70 - 3.9

0.1x = - 5.6

x = - 5.6 / 0.1

x = - 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\°
