Answer:

The ramp must cover a horizontal distance of approximately 19.081 feet.

Step-by-step explanation:

Given the vertical distance (y), measured in feet, and the angle of the wheelchair ramp (\theta), measured in sexagesimal degrees. The horizontal distance needed for the ramp (x), measured in feet, is estimated by the following trigonometrical expression:

x = \frac{y}{\tan \theta} (1)

If we know that y = 1\,ft and \theta = 3^{\circ}, then the horizontal distance covered by this ramp is:

x = \frac{1\,ft}{\tan 3^{\circ}}

x \approx 19.081\,ft

The ramp must cover a horizontal distance of approximately 19.081 feet.

What is 5/8 as a percent and a decimal
Makovka662 [10]

To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. If we want to write 5/8 as a percent, we need to find a fraction equivalent to 5/8 that has a 100 in the denominator. We can do this by setting up a proportion.

\frac{5}{8} = \frac{n}{100}

<h3 /><h3>8n = 500</h3><h3>÷8     ÷8</h3><h3>    n = 62.5%</h3><h3>Therefore, 5/8 is equal to 62.5%.</h3><h3 />

To write a fraction as a decimal, we can simply divide the numerator by the denominator.

5 ÷ 8 = 0.625

Therefore, 5/8 is equal to 0.625.
