it is recommended that for a height of 20 inches,a wheelchair ramp be 19 feet long.what is the value of x to the nearest tenth>
How do you define x?
Suppose a new regulation that the maximum angle of a ramp for wheelchairs is 8°At least long must the new ramp be?Round to the nearest tenth of a foot
To find the value of x, we need to set up a proportion based on the information given.
First, let's convert the height of 20 inches to feet. There are 12 inches in a foot, so 20 inches is equal to 20/12 = 1.67 feet.
Now, we can set up the proportion:
Height / Length = Height / Length
Substituting the values we have:
1.67 / x = 20 / 19
To solve this proportion for x:
1.67 * 19 = 20 * x
31.73 = 20x
Divide both sides by 20:
x = 31.73 / 20
x = 1.59
Therefore, the value of x to the nearest tenth is approximately 1.6 feet.
