A contractor must build a wheelchair ramp with a recommended 8 degree angle of elevation above the horizontal to reach a door on a wall, as shown above. If the elevation from the sidewalk to the bottom of the door is 3.8 feet, how many feet from the wall must the ramp begin? (Round your answer to the nearest tenth of a foot.)

Step-by-step explanation:

Find the diagram attached.

From the diagram:

opposite = AB = 3.8feet

adjacent = BC = x feet

To get the unknown:

tan(theta) = opposite/adjacent

tan(theta) = AB/BC

tan8° = 3.8/BC

BC = 3.8/tan8°

BC = 3.8/0.1405

BC = 27.05 feet

Hence distance of the wall from the ramp is 27.1 feet to the nearest tenth of a foot

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
