In this case, the ladder formed a triangle with the wall, you can see it in the attached diagram.
Let the distance of ladder from base of wall = x
Now to find the value of x, we use cosine ratio.
cos ∅= Adjacent / Hypotenuse
Put values
cos72= x/15
15 cos 72 = x
or
x=15 cos 72
x=4.6 ft ( Rounded to nearest tenth)
So, the distance of ladder from base of the wall is 4.6 ft.
Answer:
Option D.
Step-by-step explanation:
An inverse variation function is defined as
where, k is constant of proportionality.
In the above equation x represents input and y represents output.
If the function's input value is multiplied by 4, then
The output is divided by 4.
Therefore, the correct option is D.
40% * 150 =
= 40/100 * 150 =
= 4/10 * 150 =
= 2/5 * 150 =
= 2/1 * 30 =
= 2 * 30 =
= 60
