As per the problem
The escalator make a 30° angle with the floor .
The escalator have a vertical height of 36 feet.
Now draw the diagram with the given information, the diagram is attached below
From the diagram,
Horizontal length=AB=d
Distance traveled by the person on the escalator stairs=AC=l
In triangle ABC,
Again in triangle ABC, Using Pythagoras Theorem
The horizontal length needed is
The distance a person would travel on the escalator stairs is 72 ft
Step-by-step explanation:
A=2πr(r+h)
A=6.28×14mm(+29mm)
A=77.92(14mm+29mm)
A=77.92×43
A=3350.56 mm

<span>Hello : let
A(-10,-3) B(7,14)
the slope is : (YB - YA)/(XB -XA)
(14+3)/17) = 1
an equation is : y=ax+b a is a slope</span>
y = x +b
the line F through point B(7,14) :
14 =7+b<span>
<span>b = 7
the equation is : y =X+7</span></span>
<span>the x- intercept of F when y=0 : x+7 =0 so : x = - 7 </span>
Answer:
21
Step-by-step explanation:
8.75=25
8.75*2=50
17.5+
1.75=5
1.75*2=10
3.5
3.5+17.5=21
