For this case, the first thing we must do is define variables.
We have then:
x: length of the bookshelf
y: thickness of each book
The equation for the number of books is:
Substituting values we have:
Doing the calculation we have:
Answer:
200 copies of this book will fit on the bookshelf
Answer:
radius r = 2.38732415 m
diameter d = 4.77464829 m
circumference C = 15 m
area A = 17.9049311 m2
Hello there! :)
Answer:
y = -4x.
Step-by-step explanation:
Begin by finding the slope of the line using the slope formula:

Plug in two points on the graph. We can use the points (-1, 4) and (0, 0):

Simplify:
m = -4.
Therefore, the equation of this line in slope-intercept form (y = mx + b) is:
y = -4x.
Answer: Not safe
Step-by-step explanation:
Let the angle of elevation of the ramp be θ, then:

But the maximum angle for the ramp cannot exceed 7.1°. The calculated angle of elevation will make it difficult, if not impossible, for motorized wheelchairs to get up the ramp.
Therefore, the ramp at the local library is not safe for motorized wheelchairs
