Answer:
A is the answer- Density = number of books over volume of shelf
Step-by-step explanation:
Density is mass/volume, so the number of books is the mass and the volume of the shelf is the volume for this equation.
Answer:
-1.4335
Step-by-step explanation:
Answer:
If width = 60 m, length = 195 m.
If width = 150 m, length = 465 m.
Step-by-step explanation:
The area of a rectangle is l * w or length times width.
So we can set an equation (letting w = width and x = length)
w = 
Part 1: width = 60m:
60 = 
65 = 
x = 195 m
Part 2: width = 150 m:
150 = 
155 = 
x = 465 m
Recall that an equation in slope-intercept form is as follows:

where m is the slope of the line, and (0,b) is the y-intercept.
Substituting m=-6, and b=-1/2 we get:

Simplifying the above result we get:
