Answer:

Step-by-step explanation:
First find the slope using the slope using the given points. Remember that the slope is the change in y over the change in x.

So now we have the equation
, and we need to find out what b is. We can do this by pointing a point (either one, but I'll use -1,2) into the equation

Rearrange the equation so it equals b

Put it together and that's the final equation!

One application of volume is determining the density of an object. Assume the object is made of a pure element (eg: gold). If we know the volume (v) of the object, and we know the mass (m), then we can use the formula D = m/v to figure out the density D. Knowing the volume is also handy to determine if the object can fit into a larger space or not. Another application is figuring out how much water is needed to fill up the inner space of the 3D solid (assuming it's hollow on the inside).
The surface area is handy to figure out how much material is needed to cover the outer surface. This material can be paint, paper, metal sheets, or whatever you can think of really. A good example is wrapping a present and the assumption is that there is no overlap.
Answer:
per teacher = 20 students
per tutor = 12 students
72 students = 18 tutors
Step-by-step explanation:
Divide 60 by 3 to get 20
Divide 48 by 4 to get 12
Divide 72 by 4 to get 18
