A group of volunteers are helping create a community garden. The project should take 200 hours of work. If v represents the number of volunteers and each volunteer works eight hours, which equation could be used to determine how many volunteers are needed to finish the project?

step-by-step explanation:

16 is the absolute value

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

a magnifying glass is a convex lens which produces a magnified image of an object. for a magnified image to be observed the distance between the object and the lens has to be shorter than the focal length of the lens.
