Sammy has 3 pancakes . he cuts each one in half. how many pancake halves are there ?

6 halves.

Step-by-step explanation:

Sammy has 3 pancakes.

He cuts each pancakes in half.

now each pancake has two halves.

The total number of pancake halves are = 3 × 2

                                                                    = 6 halves

There are 6 halves of 3 pancakes.

probably the last option

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.
