The decimal equivalent of the fraction2 1/5 is . the number of digits that should be overlined is

2.2, because decimals deal with tenths, hundredths, and thousandths, so 1/5 translates to 2/10, which in decimals is .2, and then you add the 2 to your answer.
Hope this helps!

The answer is 9.7 cm

so the perpendicular line goes through the given pointyou would get a perpendicular line at some random location

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.
