Afaucet in a bathtub pours out 2 1/4 gallons of water every minute.
how many gallons of water will pour out in 3 1/2 minutes?
express your answer in simplest terms.

Simply multiply 2 1/4 x 3 1/2  = 7 7/8 gallons of water or 7.875

In 1 minute 2 1/4 gallons
In 2 minutes  4 1/2 gallons  (2 1/4 x 2)
In 3 minutes   6  3/4   (2 1/4 x 3)
In the remaining 1/2 minute it will pour out 1  1/8  gallons   (2 1/4 ÷ 2)
Add that to the 6  3/4 and you will also get 7  7/8 gallons

step-by-step explanation: sorry if not correct becaude my brother is loud and i could not think!

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.
