The local cell phone tower service for your provider has the best service when you are 15 miles from the tower, if the school is 12 miles east and 11 miles south then will you receive the most bars?

No, since the total distance to the cell tower is 16.28 miles, which is farther away than the distance needed to get the best possible service. You are 1.28 miles too far.

Step-by-step explanation:

you have a triangle with sides 12 miles and 11 miles long, so all you need to do is calculate the hypotenuse:

h² = 12² + 11²

h² = 144 + 121

h² = 265

h = √265

h = 16.28 miles
