Perimeter of a triangle: Side=5 Length=12 (Picture below)

30

Step-by-step explanation:

Use pythagorean Theorem to find the hypotenuse

a² + b² = c²

5² + 12² = c²

25 + 144 = c²

169 = c²

Take the square root of both sides

c = 13

Perimeter = 5 + 12 + 13

p = 30

Two possible answers are:

2/20 gallons per minute and 3/30 gallons per minute.

Explanation:

To find equivalent ratios, we are finding equivalent fractions.  To do this, we would multiply the numerator and denominator of the original fraction, 1/10, by the same constant.

(1*2)/(10*2) = 2/20 and (1*3)/(10*3) = 3/30.
