Sophie bought a water fountain for her cat. The fountain holds 57 fluid ounces of water. To fill it Sophie uses a jar that holds 1 pint. How many times must she fill the jar to fill the fountain completely?

4 times

Step-by-step explanation:

if she has a jar that holds 1 pint you do 57/ 1 pint (16 ounces) and you have to fill it up 4 times for the fountain to be empty

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
