Problem

A power plant that uses steam to turn turbines produces 40, point, 0, degree, start text, C, end text hot water. The manufacturer must cool this water before releasing it. So, the manufacturer mixes every 1, point, 00, start text, k, g, end text of its hot water with 3, point, 00, start text, k, g, end text of 20, point, 0, degree, start text, C, end text water.
Calculate the final temperature of the water.
Round your answer to the nearest tenth.
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
  • an exact decimal, like 0, point, 75
  • a multiple of pi, like 12, space, start text, p, i, end text or 2, slash, 3, space, start text, p, i, end text
degree, start text, C, end text
