Dorothy played the first 17 minutes of the hockey game. evelyn then replaced her for the rest of the half. evelyn started the second half ans was replaced by dorothy woth 21 minutes left in the game if each half is 45 minutes long how long did evelyn play during the second half

24 minutes

Step-by-step explanation:

If each half is 45 minutes long, and Evelyn played until there were only 21 minutes left in the second half, she played for 24 minutes in the second half.

21 minutes + 24 minutes = 45 minutes

24minutes

Step-by-step explanation:

If the second half is 45 min. then subtract 21 from 45 to get her time.

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
