Identify the opposite of each integer: a. 4 b. −2 c. +125 d. 1,348 e. −27 f. −398

a. −4

b. 2

c. −125

d. −1,348

e.  27

f. 398

The correct answer is C) 0.03.

1 square yard is a square whose sides are all 1 yard in length.  1 yard = 3 feet, so each side of this square is 3 ft; this gives us 1 yd² = 3(3) = 9 ft².  This gives us 15/9 = 1.67 yd²/min.

1 minute = 60 seconds; this gives us 1.67*60 = 0.027 ≈ 0.03 yd²/sec
