She gave her paper away to eight people because giving her paper pieces to four students ,equals one whole piece of paper, and she has two, so two times 4 equals 8.
Answer:8
Calculate both of those per hour:
2/3 crate / hour
1.25 crates / 2 hours = 5/8 crates / hour
2/3 + 5/8 = 16/24 + 15/24 = 31/24 per hour =
124 / 24 crates in 4 hours = 5 (4/24) crates =
5 (1/6) crates per 4 hours
The supplementary angle of 120° is 60°.
So your answer is 60 degrees.
