In a game of tug-of-war, a team wins by pulling the flag over its goal line (must be pulled 10 feet). The flag begins at 0. During a game, the flag moves 8 feet to the right, 12 feet to the left, and 13 feet back to the right. Did a team win? Explain. If not,
what does each team need to do in order to win?
Did a team win?
No. The flag did not cross a goal line.
Explanation:
The total movement is 9 feet to the right, which means the team pulling to the right is closer to winning, but the flag has not reached the goal line yet.
What each team needs to do:
The right-side team must pull the flag farther to the right until it crosses their goal line.
The left-side team must pull the flag 9 feet back to the left to return it to 0, and then continue pulling it 10 feet toward their goal line to win.
Eleven Fahrenheit temperatures are shown on a map during a weather report. When the temperatures are ordered from least to greatest, the middle temperature is below 0°F. Do you know exactly how many of the temperatures are represented by negative numbers? Explain.
You do not know exactly how many temperatures are negative. You only know that at least 6 of them are negative, but there could be more.
