Question: In a triangle with angles A, B, and C, A is 60 degrees, and B is two times as big as C. Calculate the angle of B.
Answer: Since the angles in a triangle adds up to 180, and A is 40 degrees, B and C have a total of 180 - 60 = 120 degrees. Since B is two times bigger than C, the total of the angles of B and C is equal to 2C + C = 120. 3C = 120. The angle of C is C = 120 / 3. C is 40. Since B is two times as big as C, B is 2 * 40 = 80 degrees. The answer is 80.
[Question]Marla has to spend 20 minutes driving one way to her son's school, then 70 minutes attending parent-teacher night, then the same amount of time driving home. How many minutes does Marla spend on this errand in total?
[Answer]First multiply Marla's one - way driving time by 2 to find her total driving time: 20 minutes * 2 = 40 minutes. Then add Marla's driving time to the time spent attending the conference to find the total time: 70 minutes + 40 minutes = 110 minutes. The answer is 110.
Q: Lisa, Jack, and Tommy earned $60 from washing cars all week. However, half of the $60 was earned by Lisa. Tommy earned half of what Lisa earned. How much more money did Lisa earn than Tommy?
A: Lisa earned $60 * 1 / 2 = $30. Tommy earned $30 * 1 / 2 = $15. Lisa earned $30 - $15 = $15 more than Tommy. The answer is 15.
Question: Wally buys bears at the park. A bear is priced at $4.00 for the first bear and a discount of 50 cents per bear is given after that. How much does Wally pay for 101 bears?
Answer: If the price of an additional bear drops by fifty after the first purchase, the price of each additional bear is $4.00 - $0.50 = $3.50. Since Wally bought 101 bears, he was charged fifty cents less on 101 - 1 = 100 bears. The total cost for the 100 bears is 100 * $3.50 = $350. For the 101 bears, Wally paid a total of $350 + $4 = $354. The answer is 354.
[Question]Alyssa and Abigail need to collect 100 empty cans for their Science project. As of today, Alyssa collected 30 while Abigail collected 43 empty cans. How many more empty cans should they collect?
[Answer]Alyssa and Abigail collected a total of 30 + 43 = 73 empty cans as of today. So, they still need to collect 100 - 73 = 27 more empty cans. The answer is 27.
[Question]Carl caused a car accident that resulted in $40,000 worth of property damage and $70,000 worth of medical bills. If Carl's insurance company will pay 80% of the costs, leaving Carl to pay the remaining 20%, how much does Carl personally owe?
[Answer]
First find the total cost of the accident: $40,000 + $70,000 = $110,000. Then multiply the total cost by the percentage Carl has to pay to find his personal cost: $110,000 * .2 = $22,000. The answer is 22000.
