[Question]A rectangular flowerbed in the city park is 4 meters wide. Its length is 1 meter less than twice its width. The government wants to fence the flowerbed. How many meters of fence are needed?
[Answer]Twice the width is 4 x 2 = 8 meters. The length of the rectangular flowerbed is 8 - 1 = 7 meters. Since the rectangular flower bed has 2 equal lengths, then it needs 7 x 2 = 14 meters of fence. The rectangular bed has also 2 equal widths, so it needs 4 x 2 = 8 meters of fence. Therefore, the rectangular flower bed needs a total of 14 + 8 = 22 meters of fence. The answer is 22.
Q: Mason opens the hood of his car and discovers that squirrels have been using his engine compartment to store nuts. If 2 busy squirrels have been stockpiling 30 nuts/day and one sleepy squirrel has been stockpiling 20 nuts/day, all for 40 days, how many nuts are in Mason's car?
A: First find the number of nuts the two busy squirrels gather per day: 2 squirrels * 30 nuts / day / squirrel = 60 nuts / day. Then add the number the sleepy squirrel gathers each day: 60 nuts / day + 20 nuts / day = 80 nuts / day. Then multiply the number of nuts gathered daily by the number of days to find the total number of nuts gathered: 80 nuts / day * 40 days = 3200 nuts. The answer is 3200.
Question: In 6 months Bella and Bob will be celebrating their 4th anniversary. How many months ago did they celebrate their 2nd anniversary?
Answer: First, we find their current point in time be realizing that 4 years is 4 sets of 12 months, meaning at that anniversary they will have been together 4 * 12 = 48 months. Then, we subtract their 6 month difference, finding they are at 48 - 6 = 42 months into their relationship. Since 2 years would be 2 * 12 = 24 months into the relationship. We take the larger number, 42, and subtract the smaller number, 24 to find the difference in months, meaning it is 42 - 24 = 18 months. The answer is 18.
[Question]The electricity price in Coco's town is $0.10 per kW. Coco's new oven has a consumption rate of 2.4 kWh (kilowatt-hours). How much will Coco pay for using his oven only if he used it for a total of 25 hours last month?
[Answer]If Coco used his oven 25 hours last month and its energy consumption is 2.4 kW per hour, then we consumed a total of 25 * 2.4 = 60 kW on his oven last month. If the price of electricity is $0.10 per kW, then 60 kW would cost = $0.10 * 60 = $6. The answer is 6.
Q: Bob runs 6 miles per hour. His friend Jim runs at 9 miles per hour. If Bob has a 1 mile head-start, how many minutes will it take before Jim catches him?
A: Bob runs .1 miles per minute because 6 / 60 = .1. Jim run at .15 miles per minute 9 / 60 = .15. We know that .1(Number of Minutes) + 1 = .15(Number of Minutes). Therefore 1 = .05(Number of minutes). Therefore (Number of minutes) = 20 because 1 / .05 = 20. The answer is 20.
Question: Jasper will serve charcuterie at his dinner party. He buys 2 pounds of cheddar cheese for $10, a pound of cream cheese that cost half the price of the cheddar cheese, and a pack of cold cuts that cost twice the price of the cheddar cheese. How much does he spend on the ingredients?
Answer:
A pound of cream cheese cost $10 / 2 = $5. A pack of cold cuts cost $10 x 2 = $20. Jasper spent $10 + $5 + $20 = $35 on the ingredients. The answer is 35.
