[Question]John started weightlifting when he was 16. When he first started he could Clean & Jerk 80 kg and he could Snatch 50 kg. He manages to double his clean and jerk and increase his snatch by 80%. What is his new combined total lifting capacity?
[Answer]His clean and jerk goes to 80 * 2 = 160 kg. His snatch increases by 50 * .8 = 40 kg. So his snatch is now 50 + 40 = 90 kg. So his total is 160 + 90 = 250 kg. The answer is 250.
Q: Five dozens of people are attending your family reunion. Your family was assigned to bring the cans of soda. Each box of soda contains 10 cans and costs $2 per box. It was assumed that each person can consume 2 cans of soda. If you are six in the family and agreed to pay equally for the cost, how much will each of your family members pay?
A: Five dozens of people is equal to 5 x 12 = 60. 60 x 2 = 120 cans of soda are needed. So, this means 120 / 10 = 12 boxes of soda must be purchased. Thus, it will amount to $2 x 12 = $24. Therefore, each family member will pay $24 / 6 = $4. The answer is 4.
Question: Susan is making jewelry with a repeating pattern that has 3 green beads, 5 purple beads, and twice as many red beads as green beads. If the pattern repeats three times per bracelet and 5 times per necklace, how many beads does she need to make 1 bracelets and 10 necklaces?
Answer: First find the number of red beads per repeat: 3 green * 2 red / green = 6 red. Then add the number of beads of each color to find the total number of bead per repeat: 6 beads + 3 beads + 5 beads = 14 beads. Then multiply the number of beads per repeat by the number of repeats per bracelet to find the number of beads per bracelet: 14 beads / repeat * 3 repeats / bracelet = 42 beads / bracelet. Then multiply the number of beads per repeat by the number of repeats per necklace to find the number of beads per necklace: 14 beads / repeat * 5 repeats / necklace = 70 beads / necklace. Then multiply the number of beads per necklace by the number of necklaces to find the total number of beads used in the necklaces: 70 beads / necklace * 10 necklaces = 700 beads. Then add the number of beads used in a bracelet to the number of beads in the necklaces to find the total number of beads used: 700 beads + 42 beads = 742 beads. The answer is 742.
[Question]Cindy was hired to teach 4 math courses which required her to be in the classroom for 48 hours a week altogether. How much did Cindy earn for teaching 1 math course in a month with exactly 4 weeks if her hourly rate per class is $25?
[Answer]In a week, Cindy spends an average of 48 hours / week / 4 courses = 12 hours / week for 1 math course. In a month, 1 math course is 12 hours / week x 4 weeks / month = 48 hours. Therefore, she earns $25 / hour x 48 hours / week = $1200 a month for 1 math course. The answer is 1200.
Q: A volcano erupts and spews ash into the sky. The ash cloud spreads out in a diameter eighteen times as far as the distance it shot up into the sky. If the ashes erupted three hundred feet into the sky, what was the radius of the ash cloud in feet?
A: The ash cloud spread out 300 * 18 = 5400 feet in diameter. The radius is half the diameter, so the ash cloud had a radius of 5400 / 2 = 2700 feet. The answer is 2700.
Question: A mosquito sucks 20 drops of blood every time it feeds on someone. If there are 5000 drops per liter and you have to lose 3 liters of blood to die, how many mosquitoes would have to feed on you to kill you?
Answer:
First find the total number of liters a mosquito sucks in one feeding: 20 drops / 5000 drops / liter = .004 L / feeding. Then divide the lethal amount of blood by the amount of blood one mosquito can drain: 3 L / .004 L / feeding = 750 feedings. The answer is 750.
