[Answer]Each part of the wire is 50 / 5 = 10 meters long. Ernest used 3 parts, then he used 10 x 3 = 30 meters of the wire. Therefore, 50 - 30 = 20 meters of wire is not used. The answer is 20.
Q: It takes a dog groomer 10 minutes to dry a short-haired dog like a beagle. It takes him twice as long to dry a full-haired, fluffy dog like a german shepherd. One morning, he has 6 short-haired dogs to dry and 9 full-haired dogs to dry. How many hours does it take him to dry all of the dogs?
A: It takes 10 minutes to dry the coat of a short - haired dog and twice as long for a full haired dog so they take 10 * 2 = 20 minutes to dry. He had 6 short hair dogs and they took 10 minutes to dry each so they took 6 * 10 = 60 minutes to dry. He had 9 full haired dogs that took 20 minutes to dry each so they took 9 * 20 = 180 minutes to dry. Together is takes him 60 + 180 = 240 minutes to dry all of the dogs. 60 minutes are in 1 hour and he spends 240 minutes on the dogs so he worked for 240 / 60 = 4 hours drying the dogs. The answer is 4.
Question: Brittany has 3 gerbils: Puffy, Muffy, and Scruffy. Puffy weighs 5 ounces more than Muffy. Muffy weighs 3 ounces less than Scruffy. If Scruffy weighs 12 ounces, how much would the scale indicate, in ounces, if Brittany put Puffy and Muffy on the scale?
Answer: Muffy weighs 12 - 3 = 9 ounces. Puffy weighs 5 + 9 = 14 ounces. If Brittany weighs both Puffy and Muffy, the scale would read 9 + 14 = 23 ounces. The answer is 23.
[Question]In a week, Rayman works out for half the number of hours Junior takes to work out. Wolverine, their friend, works out for twice the combined total number of hours both Rayman and Junior take during their workouts. Calculate the number of hours Wolverine takes doing her workouts if Rayman does workouts for 10 hours in a week.
[Answer]If Rayman takes 10 hours doing his workouts, half the number of hours junior takes, then Junior takes 2 * 10 = 20 hours to do his workouts in a week. Altogether, Junior and Rayman take 20 + 10 = 30 hours doing their workouts in a week. Wolverine takes 2 * 30 = 60 hours to do her workouts in a week, twice the total number of hours Rayman and Junior takes. The answer is 60.
Q: Tom originally was only able to lift 80 kg farmer handles per hand. After some training, he was able to double this number. He then decided to specialize and was able to get an extra 10%. How much weight can he hold in total?
A: After doubling he was able to hold 80 * 2 = 160 kg per hand. Specialization gave him another 160 * .1 = 16 kg. So he lifted 160 + 16 = 176 kg per hand. That means he lifted a total of 352 kg. The answer is 352.
Question: There were 180 apples in each crate. 12 such crates of apples were delivered to a factory. 160 apples were rotten and had to be thrown away. The remaining apples were packed into boxes of 20 apples each. How many boxes of apples were there?
Answer:
The total number of apples delivered was: 180 apples x 12 crates = 2160 apples. So, the number of remaining apples after throwing away the rotten ones was: 2160 apples 160 apples = 2000 apples. And now, we can find the total number of boxes of apples by dividing the remaining number of apples by the number of apples per box: 2000 apples / 20 apples / box = 100 boxes of apples. The answer is 100.
