On a farm, there are 2 cows, 3 pigs, and 6 goats. The farmer planned on adding 3 cows, 5 pigs, and 2 goats. How many animals will there be on the farm?

Currently, the farm has 2 + 3 + 6 =

<<2+3+6=11>>11 animals. The farmer will add 3 + 5 + 2 = <<3+5+2=10>>10 animals. So, the farm will have 11 + 10 = <<11+10=21>>21 animals. #### 21 Ross takes 17 breaths per minute by inhaling 5/9 liter of air to his lungs. What is the volume of air inhaled in 24 hours? We have 60 minutes per hour. So, in 24 hours we have 60 * 24 = <<60*24=1440>>1440 minutes. So, the volume of air Ross inhaled in 24 hours is: 17 breaths/minute * 5/9 L/breath * 1440 minutes = 122400 / 9 = <<17*5/9*1440=13600>>13600 liters. The volume of air inhaled is 13600 liters. #### 13600 Caprice is taking piano lessons. Her mother pays the teacher $10 for every half-hour of teaching her daughter. If Caprice is taking one lesson per week, and the lesson lasts 1 hour, how much money would the teacher earn in 5 weeks? If half-hour lesson is worth $10, then a one-hour lesson costs 2 * 10 = $<<10*2=20>>20. One lesson per week would mean that in 5 weeks the teacher would earn 20 * 5 = $<<20*5=100>>100. #### 100 Quinton is looking to add 4 fruit trees to his backyard. He wants to plant 2 apple trees that will be 10 feet wide each and need 12 feet between them. The peach trees will be closer to the house and will grow to be 12 feet wide and will need 15 feet between each tree. All told, how much space will these trees take up in his yard? Both apple trees will be 10 feet wide at maturity so they will be 2*10 = <<10*2=20>>20 feet wide Quinton will need to leave 12 feet between these 2 trees so the apple trees will take up 20+12 = 32 feet Both peach trees will be 12 feet wide at maturity so they will be 2*12 = <<12*2=24>>24 feet wide Quinton will need to leave 15 feet between these 2 trees so the peach trees will take up 24+15 = 39 feet Together, the apple trees will take up 32 feet and the peach trees will take up 39 feet so they will take 32+39 = <<32+39=71>>71 feet #### 71 Two puppies, two kittens, and three parakeets were for sale at the pet shop. The puppies were three times more expensive than the parakeets, and the parakeets were half as expensive as the kittens. If the cost of one parakeet was $10, what would it cost to purchase all of the pets for sale at the pet shop, in dollars? Puppies cost three times more than parakeets, or 3*$10=$<<3*10=30>>30 per puppy. Parakeets were half as expensive as the kittens, or 2*$10=$<<2*10=20>>20 per kitten. Two puppies cost 2*$30=$<<2*30=60>>60 Two kittens cost 2*$20=$<<2*20=40>>40. And three parakeets cost 3*$10=$<<3*10=30>>30. Thus, the cost to purchase all of the pets for sale at the pet shop is $60+$40+$30=$<<60+40+30=130>>130. #### 130 Marcus, Humphrey, and Darrel are bird watching. Marcus sees 7 birds, Humphrey sees 11 birds, and Darrel sees 9 birds. How many birds does each of them see on average? They see 27 total birds because 9 +11 + 7 = <<9+11+7=27>>27 They see an average of 9 birds each because 27 / 3 = <<27/3=9>>9 #### 9 In five years Sam will be 3 times as old as Drew. If Drew is currently 12 years old, how old is Sam? In five years Drew will be 12+5=<<12+5=17>>17 years old. In five years Sam will be 3(17)=51 years old. Sam is currently 51-5=<<51-5=46>>46 years old. #### 46 There are 322 voters in District 1. District 2 has 19 less voters than District 3. District 3 has twice as many voters as District 1. How many total voters are in Districts 1 - 3? D1 = <<322=322>>322 D3 = 2 * 322 = <<2*322=644>>644 D2 = 644 - 19 = <<644-19=625>>625 322 + 625 + 644 = <<322+625+644=1591>>1591 There are 1591 voters in Districts 1 - 3. #### 1591 In the Oprah Winfrey High School marching band, each trumpet and clarinet player carries 5 pounds of weight, each trombone player carries 10 pounds of weight, each tuba player carries 20 pounds of weight, and each drum player carries 15 pounds of weight. If there are 6 trumpets, 9 clarinets, 8 trombones, 3 tubas, and 2 drummers, how much weight does the total marching band carry? First find the total number of clarinet and trumpet players: 6 players + 9 players = <<6+9=15>>15 players Then find the total weight of the trumpets and clarinets: 15 players * 5 pounds/player = <<15*5=75>>75 pounds Then find the total weight of the trombones: 8 players * 10 pounds/player = <<8*10=80>>80 pounds Then find the total weight of the tubas: 3 players * 20 pounds/player = <<3*20=60>>60 pounds Then find the total weight of the drummers: 2 drummers * 15 pounds/player = <<2*15=30>>30 pounds Then add the weight of each type of instrument to find the total weight: 75 pounds + 80 pounds + 60 pounds + 30 pounds = <<75+80+60+30=245>>245 pounds #### 245 Ellen is baking bread. It takes 3 hours to rise 1 ball of dough, and then another 2 hours to bake it. If she makes 4 balls of dough one after another and then bakes them one after another when they're done rising, how many hours will it take? Ellen takes 4*3=<<4*3=12>>12 hours in total to rise all balls of dough. It will take 4*2=<<4*2=8>>8 more hours to bake each one. It will take her 12+8=<<12+8=20>>20 hours to make all of the bread. #### 20
