Janet counts 30 crows on the powerlines and 60% more hawks than crows. How many birds does she count total?

First find how many more hawks than crows there are: 60% * 30 crows =

<<60*.01*30=18>>18 crows Then add that number to the number of crows to find the total number of hawks: 18 crows + 30 crows = <<18+30=48>>48 crows Then add the number of crows to the number of hawks to find the total number of birds: 48 crows + 30 crows = <<48+30=78>>78 crows #### 78 Joan has 180 socks. Two thirds of the socks are white, and the rest of the socks are blue. How many blue socks does Joan have? Joan has (180/3)*2 = <<(180/3)*2=120>>120 white socks. The number of blue socks Joan has is 180-120 = <<180-120=60>>60. #### 60 Simon collected treasures on the beach during his summer vacation. He collected a bucket of pearly seashells, a jar full of smooth sea glass, and a bag of ten sand dollars. If the jar holds three times as many pieces of glass as the bag does sand dollars, and the bucket holds five times as many seashells as the jar holds pieces of glass, how many treasures did Simon find on the beach? The jar holds 3 * 10 = <<3*10=30>>30 pieces of glass. The bucket holds 5 * 30 = <<5*30=150>>150 seashells. Simon found 10 + 30 + 150 = <<10+30+150=190>>190 treasures on the beach. #### 190 Bryce is bringing in doughnuts for his class. There are 25 students in his class, 10 kids want chocolate doughnuts and 15 want glazed doughnuts. The chocolate doughnuts cost $2 each and the glazed doughnuts cost $1 each. How much is the total cost for doughnuts? The chocolate doughnuts cost 10 * $2 = $<<10*2=20>>20. The glazed doughnuts cost 15 * $1 = $<<15*1=15>>15. The total cost for the doughnuts is $20 + $15 = $<<20+15=35>>35. #### 35 Sally needs to make a tablecloth that measures 102 inches by 54 inches. She also needs to make 8 napkins that are 6 by 7 inches. How many square inches of material will Sally need to make the tablecloth and the 8 napkins? Tablecloth = 102 * 54 = <<102*54=5508>>5508 square inches Napkins = 8 * (6 * 7) = <<8*(6*7)=336>>336 square inches 5508 + 336 = <<5508+336=5844>>5844 square inches Sally will need 5844 square inches of material to make the tablecloth and 8 napkins. #### 5844 Kat gets a 95% on her first math test and an 80% on her second math test. If she wants an average grade of at least 90% in her math class, what does she need to get on her third final math test? Let x = the percent needed on her third math test (95 + 80 + x)/3 = 90 (95 + 80 + x) = 270 x = 270 - 95 - 80 x = <<95=95>>95 #### 95 Patricia is growing her long very long to donate it to a charity that makes wigs for cancer survivors. Her hair is 14 inches long. She needs to donate 23 inches to make a wig. She wants her hair to be 12 inches long after the donation. How much longer does she have to grow her hair? Her hair needs to be 35 inches long when she cuts it because 23 + 12 = <<23+12=35>>35 She needs to grow it 21 more inches because 35 - 14 = <<35-14=21>>21 #### 21 Jason joined the military when he turned 18. It took him 8 years to raise to the rank of chief. Then 25% longer than that to go from chief to master chief. He then spent 10 years more in the military before retiring. How old was he when he retired? It took 8*.25=<<8*.25=2>>2 years longer to go from chief to master chief than to get chief So it takes him 8+2=<<8+2=10>>10 years to become a master chief That means he took 10+8=<<10+8=18>>18 years to reach master chief from enlisting So he was in the military for 18+10=<<18+10=28>>28 years So he was 28+18=<<28+18=46>>46 when he retired #### 46 Mabel is counting sharks in the ocean. She knows that of the fish that she sees, 25% will be sharks and 75% will be another type of fish. On day one she counts 15 fish. On day 2 she counts three times as many. How many sharks did she count over those two days? She counts 45 fish on day 2 because 3 x 15 = <<3*15=45>>45 She counts 60 fish in total because 15 + 45 = <<15+45=60>>60 She counts 15 sharks because 60 x .25 = <<60*.25=15>>15 #### 15 Doris works at the Widget Factory in the packing department. She puts 3 widgets in each carton, which are 4 inches wide, 4 inches long, and 5 inches tall. She then packs those cartons into a shipping box before sending it to the loading bay. The shipping boxes are 20 inches wide, 20 inches long, and 20 inches high. How many widgets get shipped in each shipping box? Each carton has an area of 4*4*5 = <<4*4*5=80>>80 square inches. Each shipping box has an area of 20*20*20 = <<20*20*20=8000>>8000 square inches The total number of cartons that will fit into each box is 8000/80 = <<8000/80=100>>100 Since there are 3 widgets in each carton, the total number of cartons in each box will be 3*100 = <<3*100=300>>300 #### 300
