3 children painted a local park track of 5000m, Alex painted 70m, Dell painted 15m, and Tony painted 35m. This pattern continues to the end of the track. What percentage of the park did each child paint? 70 + 15 + 35 = 120 When we take[URL='https://www.mathcelebrity.com/modulus.php?num=5000mod120&pl=Calculate+Modulus'] 5000 divided by 120[/URL], we get: 41 remainder 80 So we have: [LIST] [*]Alex: 70 * 41 = 2870 [*]Dell: 15 * 41 = 615 [*]Tony: 35 * 41 = 1435 [/LIST] Now Alex goes next, and paints the full 70. So he has: 2870 + 70 = 2940 Dell goes next, and paints the last 10 615 + 10 = 625 Now for percentages: [LIST] [*]Alex: 2940/5000 = [B]58.8%[/B] [*]Dell: 625/5000 = [B]12.5%[/B] [*]Tony: 1435/5000 = [B]28.7%[/B] [/LIST]

9 friends brought 178 tickets How many more ticket would they have to buy for all of them could have
9 friends brought 178 tickets How many more ticket would they have to buy for all of them could have the same amount? If we take [URL='https://www.mathcelebrity.com/modulus.php?num=178mod9&pl=Calculate+Modulus']178 mod 9[/URL] to find the remainder, we get 7. If we buy the 7 more (remainder) tickets, we have: 9 friends - 7 remainder = 2 tickets To prove our work, we add the 2 tickets + 178 tickets = 180 tickets 180 tickets / 9 friends = 20 tickets per friends So our answer is [B]2 tickets[/B]

A company has 12,600 employees. Of these, 1/4 drive alone to work, 1/6 car pool, 1/8 use public transportation, 1/9 cycle, and the remainder use other methods of transportation. How many employees use each method of transportation? Find the remainder fraction: Remainder = 1 - (1/4 + 1/6 + 1/8 + 1/9) The least common multiple of 4, 6, 8, 9 is 72. So we divide 72 by each fraction denominator to get our multiplier: 1/4 = 18/72 1/6 = 12/72 1/8 = 9/72 1/9 = 8/72 Add those all up: (18 + 12 + 9 + 8)/72 47/72 Now subtract the other methods out from 1 to get the remainder of who use other methods: Remainder = 1 - 47/72 Since 1 = 72/72, we have: (72 - 47)/72 [B]25/72[/B]

A farmer is taking her eggs to the market in a cart, but she hits a pothole, which knocks over all
A farmer is taking her eggs to the market in a cart, but she hits a pothole, which knocks over all the containers of eggs. Though she is unhurt, every egg is broken. So she goes to her insurance agent, who asks her how many eggs she had. She says she doesn't know, but she remembers somethings from various ways she tried packing the eggs. When she put the eggs in groups of two, three, four, five, and six there was one egg left over, but when she put them in groups of seven they ended up in complete groups with no eggs left over. What can the farmer figure from this information about the number of eggs she had? Is there more than one answer? We need a number (n) that leaves a remainder of 1 when divided by 2, 3, 4, 5, 6 but no remainder when divided by 7. 217 + 84 = [B]301[/B]. Other solutions are multiples of 3 x 4 x 5 x 7, but we want the lowest one here.

Oscar makes a large purchase at Home Depot and plans to rent one of its trucks to take his supplies home. The most he wants to spend on the truck is \$56.00. If Home Depot charges \$17.00 for the first 75 minutes and \$5.00 for each additional 15 min, for how long can Oscar keep the truck and remain within his budget? Set up the cost equation C(m) where m is the number of minutes for rental: C(m) = 17 * min(m, 75) + max(0, 5(m - 75)) If Oscar uses the first 75 minutes, he spends \$17. So he's left with: \$56 - \$17 = \$38 \$38 / \$5 = 7 Remainder 3 We remove the remainder 3, since it's not a full 15 minute block. So Oscar can rent the truck for: 7 * 15 minute blocks = [B]105 minutes[/B]
