question：As a Ukrainian publicist and writer documenting the events of the Russo-Ukrainian War, you decide to publish a series of 5 books, each containing 120 pages. Each page can contain 3 photographs and 2 detailed paragraphs. If you plan to dedicate 40% of each book to photographs and the remaining 60% to text, how many photographs and paragraphs will you be able to include in each book?
answer：First, I need to determine the total number of pages in each book, which is 120 pages.Next, I'll calculate how many pages are dedicated to photographs and how many to text. Since 40% of the book is for photographs, that's 0.4 multiplied by 120, which equals 48 pages. The remaining 60% will be for text, so that's 0.6 multiplied by 120, totaling 72 pages.Each photograph page can hold 3 photographs. Therefore, the total number of photographs in the book is 48 pages multiplied by 3 photographs per page, resulting in 144 photographs.Each text page contains 2 detailed paragraphs. So, the total number of paragraphs in the book is 72 pages multiplied by 2 paragraphs per page, which equals 144 paragraphs.In conclusion, each book will include 144 photographs and 144 paragraphs.
question：There are 6 girls and 8 boys in the school play. If both parents of each kid attend the premiere, how many parents will be in the auditorium?
answer：First, I need to determine the total number of children in the school play. There are 6 girls and 8 boys, which adds up to 14 children in total.Each child has two parents attending the premiere. Therefore, I multiply the total number of children by 2 to find the total number of parents.14 children multiplied by 2 parents per child equals 28 parents.So, there will be 28 parents in the auditorium.
question：Emily is preparing for a large bridge tournament and needs to organize her card decks. A standard deck contains 52 cards. She has 5 full decks and 2 decks that are three-quarters full. However, upon inspection, she notices that many cards are worn out and decides to discard 41 cards. How many cards does Emily have left for the tournament?
answer：First, calculate the total number of full decks Emily has. She has 5 full decks and 2 decks that are three-quarters full.Next, determine the number of cards in the full decks. Each full deck has 52 cards, so 5 full decks contain 5 multiplied by 52, which equals 260 cards.Then, calculate the number of cards in the three-quarters full decks. Each three-quarters full deck has 0.75 multiplied by 52, which equals 39 cards. For 2 such decks, this amounts to 78 cards.Add the cards from the full decks and the three-quarters full decks to find the total number of cards before discarding: 260 plus 78 equals 338 cards.Finally, subtract the 41 worn-out cards that Emily discards from the total. This leaves Emily with 338 minus 41, which equals 297 cards remaining for the tournament.
question：Alex works as a professional who assesses the financial impact of data breaches for companies. One day, Alex is reviewing a case where a company experienced a data breach affecting 500 customer records. The company estimates the cost per breached record is 200 for notifying customers, 150 for credit monitoring services, and 100 for legal fees. Additionally, the company has an insurance policy that covers 60% of these costs. How much will the company pay out of pocket after insurance coverage for the data breach?
answer：First, I need to determine the total cost per breached record by adding up the costs for notifying customers, credit monitoring services, and legal fees.Next, I'll calculate the total cost for all 500 breached records by multiplying the total cost per record by the number of records.After that, I'll apply the insurance coverage of 60% to the total cost to find out how much the insurance will cover.Finally, I'll subtract the insurance coverage amount from the total cost to find out how much the company will pay out of pocket after the insurance coverage.
question：Emma grew up on a quiet farm with wide-open spaces. One day, she decided to visit the bustling city nearby to buy supplies for her family. Feeling overwhelmed by the crowds, she planned her trip carefully. She needed to visit 3 different stores: a bookstore for 5 books, a grocery store for 8 items, and a small shop for 3 tools. Each book costs 6, each grocery item is 4, and each tool is 10. How much money does Emma spend in total during her trip to the city?
answer：First, I need to determine the total cost of each category of items Emma is purchasing.For the books, Emma is buying 5 books at 6 each. So, the total cost for books is 5 multiplied by 6, which equals 30.Next, for the grocery items, she needs 8 items at 4 each. The total cost for groceries is 8 multiplied by 4, amounting to 32.Then, for the tools, Emma is purchasing 3 tools at 10 each. The total cost for tools is 3 multiplied by 10, totaling 30.Finally, to find the overall total amount Emma spends, I will add up the costs of books, groceries, and tools: 30 plus 32 plus 30 equals 92.
question：A technology provider specializing in automation and digitalization solutions for mining operations has developed a new automated drone system to survey a mining site. Each drone can survey an area of 5 square kilometers in one hour. The mining site covers a total area of 120 square kilometers. If the company has 8 drones available, how many hours will it take for all the drones to survey the entire mining site?
answer：First, I need to determine the total surveying capacity of all 8 drones. Each drone can survey 5 square kilometers per hour, so 8 drones can survey 40 square kilometers in one hour.Next, I'll calculate how many hours are required to survey the entire 120 square kilometer mining site. By dividing the total area by the hourly capacity (120 ÷ 40), I find that it will take 3 hours for all the drones to complete the survey.
