The article referenced an internet site about the records for distance and time aloft (time in the air) for paper airplanes. The record for distance, 226 feet 10 inches, was set in California in 2012. The record for time in the air, 29.2 seconds, was set in 2010 in Japan.The magazine article also gave the requirements for hosting a contest that would have two events. The first event is a competition to find which paper airplane flies the longest distance, and the second event is a competition to find which paper airplane stays in the air the longest amount of time. Jenna asked her teacher if her class could host a paper airplane contest with the two events, and the teacher agreed. Rosa and Alex helped Jenna make posters announcing the contest.?Rosa found a book with patterns for paper airplanes using a standard?8.5-by-11-inch sheet of paper. The three friends tried several different patterns. One of the patterns Alex chose is shown in this figure.?Jenna, Alex, and Rosa practiced with their paper airplanes and recorded the time and distance for each paper airplane. Each person chose one paper airplane that flew further than the others to compete in the distance competition. This table shows the best distances for the paper airplanes they chose for distance.Each friend also chose a plane that stayed in the air longer than the others for the time aloft competition. This table shows the best times for the paper airplanes they chose for time aloft.The day of the contest finally arrived, and 12 students had entered the contest. The distance competition was first, and Rosa’s plane won when her paper airplane flew 50% farther than the mean of the three best distances in the table of practice distances. The winner of the time aloft competition was Alex's paper airplane, which stayed in the air 3 seconds longer than the mean of the three best times in the table of practice times.The students all agreed that the paper airplane contest was a big success. Alex has some ideas for new patterns for paper airplanes that will fly farther, and Rosa wants a paper airplane that will stay in the air longer for the contest next year.?1.Read "Paper Airplane Contest" and answer the question.More than 20 sheets of paper were used in the paper airplane contest.Which inequality describes the maximum number of competitors, x, who used only one sheet of paper?/files/assess_files/648c388b-0584-4bab-9168-d4fc81968093/formula_sheets/FL-IBTP_Math_Reference_Sheet_Grade_9-12.pdfFL-IBTP_Math_Reference_Sheet_Grade_9-12.pdf?A.?B.?C.?D.??Read the following and answer the questions below:Going to a Baseball Game Going to a Baseball Game Chris is a big fan of the baseball team in the city where she lives, and she loves to go to the games with her family. Chris and her dad are planning a trip to a game for four people. He asked her to determine how much it will cost for their tickets and snacks at the game. Chris’s dad thinks they may go to several games this year.They chose the section of the park where they wanted to sit, and Chris found the prices for seats in that section. She found three ways to buy the tickets.Individual game tickets for the section they chose are $30 per ticket.The cost of a 21-game package of tickets for one seat in their section is $20 per game.A package of 10 tickets costs $200, and they can be used in any combination of single tickets per game or multiple tickets per game in their section.Chris thinks they will each want a hot dog and a soft drink, and two people can share a bag of peanuts. This table shows the cost of those items at the game.FOOD COSTSFood ItemCostHot dog$6.00Soft drink$4.50Peanuts$5.00An additional cost will be the $20 charge at the parking lot.2.Read "Going to a Baseball Game" and answer the question.Chris's dad decided they will purchase individual game tickets this season.
