answer:First, let's find out how many popsicle sticks Sid and Sam have. If Steve has 12 popsicle sticks and Sid has twice as many as Steve, Sid would have 2 * 12 = 24 popsicle sticks. Since Sam has three times as many popsicle sticks as Sid, Sam would have 3 * 24 = 72 popsicle sticks. Now we can add up all their popsicle sticks: 12 (Steve) + 24 (Sid) + 72 (Sam) = 108 popsicle sticks. They can use 108 popsicle sticks for their Art class activity.,Steve has 12 popsicle sticks. Sid has twice as many as Steve, so Sid has 12 x 2 = 24 popsicle sticks. Sam has three times as many as Sid, so Sam has 24 x 3 = 72 popsicle sticks. To find out how many popsicle sticks they can use for their Art class activity, we add up the number of sticks each person has: 12 + 24 + 72 = 108 popsicle sticks. 108 The answer is: 108, To find out how many popsicle sticks Sam, Sid, and Steve have together, we first need to determine how many sticks Sid and Sam have. We know that Sid has twice as many popsicle sticks as Steve: Sid's sticks = 2 * Steve's sticks = 2 * 12 = 24 Now we know that Sam has three times as many popsicle sticks as Sid: Sam's sticks = 3 * Sid's sticks = 3 * 24 = 72 To find out how many popsicle sticks they have in total, we add the number of sticks each of them has: Total sticks = Steve's sticks + Sid's sticks + Sam's sticks = 12 + 24 + 72 = 108 So, Sam, Sid, and Steve together have 108 popsicle sticks for their Art class activity.

answer:Let's break down the problem step-by-step: We're told that Ella got 4 incorrect answers on a 40-item exam. Since there are 40 questions, it means Ella answered 40 - 4 = 36 questions correctly. Now, we also know that Marion got 6 more than half the score of Ella. To find the half of Ella's score, we'd divide her total score by 2. In this case, Ella's correct answers equal 36 * 4 = 144 points. Half of Ella's score would be 144 / 2 = 72 points. Adding the 6 extra points that Marion got, we find that Marion scored 72 + 6 = 78 points on the exam. So, Marion's score on the 40-item exam is 78., Ella got 4 incorrect answers, so she must have gotten 40 - 4 = 36 correct answers. Since Marion got 6 more than half the number of correct answers that Ella got, Marion got (36 / 2) + 6 = 18 + 6 = 24 correct answers. Therefore, Marion's score is 24 out of 40.,If Ella got 4 incorrect answers, then her score is 40 - 4 = 36. Half of Ella's score is 36 / 2 = 18. Marion got 6 more than half of Ella's score, so Marion's score is 18 + 6 = 24. Therefore, Marion's score is 24. 24 The answer is: 24

answer:Half the number of pages in Selena's book is 400/2 = 200 pages. 20 fewer pages than half the number of pages in Selena's book is 200 - 20 = 180 pages. Therefore, there are 180 pages in Harry's book. 180 The answer is: 180, To find the number of pages in Harry's book, we need to first determine what "20 fewer than half the number of pages in Selena's book" means. Half of the pages in Selena's 400-page book is: Half of Selena's pages = Pages in Selena's book / 2 = 400 / 2 = 200 pages Now, we subtract 20 pages from this value: Pages in Harry's book = Half of Selena's pages - 20 = 200 - 20 = 180 pages So, Harry's book has 180 pages.,To find the number of pages in Harry's book, we first need to find the number of pages Harry needs to read, which is half the number of pages in Selena's book. Half of Selena's book is: 400 pages / 2 = 200 pages Now let's calculate the initial number of pages in Harry's book: 200 pages - 20 pages = 180 pages Therefore, there are 180 pages in Harry's book.

answer:Amanda wants to maintain an average of 93% over the 5 quizzes this semester, so we need to find out the total number of points she needs on all quizzes. Let's call the score on the final quiz x. The average for the previous quizzes is 92%, so the total score for the previous quizzes would be: (4 quizzes) x (92%) = 368 points. Now, in order to get an average of 93% over 5 quizzes, Amanda needs a total of: (5 quizzes) x (93%) = 465 points. Since Amanda already has 368 points from the previous quizzes, the score she needs on the final quiz would be: 465 points (the total necessary) - 368 points (the current score) = 97 points. Therefore, Amanda needs to score an 97/100 (97%) on the final quiz in order to achieve an average of 93% over the 5 quizzes and get an A in the class.,Amanda has taken 4 quizzes and averaged a 92% score on them, so her total score on the 4 quizzes is 4 * 92 = 368. To get an A in the class, Amanda needs to average 93% over the 5 quizzes. So, the total score she needs to achieve on the 5 quizzes is 5 * 93 = 465. Amanda already has a total score of 368, so she needs to score 465 - 368 = 97 on the final quiz. Therefore, Amanda needs to score 97% on the final quiz to get an A in the class. 97 The answer is: 97, First, let's calculate Amanda's current average based on the 4 quizzes she has already taken. Sum of the scores = Number of quizzes * Average percentage = 4 * 92 = 368 Current average = Sum of the scores / Number of quizzes = 368 / 4 = 92% Now, let's assume Amanda achieves a score of X% on the final quiz. After taking the final quiz, there will be a new sum of the scores and a new average percentage: New sum of the scores = Old sum + Final quiz score = 368 + X New number of quizzes = Old number + 1 = 4 + 1 = 5 New average = New sum / New number of quizzes = (368 + X) / 5 We know that the new average needs to be 93% for Amanda to get an A in the class. So, we can set up an equation: 93 = (368 + X) / 5 Now, let's solve for X: 5 * 93 = 368 + X 465 = 368 + X X = 465 - 368 X = 97 Therefore, Amanda needs a score of 97% on the final quiz to achieve an overall average of 93% and get an A in the class.
