Need you must show all your work and answer the questions in complete sentences! my niece wanted to create a coverup she saw on pinterest. it required a square piece of patterned fabric. we found an online store with some bright and fun samples of fabric at a reasonable price. they charge a flat shipping fee of $10 and then $3 per yard. the formula 3n + 10 = t can be used to determine the total cost of the fabric, where n is the number of yards purchased, and t is the total cost of the fabric. 3n + 10 = t 1. what is the dependent variable (or write “neither” if there is not one)? explain why or why not: 2. since all squares are similar, then the ratio of one square’s side to perimeter is proportional to any other’s. if the side of a square of fabric is 2 yards, then the perimeter is 8 yards. use a proportion to determine the perimeter of a square with a side 9 yards long. write your final answer in a complete sentence.
