Jeanette uses 2 1/2 more balls of yarn to knit a blanket than she uses to knit a sweater. Knitting a sweater requires three times as much yarn as knitting a hat. Jeanette uses 1 1/2 balls of yarn to knit a scarf, which is 1/2 ball more than shes uses for a hat

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

Ascientist places 24 cells in a petri dish. she knows the cells grow at an exponential rate, doubling in number every hour. how long will it take (in hours) for there to be 1100 cells in the dish? time to 1100 cells: 5.51832530 hours how long will it take to reach 110 cells? time to 110 cells : 2.1963972 hours what is the average rate of change in the number of cells between 9 hours and 11 hours? average rate of change: cells per hour what is the instantaneous rate of change after 7 hours? instantaneous rate of change: cells per hour note: you can earn partial credit on this problem.
