If each of the 5 x 10^5 people living in fresno were on thier cell phones for an average of 60 minutes per day, about how many minutes of cell phone use is this each day? Express your answer in scientific notation.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post

2+1=3 that’s your answer

How many is in each case if there is 12 in each case it would be 40
