# Adust particle weighs 7.42 × 10-10 kilograms. what is the weight of 5 × 106 dust particles represented in scientific notation? A dust particle weighs 7.42 × 10-10 kilograms.

Weight of 5 × 106 dust particles = 5 × 10^6 x 7.42 x 10^(-10)

= 5 x 7.42 x 10^(6-10)

= 37.1 x 10^(-4)

= 3.71 x 10^(-3) kilograms = 3.71 x 10^(-3) kilograms

Step-by-step explanation: 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  ion
