<span>A dust particle weighs 7.42 × 10-10 kilograms.
Weight of 5 × 106 dust particles = </span>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

Answer:
2400 and 3600
Step-by-step explanation:
Radio 1 cost = x
Radio 2 cost= 6000- x
- x*1.2+(6000-x)*0.9= 6000*1.02
- 1.2x-0.9x+5400=6120
- 0.3x= 6120-5400
- 0.3x= 720
- x=720/0.3
- x= 2400
- 6000- x= 3600
