Answer:
Step-by-step explanation:
1) 6*10³
2) 4*10²
3) 8*10⁴
4)9000 = 9*10³
5) 400,000 = 4 *10⁵
6)4000 = 4*10³
7) 450 = 4.5 * 10²
8) 55 000 = 5.5*10⁴
9) 350 = 3.5*10²
10) 750 000 = 7.5*10⁵
1. 600 / 900 = 260/x
234,000 / 600 = 390
the length = 390 feet
2. 100/20 = d/60
100/20 = 5
d = 60x5 = 300 feet
