Multiply or divide as indicated watching significant digits. (a) (6.5 ✕ 1018 m)(5.3 ✕ 10-10 m)

(b) (5.2 ✕ 10-7 m)/(3.2 ✕ 10-12 s)

(c) (8.5 ✕ 10-4 km)(1.3 ✕ 10-3 km)

(d) (6.6 ✕ 105 kg)/(3.3 ✕ 103 m3)

4should be the last one n=4

Here for a good time of free question

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
