Each member of a four-member relay team ran 100 meters during the relay. The time, in seconds, for each member is shown below. 13.9 s, 12.85 s, 14.82 s, 12.74 s

Which expression finds the total time for the relay team?
100 times 4
(13.9 + 12.85 + 14.82 + 12.74)x4
13.9 + 12.85 + 14.82 + 12.74
13.9 + 12.85 + 14.82 + 12.74 + 100

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
