The world's largest flower, the giant rafflesia, is 91 cm in diameter. use a calculator to determine the circumference to the nearest tenth. how do you work this out? ?

Well 90 is in the tenths place and one is less than 5; 5 signifying rounding up, so it stays the same at 90. So 90 is your answer

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
