I NEED HEL Anita needs to construct ten cones for a class project. How many square feet of material will she need? Use 3.14 for π. Enter your answer in the box.

Step-by-step explanation:

Given : 1/16 ÷ 1/81 + - 1/8To find: multiplicative inverseSolution:a multiplicative inverse is basically a reciprocalMultiplicative inverse of number is the number which if multiplied by original number result in 11/16 ÷ 1/81 + -1/81/16 ÷ 1/81 = 81/16+ - 1/8 = - 1/881/16 - 1/8= 81/16 - 2/16= (81 - 2)/16= 79/16Multiplicative inverse = 16/79

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
