For the values given, a and b are legs of right triangle. find the length of the hypotenuse. if necessary, round to the nearest tenth. 7. a = 6, b = 8 8. a = 5, b = 9 9. a = 4, b = 10 10. a = 9, b = 1 11. a = 7, b = 3.5 12. a = 1.4, b = 2.3

7.) Hypotenuse is 10

8.)Hypotenuse is 10.3

9.) Hypotenuse is 10.8

10.) Hypotenuse is 9.1

11.) Hypotenuse is 7.8

12.) Hypotenuse is 2.7

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
