Three moons are in the same circular orbit around a planet. the moons are each 120,000 kilometers from the surface of the planet, located at points a, b, and c. the planet is 60,000 kilometers in diameter and m∠abc=90∘. how far is point a from point c?

300,000 km

Step-by-step explanation:

The diameter of the orbit is 60,000 + 2·120,000 km = 300,000 km. The 90° angle at B must subtend an arc of 180° of that circle. That places points A and C on the ends of a diameter, hence 300,000 km apart.

the answe i =−n+5

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
