Answer:

  78.5 km

Step-by-step explanation:

Measured at the airport, the angle between the two planes is ...

  180° -60° -50° = 70°

The law of cosines tells us the distance between the planes is ...

  d = √(50² +80² -2·50·80·cos(70°)) ≈ √6163.84 ≈ 78.5 . . . km

The planes are about 78.5 km apart.

x+y=19 and 6.5x+3y=74.5 can be used to determine the number of gifts wrapped and number of giftbags prepared where x represents the wrapped gifts and y represents giftbags.

Step-by-step explanation:

Let,

x be the gift wrapped with wrapping paper.

y be the gifts in gift bag.

Time for wrapping one gift = 6.5 minutes

Time for doing 1 gift bag = 3 minutes

Total gifts = 19

Total time = 74.5 minutes

According to given statement;

x+y=19

6.5x+3y=74.5

x+y=19 and 6.5x+3y=74.5 can be used to determine the number of gifts wrapped and number of giftbags prepared where x represents the wrapped gifts and y represents giftbags.
