Question 8: Jeremy was hanging out with his grandpa the other day and they were talking about the value of money. His grandpa said, "back in my
day, you could buy a cup of coffee for a nickel." Suppose inflation
decreases the value of money by 2% each year. How long until $100 is
worth $50? (Round your answer to the nearest whole number of years)

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
