Let
x = minutes used for jogging
y = minutes used for handball
z = minutes used for cycling
Th total time spent is 1 hour (60 minutes), therefore
x + y + z = 60
Because Mike jogs as long as he cycles, therefore
x = z
Therefore
2x + y = 60
or
y = 60 - 2x (1)
Jogging consumes 10 calories/min, handball consumes 9 calories/min and cycling consumes 12 calories/min.
The calories consumed in 60 minutes is 580, therefore
10 x + 9y + 12z = 580
Because x = z,
22x + 9y = 580 (2)
Substitute (1) into (2).
22x + 9(60 - 2x) = 580
22x + 540 - 18x = 580
4x = 40
x = 10
y = 60 - 2x = 40
z = x = 10
Answer:
10 minutes of jogging
40 minutes of handball
10 minutes of cycling.
Answer:
The annual rate of return of the invesment will be -14,97%
Explanation:
The initial investment is 45.000 and after 5 years the value of the investment is only 20.000. Here we can see a destruction of value (20.000 < 45.000). In finance, the time takes an essential part in calculation, so through the interest rate we calculated how bad was the investment in annual terms. The formula is as follows: Final investment value=(Initial investment*(1+interest rate)^(total years)) in our case would be: 20.000=(45.000*(1+interest rate)^(5)) From this formula we got -14,97%
