Answer: the rate uphill is 6 mph.
The rate downhill is 10 mph
Step-by-step explanation:
Let x represent the rate at which the jogger ran uphill.
The jogger runs 4 miles per hour faster downhill than uphill. This means that speed at which the jogger ran downhill is (x + 4) mph
Time = distance/speed
if the jogger can runs 5 miles downhill, then the time taken to run downhill is
5/(x + 4)
At the same time, the jogger runs 3 miles uphill. It means that the time taken to run uphill is
3/x
Since the time is the same, it means that
5/(x + 4) = 3/x
Cross multiplying, it becomes
5 × x = 3(x + 4)
5x = 3x + 12
5x - 3x = 12
2x = 12
x = 12/2
x = 6
The rate downhill is 6 + 4 = 10 mph
Answer:
Interes ganado= €59.07
Step-by-step explanation:
Dada la siguiente informacion:
300€ durante 5 años al 0.3% de interés compuesto mensual.
<u>Para calcular el valor final de la inversión y el interés ganado, debemos usar la siguiente formula:</u>
FV= PV*(1 + i)^n
Present Value= 300
i= 0.003
n= 5*12= 60 meses
FV= 300*(1.003^60)
FV= 359.07
Interes ganado= 359.07 - 300
Interes ganado= 59.07
Answer:
Step-by-step explanation:
7x + 8y + 5z
I put the equations in parentheses, assuming that I would be adding both of the equations together. Then, I removed them and combined the like terms. I used two calculators to check my answer, and this should be correct.
