Answer:
Step-by-step explanation:
<u><em>The value of r is the question is</em></u>
r=0.03
we know that
The formula to calculate continuously compounded interest is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
e is the mathematical constant number
we have
substitute in the formula above
solve for t
Apply ln both sides
![ln(3)=ln[(e)^{0.03t}]](https://tex.z-dn.net/?f=ln%283%29%3Dln%5B%28e%29%5E%7B0.03t%7D%5D)
Apply property of logarithms
![ln(3)=(0.03t)ln[(e)]](https://tex.z-dn.net/?f=ln%283%29%3D%280.03t%29ln%5B%28e%29%5D)

<em>trucks/cars = 2/3 = x/9 = 30/y</em>
<em>x = 2×9/3 = 18/3 = 6</em>

Answer:
18432 km/h
Step-by-step explanation:
It is given that a sound wave travels through iron at a rate of 5120 m/s.
We know that
1 km = 1000 m
1 hour = 60 minutes
1 minutes = 60 second
Using these conversions we get
1 m = 0.001 km
1 hour = 3600 second
Therefore, the sound wave travels through iron at a rate of 18432 km/h.
Hey there! I'm happy to help!
6x=5x+22
Let's move all the variables to the left. We subtract 5x from both sides.
x=22
Have a wonderful day! :D
