If you can find your way through all the smoke of the definition,
you find that an increase of 10 times the intensity is an increase
of 10 dB.
Next, if you can find your way over, under, around, and through
all the speeds and distances of the vehicles, you'll find that you
don't need them. Right in the middle of the pile, it says "intensity
10 times that of ...". That right there tells you that the sound of
the truck is 10 dB louder than the sound of the car.
So the car is 70 dB (asked for, and then given), and the truck is 80 dB.

Answer:
7.2 years
Step-by-step explanation:
where f(t) is the length and t is the number of years old
given the Mike measures 148 cm, we need to find out the age
So we plug in 148 for f(t) and solve for t
divide both sides by 200
Now subtract 1 from both sides
Divide both sides by -0.956
Now take ln on both sides
divide both sides by -0.18
t=7.2
So 7.2 years
is the same as 
Dividing by 3 is the same as multiplying by the fraction 1/3
