Answer:
3.6, 3.60
Step-by-step explanation:
Equivalent decimal numbers may have different numbers of trailing zeros.
_____
<em>Comments on equivalents</em>
The number can be written in several different forms, including ...
and variations on these.
As a straight standard-form decimal number this representation (3.600) indicates it has 4 significant figures. <em>There is no other equivalent standard-form decimal number that will convey the same information regarding significant figures</em>. The form in scientific notation above will convey that information because it retains the two trailing zeros.
The mixed numbers can be considered to have a precision matching that of the fraction, but when we're concerned about the precision of the answer, we usually use a decimal or scientific notation presentation.

a)6 years
b)12 years
c)18 years
we know that
The compound interest formula 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
n is the number of times interest is compounded per year
Part a) 6 years
we have
substitute in the formula above
Part b) 12 years
we have
substitute in the formula above
Part c) 18 years
we have
substitute in the formula above
It takes 2.8 hours for Max to cover the same route by walking with 3 mph. The certain route has 8.4 miles distance which can be acquired by multiplying the velocity and the amount of time (3.5 x 2.4). Then the new amount of time can be acquired by dividing the certain route distance by the new velocity (8.4 / 3). All of the calculations above are calculated with the basic formula of constant velocity which is velocity = change of position/change of time.
