Answer:
14
Step-by-step explanation:
14-12<3
What you have to do is subtract 3 2/15 from 7 5/9. You can also use decimals but that doesn't work all the time since the are infinite numbers (you will see what I mean later on) So what you can do is find the improper fraction of each one, and subtract it from each other. It would be 68/9 - 47/15, which would give you a total of 4 19/45. YOU'RE WELCOME :)
John's effective annual rate is about
(1 +.0576/4)^4 -1 ≈ 5.8856%
According to the "rule of 72", John's money will have doubled in
72/5.8856 = 12.23 years
John's balance will be $4500 in 1989.
_____
Since you're only concerned with the year (not the month), you don't actually need to determine the effective annual rate. The given rate of 5.76% will tell you 72/5.76 = 12.5 years. The actual doubling time is closer to 12.12 years, so using the effective rate gives results that are closer, but "good enough" is good enough in this case.
Answer:
<h2>D</h2>
Step-by-step explanation:
The dimensions of the portrait are attached.
The total area of the portrait is represented by its width 5+x and its length x+1.
We know by definition that the area of a rectangle is
Where 
is the width and 
is the length.
Using the given expressiones, we have
Therefore, the right answer is D.
