Answer:
c
Step-by-step explanation:
When you provide heat (thermal energy) to the gas molecules, their root mean square velocity (kinetic energy) increases, as a result they the gas exerts a higher pressure on the walls of the balloon and the balloon expands.
Multiply, because the total price is ten percent more than the original: $75 x 1.1 = <span>$82.5</span>
x - y = 16
x^2 + x^2 = 130
----------------
x^2 - y^2 = 256
+(x^2 + y^2 = 130)
2x^2 = 386
x^2 = 193
x = <span>13.892 (3DP)
----
</span>x - y = 16
13.892 - y = 16
-y = 2.108
y = -2.108
The numbers are: 13.892 and -2.108
For this case we propose a rule of three:
31700 ------------> 8.8%
x ----------------------> 100%
Where "x" represents the number of copies sold to date.
Thus, to date 360,227 copies of the book have been sold.
ANswer:
To date, 360,227 copies of the book have been sold.
