Round your answer to two decimal places.
-The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is 8 amperes when the resistance is 727 ohms. What is the current when the resistance is 899
Ohms? Round to the nearest tenth.
A) 0.2 amperes
B) 9.9 amperes
C) 6.5 amperes
D) 0.1 amperes

The relationship between current (I) and resistance (R) is given by $I = \frac{k}{R}$, where $k$ is a constant. When $I = 8$ amperes and $R = 727$ ohms, we can find $k = I \times R = 8 \times 727 = 5824$. To find the current when $R = 899$ ohms, we use $I = \frac{5824}{899}$, which gives $I \approx 6.48$ amperes, rounded to the nearest tenth as 6.5 amperes.
