Question 7 4 points Save Answer Pipes R, S, and T are connected to the same tank. When all three pipes are running, they can fill the tank in 2 hours. When only pipes S and T are running, they can fill the tank in 6 hours. When only R and T are running, they can fill the tank in 2.4 hours. How long would it take each pipe running alone to fill the tank? Hint: If in 1 hour x is the amount of the tank filled by pipe R, y the amount filled by pipe S, and z the amount filled by pipe T, then use the equation below 0 a. It would take pipe R 3 hours, pipe S 12 hours and pipe T 10 hours to fill the tank running alone. b. It would take pipe R 3 hours, pipe S 13 hours, and pipe T10 hours to fill the tank running alone. C. It would take pipe R 3 hours, pipe S 12 hours, and pipe T 11 hours to fill the tank running alone. d. It would take pipe R 3 hours, pipe S 13 hours, and pipe T 12 hours to fill the tank running alone. e.It would take pipe R 3 hours, pipe S 12 hours, and pipe T 12 hours to fill the tank running alone. Question3 4 points S Matrices were used to solve a system of two linear equations. The final matrix is shown here. What does the result tell about the system? 1 3-6 O a. The system has no solution. It is inconsistent. b. The system has infinitely many solutions. The equations are dependent. C. The system has exactly one solution.
