protocol for flushing a cooling water system at a nuclear reactor requires that a drain valve be opened while the fill pumps are active. the drain valve can empty the tank to thr cut-off in 10 minutes. the pump can fill the rank from the cut-off in 14 minutes. during the flushing process, how long will it take for the initially full tank to reach the cut-off level while following the protocol?​

Statement reason 1. δabc is similar to δced. given 2. 3. definition of slope 4. slope of slope of definition of slope 5. slope of × slope of multiplying the slopes 6. slope of × slope of substitution property of equality 7. slope of × slope of simplifying the right side the table contains the proof of the relationship between the slopes of two perpendicular lines. what is the reason for statement 2? a. parallel line segments that meet a common perpendicular line are proportional in length. b. the lengths of vertical and horizontal sides in congruent triangles are in a common ratio. c. trigonometric identities determine the lengths of the legs in a right triangle. d. corresponding side lengths in similar triangles are proportional in length.
