A swimming pool holds 540,000 liters of water. The pool has two drain pipes. When the pool is completely full, the first pipe alone can empty it in 180 minutes, and the second pipe alone can empty it in 120 minutes. When both are draining together, how long does it take to empty the pool?

What is the approximate value of  x  in the equation below.–3.396–0.7080.3040.955

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i. e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?

Using the rise/run counting method, the slope of the line is
