The Tanaka family and the Butler family each used their sprinklers last summer. The water output rate for the Tanaka family’s sprinkler was 20L per hour. The water output rate for the Butler family’s sprinkler was 40L per hour. The families used their sprinklers for a combined total of 45 hours, resulting in a total water output of 1200L. How long was each sprinkler used?

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
