Fertilizer is sold in 100 pound bags labelled with the amount of nitrogen (n), phosphoric acid ( p205), and potash (k20) present. the mixture of these nutrients varies from one type of fertilizer to the next. for example, a 100 pound bag of vigoro ultra turf fertilizer contains 29 pounds of nitrogen, 3 pounds of phosphoric acid, and 4 pounds of potash. another type of fertilizer, parkerâdos premium starter, has 18 pounds of nitrogen, 25 pounds of phosphoric acid, and 6 pounds of potash per 100 pounds. determine the amount of each type required to yield a mixture containing the 112 pounds of nitrogen, 81 pounds of phosphoric acid, and 26 pounds of potash. the mixture contains pounds of vigoro, and ! pounds of parkerâ d s. hint: let x1 be the amount of 100 pound bags of vigoro, and x, the amount of 100 pound bags of parker. set up and solve the system in the unknowns x1 and x2 and then multiply the solution by 100 to find the number of pounds.

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.

:i need some real : a store sells shirts to the public at one pricing scale and wholesale at another pricing scale. the tables below describe the cost, y, of x shirts. (after tables) how do the slopes of the lines created by each table compare? the slope of the public table is 3/4 of the slope of the wholesale table. the slope of the wholesale table is 3/4 of the slope of the public table. the slope of the public table is 12 times greater than the slope of the wholesale table. the slope of the wholesale table is 12 times greater than the slope of the public table.
