A 12kg bag of fertilizer covers a rectangular area of 5.5 m by 10.5 m. The store that sells fertilizer ran out of its 12kg bags, and only has 3 kg bags
left. Each 3kg bag costs $8.25, but the store offers 25% off the 3kg
because they ran out of 12kg bags, what would it cost to fertilize a lawn
that measures 9.5 m by 17.2 m? *Round answers to 2 decimal places.

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

Apinhole camera is made out of a light-tight box with a piece of film attached to one side and pinhole on the opposite side. the optimum diameter d(in millimeters) of the pinhole can be modeled by d=1.9[ (5.5 x 10^-4) l) ] ^1/2, where l is the length of the camera box (in millimeters). what is the optimum diameter for a pinhole camera if the camera box has a length of 10 centimeters
