The weight, W a horizontal beam can safely support varies jointly as the width, T and the square of the depth, D and inversely as the length, L. If a 10-foot beam with a width of 4 inches and a depth of 6 inches safely supports 540 pounds, how many pounds can a 16-foot beam that has a width of 3.5 inches and a depth of 4 inches be expected to support? Round to the nearest pound. Assume the two beams are made of the same material.

Ascientist has 50 grams of a radioactive element. the amount of radioactive element remaining after t days can be determined using the equation (1) after two days the scientist receives a second shipment of 50 grams of the same element. the equation used to represent the amount of shipment 2 remaining after t days is 10) - 50 which of the following is an equivalent form of the expression for the amount remaining in shipment 2? what’s the answer?
