The canadian oil sands industry has generated one billion (109) m3 of contaminated fine tailings. these tailings are a mixture of fine solid particles and water. the solids, which have an average specific gravity of 2.67, account for 32% of the weight of the tailings. (a) how much will it cost, in canadian dollars, to remediate all of the tailings. assume that it costs $1.5 us to remediate 1 ft3 (i. e. one cubic foot) of tailings, and that $1.00 can is worth $0.75 us a foot is 30.48 cm. (b) calculate the volume of solid particles (c) calculate the total mass of tailings

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
