1.Farmer brown wants to spend exactly 376 dollars on cows,pigs, and sheep and he wants to buy exactly 40 of these animals. If cows are 14 dollars each , pigs are 6 dollars each and sheep are 3 dollars each . How many of each should he buy (buying at least one of each species)
2.Depth(m) 1.5, 3, 4.5, 6, 7.5, 9 N60 5,7, 9, 8, 12, 11This table gives the variation of the field standard penetration number, N60 in a sand deposit. The groundwater table is located at a depth of 5.5m. The dry unit weight of sand from 0 to a depth of 5.5m is 18.08 kN/m^3, and the saturated unit weight of sand for depths of 5.5 tp 10.5m is 19.34 Kn/M^3. Use the relationship of Liao and Whitman to calculate the corrected penetration numbers.
