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.
Consider a 75-ft wide overflow spillway with no piers and a design head of 18 ft. The crest elevation of the spillway is 2400 ft and the streambed elevation just upstream of the spillway is 2350 ft.
Find the area of the parallelogram with vertices: P(0,0,0), Q(-2,4,0), R(-2,2,-2), S(-4,6,-2).
Two remediation options are being considered for a contaminated land area formerly used for industrial operations. Option 1 involves removing all of the contaminated soil over a two-year period at a cost of $2.2 million per year
The system is initially divided in two parts, with 1/3 of the mass at T1 and 2/3 of the mass at T2. The divider is removed and the system eventually attains equilibrium.
A certain fluid at 15 psia is contained in a cylinder behind a frictionless piston. The initial volume of the fluid is 300 in^3. The fluid expands to a volume of 450 in^3 while the pressure increases to 25 psia.
For a same soil, two moist densities and their corresponding degrees of saturation are given in the following table Density (kg/m^3) S(%) 1700 55 1800 70 What is the void ratio (e) and the specific gravity (Gs)?
Locate the image using both the spherical mirror equation and a ray diagram and identify if it is real or virtual, upright or inverted, and smaller or larger.
Why is the anchorage capacity of a standard hook not increased by extending the bar well beyond the end of the hook?
The central angle is 35 degrees, the superelevation is 0.08, and 20.6 ft is cleared (for sight distance) from the inside edge of the innermost lane. Determine a maximum safe speed (assuming current design standards) to the nearest 5 mi/h.
If a 96-inch brick sewer (n = 0.015) is laid on a slope of 0.01% is set to be rehabilitated with GIPL (n = 0.01) that will need 2-inches all around it. How much more flow, in cfs will be attained with this project
What is the final equilibrium temperature of the two bodies?
