What is the present worth of the following stream of cash flows? An annuity that starts 8 years from now and pays $5,000 per year for 3 years (3 payments of $5,000). Assume 8% interest rate. (Note: nothing is paid in years 1-8. The first payment is received at the end of year 9. The last payment is received at the end of year 11.)

Unit labor costs in Germany approach the equivalent of USD 45 per hour, whereas in Britain unit labor costs are only hour. Why would such a large difference persist between two members of the EU free trade area? Britain does not participate in the EU social programs, which add to the unit labor costs of German firms. Workers in the German manufacturing sector are more productive and thus earn higher wages for time work

Text: Information for Problems 1 The exit Mach number and ratio of specific heats for a rocket nozzle are 3.0 and 1.24, respectively. The chamber temperature and pressure are 3,600 K and 880 kPa (assume these to be stagnation conditions). The molecular weight of the gas in the nozzle flow is 22.0 kg/kmol. The throat area is At = A* = 7.854x10^-3 m^2 (FYI, throat diameter 10 cm, approximately 4 inches). Calculate: 1. Nozzle expansion area ratio, A2/A*. 2. Exit temperature ratio, T0/T2, and exit temperature, T2. 3. Exit pressure ratio, P0/P2, using the temperature ratio, and the exit pressure, P2. 4. Velocity at the nozzle exit using the pressure ratio. 5. Velocity at the nozzle exit. I need help with finding the throat pressure, please.

Texts: How many molecules of THC does this 27 g represent? Part A How many moles of THC does 27 g represent? Express your answer in moles to two significant figures. (View Available Hints) n = 8.6 x 10^(-6) mol Previous Notes: Correct Important: If you use this answer in later parts, use calculations to convert the mass of a substance to the number of moles and vice versa. The molar mass in g/mol of the substance is used as a conversion factor. Molar mass uses the units of grams. Begin by converting the given mass (g) using the equivalence 1g = 1.0 g/mol. The mass given is 27 g. 2.710 The molar mass in grams per mole of any substance is equal to the formula weight in atomic mass units. The atomic masses of carbon, hydrogen, and oxygen are 12.0 amu, 1.0 amu, and 16.0 amu, respectively. By adding the 21 carbon atoms, 30 hydrogen atoms, and 2 oxygen atoms, you can find the formula weight of CHO to be 314.0 amu. Contribution of 21 carbon atoms: 21(12.0 amu) = 252.0 amu Contribution of 30 hydrogen atoms: 30(1.0 amu) = 30.0 amu Contribution of 2 oxygen atoms: 2(16.0 amu) = 32.0 amu FW of CHO = 314.0 amu Because CHO has a formula weight of 314.0 g/mol. In other words, 1 mole of CHO has a mass of 314.0 g. Using the molar mass as a conversion factor, we can convert 2.710 g of CaHO to the number of moles. Moles of CHO = 2.710 g / 314.0 g/mol = 0.0086 mol CHO Part B How many molecules? Express the number of molecules to two significant figures. (View Available Hint(s))
