Write a system of equations to describe the situation below, solve using any method, and fill in the blanks. Nicole and Josie are both selling cookie dough for a fundraiser. Although Nicole has already sold 4 tubs, Josie hasn't sold any yet. If Nicole starts selling 5 tubs per day and Josie begins selling 6 tubs per day, they will eventually sell the same amount of cookie dough. How many tubs will each sell? How many days will that take?

Nicole and Josie will each sell
tubs of cookie dough in
days.

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
