a. (2 points) How many small and large offices should thedeveloper build?

b. (4 points) What is the total optimal monthly revenue?

c. (2 points) If the developer implements the optimal solution,what amount of square footage would remain unused?

d. (5 points) What is the impact on the optimal allocation ofoffices and the objective function value if small offices can berented for \$800 per month rather than \$600 per month?

e. (2 points) What impact would an increase in 52,800 sq. ft ofadditional footage have on the optimal objective functionvalue?

f. (5 points) What impact will an increase in the monthly rentalof small offices to \$650 and simultaneous decrease to \$800 in themonthly rental of large offices have on the current optimalsolution and the objective function value?

A real estate developer is planning to build an office complex. There are three office sizes currently under consideration: small, medium, and large. Small offices can be rented for \$600 per month, medium offices can be rented for \$750 per month, and large offices can be rented for \$1,000 per month. Each small office requires 600 square feet, each medium office requires 800 square feet, and each large office requires 1,000 square feet. The current plot of land available to the developer is 100,000 square feet. The developer wants to ensure that the office complex has at least 3 units of each office size. Moreover, zoning restrictions limit the total number of offices to 50. The developer solved this problem such that he could accrue maximum rent from the small, medium, and large offices he builds.

## (Solved) : 18 Marks 30 Questions Statement Must Completely True Respects Considered True Statement Q40747219 . . .

All Questions are in regard to AutoCad.

I. (18 marks for 30 questions). A statement must be completely true in all respects to be considered a TRUE statement, otherwise it is FALSE. A True or B False 1) Lettering is a component in an Engineering Drawing. 2) An ellipse can be sketched using a rectangle that encloses it and dividing the rectangle in to 4 quadrants (smaller rectangles). Centre lines in a drawing are as thick as continuous lines drawn to show edges. 4) Although manual method is not used very often these days, an engineering drawing can be dra & manually to a reasonable accuracy. 5) It is useful to have snap spacing to be half the size of grid spacing. 6) EXPLODE command is used to “split” a single object in to several objects. One advantage of PLINE is its PEDIT option that provides you many useful options. 8) MLINE provides two parallel lines that could be used in applications but the disadvantage is that it cannot provide more than 2 parallel lines. 9) XLINE refers to MLINE and PLINE 10) Status Bar can be customized to add or drop buttons.

## (Solved) : 10 Points River Flow Upstream Gauging Station Measured 1250 Ms Another Gauging Station 25 Q40762713 . . .

Hello, coul you please help to solve the above problems?Warm regards.I. (10 points) The river flow at an upstream gauging station is measured to be 1250 ms, and at another gauging station 2.5 km downstream, the discharge is measured to be 700 m’s at the same instant of time. If the river channel is uniform with a width of 250 m estimate the rate of change in the water surface clevation in meter per hour. Is it rising or falling? 2.
