what is the proper height to hang draperies?

A new road is proposed and the Surveyor provided the information below. A grade sheet for TOP - OF - CURB values is required. You are asked to provide the following information; i) Difference in elevation from the C/L to the bottom of the curb face , ii) The height of the top of the curb face above the C/L , iii) cut or fill value at 2+82.50 , iv) cut or fill at 3+10.00 , v) cut or fill at 4+00.00 , and vi) cut or fill at 4+32.00 .

NOTE: Centreline elevation at station 2+82.50 = 155.30m. When writing cut or fill values put - or + for cut or fill respectively. e.g if the cut is 0.90,  your answer should be -0.90.

Four key elements must be coordinated in order for any campaign to be successful: the Message, the Machine, the Media, and Money.

In Texas, these elements must be reconciled with the prevailing political culture of Traditionalism and Individualism. Has the rise of Interactive Social Media affected the way in which campaigns are conducted in Texas? Has campaigning become easier? More difficult? More expensive? Less expensive? Please explain your answer.

A tank contains 360 gallons of water and 50 oz of salt. Water containing a salt concentration of 1 6 (1 + 1 4 sin t) oz/gal flows into the tank at a rate of 8 gal/min, and the mixture in the tank flows out at the same rate. The long-term behavior of the solution is an oscillation about a certain constant level. a) What is this level? b) What is the amplitude of the oscillation? (Round your answers to two decimal places.)
