Tape is used to seal insulation around 12 pieces of ducting. Each piece ofduct needs two strips of tape. The first strip of tape measures 1.84 meters.The second strip measures 55 centimeters. The strips are cut from a 75-meter-long roll of tape. How much tape will be left after the 12 pieces ofducting are sealed?

R Value: Wall: 0.961m2k/w Floor: 0.676m2k/w Roof: 0.7465m2k/w In a table format show with calculations and research how much money you can save by installing a 115mm layer of insulation (R2.9) in your walls, floor and ceiling over a 5 and 10 year period. Consider the capital costs. Hint: State the current R value of each component. Convert to U value. Calculate new R value of each component (walls, floor and ceiling). Convert to U value. Use Q(W)=A*(change in U)*temperature change. Determine price for installation of new insulation. Determine price saved based on less heat loss through each component separately, then add all values together, and calculate per 5 years and per 10 years. Present all of this information in a table. You do not need to draw any diagrams, simply add the R value in series with your current components R values. Assume the energy cost is 25 cents kWh
