What is the reason for using two different scales on the horizontal and vertical axes in a road section (profile) drawing ? 40 - O a) For ease of application O B) Due to the level difference between the horizontal and vertical axes. O C) Due to the level difference between the horizontal and vertical axes. D) Because the horizontal axis is much larger than the vertical axis, O TO) To express length and cross-section separately and create cross-section

Show and draw plotted points of the cross-section of roadway each station. Calculate thefollowing:1. Total number of man-days to finish the earthwork job2. Total cost of machine rentals to finish the earthwork job.In the inventory of available heavy equipment on site are three (3) hydraulic excavators with bucket payloadcapacity each of 0.76m3 and one (1) hydraulic excavator with bucket payload capacity of 1.15m3. The hourlyproduction of each excavator with 100% efficiency are 149m3 and 196m3 respectively. Daily machine rentalfees for smaller capacity is 1,200 pesos while bigger capacity costs 2,200 pesos. Daily machine operationsis limited to 8 hours.
