Civil/Environmental Engineering

A civil engineer involved in construction requires 4800, 5810, and 5690 m 3 of sand, fine gravel, and coarse gravel, respectively, for a building project. There are three pits from which these materials can be obtained. The composition of these pits is

Sand
%
Fine Gravel
%
Coarse Gravel
%
Pit 1 52 30 18
Pit 2 20 50 30
Pit 3 25 20 55

How many cubic meters must be hauled from each pit in order to meet the engineer's needs?

Two construction materials industries J&J cement and B&B Bitumen are situated side by side. Each year, B&B bitumen purchases about 501 tonnes of lime kiln dusts produced by J&J cement to use as filler in bitumen at $10/tonne. This avoids B&B Bitumen to purchase 455 tonnes hydrated lime per year for filler materials. The market price of hydrated lime is 40/tonne. What is the annual economic benefit of B&B Bitumen from this industrial symbiotic relationship?(Dont write $ sign. Just write the whole number what you get, dont covert to kilo or million. For example, write 500,000, dont write 500k or 0.5 million. Calcualte answer to 0 decimal places)
A husband and wife take turns pulling their child in a wagon along a horizontal sidewalk. Each exert a constant force pulls the wagon through the same displacement. They do the same amount of work,but the husband's pulling force is directed 58grades above the horizontal , and the wife's pulling force is directed 38 grades above the horizontal. the husband pulls with a force whose magnitude is 67N. WHat is the magnitude of the pulling force exerted by his wife? 1)sketch of the problem including everything? 2) 3 laws and principle in this problem?
