A state government is planning to construct a new bridge over a river to improve transportation infrastructure. The bridge's design includes a main span of 300 meters and two approach spans of 100 meters each. The estimated cost of constructing the main span is $2,500 per meter, while the cost of constructing each approach span is $1,500 per meter. Calculate the total cost of constructing the bridge. A) $1,050,000 B) $1,200,000 C) $1,350,000 D) $1,500,000

As in Exercise 39, find the volume of the box if four congruent squares with sides of length 6 in. are cut from the corners of a rectangular piece of poster board that is 20 in. wide by 30 in. long. Kristine creates an open box by cutting congruent squares from the four corners of a square piece of cardboard that has a length of 24 in. per side. If the congruent squares that are removed have sides that measure 6 in. each, what is the volume of the box formed by folding and sealing the flaps?

A carpenter lays out boards of lengths 8 ft, 8 ft, 4 ft, and 4 ft by placing them end to end. a If these are joined at the ends to form a quadrilateral that has the 8-ft pieces connected in over, what type of quadrilateral is formed? b If these are joined at the ends to form a quadrilateral that has the 4-ft and 8-ft pieces alternating, what type of quadrilateral is formed?

A welded support base is cut into four pieces as shown in Figure 14. What fractional part of the total length does each of the four pieces represent? All dimensions are in inches. Piece 1: . Piece 2: . Piece 3: . Piece 4: . The circle in Figure I -S is divided into equal parts. Write the fractional part represented by each of the following in Exercises 3 and 4:
