To minimize the cost, we take the straight distance from the refinery to the other side of the river as 2 km. Also, the 7 km will be the distance that has to be traveled by the pipeline in land. The total cost, C, is therefore,
total cost = (2 km)($800,000/km) + (7 km)($400,000 /km)
total cost = $4,400,000
Thus, the total cost of the pipeline is approximately $4,400,000.00.

I hope this helped! This is because the division of numbers and factors are equal to this.
For question 6 the answer is 100 because a quarter of a circle is 90 degrees
Answer:
Alternate exterior angles : ∠g = ∠b , ∠h = ∠a (opposite sides and on outer side)
Alternate interior angles : ∠c = ∠f , ∠e = ∠d (opposite sides and on inner side)
Consecutive interior angles : ∠c = ∠e , ∠d = ∠f (same sides and on same line)
Corresponding angles : ∠e = ∠a, ∠f = ∠b, ∠g = ∠c, ∠h = ∠d (same sides on the line)
Linear pairs : ∠c and ∠e, ∠d = ∠f, (they add to 180)
Vertical angles : ∠c =∠b, ∠d = ∠a, ∠g=∠f, ∠e = ∠h (vertical angles)
