Answer:
I'm pretty sure he or she are right^^idk
Step-by-step explanation:
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.
1 trillion is 10^9.
Thus, 21 1/2 trillion is 21 1/2 times 10^9, or 2.15 times 10^10
Hope this helps. If not, ask for clarification.
Answer:
B. w = 4
Step-by-step explanation:
As we know, in a parallelogram length of opposite sides are equal.
so, AD = BC
⇒ 4w - 5 = 7w - 17
⇒ 12 = 3w
⇒ w = 4
