It would be 2.1 hours or about 2 hours.
It says the train travels about 2118 miles per 8 miles. So, divide 2118 by 8, which gives you 264.75 (when you see the word PER it usually indicates to divide). That gives you part A.
Then, you divide 560, (which is t<span>he distance between Columbus, Ohio, and New York) by 264.75 to see how many hours it took, which gives you 2.1152030217...., which simplifies to 2.1. Which gives you the answer for B.
So,
A is 560 and
B is 2.1 or 2

Answer:
Step-by-step explanation:
Let the I line be PQ and II line be RS
Direction ratios of PQ = (9,0,0) and direction ratios of RS = (0, -4, -12)
Distance between skew lines
=(a1-a2).(b1xb2)/|b1xb2|
where a1 and a2 are points
Here a1-a2 = (-3,2,-4) taking P and Q as points.
b1 = (9,0,0) and b2 = (0,-4,-12)
Shortest Distance = (a2-a1).(b1xb2)/|b1xb2|
De![\left[\begin{array}{ccc}-3&2&-4\\9&0&0\\0&-4&-12\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-3%262%26-4%5C%5C9%260%260%5C%5C0%26-4%26-12%5Cend%7Barray%7D%5Cright%5D)
Numerator = -9(-24-16)=360
Denominator vector = i(0)-j(-108)+k(-36)
Modulus of vector =\sqrt{108^2+36^2} =36\sqrt{10}
Hence Shortest distance = \sqrt{10}
The chart shows a production possibilities schedule for Sabrina’s Soccer.
Combination: Soccer balls: Soccer nets:
A 10 0
B 8 1
C 6 2
D 4 3
E 2 4
F 0 5
Which statement correctly explains the chart?
A. The opportunity cost of producing one soccer net is eight soccer balls.
B. The opportunity cost of producing two soccer nets is two soccer balls.
C. The opportunity cost of producing two soccer balls is one soccer net.
D. The opportunity cost of producing four soccer balls is three soccer nets.
The opportunity cost of producing two soccer balls is one soccer net.
Answer: Option 3
<u>Explanation:</u>
Opportunity cost is when a particular option is chosen from the alternatives given, the opportunity cost is the cost incurred by not enjoying the benefit associated with the best alternative choice.
The problem of the opportunity cost occurs because the resources given in the economy are limited in availability and there fore because of that there has to be some choices that are to be made among the alternatives given in the economy.
In this example it shows that for producing two soccer balls, the opportunity cost is one soccer net.
