Let's say p is the principal cost of the total (original) we can setup the equation p-.4p=40.5 => .6p=40.5 => p=67.5
So the cost without the sale is $67.50
For the original price of each pair divide this by 3.
67.5/3=22.5
Final answer:
Each pair costs $22.50 without the sale.
Hope I helped :)
The distance of the yacht from the ship is 35 km
<h3>How to determine the distance?</h3>
See attachment for the diagram that represents the given parameters.
The distance of the yacht from the ship is then calculated using the following law of cosine.
YS^2 = ST^2 + YT^2 - 2 * ST * YT * cos(T)
This gives
YS^2 = 24^2 + 12^2 - 2 * 24 * 12 * cos(155)
Evaluate the exponents and the products
YS^2 = 576 + 144 + 522
Evaluate the sum
YS^2 = 1242
Take the square root of both sides
YS = 35
Hence, the distance of the yacht from the ship is 35 km

<span><u>Answer </u>
Skew lines do not lie on the same plane.
<u>Explanation
</u>
Skew line are lines that do not meet yet they are not parallel. Skew line are such that when translated they make an angle with each other. So they cannot be said to be parallel.
