Answer:

The percentage of the markup is 82%

Step-by-step explanation:

In this question, we are asked to calculate the percentage of mark up. This is simply calculating the percentage of the profit margin.

firstly to be able to calculate this percentage, we need to know the value of the profit margin itself.

mathematically, the profit margin is selling price - cost price

From the question, the selling price is $1 while the cost price is 55 cents

The profit margin is thus $1 - 55 cents = 45 cents

We now proceed to calculate the percentage profit

mathematically, that is profit/cost price * 100%

That would be 45 cents/55 cents * 100 = 9/11 * 100% = 81.8 approximately 82%

Komok [63]

Answer:

a) Triangle

b) Rectangle

Step-by-step explanation:

A triangular prism that has an equilateral base and a height with the same length as the base of the prism.

a) Shape from horizontal slicing

A plane parallel to the base of a triangular prism will  intersect a cross section that is the same shape as its  bases. So the cross section of the horizontal slicing is an equilateral triangle (all the sides of the triangle are equal).

b) Shape from vertical slicing

If the triangular prism is sliced vertically, the resulting shape would be a rectangle with a length that is the same as the base of the prism.
