Answer:

  the distance between the points is about 9.2 units

Step-by-step explanation:

It is well you should not understand it. <em>No question is asked</em>.

__

The answer choices suggest you are to find the distance between the two points. There is only one choice in a reasonable range: 9.2 units.

Each point is more than 2 units from any axis, so 2 units is clearly not the answer. The size of the graph is much less than 81 units, so clearly that is not the answer.

The difference of coordinates in the x-direction is 6; in the y-direction the difference is 7 units. The distance between the points will be more than the longest of these (7) and less than about 1.5 times that (10.5). Only one choice is in this range: 9.2 units.

__

The Pythagorean theorem is used to calculate the distance between points. The distance is considered to be the hypotenuse of a right triangle with legs of lengths equal to the differences of coordinates. Here, that means the distance (d) is ...

  d² = 6² + 7² = 36 +49 = 85

  d = √85 ≈ 9.2 . . . . grid squares, or "units"

The Markup percentage is mathematically given as

M=42%

<h3>What is Mark up percentage?</h3>

The markup % may be determined by dividing the gross profit of a unit (the difference between its sales price and the amount it cost to create or buy for resale) by the amount that unit originally cost. If a product sells for $12 but only costs the corporation $8 to produce it, the markup percentage for that product is 50%, which can be calculated as (12 - 8) divided by 8.

Generally, the equation for is Total cost price mathematically given as

TCP= Pay+insurance

Therefore

TCP=35.5*1.6

TCP=284/5

Generally, the equation for is Total selling price mathematically given as

TSP=89.99+7.99

TSP=97.98

In conclusion, Mark up percentage is

M=\frac{SP-CP}{SP}*100\\\\

M= \frac {97.98 - (284/5) }{97.98}   *100

M=0.4202898551*100

M=42%

PolarNik [594]
So..hmm check the picture below

the pyramid is really just 4 triangles and 1 square at the bottom, all stacked up to each other at the edges

get the area of the square bottom, is just a 6x6 square,  thus the name of the pyramid

and get the area of each triangle, notice the base  is 6, the altitude or height is 9

and add them all up, that's the surface area of the pyramid
