Step-by-step explanation:Regular polygons are shapes made of straight lines with certain relationships among their lengths. For instance, a square has 4 sides, all the same length. A regular pentagon has 5 sides, all the same length. For these shapes, there are formulas for finding the area. But for irregular polygons, which are made of straight lines of any length, there are no formulas, and you need to be a little creative to find the area. Fortunately, any polygon may be divided into triangles, and there is a simple formula for the area of triangles.
Label the vertices (points) of the polygon starting with 1 at an arbitrary vertex and continuing clockwise around the polygon. There should be as many vertices as there are sides. E.g. for a pentagon (five sides) there will be five vertices.
Draw a line from vertex 1 to vertex 3. This will make one triangle, with vertices 1, 2, and 3. If there are only 4 sides, it will also make a triangle with vertices 1, 3 and 4.If the polygon has more than 4 sides, draw a line from vertex 3 to vertex 5. Continue in this way until you run out of vertices.
Compute the area of each triangle. The formula for the area of a triangle is 1/2 * b * h, where b is the base and h is the height.
Add up the areas, and this is the area of the polygon.
Answer:
It seems there's more information in you question that you haven't posted.
7 months = 7 * (365/12) = 213 days
The half-life of chromium 51 is 27.7 days.
After 7 months, chromium 51 will have undergone 7.69 half-lives.
To solve for the ending amount we'll use the formula:
Ending Amount = Beginning Amount / 2^n where 'n' = # of half-lives
We'll say the beginning amount =1
Ending Amount = 1 / 2^7.69
Ending Amount = 0.0048426082
Basicaly if you started with 1 gram of chromium 51, after 7 months you would have 0.0048426082 grams.

Answer: The total number of games sold by the GameStop is 14. That is 5 games of $43 and 9 games of $30.
Step-by-step explanation:
Considering some games of $43 were sold and others for $30 were also sold in arriving at the total of $485 sold.
If 5 games of $43 were sold it gives $215.
To get the difference, you subtract the amount sold for $43 from the total.
$485 - $215 = $270
To arrive at how many $30 games were sold;
$270 ÷ $30 per game = 9 games
Therefore, 5 games of $43 combined with 9 games of $30 gives a total of 14 games.
Answer:
Yes
Step-by-step explanation:
85, 85, 90, 90, 95, 95, 100, 100, 150
Median: 95
Q1: (85+90)/2 = 87.5
Q3: 100
IQR: Q3 - Q1 = 100 - 87.5 = 12.5
1.5 × IQR = 18.75
Outliers are outside the interval:
[Q1 - 1.5×IQR, Q3 + 1.5×IQR]
Q3 + 1.5IQR = 100 + 18.75
= 118.75
Since 150 > 118.75, it is an outlier
