The equation of the perpendicular bisector.
First, calculate the midpoint of the given endpoints
Open bracket
Next, determine the slope of the given endpoints.
Next, calculate the slope of the perpendicular bisector.
When two lines are perpendicular, the relationship between them is:
In this case:
So:
Since the slope is 
, the equation is:
Where:
Recall that:
So:
Hence, the equation is:
For this case, what you must do is take out the area of two triangles and add it to the area of a rectangle to find the total area.
We have then:
Triangle area:
A = (1/2) * ((13-9) / (2)) * (10) = 10 in ^ 2
Rectangle area:
A = (9) * (10) = 90 in ^ 2
Total area:
At = 2 * (10) + 90 = 110 in ^ 2
answer:
110 in²

Answer:
There are 3 green marbles in the box.
Step-by-step explanation:
15% = 0.15
To figure out how much 15% of 21 is, you must multipl the decimal form of the percentage by the whole number. This will give you how much of that number that percentage is.
0.15 * 21 = 3.15
But you can't have 0.15 of a marble, so you must round as well.
