Answer:
price of senior citizen ticket is $8 and price of child ticke be $14.
The plot is as attached. the ordered pair is (8,14)
Step-by-step explanation:
Let price of senior citizen ticket be $x and price of child ticke be $y.
we are given that On the first day of ticket sales the school sold 3 senior citizen tickets and 1 child ticket for a total of $38.
Then we can write
The school took in $52 on the second day by selling 3 senior citizen tickets and 2 child tickets.
So we can write
Now solve above two equations togethere we get
price of senior citizen ticket is $8 and price of child ticke be $14.
In slope intercept form the above equation can be written as
The plot is as attached. the ordered pair is (8,14)

Imagine cutting this shape into two semi-circles and one rectangle.
------------------------------------------------------------------------------------------------------
- Each semi-circle has a diameter of 36 meters
- The radius would be <em>(36/2) = </em>18 meters.
--------------------------------------------------------------------
<em>We know the area of a whole circle which is π</em><em />
- The formula of area of a semi-circle: 1/2(π
)
<em>because a semi-circle is basically half of the whole circle!</em>
<em />
However, since we have two equal semi-circles...we can just put them together and solve for the whole circle's area.
<em>for reference: </em>
1/2(π) + 1/2(π
) = 2/2(π
) = π
----------------------------------------------------------
First, the area of rectangle: length times width = 84 x 36 = 3024 square meters
<em>Anyways, since we have to sub in 3.14 for π </em>
Area of a whole circle: (3.14 x ) = (3.14 x
) = 1017.36 square meters
-----------------------------------------------------------
3024 + 1017.36 = 4041.36 square meters
