Answer:
Step-by-step explanation:
2. 9a +4c=43
a+c=7
The total tickets for adults and children = 7 (a+c =7) 7 people in all
price for adult = $9 (9a) Price per child =$4 (4c)
total price =$ 43
9a +7c = 43

Hello!</h2>
The answer is:
1017.88 square feet are blue.
<h2>Why?</h2>
To calculate how many square feet are blue, we need to calculate the area of the bottom of the circular swimming pool.
We need to remember that we can calculate the area of any circle using the following formula:
![Area_{circle}=\pi radius^{2}](https://tex.z-dn.net/?f=Area_%7Bcircle%7D%3D%5Cpi%20radius%5E%7B2%7D)
Now, we know that the diameter of the bottom is equal to 36 feet, so, we can calculate the radius of the bottom using the following formula:
![diameter=2radius\\\\radius=\frac{diameter}{2}](https://tex.z-dn.net/?f=diameter%3D2radius%5C%5C%5C%5Cradius%3D%5Cfrac%7Bdiameter%7D%7B2%7D)
So,
![radius=\frac{36feet}{2}=18feet](https://tex.z-dn.net/?f=radius%3D%5Cfrac%7B36feet%7D%7B2%7D%3D18feet)
Then, calculating the area we have:
![Area_{bottom}=\pi radius^{2}=\pi 18ft^{2}=1017.88ft^{2}](https://tex.z-dn.net/?f=Area_%7Bbottom%7D%3D%5Cpi%20radius%5E%7B2%7D%3D%5Cpi%2018ft%5E%7B2%7D%3D1017.88ft%5E%7B2%7D)
Hence, we have that 1017.88 square feet are blue.
Have a nice day!
first you would put the expression in a fraction for
180/460
you already know that the both numbers are divisible by 2
- so the answer would be 90/230 but we are still no done because these values are divisible by three
the rule to prove that the number is divisible by three is when you add the digits of the number for example 333. 3+3+3=9 and nine is divisible by nine
THE ANSWER IS:::::::: 90/230
