Answer: Number of sand bags are 105
Step-by-step explanation:
Alright, lets get started.
The diameter of pool is given as : 
The radius of pool will be : 
So the area of the pool will be:
Area = 
Area = 
Area = 
Area = 
3 square feet is covered by 1 sand bag, so
314.16 square feet will be covered by : 
So, no of sand bag = 
Rounding off to nearest number
Number of sand bags are 105 : Answer
Hope it will help :)
Answer:
True
Explanation:
First of all its necessary remember that a linear system is a compound of multiple equations that involve variables.
<h2>Existence:</h2>
Depending on the number of equations and the number of variables, you could determine if the linear system has a solution or not. There are 3 possibilities:
- If the linear system has more equations than variables could exist infinite answers.
- If the linear system has more variables than equations, it is considered an undetermined system and you neer more information to solve it.
- If the linear system has the same number of equations and variables, the system is consistent and has at least one solution.
<h2>
Uniqueness:</h2>
If possibility 3 is presented, it becomes necessary know if its the only one solution or exists more than one solution.

The same way you add and subtract any pair of fractions. You need to make sure the denominators are equal. Once they are equal, you can add or subtract the numerators and place the result over the common denominators.
⭐️- Remember that slope formula is y=mx+b
1. Know that the m is (-3)
2. 4=(-3)(9)+b
3. 4=(-27)+b
4. b=31
5. y=(-3x)+31
6. y=3x-31*
*whenever it is finding a perpendicular, you switch the signs; when it is finding a parallel, you leave it alone
