A swimming pool is being filled with water. The diameter of the pool is 27 feet, and the height if 4 feet. Which formula represe
2 answers:
If you are using the word diameter, I am going to assume that the pool is round. A round pool represents the shape of a cylinder. The volume for a cylinder is 
. Diameter is twice the radius, so our radius is half of 27 which is 13.5 feet. So our formula is 
. That's the forumula for it. That actual volume measure is 
, or multiplying in pi as 3.14, it's 2289.06 cubic feet.

Answer:
no solution
Step-by-step explanation:
Given the 2 equations
y = x + 4 → (1)
- x + y = - 5 → (2)
Substitute y = x + 4 into (2)
- x +
x + 4 = - 5 , that is
4 = - 5 ← not possible
This indicates the system has no solution
Question:
You are ordering short-sleeve shirts (x) for $10 and long-sleeve shirts (y) for $15. Your budget is $300. Write the equation and find the intercepts.
Interpret their meaning.
Answer:
The x-intercept shows that you can buy 30 short-sleeve shirts and 0 long-sleeve shirts.
The y-intercept shows that you can buy 20 long-sleeve shirts and 0 short-sleeve shirts.
Step-by-step explanation:
Given
$10 per short sleeve
$15 per long sleeve
Budget = $300
The above can be represented as:
Total Cost of Short Sleeve + Total Cost of Long Sleeve = Budget
i.e.
To solve for the y intercept, we set x to 0
Divide through by 15
<em>This implies that, you can buy 0 short sleeves and 20 long sleeves</em>
To solve for the x intercept, we set y to 0
Divide through by 10
<em>This implies that, you can buy 0 long sleeves and 30 short sleeves</em>
