Answer: C, E, F
Step-by-step explanation:
- Plug in the "x" and "y" values from the ordered pairs into the equation.
- For A: 3 =
→ 3 ≠ 1 → A is eliminated.
- For B: 5 =
→ 5 ≠
→ B is eliminated.
- For C: 2 =
→ 2 = 2 → C satisfies the equation.
- For D: 10 =
→ 10 ≠
→ D is eliminated.
- For E: -1 =
→ -1 = -1 → E satisfies the equation.
- For F: 3 =
→ 3 = 3 → F satisfies the equation.
- Therefore, C, E, and F are the answers.
Answer:
32901 gallons
Step-by-step explanation:
First, we find the volume of the cylindrical water tank when it is full.
The volume of a cylinder is given as:
V =
where r = radius and h = height of the cylinder
The diameter of the tank is 20 feet, hence, its radius is 10 feet.
Volume, V, is therefore:
V =
This is the volume of the tank, when it is full.
When it is 70% full, the volume will be:
1 cubic foot () is 7.48 gallons.
Therefore, the volume of the 70% full tank in gallons will be:
4398.23 * 7.48 = 32901.05 gallons ≅ 32901 gallons
The tank contains 32901 gallons of water.
