Answer: THIRD OPTION.
Step-by-step explanation:
Given the following inequality:
You can follow these steps in order to solve it:
1. Apply Distributive property on the left side:
2. Add 15 to both sides of the inequality:
3. Finally, divide both sides of the inequality by 3:
The symbol is 
means "Greater than or equal to", and indicates that 7 is include in the solution.
Therefore, the solution can be expressed as:
Now you must mark this point with a closed dot on the number line and shade everything to the right.
Answer:
Step-by-step explanation:
<h3>Part B</h3>
Assumed the dimensions of the top and bottom parts are identical.
Since the cylindrical part has total height of 1.8 cm and the hemisphere volume is transferred to bottom part and the cone part is still full, the value of h is the difference of the total height of cylinder and full part of the top section of cylinder:
- h = 1.8 cm - 0.3 cm = 1.5 cm
<h3>Part C</h3>
Find the volume of sand in the bottom part. It consists of a hemisphere and a cylinder of 1.5 cm height.
- V(cylinder) = πr²h = 3.14*(2.6/2)²*1.5 ≈ 7.96 cm³
- V(hemisphere) = 2/3πr³ = 2/3*3.14*(2.6/2)³ ≈ 4.6 cm³
<u>Total sand in the bottom part:</u>
<u>Time taken:</u>
- 12.56 / 0.05 = 251.2 seconds = 4 min 11.2 seconds
