Answer:
x = 4
Step-by-step explanation:
180 = 102 + 24x - 18
- 102 - 18 = 84
- subtract 84 from both sides
- 96 = 24x
- divide both sides by 4
- 4 = x
Given:
Big cone : diameter = 12 cm ; height = 18 cm ; base = 14 cm
Small cone: diameter = 12 cm ; height = 6 cm ; base = 14 cm
Volume of a cone-shaped container = π r² h/3
Big cone:
V = 3.14 * (6cm)² * 18cm/3
V = 3.14 * 36cm² * 6cm
<span>V = 678.24 cm³
</span>Small cone:
V = 3.14 * (6cm)² * 6cm/3
V = 3.14 * 36cm² * 2cm
<span>V = 226.08 cm³
</span>Big cone - small cone = volume of water
678.24 cm³ - 226.08 cm³ = 452.16 cm³
Answer:
Step-by-step explanation:
These are physical measurements, which must be zero or greater. These restrictions are the reason for your having a total of four inequalities.
The answer is C.
Proof:
8×4-(2×3+8)÷2
=32-(6+8)÷2
=32-14÷2
=32-7
=25
