The answer to the question
Answer:
The volume of the balloon is 18.84 inches³
Step-by-step explanation:
* Lets talk about the sphere
- Its a solid
- It has surface area = 4πr²
- It has no lateral area
- It has no faces
- It has no vertices
- It has no edges
- Its volume = (4/3) π r³
* In our problem the balloon shaped a sphere
- Its radius = 4.5 inches
- The value of π = 3.14
* Lets calculate its volume
∵ The radius = 4.5 inches
∵ π = 3.14
∵ The volume = (4/3) π r³
* Substitute the values of r and π in the formula
∴ The volume = (4/3) × 3.14 × 4.5 = 18.84 inches³
* The volume of the balloon is 18.84 inches³
Step-by-step explanation:
x - 5 < 2 (y - 8) • 1/4
x - 5 < (y - 8) / 2
2 (x - 5) < y - 8
2x - 10 < y - 8
2x - 10 + 8 < y
y > 2x - 2

Answer:
24
20
4
Step-by-step explanation:
⅘×30=24... 4×30=120, 5×30=150... 120/150
120/2=60
150/2=75
60/75= 0.8
⅘= 0.8
do the same with all of the others
