Answer:
15 weeks
The amount of money is 270
Step-by-step explanation:
You: 60 +14x
Sister: 120+10x
Set them equal to each other
60+14x = 120+10x
Subtract 10x from each side
60+4x= 120
Subtract 60 from each side
4x= 60
Divide by 4
4x/4 = 60/4
x = 15
15 weeks
The amount of money is 120+10*15 = 120+150 = 270

Answer:
Surface area = 1808.64in² and volume is 7234.56in³
Step-by-step explanation:
The figure above is a sphere, and it has a diameter of 24in
Radius = ?
Radius = diameter / 2
R = 24 / 2
R = 12in
Surface area of of sphere = 4πr²
Volume of a sphere = 4/3 πr³
π = 3.14
1. Surface area = 4 * 3.14 * 12²
Surface area = 4 * 3.14 * 144
Surface area = 1808.64in²
2. Volume of the sphere = 4/3πr³
Volume = 4/3 * 3.14 * 12³
Volume = 4/3 * 3.14 * 1728
Volume = 7234.56in³
The surface area of the sphere is 1808.64in² and the volume is 7234
56in³
