Answer:
0.19 cents is the unit price
Step-by-step explanation:
4.75 divided by 25 is .19
<u>Define x:</u>
Let the cost of the ball be x.
Ball = x
Bat = x + 0.1
<u>The total cost is $1.10:</u>
x + x + 0.1 = 1.1
2x + 0.1 = 1.1
2x = 1
x = 0.5
<u>Find the cost of the bat and the ball:</u>
ball = x = $0.50
bat = x + 0.1 = 0.5 + 0.1 = $0.60
Answer: The ball cost $0.50
The surface area of a sphere is A = 4π R²
The volume of a sphere is V = (4/3) ( π) (R³)
The ratio of (surface area) to (volume) is
4 π R² / (4/3) (π) (R³)
Divide top and bottom by 4π : R² / (1/3) (R³)
Multiply top and bottom by 3: 3 R² / R³
Divide top and bottom by R² : 3 / R .
For the Earth,
A / V = (3) / (3,960 miles) =<em> 0.00076 per mile </em>(rounded)
