<span>11,550 km has to be changed to 11,550,000 meters
G · m · t² = 4 · π² · r³ we can change that to
</span>t² = (4 · π² · r³) / <span>(G · m )
t^2 = 4*PI^2*r^3 / (G*m)
</span>t^2 = 4*PI^2*<span>(11,550,000)^3 / 6.67*10^-11*5.98*10^24kg

</span>and its orbital distance it travels is 11,550 * 2*PI = 70,050 kilometers
Therefore, it is traveling at 70,050 km / 12,350 second which equals
5.67 km per second which <em>is 5,670 meters per second.</em>

Answer:
7 miles
Step-by-step explanation:
You have total of $20
We subtract $2.50 from it since it is the base charge, so now we have:
20 - 2.5 = $17.50
This is for the number of miles at $2.50 PER MILE. To find the number of miles we can travel for this, we have to divide the amount we have (17.5) by the rate per mile (2.5), so we have:
17.5/2.7 = 7
So for a total of $20, we can travel 7 miles (without tip)
Answer:
D) 2x² + x - 10
Step-by-step explanation:
First, distribute the negative sign to all terms within the second parenthesis:
- (4x - x² + 6) = -4x + x² - 6
Next, combine like terms:
5x + x² - 4 - 4x + x² - 6
(x² + x²) + (5x - 4x) + (-4 - 6)
2x² + x - 10
2x² + x - 10 , or D) is your answer.
Answer: 3/8
Step-by-step explanation:
1/2 is also 4/8 so you subtract 4/8 from 7/8 to get 3/8
