The length of a planet's orbit around a star is approximately 17,680,000 km. It takes the planet about 860 Earth days to complete a full orbit.
What is the planet's average speed in kmh 1 to 3sf?

856.59 km/h

Step-by-step explanation:

Length of a planet's orbit around a star = 17,680,000 km.

Days to complete full orbit = 860 days

Number of hours to complete full orbit = 860 × 24 hours = 20640 hours

The planets average speed in km/h will be:

= Distance / Time

= 17,680,000 / 20640

= 856.59 km/h

Note: 24 hours = 1 day

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !
