x = 9/10 - 1/5 = 7/10

The mass of the moon is 7.36*10^25 grams to the nearest tenth how many moons would it take to equal the mass of earth
trapecia [35]

Nearly 81 moons will be required to equate the mass of moon to the mass of earth.

Step-by-step explanation:

Mass of earth is 5.972*10^24 kg.  

Mass of the moon is 7.36*10^25 g = 7.36*10^22 kg

As mass of the Earth is given as 5.972 * 10^24 kg and mass of the moon is given as 7.36 * 10^22 kg, then the number of moons required to make it equal to the mass of earth can be calculated by taking the ratio of mass of earth to moon.

 Mass of Earth = Number of moons * Mass of Moon

Number of Moons = Mass of Earth/Mass of moon

Number of moons = 5.972 * 10^24/7.36*10^22= 81 moons.

So nearly 81 moons will be required to equate the mass of moon to the mass of earth.

If f(1) =7 and f(n)=-5f(n-1)-n<br><br> then find the value of <br> f(4)
jolli1 [7]

Answer:

-914

Step-by-step explanation:

f(n)=-5f(n-1)-n

f(2)= -5f(1) -2 = -5(7) - 2 = -37

f(3) = -5f(2) - 3 = -5(-37) - 3 = 182

f(4) = -5f(3) - 4 = -5(182) - 4 = -914

There are 12 teams in the Jayhook Hockey League. Each team plays every other team twice per season, once at home and once away f
zvonat [6]

Answer:

Each team played 22 games.

Step-by-step explanation:

There are 12 teams in the league, so each team has 11 rival teams. Since each team will play against a rival team twice, that means that each team will need to play 11 x 2 = 22 games per season. Of these 22 games, 11 games will be played at home while 11 games will be played away from home.

We can calculate this by using the following formula:

Total number of games played by each team = (n - 1) x 2, where n is the total number of teams in a league.
