During the chess championship each player played with each other two games. players who win in a game were awarded 1 point, while those who draws were given a half-point. losing a game was worth zero points. the three best players scored together 24 points, which is twice less than the sum of points of all other players scored. how many players were participating in the championship?

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

c

step-by-step explanation:

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

company a

step-by-step explanation:
