In a video game, players form teams and work together to earn as many points as possible for their team. Each team can have betw
stealth61 [152]

Answer:

1. 2 ≤ n ≤ 4

2. 4 * 20

3. T < 80

4. (2 * 4) + (4 * 3)

5. 16 ≤ P ≤ 32

Note: The quantities described are as follows:

1) the allowable number of players on a team  

2) the number of points,  , Han's team earns in one round if every player earns a perfect score  

3) the number of points,  , Han's team earns in one round if no players earn a perfect score  

4) the number of players,  , in a game with six teams of different sizes: two teams have 4 players each and the rest have 3 players each

5) the possible number of players in a game with eight teams

Step-by-step explanation:

1. Let the number of players be n

Since each team can have between 2 and 4 players

n ≥ 2 or 2 ≤ n, and n ≤ 2

Therefore, the allowable number of players on a team   is given by 2 ≤ n ≤ 4

2) There are four players in Han's team and a perfect score is 20

Therefore, the number of points Han's team earns in one round if every player earns a perfect score   is given by 4 * 20

3) There are four players in Han's team

Total score if each player in Han's team earns a perfect score is 4 * 20 = 80

Let the total score of Han's team be T

Therefore, the number of points, Han's team earns in one round if no players earn a perfect score   is given by T < 80

4) If two team have 4 players, it is given by 2 * 4

If the rest four teams have 3 players each, it is given by 4 * 3

Therefore, the number of players in a game with six teams of different sizes: two teams have 4 players each and the rest have 3 players each  is given by (2 * 4) + (4 * 3)

5) Let the possible number of players in a game with be P

Maximum number of players in eight teams = 4 * 8 = 32

Minimum number of players in eight teams = 2 * 8 = 16

P ≤ 32 and P ≥ 16 or 16 ≤P

Therefore, the possible number of players in a game with eight teams  is given by 16 ≤ P ≤ 32

Varvara68 [4.7K]

Answer:

3.69 hours

Step-by-step explanation:

y = 80.25x + 78.75

y = 95.75 + 40

85.25x + 78.75 = 95.75 + 40

-85.25x   -40        -85.25x  -40

38.75/10.5 = 10.5x/10.5

3.690476190..... = x

rounding

3.69 = x

Simplify -12x^4/x^4+8x^5
alexgriva [62]

Answer:

OPTION A: $ \frac{12}{1 + 8x} $, where $ x \ne - \frac{1}{8} $.

Step-by-step explanation:

Given: $ \frac{- 12x^4}{x^4 + 8x^5} $

Taking $ x^4 $ common outside in the denominator, we get:

$ = \frac{-12x^4}{(x^4)(1 + 8x)} $

$ x^4 $ will get cancelled on the numerator and denominator, we get:

$ = \frac{-12}{1 + 8x} $

we know that the denominator can not be zero.

That means, 1 + 8x $ \ne $ 0.

$ \implies 8x \ne -1 $

$ \implies x \ne \frac{-1}{8} $

So, the answer is: $ \frac{-12}{1 + 8x} $, where $ x \ne \frac{-1}{8} $.
