Answer:

D.

Step-by-step explanation:

Set this up as a ratio with #parts of tank on top and #minutes on the bottom and then solve it as a proportion with x being the unknown number of minutes in the second ratio.

\frac{\frac{5}{9} }{2}=\frac{1}{x}

Notice the 1 in the numerator of the second ratio.  This is because a whole tank is represented by 9/9 which is the same thing as 1.

Cross multiply to solve for x:

\frac{5}{9}x=2(1)

To solve for x we will multiply both sides by 9/5:

(\frac{9}{5})(\frac{5}{9})x=2(\frac{9}{5})

9/5 and 5/9 cancel each other out when multiplied leaving simply "x" on the left.  And multiplying on the right:

x=\frac{18}{5}

which divides to 3.6 minutes

The game that is  used for the scenario above in terms of fair play is  using a balloon. Here, the player will hit the balloon.

<h3>What is the scenario under the balloon game?</h3>

The rule of play are:

This is a classic game with simple rules which are:

  • Each player to hit the balloon up and it bonce into the air but when one should not allow it to touch the ground.,
  • Players would be tied together in twos and they will juggle a lot of balloon and it have to be more than 1 balloon with one of their hands tied to their back.

A scenario of the worksheet game whose expected value is 0 is given below:

Assume that it costs about $1 for a player to play the billon game and as such, if  the player hits a balloon, they will be given $3. what can you say. Can you say that it this game is fair or not? and who has the biggest advantage.

Solution

Note that a  game is ”fair” if the expected value is said to be 0. When a player is said to hits a balloon, their net profit often increase by $4.  So when the player do not hit a balloon, it drops to $1.

(4)(0.313) + (-1)(0.313)

= 0.939 approximately

Thus, the expected value is $0.939 which tells that the game is fair.

Ymorist [56]

Answer:

we are given with two terms: 20 k and 50. In this case, we are asked in the problem to factor the two terms forming the expression. The common factor of 20k and 50 is 10 because the two terms are divisible by it. The answer hence is 10*(2k +5)

A kite, flying 50 feet high in the air is attached by a string to a stake in the sand. How long is the string to the nearest ten
Vlad [161]
Height of the kite from the ground = 50 feet
Angle at which the kite is flying = 45 degrees
Let us assume the length of the string = x feet
Then
x = 50 * (square root 2)
   = 50 * 1.414
   = 70.7 feet
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the second option or option "b".
