High School

1. One year the Seattle Mariners won 116 games and lost 46. What was their winning percentage? (Hint: Divide the number of games won by the total number of games played.)

2. If the body of a 155-pound person contains 93 pounds of water, what percent of his body is water?

Answer :

To solve these two questions, let's handle them one at a time.

  1. Calculating the Winning Percentage

    The formula for winning percentage is:

    [tex]\text{Winning Percentage} = \left(\frac{\text{Number of Games Won}}{\text{Total Number of Games Played}}\right) \times 100[/tex]

    In this case, the Seattle Mariners won 116 games and lost 46 games. Therefore, the total number of games played is:

    [tex]\text{Total Games} = 116 + 46 = 162[/tex]

    Now, plug the numbers into the formula:

    [tex]\text{Winning Percentage} = \left(\frac{116}{162}\right) \times 100[/tex]

    Doing the division:

    [tex]\frac{116}{162} \approx 0.716[/tex]

    And finally, multiply by 100 to convert it into a percentage:

    [tex]\text{Winning Percentage} \approx 71.6\%[/tex]

    Thus, the Seattle Mariners' winning percentage that year was approximately 71.6%.

  2. Calculating the Percent of Body Water Weight

    To find out what percent of the body weight is water, use this formula:

    [tex]\text{Percentage of Body as Water} = \left(\frac{\text{Water Weight}}{\text{Total Body Weight}}\right) \times 100[/tex]

    In this situation, we have:

  • Total Body Weight = 155 pounds
  • Water Weight = 93 pounds

Plugging in the values:

[tex]\text{Percentage of Body as Water} = \left(\frac{93}{155}\right) \times 100[/tex]

Doing the division:

[tex]\frac{93}{155} \approx 0.6[/tex]

Multiply by 100:

[tex]\text{Percentage of Body as Water} \approx 60\%[/tex]

Therefore, approximately 60% of the person's body weight is made up of water.
