your baseball team has won 6 games and lost 4 games. if the team does not lose any more games, how many games must the team win
puteri [66]

Answer:

<em></em>

<em>The team must win 2 games to have a win : loss ratio o 2.</em>

Step-by-step explanation:

  • <u>Ratio win : loss, r</u>:

       r = total wins / total losses

       

  • <u>Total wins, Tw</u>:

        Call n the number of new wins:

        Tw =number of wins until so far + number of new win = 6 + n

  • <u>Total losses, Tl</u>:

        Tl = number of losses so far + number of new losses = 4 + 0 = 4

  • <u>Target ratio</u>:

        r = 2 ⇒ Tw / Tl = (6 + n) / 4 = 2

Solve for n:

  • (6 + n ) = 4 × 2
  • 6 + n = 8
  • n = 8 - 6
  • n = 2

Hence,<em> the team must win 6 more games.</em>

  • <u>Verification</u>: (6 + 2 ) / 4 = 8 / 4 = 2, which is the target ratio.

Is it Proportional or nonproportional and and explain why
mariarad [96]

Answer:

They're both proportional because everything's moving at a constant rate. Think of it this way: If a car travels for 50 miles per hour and the speed never changes, it's proportional. If that car at hour 1 traveled at 50mph and then at hour 2 traveled at 60mph, it would be nonproportional since the speed is increasing and changing.

At a store, markers are sold in packages of 12 and pens are sold in packages of 8. What is the least amount of markers and pens
liubo4ka [24]

Given:

Markers are sold in packages of 12 and pens are sold in packages of 8.

To find:

Least amount of markers and pens Rick needs to buy to have an equal number of markers and pens

Solution:

To find the least amount of markers and pens, we need to find the LCM of 12 and 8.

Prime factors of 8 and 12 are

8=2\times 2\times 2

12=2\times 2\times 3

To find the LCM, multiply all factors but the common factors are included only once.

LCM(8,12)=2\times 2\times 2\times 3

LCM(8,12)=24

Therefore, the least amount of markers and pens Rick needs to buy to have an equal number of markers and pens is 24.
