The Rangers won five of the first six games. how many of the next 30 games must the rangers wins have twice as many wins as loss
barxatty [35]

Using proportions, it is found that they must win 19 of their next 30 games.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

We want a win-to-loss proportion of 2:1, which is equivalent to a win-to-total proportion of 2:3. We have that:

  • The team will have won 5 + x games.
  • The team will have played 36 games.

Hence:

\frac{5 + x}{36} = \frac{2}{3}

3(5 + x) = 72

15 + 3x = 72

3x = 57

x = 19.

The Rangers must win 19 of their next 30 games.

Kipish [7]

Answer:

$50,000

Step-by-step explanation:

250 * 10 = 2,500 units

Amount earned per unit is $20 per year

So, for 2,500 units, we have

find the least perfect square that is exactly divisible by each of the numbers 5 , 18 , 25 and 27 . ​
Dimas [21]
<h3>☂︎ Answer :- </h3>

  • 8100
<h3>☂︎ Solution :- </h3>

  • LCM of 5 , 18 , 25 and 27 = 2 × 3³ × 5²
  • 2 and 3 have odd powers . To get a perfect square, we need to make the powers of 2 and 3 even . The powers of 5 is already even .

In other words , the LCM of 5 , 18 , 25 and 27 can be made a perfect square if it is multiplied by 2 × 3 .

The least perfect square greater that the LCM ,

☞︎︎︎ 2 × 3³ × 5² × 2 × 3

☞︎︎︎ 2² × 3⁴ × 5²

☞︎︎︎ 4 × 81 × 85

☞︎︎︎ 100 × 81

☞︎︎︎ 8100

8100 is the least perfect square which is exactly divisible by each of the numbers 5 , 18 , 25 , 27 .
