The infinite geometric sum formula can be used to write 0.126126126...as a fraction. What is the numerator of this reduced fract

Kryger [21]

Answer:

B. 14

Step-by-step explanation:

The sum of infinite geometric series is given by

$\frac{a}{1-r}$

0.126126126... = $\frac{126}{1000}+\frac{126}{1000000}+\frac{126}{1000000000}$

Here a =126/1000, r= 1/1000

0.126126126... = $\frac{126/1000}{1-1/1000}$ =126/999 = 14/111

∴ 0.126126126... = 14/111

So, the numerator of the reduced fraction is 14.

Each small square on this scale weighs 1 unit. Each larger square weighs 10 units. The weight of the triangle x is unknown. The

Iteru [2.4K]

The equation to represent the relationship of the weights shown on the scale s $22 + x = 34$

The weights are given as:

$Small\ Square = 1$

$Larger\ Square = 10$

The total weight on one side, where there are 4 small squares and 3 large squares is:

$Total =4\times Small\ Square + 3 \times Larger\ Square$

$Total =4\times 1 + 3 \times 10$

$Total =34$

The total weight on the other side, where there are 2 small squares, 2 large squares and 1 triangle is:

$Total =2\times Small\ Square + 2 \times Larger\ Square + 1\times triangle$

$Total =2\times 1+ 2 \times 10+ 1\times triangle$

$Total =2+ 20+ 1\times triangle$

$Total =22+ 1\times triangle$

$Total =22+ triangle$

The weight of the triangle is x.

So, we have:

$Total =22+ x$

The weights on both sides are equal, because the scale is balanced.

So, we have:

$22 + x = 34$

Hence, the equation is $22 + x = 34$
