Please answer this question

Zina [86]

Answer:

$y = 9.1$

Step-by-step explanation:

Use the Law of sines to find y in ∆WXY, given:

m < Y = 106°

m < X = 58°

WY = x = 8

WX = y = ?

Therefore,

$\frac{y}{sin(Y)} = \frac{x}{sin(X)}$

$\frac{y}{sin(106)} = \frac{8}{sin(58)}$

$\frac{y}{0.961} = \frac{8}{0.848}$

$\frac{y}{0.961} = 9.434$

Multiply both sides by 0.961 to solve for y

$\frac{y*0.961}{0.961} = 9.434*0.961$

$y = 9.434*0.961$

$y = 9.1$ (to nearest tenth)

Which fraction is equivalent to StartFraction 2 Over 6 EndFraction? StartFraction 3 Over 7 EndFraction, because StartFraction 2

irinina [24]

Question:

Which fraction is equivalent to $\frac{2}{6}$ ?

- $\frac{3}{7}$ because $\frac{2}{6}= \frac{2 + 1}{6 + 1}$

- $\frac{3}{9}$ because $\frac{2}{6}= \frac{1}{3}$ and $\frac{1}{3} = \frac{3}{9}$

- $\frac{3}{12}$ because $\frac{2}{6}= \frac{1}{3}$ and $\frac{1}{3} = \frac{3}{9}$

- $\frac{3}{8}$ because $\frac{2}{6}= \frac{1}{2} = \frac{2+1}{6+2} = \frac{3}{8}$

Answer:

- $\frac{3}{9}$ because $\frac{2}{6}= \frac{1}{3}$ and $\frac{1}{3} = \frac{3}{9}$

Step-by-step explanation:

Two fractions are said to be equal if and only if they give the same value when simplified.

The equivalent of $\frac{2}{6}$ is as explained in the selected option;

First, divide numerator and denominator by 2

$\frac{2/2}{6/2}$

Then simplify

2/2 = 1 and 6/2 = 3; So;

$\frac{2/2}{6/2} = \frac{1}{3}$

Multiply numerator and denominator by 3

$\frac{1*3}{3*3} = \frac{3}{9}$

Hence, $\frac{2}{6}$ is equivalent to $\frac{3}{9}$
