Use the law of sines to find the value of w.

Lunna [17]

Option B: 4.0 cm is the value of w

Explanation:

It is given that $\angle W= 39$ , $\angle U=31$ , $VW=3.3$ and $UV=w$

Using the law of sines, we have,

$\frac{sin U}{3.3} =\frac{sin W}{w}$

Substituting the values, we have,

$\frac{\sin 31}{3.3}=\frac{\sin 39}{w}$

Cross multiplying, we get,

$(sin31) w=3.3( \sin 39)$

Simplifying, we have,

$0.515w=2.077$

Dividing both sides by 0.515, we have,

$w=4.0$

Thus, the value of w is 4.0 cm

Hence, Option B is the correct answer.

A factory makes 7000 flash drives each week. For testing purposes,

Anika [276]

Answer:

245 flash drives

Step-by-step explanation:

We can assume that the proportion of broken flash drives in the 200 drive sample is the same as the proportion of broken flash drives in the weekly output. Therefore, if we let $x$ be the number of broken flash drives produced that week, we can write the following equation:

$\frac{7}{200} =\frac{x}{7000}$

Solving for $x$ , we get:

$\frac{7}{200} =\frac{x}{7000}$

$7000 * \frac{7}{200} =x$ (Multiply both sides of the equation by $7000$ to isolate $x$ )

$\bf x=245$ flash drives (Multiply)

Hope this helps!
