Rus_ich [418]

Answer:

31.74 million people were employed.

Step-by-step explanation:

The unemployment rate is the number of unemployed people divided by the size of the labor force.

So the first step to solve this problem is finding the size of the country's labor force.

Suppose some country had an adult population of about 46 million, a labor-force participation rate of 75 percent.

So the size of the country labor force is:

0.75 * 46 million = 34.5 million people.

Unemployment rate of 8 percent. How many people were employed?

This means that 100 - 8 = 92 percent of people were employed. Remembering, this considers only the labor force, of 34.5 million people. So

0.92 * 34.5 million = 31.74 million

31.74 million people were employed.

Answer:

250 ft.

Step-by-step explanation:

It seems that you are learning the side-splitter theorem right now. If a line is parallel to one side of the triangle and intersects the other two sides, it divides the side proportionally. From the picture we can tell that the streets are parallel, with a line of intersection. Therefore, we can create the following equation of proportionality:

$\frac{375}{300} = \frac{x}{200}$
