Answer:

AC = 10

Step-by-step explanation:

We can apply the properties of two secants intersecting outside a circle

(see attached for reference).

in our case, our formula will be

BC (BC + AB) = CD (CD + DE), which can be written as:

BC · AC = CD · CE

We are given:

BC = 6, DC = CD = 5, CE = 12

simply substitute the known values into the equation above

6 · AC = 5 · 12

AC = (5)(12) / 6

AC = 10

The labor-force participation rate of Belgium in 2017 was 77.78%

Given:

Adult population = 4500

Number of employed in 2017 = <em>2800</em>

Number of Unemployed in 2017 = 700

Labor force participation rate = (employed + unemployed) / total population × 100

= (2800 + 700) / 4,500 × 100

= 3,500 / 4500 × 100

= 0.777777777777777 × 100

= 77.77777777777777%

Approximately, 77.78%

Given:

Adult Population in 2016 = 3500

Number of employed in 2016 = 1800

Number of Unemployed in 2016= 600

Unemployment rate = unemployed population/ total labor force × 100

= 600 / 3,500 × 100

= 0.171428571428571 × 100

= 17.14285714285714%

Approximately,

17.14 %

Therefore, the unemployment rate of Japan in 2016 was 17.14%
