Answer:

x₁ = x₂ (corresponding angles are equal)

y₁ = y₂ (right angles)

z₁ = z₂

Since the angles in the first triangle are equal to the angles in the second triangle, the two triangles are similar.

Because they are similar, then the ratios of their corresponding sides are equal:

$\\\\\frac{9}{h} =\frac{11}{16}$

h = 9×16/11 = 144/11 = 13 1/11 = 13.09

Triangle ABC is a scaled copy of triangle DEF. Side AB measures 12 cm and is the longest side of ABC. Side DE measures 8 cm and

olga55 [171]

Answer: scale factor = 1.5

Step-by-step explanation:

$\text{Scale factor}=\dfrac{\text{Side length of image}}{\text{Side length of original figure}}$

Given: Triangle ABC is a scaled copy of triangle DEF.

Side AB = 12 cm and is the longest side of ABC.

Side DE = 8 cm and is the longest side of DEF.

$\text{For similar triangles, Corresponding sides are proportional.}$

AB is corresponds DE (longest side of both triangles)

So, $\text{Scale factor}=\dfrac{\text{AB}}{\text{DE}}=\dfrac{12}{8}=1.5$

Hence, the scale factor = 1.5.

Suppose the adult population of Micronesia is 100,000 people. Of these 100,000 people, 20,000 are not in the labor force. Of the

QveST [7]

Answer:

b. 6.25%

Step-by-step explanation:

In order to obtain the unemployment rate in Micronesia, you have to divide the amount unemployees that still in the labor force between the amount of people in the labor force.

The labor force is defined as the number of people employed plus the unemployed people who are seeking work.

The number of people employed is the people who work part time plus the people who are fully employed (the remainder of the 80,000 people). Therefore:

14,000 + (80,000 -16,000 - 4,000 - 14,000)

14,000+46,000=60,000

The number of unemployed people who are seeking work is:

4,000

The labor force is:

60,000 + 4,000 = 64,000

The unemployment rate is:

4,000/64,000 = 0.0625

Multiplying by 100 to obtain the percentage:

0.0625(100)=6.25%
