You can check your answer by substituting r = - 1 into the original linear equation.
If 4 - (-1) equals to -1 - 6 x (-1)
Then your answer should be correct.
In this case, both sides equal to 5, therefore you r correct.

A composite figure is formed from a cone and a cylinder with the same base radius, and its volume can be calculated by multiplyi

olga55 [171]

The composite figure comprises of a cone balanced on top of cylinder

Step-by-step explanation:

The composite figure is formed from a cone and a cylinder with the same base radius, Let the base radius be r

Then the volume of the cone will be $V_{cone}$

Then the volume of the cylinder will be $V_{cylinder}$

$V_{cylinder} = \pi r^{2} h_{cylinder}$

The total volume of the composite figure will be V, where

$V= V_{cone} + V_{cylinder}$

$V = \frac{1}{3} \pi r^{2} h_{cone} +\pi r^{2} h_{cylinder}$

let the height of cone and cylinder be same

The volume of the composite figure will be $\frac{4}{3} \pi r$ $r^{2} h$

Hence $\frac{4}{3} = \frac{a}{b}$

Thecomposite figure comprises of a cone balanced on top of cylinder

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%
