Answer:

5.60

Step-by-step explanation:

To find what 10 pens cost we have to go down to the cost of 1 pen first.

If 3 pens costs 1.68 then the cost of 1 pen is 1.68 divided by 3.

\frac{1.68}{3} = 0.56  

If one pen costs 0.56 then 10 pens cost 0.56 multiplied by 10.

0.56 × 10 = 5.60

There are 1,332 people under the age 20 in Pierce City. This represents 14% of the total population. What is the total populatio
MAXImum [283]

Answer:

The total population = 9514.2857143 people.

Step-by-step explanation:

Let the total population be represented by X

In the question, we are told that,1332 people are under the age of 20 and this value = 14% of the total population.

Therefore, the total population is calculated as

14% of X = 1332

14/100 × X = 1332

14X/100 = 1332

Cross Multiply

14X = 1332 × 100

X = 1332 × 100/14

X = 9514.2857143

Therefore, the total population = 9514.2857143 people.

Positive angles located in the fourth quadrant may be described as___.
gladu [14]

Answer:

Positive angles located in the fourth quadrant may be described as<u> 270≤Ф≤360 .</u>

The option is

4. 270≤Ф≤360

Step-by-step explanation:

When the terminal arm of an angle starts from the x-axis in the anticlockwise direction then the angles are always positive angles.

For Example.

Quadrant I    - 0 to 90°

Quadrant II   - 90° to 180°

Quadrant III  - 180° to 270°

Quadrant IV - 270° to 360° ( 4. 270≤Ф≤360  )

Hence,Positive angles located in the fourth quadrant may be described as<u> 270≤Ф≤360 .</u>

When the terminal arm of an angle starts from the x-axis in the clockwise direction than the angles are negative angles.

Quadrant IV  -          0° to -90°

Quadrant III   -      - 90° to -180°

Quadrant II    -      -180° to -270°

Quadrant I     -      -270° to -360°
