3. What is the area of the sector outlined by the dark line?
a. 150 m
b. 28.3 m
c. 11.8 m²
d. 3 m

Answers

Answer 1

Answer:

Area of sector = 11.8 m² (Approx.)

Step-by-step explanation:

Given:

Radius of a circle = 3 m

Given angle = 150°

Find:

Area of sector

Computation:

Area of sector = [θ/360][π][r]²

Area of sector = [150/360][22/7][3]²

Area of sector = [150/360][22/7][9]

Area of sector = [150/360][3.1428][9]

Area of sector = [0.4167][3.1428][9]

Area of sector = [1.345][9]

Area of sector = 11.789

Area of sector = 11.8 m² (Approx.)

Find the perimeter of this semi-circle with diameter, d = 52cm.

Answers

Answer:

Perimeter = 133.681 cm

or 52.63 inches.

Step-by-step explanation:

"So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius."

let's use,  πr + 2r

Diameter: 52

Radius: 26 (RAdius is half of the diameter)

πr + 2r (plug in)

pi x 26 + 2(26)

pi x 26 + 52

= 133.681 cm

or

= 52.63

Yes

Step-by-step explanation:

If you simplify the 1st equation,

Add like terms

3x + 9 = 12  

Subtract the 9 from both sides

3x = 3

It gives you the same equation as the other one

A set of data is normally distributed with a mean of 455 and a standard deviation of 25. What percent of the data is in the interval 405–455?
a.
47.5%
c.
68.3%
b.
49.85%
d.
34.15%

Answers

Answer:

a. 47.5%

Step-by-step explanation:

1. Find the z-score for 405: 405-455/25 = -2

2. Find the z-score for 455: 455-455/25 = 0

3. Using technology or a chart, find the percentage that corresponds with the z-scores: -2 = 0.0228 or 2.28%, AND 0 = 0.5000 or 50%

4. Find the difference between the percentages by subtracting them: 50% - 2.28% = 47.72%

5. Most of the time, the answers aren't exact, so since 47.72% is closest to 47.5%, I would say that's the answer.

What is the unit rate for the ratio 4/7: 8/21?

Answers

Answer:

The unit rate is 1.5

Step-by-step explanation:

Given

[tex]Ratio = 4/7 : 8/21[/tex]

Required

Determine the unit rate

To do this, we need to express the ratio as:

[tex]Ratio = m : 1[/tex]

Where m is the unit rate

[tex]Ratio = 4/7 : 8/21[/tex]

Express as fraction

[tex]Ratio = \frac{4/7 }{ 8/21}[/tex]

Solve

[tex]Ratio = \frac{4}{7} * \frac{21}{8}[/tex]

[tex]Ratio = 1.5[/tex]

Express as ratio

[tex]Ratio = 1.5 : 1[/tex]

Hence, the unit rate is 1.5

Answer:

c. 143.8 m³

Step-by-step explanation:

The figure can be decomposed into a semicircle and a trapezoid

Area = area of semicircle + area of trapezoid

= ½(πr²) + ½(a + b)h

Where,

r = ½(9) = 4.5 m

a = 9 m

b = 23 m

h = 7 m

Area of the figure = ½(π*4.5²) + ½(9 + 23)7

Area of the figure = 31.81 + 112

= 143.8 m³

The Empire That Vanished(1) Using archaeological studies, and Greek writings, historians now know muchmore than ever before about the mysterious group of people called the Scythians. (2)Historians have long known that they were nomadic, barbaric horsemen and a powerful force in Europe for about 400 years. (3) These people ruled a vast area of land for several centurys and then seemed to have vanished completely. (4) Artifacts found in the territory that the Scythians controlled have given clues about how they lived and what things they valued. (5) However, no evidence has been found of a centralized community, nor do historians know what eventually happened to these people. (6) Historians believe that the Scythians originally came from Asia around 700B.C., searching for better pastures and other peoples to conquer. (7) At its peak theScythian kingdom reached from the Danube river east across the Ukraine, the Crimea, and Russia. (8) Historians disagree about the size of the Scythian population. (9) Some think it numbered around half a million; other contend that it numbered only in the tens of thousands. (10) According to evidence uncovered by archaeologists, both the men and the women were feirce warriors. (11) They often traded their surplus goods and furs for crafted gold and fine ceramics made in Greece and central Asia. (12) The Scythians were especially proud of their adornments made of gold and precious stones. (13) They liked to show their wealth and even decorated their horses with gold. (14) Because of their fighting ability, the Scythians were able to acquire great riches. (15) Many of the Scythians gold ornaments found in Russia are formed into shapes that tell stories about their everyday life. (16) One elaborate gold neckpiece has figures of a resting calf, a boy milking a sheep, and bare-chested warriors with their weapons close at hand. (17) Into the image of a Scythian woman, another piece was worked, showing what the people looked like. (18) Archaeologists are still working trying to find out what happened to these people. (19) Although the Scythians left many of their treasure behind, researchers have found no trace of where these mighty warriors went.6.What is the most effective way to improvethe organization of paragraph 3 (sentences10-14)?A.
