A company is going to make an oil container in the shape of a cylinder. As shown below, the container will have a height of 8m and a radius of 7m. The container will be made from steel (including its top and bottom). Suppose the total cost of the steel will be $21,760.20. How much will the steel cost per square meter? Use 3.14 for π, and do not round your answer.

Answer: D

Step-by-step explanation: The amount of times a number appears is the amount of x's you put over it. D matched it.

Answer:

5. B) x = 7

6. D) 35°

7. C) 67°

8. A) 142°

Step-by-step explanation:

5. Inscribed angle of a semicircle is equal to 90°. Therefore,

16x - 22 = 90

Solve for x

16x - 22 + 22 = 90 + 22

16x = 112

16x/16 = 112/16

x = 7

6. Recall: inscribed angle = ½(intercepted arc)

3x - 1 = ½(8x - 26)

2(3x - 1) = 8x - 26

6x - 2 = 8x - 26

Collect like terms

6x - 8x = 2 - 26

-2x = -24

-2x/-2 = -24/-2

x = 12

m<LMN = 3x - 1

Plug in the value of x

m<LMN = 3(12) - 1 = 36 - 1

m<LMN = 35°

7. Recall: inscribed angle = ½(intercepted arc)

Therefore,

4x + 28 = ½(11x - 1)

2(4x + 28) = 11x - 1

8x + 56 = 11x - 1

Collect like terms

8x - 11x = -56 - 1

-3x = -57

-3x/-3 = -57/-3

x = 19

Arc BC = 360° - (Arc AC + Arc AB) (Full circle)

Substitute

Arc BC = 360 - (11x - 1 + 85)

Plug in the value of x

Arc BC = 360 - (11*19 - 1 + 85)

Arc BC = 360 - (209 - 1 + 85)

Arc BC = 360 - 293

Arc BC = 67°

8. Inscribed angles intercepted by the same arc are equal. Therefore,

8x - 41 = 5x + 1

Collect like terms

8x - 5x = 41 + 1

3x = 42

3x/3 = 42/3

x = 14

5x + 1 = ½(arc PS) => inscribed angle = ½ of intercepted arc

2(5x + 1) = arc PS

Plug in the value of x

2(5*14 + 1) = arc PS

2(70 + 1) = arc PS

2(71) = Arc PS

Arc PS = 142°

Step-by-step explanation:

The graph show that the corn stalk grown to 21 inches at week 5.

Answer:

He has to pay 15% as that is 32 and more than $25

Step-by-step explanation:

If you take 15% out of 216 it will become 32.

Answer:

10¢

Step-by-step explanation:

Step 1: Subtract 40 from 50

[tex]50 - 40 = 10[/tex]

Then, Aaron will get 10 cents back

Answer:

10 cents

Step-by-step explanation:

Answer:

See solutions below

Step-by-step explanation:

2) angle at the vertex is half that of its intercepted arc;

51 = 1/2(14x-38)

51*2 = 14x-38

102 = 14x-38

14x = 102 + 38

14x = 140

x = 140/10

x = 14

3) 9x+7 = 1/2(68)

9x + 7 = 34

9x = 34-7

9x = 27

x = 27/9

x = 3

4) 114 = 1/2(30-(8x-36+40))

114 = 1/2(360-8x+36-40)

114*2 = 356 - 8x

-8x = 228-356

-8x = -128

x = 128/8

x = 16

Answer:2

Step-by-step explanation:

51+14x-38=180

13+14x=180

14=167

X=12

Answer:

The answer is 3 out of 6 for a single die. If you're talking probability then it's a 1/3

Answer:

The other guy was right, it's 30.

Step-by-step explanation:

Think of this as 150% of 20, or 1.5 x 20.

This makes it easier to get the answer of 30.

Just a life hack I saw that made math easier :)

Have a good day!

id say the answer is ether C or A i would go with C but i might be wrong im very sorry if i am wrong

Answer:

IV. Two points: (21,430), (29,541)

29/541 - 21/430,  541-430 = 111,  29 - 21 = 8 ,

now we have 111/8 which equals 13.87, or rounded to 14the slope is 14

V. the equation is y = 14x + 94

VI. If an item has 600 calories: y = 14x + 94, substitute for y, 600 = 14x + 94, 600 - 94 = 506, 506 divided by 14 = 36.14. There are approximately 36 grams of fat in an item that has 600 calories.

VII. In my estimate, I calculated that there would be approximately 36 grams of fat in a 600 calorie item. When compared to a menu item of 600, there was only about 29 grams of fat. There are many factors that can cause such a guessed difference in between these items' grams of fat. My estimate for one was expecting a higher content of fat than what is actually advertised on this fast food menu. The fast food items that I include in my scatter plot may have all had a higher calories to fat grams ratio in general compared to this singular menu item. The location of these fast food restaurants influences the produce, meat, and other ingredients that all add to the grams of fat in the item served on the menu. 

Answer:

Yes no yes yes

Step-by-step explanation:

Answer:

60°

Step-by-step explanation:

Diameter of circle = BD ; Hence, BD = 180°

Arc BC : CD = 2 : 1

BD = BC + CD = 180

BC = 2/3 * 180 = 120°

CD = 1/3 * 180 = 60°

Since ED = 32°

BE = 180 - 32 = 148°

BA = AE

BE = BA + AE

BA = AE = 148° / 2 = 74°

Arc ABC = BA + BC

Arc ABC = 74° + 120 = 194°

P = (Arc ABC - AE) / 2

P =(194 - 74) / 2

P = 120 / 2

P = 60°

Answer:

201
