Answer:

1. The volume of the cylinder is 263 [tex]cm^{3}[/tex].

2. The volume of the cylinder is 12 [tex]m^{3}[/tex].

3. The volume of the cylinder is 3165.1 [tex]cm^{3}[/tex].

4. The radius of the cylinder is 3.6 cm.

5a. Area of the base is 50.2 [tex]cm^{2}[/tex].

5b. The curved surface area of the pencil holder is 351.7 [tex]cm^{2}[/tex].

5c. The surface are of the pencil holder is 452.2 [tex]cm^{2}[/tex].

Step-by-step explanation:

1. The given shape is a cylinder, so that;

volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h

                                  = 3.14 x [tex](3.8)^{2}[/tex] x 5.8

                                  = 262.98128

The volume of the cylinder is 263 [tex]cm^{3}[/tex].

2. This is also a cylinder, but with a given diameter.

radius = [tex]\frac{diameter}{2}[/tex]

          = [tex]\frac{1.2}{2}[/tex] = 0.6 m

volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h

                                  = 3.14 x [tex](0.6)^{2}[/tex] x 10.6

                                  = 11.98224

The volume of the cylinder is 12 [tex]m^{3}[/tex].

3. volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h

                                      = 3.14 x [tex]6^{2}[/tex] x 28

                                      = 3165.12

The volume of the cylinder is 3165.1 [tex]cm^{3}[/tex].

4. volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h

239 = 3.14 x [tex]r^{2}[/tex] x 6

239 = 18.84 [tex]r^{2}[/tex]

[tex]r^{2}[/tex] = [tex]\frac{239}{18.84}[/tex]

   = 12.6858

r = [tex]\sqrt{12.6858}[/tex]

 = 3.5617

The radius of the cylinder is 3.6 cm.

5. Area of the base = [tex]\pi[/tex][tex]r^{2}[/tex]

radius = [tex]\frac{diameter}{2}[/tex]

           = [tex]\frac{8}{2}[/tex] = 4 cm

Area of the base = 3.14 x [tex]4^{2}[/tex]

                            = 50.24

Area of the base is 50.2 [tex]cm^{2}[/tex].

5b. Area of the curved surface of the pencil holder = 2[tex]\pi[/tex]rh

                                                                    = 2 x 3.14 x 4 x 14

                                                                     = 351.68

The curved surface area of the pencil holder is 351.7 [tex]cm^{2}[/tex].

5c. Surface area of the pencil holder = 2[tex]\pi[/tex]rh + 2[tex]\pi[/tex][tex]r^{2}[/tex]

                               = 2[tex]\pi[/tex]r(h + r)

                                = 2 x 3.14 x 4 (14 + 4)

                                = 452.16

The surface are of the pencil holder is 452.2 [tex]cm^{2}[/tex].

Answer and Step-by-step explanation:

To find the surface area, we have to find the area of all the faces of the shape, then add them together. We also only use the exposed faces, or the faces on the outside, not the inside.

Lets start with the rectangular prismed shape.

We have two faces with sides of 4 and 5, two faces with sides 16 and 4, and 1 side with 16 and 5.

Rectangles:

4 × 5 = 20

4 × 5 = 20

4 × 16 = 64

4 × 16 = 64

5 × 16 = 80

Now, let's do the triangles up top. There will essentially be 4 triangles, because we split them in half to find the area.

They have side lengths of 6 and 8.

Triangles:

6 × 8 = 48

6 × 8 = 48

6 × 8 = 48

6 × 8 = 48

Now, we have to the two rectangles up top.

They have side lengths of 10 and 4.

Top Rectangles:

10 × 4 = 40

10 × 4 = 40

Now, we add them all together.

20 + 20 + 64 + 64 + 80 + 48 + 48 + 48 + 48 + 40 + 40 =

40 + 208 + 192 + 80 =

520.

The Surface Area of the figure is 520 [tex]m^2[/tex]

Answer:

C = [tex]\frac{2.8}{7} + 0.75[/tex]

$1.15

Step-by-step explanation:

Here is the complete question :

Cookies are on sale! Today each cookie costs $0.75 less than normal price. Right now if you buy 7 of them it will only cost you $2.80!

write an equation to determine the normal price of each cookie (C). Find he normal price of each cookie.

the discounted price of one cookie = total sales price of 7 cookies / 7

$2.8 / 7 = $0.4

it was stated in the question that the sales price is  $0.75 less than normal price. Thus the normal price of the cookie = $0.4 + $0.75 = $1.15

the equation : [tex]\frac{2.8}{7} + 0.75[/tex]

Answer:

10.44'

Step-by-step explanation:

Given the box dimension :

3' * 3' * 10'

The length of the longest flagpole can be obtained using Pythagoras :

a² + b² = c²

Where, c = hypotenus = Longest side

a = 3 ` b = 10

c² = 3² + 10²

c² = 9 + 100

c² = 109

c = sqrt(109)

c = 10.44

Answer:

A. The value of n can be any positive integer resulting in the same factor

Step-by-step explanation:

Given

[tex]x^2 + 2xn + n^2[/tex] --- the right expression

[tex]n > 0[/tex]

Required

Possible values of n

[tex]x^2 + 2xn + n^2[/tex]

Expand

[tex]x^2 + 2xn + n^2 = x^2 + xn+xn + n^2[/tex]

Factorize

[tex]x^2 + 2xn + n^2 = x(x + n)+n(x + n)[/tex]

Factor out [tex]x + n[/tex]

[tex]x^2 + 2xn + n^2 = (x + n)(x + n)[/tex]

From the expression above, we can see that the result has the same factor. This means that options (b), (d) and (e) are not possible

[tex]x^2 + 2xn + n^2 = (x + n)^2[/tex]

The above also shows that n can take any positive value.

Hence: (a) is correct

Answer:

each interior angle = 150°

Step-by-step explanation:

(N x 180°) - 360° = the sum of interior angles

where N = the number of sides

(12 x 180°) - 360° = 1800°

Since it is a regular polygon, all 12 angles are equal:

1800°/12 = 150°

Answer:5

Step-by-step explanation:

Answer:

the answer is 5.

Step-by-step explanation:

_/25 = 5.

Step-by-step explanation:

So in here we can put the y-intercepts and x-intercepts together as (x, y), (x, y). (-3,0), (0,-6). And let's name them as X one, Y one and X two, Y two.

After that let's find the gradient(m) frist :

m = x-x1 / y - y1

= 0 - - 3 / -6 - 0

= 3/-6

= - 1/2

Then let's find the equation of the line :

Now we need to take one of the ys and xs we

had, (-3,0) and (0,-6). Let's take (-3,0) and the

m which is -1/2 :

y-y1 = m (x-x1)

y - 0 = -1/2 ( x - - 3)

y = -1/2 ( x +3)

y = - 1/2x - 3/2

Answer:

$ 1267.

Step-by-step explanation:

Given :

David's monthly income after tax = $ 1430.15

His health insurance cost him in a month = $ 63

Percent deducted from his income after tax for his retirement option is = 7%

Therefore money left after retirement option deduction is :

$ 1430.15 - 7% of $ 1430.15

= 1430.15 - 100.11

= $ 1330.04

= $ 1330 (aprrox)

Money deducted from this amount for his health insurance plan

= $ 1330 - $ 63

= $ 1267

Therefore, David's monthly take home pay is $ 1267.

Cyber Monday Shopping A survey of 1000 U.S. adults found that 33% of people said that they would get no work done on Cyber Monday since they would spend all day shopping online. Find the 95% confidence interval of the true proportion.

Answer:

(0.301 ; 0.359)

Step-by-step explanation:

Sample size, n = 1000

Phat = 0.33

(1 - phat) = 1 - 0.33 = 0.67

Zcritical at 95% = 1.96

Confidence interval :

Phat ± margin of error

Margin of Error = Zcritical * sqrt[(phat(1 - phat)) /n]

Margin of Error = 1.96 * sqrt[(0.33 * 0.67) / 1000]

Margin of Error = 1.96 * 0.0148694

Margin of Error = 0.0291440

Lower boundary = (0.33 - 0.0291440) = 0.300856

Upper boundary = (0.33 + 0.0291440) = 0.359144

(0.301 ; 0.359)

Answer:

Step-by-step explanation:

Answer:

the right answer will be c.360

360 degree of rotation about the origin will cause the triangle below to map onto itself.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

We have to find the degree of rotation that cause the triangle below to map onto itself.

As, A figure will be mapped onto itself if it circles the graph 360 degrees.

So, there are 360 degrees in a circle, the figure has just completed a full circle and returned to where it was before rotating.

Thus, the degree of rotation is 360.

Answer:

let the numbers be, x and x+1 ( as it is consecutive number the next number will have 1 more than the number )

sum = 41

so, x + ( x + 1 ) = 41

      x + x + 1 = 41

        2x + 1 = 41

             2x = 41 -1 = 40

              2x = 40

                x = 40/2 = 20

x = 20

x + 1 = 20 + 1 = 21

so the consecutive numbers whose sum is 40 are, 20 and 21
