Answer:

6

Step-by-step explanation:

square root of 144 is 12, square root of 4 is 2, square root of 16 is 4. SO your equation is now 12x 2 divided by 4. 12 times 2 is 24. Then divide 24 by 4 and you get 6. Therfore, your answer is 6.

Answer:

a). Common difference = 4

b). [tex]T_n=4n+3[/tex]

c). 51st term = 207

Step-by-step explanation:

Given arithmetic sequence is,

7, 11, 15, 19......

a). Common difference = Second term - First term

                                      = 11 - 7

                                      = 4

b). nth term of an arithmetic sequence is given by,

   [tex]T_n=a+(n-1)d[/tex]

   Here, n = number of term

   a = First term

   d = common difference

   By substituting the values in the given formula,

   [tex]T_n=7+(n-1)4[/tex]

   [tex]T_n=4n+3[/tex]

c). 51st term of the sequence will be,

   [tex]T_{51}=7+(51-1)4[/tex]

         = 7 + 200

         = 207

Step-by-step explanation:

The improper fraction of the given mixed fraction is [tex]3\dfrac{1}{9}[/tex].

When the numerator exceeds or is equal to the denominator, the fraction is said to be inappropriate. 5/2 and 8/5, for instance, are incorrect fractions. The numerator and denominator are the two components of any fraction.

The given fraction is:

[tex]3\dfrac{1}{9}[/tex]

To convert this fraction into an improper fraction,

Multiply 3  with 9 then add it to the numerator,

[tex]\dfrac{3\times 9 + 1}{9} \\\\\dfrac{27 + 1}{9}\\\\ \dfrac{28}{9}[/tex]

Therefore,

[tex]3\dfrac{1}{9}[/tex] [tex]= \dfrac{28}{9}[/tex]

Hence,

The improper fraction of [tex]3\dfrac{1}{9}[/tex]  is [tex]\dfrac{28}{9}[/tex].

Results are below.

Step-by-step explanation:

Giving the following information:

Purchase price=  $47,000  

Salvage value= $2,900  

Useful life= 5 years

To calculate the annual depreciation, we need to use the following formula:

Annual depreciation= (original cost - salvage value)/estimated life (years)

Annual depreciation= (47,000 - 2,900) / 5= $8,820

The accumulated depreciation is calculated as follow:

Accumulated depreciation= years of depreciation*annual depreciation

For year 4:

Accumulated depreciation= 8,820*4= $35,280

Finally, the book value is:

Book value= purchase price - accumulated depreciation

Year Annual depreciation Accumulated depreciation Book value

1                 8820                                8820                  38180

2                 8820                                17640                  29360

Given:

A prism has a base area of [tex]20\pi [/tex] square units and a volume of [tex]120\pi[/tex] cubic units.

To find:

The volume of the cylinder if the cylinder has the same base area and height.

Solution:

Volume of a prism is:

[tex]V=Bh[/tex]

Where, B is the base area and h is the height of the prism.

The volume of cylinder is:

[tex]V=\pi r^2h[/tex]

[tex]V=Bh[/tex]

Where, r is the radius, h is the height of the cylinder and [tex]B=\pi r^2[/tex] is the base area.

Since base area and height of the cylinder are same as the prism, therefore, there volumes are equal.

Hence the volume of the cylinder is [tex]120\pi[/tex] cubic units.

Answer:

Triangle 2

Step-by-step explanation:

5, 12, 13

Use the Pythagorean Theorem

a^2 + b^2 = c^2

a = 5

b = 12

c = 13

25 + 144 = 169

a and b are side lengths

c is the hypotenuse

The theorem states that the square of the side lengths of a right triangle added together equals the square of the hypotenuse

Answer:

B is the right triangle because the sum of the square of each of the two shortest sides will equal the square of the longest side.

Step-by-step explanation:

Pythagorean Theorem says if a triangle is a right triangle with side lengths a, b, and c, then a^2 + b^2 = c^2 where c is the length of the longest side.

So, A. 16^2= 7^2 + 12^2  256 does not = 193 NOT a right triangle

      B. 13^2= 5^2 + 12^2  169 = 169 Yes this is a right triangle

      C. 9^2= 4^2 + 5^2  81 does not = 41 NOT a right triangle

      D. 19^2= 8^2 + 15^2  361 does not = 289 NOT a right triangle

Step-by-step explanation:

The required curved surface area =30.772 cm² and the total surface area = 1261.412 cm² for the cylinder.

The volume of a cylinder of radius 14cm is 210cm².
curved and total surface area to be determined.

The cylinder is defined as a 3D solid that keeps two identical bases joined by a curved surface, at a certain distance.

Here, Volume of cylinder(V) = 210 cm²

   V=πr2h

   h = V/πr2

   h = 210/π*14²

   h = 0.34105

Area of curved surface = 2πr*h
                                       =  2*3.14*14*0.34
                                       =  30.772 cm²

The total surface area of the cylinder,
A = 2πrh+2πr²
A = 2*π*14*0.34+2*π·*14²
A = 1261.412 cm²

Thus, The required curved surface area =30.772 cm² and the total surface area = 1261.412 cm² for the cylinder.
