find the number by which 5400 must be multiplied so that the product is a perfect cube.

Also find the cube root of the number obtained.

( Show workings )​

Answers

Answer:

Step-by-step explanation:

The easiest way (or the most reliable way) is to factor the given number into primes

5400 = 2 * 2 * 2 * 3 * 3 * 3 * 5 * 5

I cheated a little bit. 54 = 2 * 27 which is 2 * 3 * 3 * 3

100 = 2 * 2 * 5 *5

Combine the two parts and you get the factors I gave you.

Now you have to have the numbers go into groups of three. The only adjustment needed is 5 * 5 and one more 5

So the perfect cube is 5400 * 5 = 27000

Does that work? It should

27000^(1/3) = 3 * 10 = 30

So the cube root of 27000 is 30.

Trying to factor by splitting the middle term

2.1     Factoring  2y2-5y-8  

The first term is,  2y2  its coefficient is  2 .

The middle term is,  -5y  its coefficient is  -5 .

The last term, "the constant", is  -8  

Step-1 : Multiply the coefficient of the first term by the constant   2 • -8 = -16  

Step-2 : Find two factors of  -16  whose sum equals the coefficient of the middle term, which is   -5 .

     -16    +    1    =    -15  

     -8    +    2    =    -6  

     -4    +    4    =    0  

     -2    +    8    =    6  

     -1    +    16    =    15  

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

El kilogramo de harina necesario para hacer 3 1/2 kg de mantequilla para pasteles es 1 2/5 kg

1 kg de mantequilla de bizcocho = 2/5 kg de harina

Deje que la cantidad de kg de harina necesaria para hacer 3 1/2 kg de mantequilla de torta = b

Expresando Matemáticamente:

1 kg = 2/5

1 kg = 2/53 1/2 kg = b

Step-by-step explanation:

Start with the inner root:

81 + 2√1568 = 49 + 2*28√2 + 32 = 7² + 2*7*4√2 + (4√2)² = (7 + 4√2)²

Move to next one:

2 + 7 + 4√2 = 1 + 2*2√2 + 8 = 1² + 2*2√2 + (2√2)² =  (1 + 2√2)²

The last one:

2 + 1 + 2√2 = 1 + 2√2 + 2 = 1² + 2*1*√2 + (√2)² = (1 + √2)²

The root of the last one is:

You are installing a fence around your yard. In the figure,
your yard is rectangle ABCD. Each unit in the coordinate
plane represents 10 feet.
a. What is the perimeter of your entire yard
b. You consider only installing a fence around your backyard represented by rectangle ABEF what is the perimeter of your backyard?
c. The cost of fencing is $50 for each 6 foot section how much do you say by only installing a fence in the backyard?

Answers

Perimeter of a shape can be determined by the sum of its individual sides. Thus, the answers to the given questions are:

(a) 360 feet

(b) 240 feet

(c) $1000.0

Perimeter can simply be defined as the sum of all sides of a given figure or shape. Thus, the solutions required can be determined as follows:

(a) Side AB = CA = (7 - 1) x 10 feet

                            = 6 x 10 feet

                            = 60 feet

    Side AD = BC = 13 - 1

                            = 12 x 10 feet

                            = 120 feet

The perimeter of the entire yard = 60 + 120 + 60 + 120

                                                      = 360

Perimeter of the entire yard = 360 feet

(b) Side AB = EF = 60 feet

    Side FA = BE = (7 -1) x 10 feet

                                    = 60 feet

So that,

The perimeter of the backyard = 60 feet x 4

                                     = 240

Perimeter of the backyard = 240 feet

(c) The cost of installing a fence in the entire yard = [tex]\frac{360}{6}[/tex] x $50

                                     = $3000.0

 The cost of installing a fence in the back yard = [tex]\frac{240}{6}[/tex] x $50

                                    = $2000.0

The amount saved by only installing a fence in the back yard = $3000.0 - $2000.0

                                   = $1000.0

Thus, the amount saved by only installing a fence in the back yard is $1000.0

The diagonals of a rhombus are 30cm and 16cm. Find its area, the length of a side and its perimeter.​

Answers

Answer:

Area = 1/2 × product of diagonalsso area = 1/2 × 30 ×16 = 240 cm²

Write the explicit rule of the arithmetic sequence that has a first term of 3 and a fourth term of 18

Answers

Answer:

[tex]a_{n}[/tex] = 5n - 2

Step-by-step explanation:

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₄ = 18 , then

a₁ + 3d = 18 , that is

3 + 3d = 18 ( subtract 3 from both sides )

3d = 15 (divide both sides by 3 )

d = 5

Then

[tex]a_{n}[/tex] = 3 + 5(n - 1) = 3 + 5n - 5 = 5n - 2 ← explicit rule

1. A cube measures 4cm on each side and has a mass of 12 grams. What is the
density of the cube?

Answers

Answer:  0.1875 grams per cm^3

Explanation:

First we need to find the volume of the cube

volume = length*width*height = 4*4*4 = 64 cubic cm

Then we'll divide the mass over this volume to get the density

density = mass/volume

density = (12 grams)/(64 cm^3)

density = (12/64) grams per cm^3

density = 0.1875 grams per cm^3

The notation cm^3 is another way of saying "cubic centimeter" as shorthand.
