Step-by-step explanation:

theres no answer soooo i dont think this one is right

Answer:

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

also diagonals bisect each other at right angles so 1/2×30= 15cm,, 1/2× 16 = 8cm

therefore by pythagoras theorem,

[tex] {15 }^{2} [/tex]+ [tex]{8}^{2} [/tex]= [tex] {side}^{2} [/tex][tex] \sqrt{289 = side} [/tex]

side = 17

Perimeter = 4×17 =68 cm.

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

Answer:

Step-by-step explanation:

a²+b²-c²+2ab

=a²+b²+2ab-c²

=(a+b)²-c²

=(a+b+c)(a+b-c)

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

1 = 2/5

3 1/2 = b

Multiplicar en cruz:

b = 3,5 × 0,4

b = 1,4

Por lo tanto, el kilogramo de harina requerido para hacer 3 1/2 kg de mantequilla para pasteles es 1 2/5 kg

Answer:

Answer: His estimate was low

Step-by-step explanation:

It's true that √16 is 4 and that √9 is 3

for √15 :

[tex] \sqrt{15} = 3.9[/tex]

It's true that √15 lies between 3 and 4

[tex] \sqrt{15} : 3 < x < 4[/tex]

Estimated answer :

[tex] = 3.5[/tex]

Exact answer :

[tex] = 3.9[/tex]

Therefore, the error:

[tex] \delta x = 3.9 - 3.5 \\ \\ = 0.4[/tex]

Since error is less than 0.5, his estimation was moderate, [ low ]

Answer:

Step-by-step explanation:

The change in his total score is the sum of the losses -100 + (- 75 ) +(- 85 ) = - (100 + 75 + 85 ) = - 260

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

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.

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.

Answer:

8 GB

Step-by-step explanation:

Cost = sum of fees 1, 2, and 3

C = 56 + .95g +  .08t

so

68 = 56 + .95g + .08(55)

68 = 56 + .95g + .08(55)

68 = 56 + .95g + 4.4

68 - 56 - 4.4 = .95g

7.6 = .95 g

7.6/.95 = g

8 = g

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
