What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The mixed fraction number is 1 ¹/₄.

Convert the mixed fraction number into a fraction number. Then we have

1 ¹/₄ = 1 + ¹/₄

1 ¹/₄ = (4 + 1) / 4

1 ¹/₄ = 5 / 4

Convert the fraction number into a decimal form. Then we have

5/4 = 1.25

The mixed fraction number 1 ¹/₄ into the two different forms will be 5/4 and 1.25.

A square garden has a diagonal of 12m. What is the perimeter of the garden? Express in simplest radical form.

Answers

Answer:

24√2

Step-by-step explanation:

Let the side of the square be x

If the diagonal is 12m (hypotenuse), then;

x^2 + x^2 = 12^2

2x^2 = 144

x^2 = 144/2

x^2 = 72

x = √72

x = √36*2

x = 6√2

Perimeter of the square garden = 4x

Perimeter of the square garden = 4(6√2)

Perimeter of the square garden = 24√2

Two rectangles and one triangle
Two triangles and two rectangles
no rectangles and 6 triangles​

Answers

Answer:

A. Two triangles and one rectangle.

Step-by-step explanation:

A regular hexagon has all six sides to be equal in length. The sum of its interior angle can be determined by:

                                      sum of angles = (n - 2) x 180

So that some series of different shapes can be produced from the polygon. In the given hexagon, the minimum number of shapes that can be produce is 3 which are; 2 triangles and a rectangle.

Emily is entering a bicycle race for charity. Her mother pledges $0.60 for every 0.5 mile she bikes. If Emily bikes 8 miles, how much will her mother donate?

Answers

$9.60
8miles/0.5miles= 16
$0.60 x 16 = $9.60

Answer:

Sorry this is so late but for those that need it. The answer is 4.8

Step-by-step explanation:

In order to get this i set up my equation like so.

0.60*(0.5*16)=y

Why I did it like this is because for every 0.5 thats half a mile so 8 miles times 2 to get the half miles was 16.

After figuring out that i started my equation and got

0.60*8=y

Then to finish it and get $4.8 Donated.

9. A person is sitting on a 30 foot pier overlooking the ocean. His eye level is 3 feet above the

pier. He sees a whole surface in the ocean. If the angle of depression of the whale is 20", how

far is the whale from his eyes?

Answers

Answer:

90.67feet

Step-by-step explanation:

Given that α = 20°

Tan α = opp/adj......... 1

Opp = 33feet

Adj = x

Substitute the values into equation 1

Tan 20° = 33feet/adj

0.36397 = 33/adj

0.36397×adj = 33

Adj = 33/0.36397

Adj = 90.666

Recall, adj = x = 90.666feet

x = 90.67feet

Hence, the whale is 90.67feet far from the eyes

Sea un cuadrado de 2 pulgadas de lado uniendo los puntos medios se obtiene otro cuadrado inscrito en el anterior si repetimos este proceso obtenemos una progresión de infinitos cuadrado comprobar que la área de los infinitos cuadrados forman una progresión geométrica y calcula la suma de todas las áreas

Answers

Answer:

1) La serie geométrica formada es

4, 2, 1,..., ∞

2) La suma al infinito de las áreas de los cuadrados es 8 in.²

Step-by-step explanation:

1) El área del primer cuadrado, a₁ = 2² = 4 pulgadas²

El área del siguiente cuadrado, a₂ = (√ (1² + 1²)) ² = (√2) ² = 2 pulg²

El área del siguiente cuadrado, a₃ = ((√ (2) / 2) ² + (√ (2) / 2) ²) = 1 pulg²

Por lo tanto, la razón común, r = a₂ / a₁ = 2/4 = a₃ / a₂ = 1/2

Las áreas de los cuadrados progresivos forman una progresión geométrica como sigue;

4, 4×(1/2), 4 ×(1/2)²,...,4×[tex](1/2)^{\infty}[/tex]

De donde obtenemos la serie geométrica formada de la siguiente manera;

4, 2, 1,..., ∞

2) La suma de 'n' términos de una progresión geométrica hasta el infinito para -1 <r <1 se da como sigue;

[tex]S_{\infty} = \dfrac{a}{1 - r}[/tex]

Por lo tanto, la suma de las áreas de los cuadrados hasta el infinito se obtiene sustituyendo los valores de 'a' y 'r' en la ecuación anterior de la siguiente manera;

[tex]La \ suma \ al \ infinito \ del \ cuadrado \ S_{\infty} = \dfrac{4 \ in.^2}{1 - \dfrac{1}{2} } = \dfrac{4 \ in.^2}{\left(\dfrac{1}{2} \right)} = 2 \times 4 \ in.^2= 8 \ in.^2[/tex]

La suma al infinito de las áreas de los cuadrados, [tex]S_{\infty}[/tex] = 8 in.²
