Imaginá que tenés 125 dados cúbicos del mismo tamaño ¿Cuantos dados de altura tiene el cubo de mayor tamaño que podés armar apilando de manera conveniente todos ellos? Mostrá cómo lo pensaste Si quisieras formar un "cuadrado" con la mayor cantidad de cubos posibles, ¿cuántos deberías poner sobre cada lado? ¿Te quedarían cubos sueltos? ¿Cuántos? Mostrá cómo razonás

Answers

Answer:

(i) Debemos apilar 5 dados para construir el cubo de mayor tamaño.

(ii) Se necesita 121 dados cuadrados para formar el cuadrado con la mayor cantidad de dados posibles, quedando 4 dados sobrantes.

Step-by-step explanation:

(i) Sabemos por la Geometría Euclídea del Espacio que un cubo es un sólido regular con 6 caras cuadradas y longitudes iguales. Cada dado tiene un volumen de 1 dado cúbico y 125 dados dan un volumen total de 125 dados cúbicos.

El volumen de un cubo está dado por la siguiente fórmula:

[tex]V = L^{3}[/tex]

Donde:

[tex]L[/tex] - Longitud de la arista, medida en dados.

[tex]V[/tex] - Volumen del cubo, medido en dados cúbicos.

Ahora, necesitamos despejar la longitud de la arista para calcular la altura máxima posible:

[tex]L = \sqrt[3]{V}[/tex]

Dado que [tex]V = 125\,dados^{3}[/tex], encontramos que la altura del cubo de mayor tamaño sería:

[tex]L =\sqrt[3]{125\,dados^{3}}[/tex]

[tex]L = 5\,dados[/tex]

Debemos apilar 5 dados para construir el cubo de mayor tamaño.

(ii) El área cuadrada formada por cubos está determinada por la siguiente fórmula:

[tex]A = L^{2}[/tex]

Donde:

[tex]L[/tex] - Longitud de arista, medida en dados.

[tex]A[/tex] - Área, medida en dados cuadrados.

Puesto que la longitud de arista se basa en un conjunto discreto, esto es, el número de dados disponibles, debemos encontrar el valor máximo de [tex]L[/tex] tal que no supere 125 y de un área entera. Es decir:

[tex]L \leq 125\,dados[/tex]

Si cada cubo tiene un área de 1 dado cuadrado, entonces un cuadrado conformado por 125 dados tiene un área total de 125 dados cuadrados. Entonces:

[tex]L^{2}< 125\,dados^{2}[/tex]

Esto nos lleva a decir que:

[tex]L < 11.180\,dados[/tex]

Entonces, la longitud máxima del cuadrado con la mayor cantidad de cubos posible es de 11 dados. El número total requerido de cubos es el cuadrado de esa cifra, es decir:

[tex]n = (11\,dados)^{2}[/tex]

[tex]n = 121\,dados[/tex]

Se necesita 121 dados cuadrados para formar el cuadrado con la mayor cantidad de dados posibles, quedando 4 dados sobrantes.

In 1819, the United States purchased Florida from Spain for
$5 X 106. The area of Florida is about 6.6 x 104 square miles.
Which key strokes on a calculator will give the cost the
United States paid for each square mile of Florida?
A) 6.6EE4×5EE(-)6
B) 6.6EE4÷5EE6
C)5EE6×6.6EE4
D)5EE6÷6.6EE4

Answers

Answer:

D. 5 x 10⁶ ÷ 6.6 x 10⁴

Step-by-step explanation:

If 6.6 x 10^4 square miles of florida costs $5 X 10^6, then to get one square miles we will follow the given steps below;

6.6 x 10^4 mi² = $5 X 10^6

1mi² = $x

Cross multiply;

$5 X 10^6 * 1 = 6.6 x 10^4 * x

6.6 x 10⁴ x = 5 X 10⁶

Divide both sides by 6.6 x 10⁴  to get x;

6.6 x 10⁴ x /6.6 x 10⁴ = 5 x 10⁶/6.6 x 10⁴

x = 5 x 10⁶ ÷ 6.6 x 10⁴

x = 0.76*10⁶⁻⁴

x = $0.76*10²

Hence the key strokes on a calculator will give the cost the  United States paid for each square mile of Florida is 5 x 10⁶ ÷ 6.6 x 10⁴

5|2x - 3| + 4 = 9
How do you solve this

Answers

Answer:

x = 2, or x = -1

Step-by-step explanation:

If 2x - 3 is inside the parenthesis (), then the value of x is 2.

If 2x - 3 is inside the absolute value sign, then the value of x will probably be -1.

Solution 1

(10x-15) + 4 = 9

10x -11 = 9

10x = 20    -> x = 2

Solution 2 (Not 100% sure)

|10x -15| +4 = 9

10x + 15 +4 = 9

10x + 19 = 9

10x = -10      -> x = -1

−7 + 3(8n − 8) = 8(7 + 3n) please show work

Answers

Answer:

Step 1: Simplify both sides of the equation.

−7+3(8n−8)=8(7+3n)

−7+(3)(8n)+(3)(−8)=(8)(7)+(8)(3n)(Distribute)

−7+24n+−24=56+24n

(24n)+(−7+−24)=24n+56(Combine Like Terms)

24n+−31=24n+56

24n−31=24n+56

Step 2: Subtract 24n from both sides.

24n−31−24n=24n+56−24n

−31=56

Step 3: Add 31 to both sides.

−31+31=56+31

Which describes the role of oxygen in photosynthesis? A. It is a reactant, so it is released by the plant. B. It is a product, so it is released by the plant. C. It is a reactant so it enters the plant. D. It is a product, so it enters the plant. ​

Answers

Answer:

B) It is a product, so it is released by the plant.

Step-by-step explanation:

- Plants release oxygen for humans and humans give carbon dioxide to plants.

- The role of oxygen in photosynthesis is a waste product.

Answer: The oxygen gas is a product, so it is released by the plant.

Explanation:

Photosynthesis is defined as the process by which the producers make glucose with the help of carbon dioxide and water in the presence of sunlight.

The chemical equation representing this reaction follows:

In the above reaction, oxygen gas is written on the product side. So, it is formed by the plant and is released.

Hence, the oxygen gas is a product, so it is released by the plan.

What is the range & domain of the set
{(−6, 14), (10, 19), (4, -9), (3, 2), (6, −13)}

Answers

Answer:

The domain is {-6, 3, 4, 6, 10}

The range is {-13, -9, 2, 14, 19}

Step-by-step explanation:

Any set of ordered pairs has a domain and a range

The domain is the values of x-coordinates of all ordered pairs

The range is the values of y-coordinates of all ordered pairs

∵ The set is {(-6, 14), (10, 19), (4, -9), (3, 2), (6, -13)}

x-coordinates of all points are -6, 10, 4, 3, 6

→ These values are the domain of the set

∴ The domain is {-6, 3, 4, 6, 10}

y-coordinates of all points are 14, 19, -9, 2, -13

→ These values are the range of the set

The range is {-13, -9, 2, 14, 19}
