Answer:

The table does not show the proportional relationship.

Step-by-step explanation:

When y varies directly with x, then the equation is

y ∝ x

y = kx

Where 'k' is called the proportionality constant.

Given the table

x         3        6      9      12

y         12      24    45    60

Let us check from the table whether the proportionality constant 'k' remains constant or not.

FOR (3, 12)

y = kx

k = y/x

   = 12 / 3 = 4

FOR (6, 24)

k = y/x

   = 24 / 6 = 4

FOR (9, 45)

k = y/x

   = 45 / 9 = 5

FOR (12, 60)

k = y/x

   = 60 / 12 = 5

From the above calculations, it is clear that the value of 'k' does not remain constant.

This means the value of 'k' for the points (6, 24) and (9, 45) is 4, while the value of 'k' for the points (9, 45) and (12, 60) is 5.

Hence, the table does not show the proportional relationship.

7. Catalina podrá hacer un cuadrado con longitud lateral de 4 cartones

8. 45000000 = 4.5 × 10⁶

0.000000000000056 = 5.6 × 10¹⁴

0.000000000034 = 3.4 × 10¹¹

Step-by-step explanation:

6. Los valores posicionales de dígitos son;

Miles  {}     cientos       decenas      unidades

4   {}              9                5                   6

 

7. El número de cuadrados que tiene Fernando = 12

El número de cuadrados que tiene Catalina = 16

El largo y el ancho de un cuadrado son iguales, por lo tanto tenemos;

largo × ancho = Área del cuadrado

largo = ancho = lado del cuadrado

Lado del cuadrado × Lado del cuadrado = Área del cuadrado

(Lado del cuadrado) ² = Área del cuadrado

Lado del cuadrado = √ (Área del cuadrado)

Para Fernando, Área del cuadrado = 12

Lado del cuadrado para Fernando = √12 = 2 · √3 cartones

Para Catalina, Área del cuadrado = 16

Lado del cuadrado para Catalina = √16 = 4 cartones

Por tanto, Catalina podrá realizar un cuadrado con longitud lateral de 4 cartones

8. 45000000 = 4.5 × 10⁶

0.000000000000056 = 5.6 × 10¹⁴

0.000000000034 = 3.4 × 10¹¹
