Answer:

12

Step-by-step explanation:

Substitute -18 into the equation

h(-18) = 15 +(-18)/6

h(-18)= 15 + (-2)

h(-18)= 15-2

h(18)=12

12 is the final answer

\\ \sf\longmapsto h(-18)

\\ \sf\longmapsto 15+\dfrac{-18}{6}

\\ \sf\longmapsto 15+(-3)

\\ \sf\longmapsto 15-3

\\ \sf\longmapsto 12

Can someone solve this?
insens350 [35]

Answer:

<h3>            Jake is 13 years old</h3>

Step-by-step explanation:

D      - age of Dani

J = D+2    - age of Jake

E = 2J = 2(D+2) = 2D+4    - age od Ethan

Z = 2E = 2(2D+4) = 4D+8    - age of Zoe

The sum of their ages is 102:

     D  +  J  +  E  +  Z  = 102

D + D+2 + 2D+4 + 4D+8 = 102

     8D + 14 = 102

         -14          -14

      8D  =  88

      ÷8        ÷8

      D = 11

J = 11+2 = 13

6. Complete la tabla con el número 4.956: Dígito Valor posicional Notación estándar Notación en potencia De esta forma el número
Rzqust [24]

Answer:

6. Miles  {}     cientos       decenas      unidades

  4   {}              9                5               6

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
