Answer:

9/32 of the cookie was left for Stephanie to eat after lunch

Step-by-step explanation:

Anastasia’s mom baked a giant sugar cookie for her birthday.

On her birthday, ⅝ of the birthday cookie was eaten.

So, remaining cake =1 - \frac{5}{8}=\frac{3}{8}

The next day her brother ate ¼ of what remained.

Amount of cake eaten by her brother = \frac{1}{4}(\frac{3}{8})=\frac{3}{32}

So, remaining cake = \frac{3}{8}-\frac{3}{32}=\frac{12-3}{32}=\frac{9}{32}

Hence 9/32 of the cookie was left for Stephanie to eat after lunch

Si el largo de un rectángulo mide el doble del ancho que es "a", ¿cuál es su área?
rosijanka [135]

Answer:

El área es 2 veces el cuadrado del ancho del rectángulo.

Step-by-step explanation:

El área de un rectángulo viene dado por:

A = a*l

En donde:

a: es el ancho

l: es el largo

Si el largo es el doble del ancho:

l = 2a

Entonces el área es:

A = a*l = a*(2a) = 2a^{2}

Por lo tanto, el área es 2 veces el cuadrado del ancho del rectángulo.

Espero que te sea de utilidad!
