Question

1. in 2009, mrs. sullivan discovered that children ages 6 - 11 years old spend sixty - nine thousand, one hundred eight minutes a year watching television. what is this number written in standard form?

a. 6,918
b. 69,108
c. 69,180
d. 690,108

Explanation:

Step1: Analizar la descripción numérica

La frase dice "sixty - nine thousand, one hundred eight". Entonces, se descompone el número: 69 mil (69,000) + 100 + 8.

Step2: Calcular el valor numérico

Calculamos \(69000 + 100+8\). Primero, \(69000 + 100 = 69100\), luego \(69100+8 = 69108\)? Espera, no, la opción b es 69,108? Wait, la descripción es "sixty - nine thousand, one hundred eight". Entonces:

• 69 mil es \(69\times1000 = 69000\)
• 100 es \(1\times100 = 100\)
• 8 es \(8\times1 = 8\)

Sumando: \(69000+100 + 8=69108\)? Wait, no, la opción b es 69,108? Wait, la pregunta dice "sixty - nine thousand, one hundred eight". Entonces:
Si es "sixty - nine thousand, one hundred eight", entonces:
69,000 (sixty - nine thousand) + 100 (one hundred) + 8 (eight) = 69,108. Entonces la opción correcta es b.

Answer:

b. 69,108
