1. how many megabytes of data can a 4.7 gigabyte dvd store?

Explanation:

Step1: Recall mass conversion factor

1 kilogram = 1000 grams.

Step2: Convert grams to kilograms

To convert 250 grams to kilograms, divide by 1000. So, $250\div1000 = 0.25$ kilograms.

Step3: Recall data - size conversion factor

1 gigabyte = 1024 megabytes.

Step4: Calculate megabytes for 4.7 gigabytes

Multiply 4.7 by 1024. So, $4.7\times1024 = 4812.8$ megabytes.

Answer:

The mass of the cart is 0.25 kilograms. A 4.7 - gigabyte DVD can store 4812.8 megabytes of data.
