Question

Julie weighs 5 watermelons, and Ralph's weight rounds to the nearest hundredths. What is Ralph's weight in pounds?

A) 7.43 lb
B) 5.00 lb
C) 7.00 lb
D) 7.04 lb

Answer 1

Ralph's weight in pounds is D) 7.04 lb. Ralph's weight is rounded to the nearest hundredth, and in this case, it is 7.04 lb. The given information about Julie's weight and watermelons is extraneous to determining Ralph's weight. The correct answer is option D, 7.04 lb, following standard rounding rules.

Explanation:

Ralph's weight is given as 5 watermelons. Let's denote Julie's weight as J and Ralph's weight as R. According to the information provided, we have:

`\[ R = 5 * J \]`

Now, we need to determine Julie's weight to find Ralph's weight accurately. Unfortunately, the weight of Julie is not explicitly given. However, since Ralph's weight is rounded to the nearest hundredths, we can infer that the weight is likely measured with precision.

Considering option A) 7.43 lb, this implies Julie's weight ( J ) is 7.43/5 = 1.486 lb. Now, substituting this back into the equation, we find Ralph's weight:

`\[ R = 5 * 1.486 = 7.43 \]`

So, option A) 7.43 lb is the correct answer. It satisfies the condition that Ralph's weight, when rounded to the nearest hundredths, matches the given options.

In conclusion, by understanding the relationship between Julie and Ralph's weights and considering the precision of the measurement, we can determine that Ralph's weight is indeed 7.43 lb, making option A) the correct choice.
