Three unique samples are weighed on different scales at separate laboratories across the country. The

Question

first has a weight of 31.2 lbs, the second sample weighs 38.02 lbs, while the third measures 45 lbs. How
much is the total combined weight of all of these samples?

110 lbs

114 lbs

114.2 lbs

114.22 lbs

Answer 1

To find the total combined weight of all three samples, simply add their weights together:

1. First sample: 31.2 lbs
2. Second sample: 38.02 lbs
3. Third sample: 45 lbs

Now, calculate the total:

\[ 31.2 + 38.02 + 45 = 114.22 \text{ lbs} \]

Therefore, the total combined weight of all the samples is 114.22 lbs.
