Jose and alexia were lab partners in science class. they needed to weigh three samples of rock to the nearest thousandth. the first sample weighed 3.346 grams, the second weighed 2.479 grams, and the third weighed 9.240 grams. how much did the samples weigh altogether? 15.065 g 11.719 g 5.825 g 0.069 g

15.065 grams

Step-by-step explanation:

Given: Jose and Alexia needed to weigh three samples of rock to the nearest thousandth.The weight of the first sample = 3.346 grams

The weight of the second sample = 2.479 grams

The weight of the third sample = 9.240 grams

Add all together such that the total weight=

⇒The total weight of the samples = 15.065 grams.

Therefore, the samples weigh 15.065 grams altogether.
