Solve the following and choose the number that has the correct number of significant figures in the answer: 135.5L+13.65L=? ) 149.2 L 149.15 L 150 L 149 L

To solve the problem, we need to add the two given values and round the result to the correct number of significant figures.<br /><br />Given:<br />$135.5L + 13.65L$<br /><br />Step 1: Add the two values.<br />$135.5L + 13.65L = 149.15L$<br /><br />Step 2: Determine the number of significant figures in the answer.<br />The first value, $135.5L$, has 4 significant figures.<br />The second value, $13.65L$, has 4 significant figures.<br /><br />Since the number of significant figures in the answer should be the same as the number of significant figures in the least precise measurement, the answer should have 4 significant figures.<br /><br />Therefore, the correct answer is 149.15 L.
