Question

Add these measurements, using significant digit rules 44.2 cm + 0.123 = ___ cm

Answer 1

Answer:

44.323 cm.

Step-by-step explanation:

We have been given two measurements. We are asked to add these measurements using significant digits.

$\text{44.2 cm}+\text{0.123 cm}$

$\text{44.323 cm}$

Now, we will use significant figures rule to give our final answer. The rules are:

• Any non-zero digits are significant. The zeros between two digits are always significant.
• Leading zeros (zeros before non-zero numbers) are not significant.
• Trailing zeros (zeros after non-zero numbers) are significant, if they are after decimal. If trialing zeros without decimal are not significant.

Since we have three non-zero digits after decimal, so these are significant digits.

Therefore, the addition of the given measurements would be 44.323 cm.
