if 1 in. = 2.54 cm, how many centimeters are in 6.11 in.?
2.54 cm
15.5 cm
0.416 cm
2.41 cm
question 5 (1 point)
how many significant figures are present in the measurement 1080 k?
1
2
3
4

Explanation:

Step1: Set up conversion for Question 4

We know 1 in = 2.54 cm. To find cm in 6.11 in, we multiply 6.11 by 2.54. So, $6.11\times2.54 = 15.5294\approx15.5$ cm (rounded to one - decimal place).

Step2: Determine significant figures for Question 5

Non - zero digits are always significant. Zeros between non - zero digits are significant. Trailing zeros in a number without a decimal point may or may not be significant. In 1080 K, the zero between 1 and 8 is significant, and the trailing zero is not significant as there is no decimal point. So, there are 3 significant figures.

Answer:

Question 4: 15.5 cm
Question 5: 3
