Leya [2.2K]

Answer:

length of a single chain link = 5.33 cm

Step-by-step explanation:

Given data: chain contained 1000 chain links

total length was 0.0533km

<em>1km = 1000m </em>

<em> 1m = 100cm therefore 1km = 100000cm</em>

<em />

total length in cm = 0.0533* 100000

total length in cm = 5330 cm

length of a single chain link = 5330/1000

length of a single chain link = 5.33 cm

Alberto measures the length of a piece of wire to be 105 cm. The actual length of the wire was 120 cm. What was the percent erro
natali 33 [55]

Answer:

12.5%

Step-by-step explanation:

105 over 120 is the fraction that he got so you subtract 105 from 120 to get how much he missed. 120-105=15

He miscalculated by 15 cm out of the total of 120, 15/ 120

15/120=5/40=2.5/20 multiply the top and bottom by 5 to get the percentage out of 100. 2.5 times 5 =12.5, so he miscalculated by 12.5%
