Answer:
1. 8.3%
Step-by-step explanation:
Relative error = absolute error/expected measurement
The expected measurement is given as 6 ft.
Now, the absolute error is usually equal to half of a unit of the measure.
This means the absolute error in this case is ½ × 1 = 0.5 ft
Thus, the exact measurement will be;
6 ± 0.5
Thus;
Relative error = 0.5/6
Relative error = 0.083
Expressing it in percentage gives 8.3%

Answer:

Step-by-step explanation:




1 3 /10. That’s the answer because you have to carry over the six bc 2/10 is less then 9/10
7/10... 14/20, 28/40
12/11... 6/6.5, 24/22
3/2... 6/4, 12/8
11/4... 22/8, 33/16
5/12... 10/24, 20/48
