The ideal length of a particular metal rod is 20.5 cm. The measured length may vary from the ideal length by at most 0.045 cm. What is the range of
acceptable lengths for the rod?
O A. X5 20.455 or x 2 20.545
B. 20.455 > x < 20.545
O C. 20.455 2 x 2 20.545
D. 20.455 < x < 20.545

D

Step-by-step explanation:

given that the ideal length x = 20.5cm

range = ± 0.045

hence the lower limit will be (20.5 - 0.045) and the upper range will be (20.5 + 0.045), i,e

(20.5 - 0.045) < x < (20.5 + 0.045)

or

20.455 < x < 20.545  (answer D)

146 days

step-by-step explanation:

1. (365*2)/5 =

730/5 =
