Answer: The value of absorbance is 0.3010
Step-by-step explanation:
Transmittance,(T)= 50%
Absorbance, (A)= ?

Transmittance and absorbance are inversely related:

Hence,the value of absorbance is 0.3010 when transmittance was 50%.
Answer:
A. 55
Step-by-step explanation:
Ok, first you have to know that 0.25 is one fourth. Finding one fourth of 60 is the first step. 1/4 of 60 is 15. Now, add 3 to 15, and you have your answer! The answer is 18 pounds.
Answer:
17: 0.65
18: 0.05
19: 0.27
20: 1840
Step-by-step explanation:
That would be true because 2*4=8 and 2 goes into 8 4 times so that would be 1/4
