Answer:

Step-by-step explanation:
Given the expression 
Using law of indices: 

Also:13+8=21
Therefore:

Answer:
1 + 2sqrt(3)/3
Step-by-step explanation:
tan(30) = sqrt(3)/3
sin(90) = 1
tan(60) = sqrt(3)
cot(60) = 1/sqrt(3) = sqrt(3)/3
sqrt(3)/3 + 1 + sqrt(3)/3
1 + 2sqrt(3)/3
Multiply 8 3/4 lb by the conversion factor 16 oz
------------
1 lb
Then 35 lb 16 oz 560 oz
-------- * ----------- = ------------- = 140 oz (answer)
4 1 lb 4
I think it’s A sorry if I’m wrong
