The answer is 6 ft 10 inches in millimeters (mm) is 0.833 ft.
Given,
The center of the school's basketball team is 6 ft 10 inches tall.
We have to convert the height of the player from feet and inches to feet.
Using the conversion factor,
1 ft = 12 inches
or, 12inches/ 1 ft
Converting 6ft 10 inches to ft, we get;
10 inches × 1 ft/ 12inches
= 0.833 ft
Therefore 6 ft 10 inches in millimeters (mm) is 0.833 ft.
Unit conversion is a method in which we multiply or divide with a particular numerical factor and then finally round off to the nearest significant digits.

Answer:
159 mg caffeine is being extracted in 60 mL dichloromethane
Explanation:
Given that:
mass of caffeine in 100 mL of water = 600 mg
Volume of the water = 100 mL
Partition co-efficient (K) = 4.6
mass of caffeine extracted = ??? (unknown)
The portion of the DCM = 60 mL
Partial co-efficient (K) = 
where; 
solubility of compound in the organic solvent and 
= solubility in aqueous water.
So; we can represent our data as:
÷ 
Since one part of the portion is A and the other part is B
A+B = 60 mL
A+B = 0.60
A= 0.60 - B
4.6=
÷ 
4.6 = 
4.6 × =
4.6 B 
= 0.6 - B
2.76 B = 0.6 - B
2.76 + B = 0.6
3.76 B = 0.6
B = 
B = 0.159 g
B = 159 mg
∴ 159 mg caffeine is being extracted from the 100 mL of water containing 600 mg of caffeine with one portion of in 60 mL dichloromethane.
The correct answer would be 3.49 times 10^ minus 24 molecules
