Thanks CPhill, that is a good answer also.   

if a book has a mass of 2.2 what is its weight on earth

2.2 what?

2.2 tons perhaps ?  or was thast 2.2 jellybeans?

anyway I will assmume that the mass is 2.2 kg

F=mass * accel   (=weight)

Weight = 2.2*9.8 Newtons        

Sorry Okim2001, I was off doing something else :)

Well post your question then. :)

this is how :)

89z – 66z – -71z – -85 = -9

89z – 66z +71z +85 = -9

89z – 66z +71z      +85-85 = -9-85

(89 – 66  +71 )z      = -94

89-66+71 = 94

94z = -94

divide both sides by  94

z= -1

It depends what you mean

\(\sqrt4*(ab^4*c) = 2ab^4c\\ or\\ \sqrt[4]{ab^4*c\;}=b\sqrt[4]{ac\;}\)

No, purple is a descriptive work.  It is an adjective.

Verbs are doing words, like 'jump' because you can jump.

Inverse tan is the same as arc tan
