Answer 7

then divide it by the amount of vitamin in a tablet.

Answer 8

but he said in question Express your answer as an integer.

Answer 9

You mean in decimal ?

Answer 10

Like 2.3, 5.6, 1.2 etc.

Answer 11

i dont know but he said after the question express your answer in integer

Answer 12

Answer 21

ok look about this question << While following a treasure map, you start at an old oak tree. You first walk 825 m directly south, then turn and walk 1.25 km at 30.0 ∘ west of north, and finally walk 1.00 km at 40.0 ∘ north of east, where you find the treasure: a biography of Isaac Newton!

Answer 22

part1 <<< To return to the old oak tree, in what direction should you head ? Use components to solve this problem.

Answer 23

What is your problem regarding this question ?

Answer 24

While following a treasure map, you start at an old oak tree. You first walk 825 m directly south, then turn and walk 1.25 km at 30.0 west of north, and finally walk 1.00 km at 40.0 north of east, where you find the treasure: a biography of Isaac Newton!

Answer 25

ok first convert all the identities in one mathematical system.
For example convert all the kilometers in meters.

Answer 26

What will you get ?

Answer 27

Did you do it yet ?

Answer 28
