Hi!
If one tablet contains 10.5mg of calcium, then 20 tablets contain 20*10.5 mg = 210 mg.
1 g = 1000 mg
Knowing that : 210 mg = 0.21 grams
Hope this helps!
Answer:
the correct answer is d
Step-by-step explanation:
1st angle = X
2nd angle = X + 7
3rd angle = X + 18
Then (sum. them): 3X + 25 = 180 ==> X = 51.67 degree
Therefore,
1st angle = 51.67 degree
2nd angle = 58.67 degree
3rd angle = 69.67 degree
6 hours
12 is the answer
