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!
Area of ABCE:
12 x 4
= 48cm squared
Area of CDE:
To get the height of the triangle, you subtract 4 from 10.
10 - 4 = 6cm
Base = 12 cm
12 x 6 = 72cm
72 divided by 2
= 36cm squared.
48 + 36 = 84cm squared.
(if it’s asking individual areas, then it’s 48cm and 36cm)
( a^6 b^ -3) ^ (1/3)
split them apart
( a^6) ^ (1/3) (b^ -3) ^ (1/3)
power to a power is multiply
a^ (6*1/3) b^(-3*1/3)
a^2 b^-1
a^2/b
Choice D
Answer:
just for the points
