Answer: 4
Step-by-step explanation:
8m = 2*2*2*m
36m^3 = 2*2*3*3*m*m*m
12 = 2*2*3
GCF=2*2

Answer:
1.6x10^-18 gram
Step-by-step explanation:
(5.3 x 10⁻²³ gram/molecule) x (20,000 molecule)
= (5.3 x 10⁻²³ x 2 x 10⁴) gram
= (10.6 x 10⁻²³⁺⁴) gram
= (1.06 x 10⁻²³⁺⁵) gram
= 1.06 x 10⁻¹⁸ gram
We need to find the mass of 20,000 molecules of oxygen. It can be calculated using unitary method. Here, we can multiply 20,000 molecules by the mass of one oxygen molecule.
A. Vertical angles.
Complementary angles are adjacent angles that add to equal 90 degrees.
Adjacent angles are angles that share a side (they are right next to each other).
Supplementary angles are adjacent angles that add to equal 180 degrees.
Thus the answer is A.
Hope this helps.
