Whats the fastest way to figure out equations and inequalitys

1 answer:

4 0

Equations and inequalities are figured the same way except for that one rule with inequalities...multiplying/dividing by a negative number changes the inequality sign.
Basically, u get the variable terms on one side and everything else on the other side...then solve for the variable. The only thing that would make it faster is if u had fractions...u would turn those fractions into whole numbers by multiplying by the lowest common denominator.
Other then that, I dont know how u could make it faster.

If you stacked Avogadro's number of pennies one on top of the other on Earth's surface, how far would the stack extend (in kilom

miskamm [114]

Answer:my

The height of the stack will be 9.15×10^20_m

Or 9.15×10^17_Km

Which is 6 billion times more more than the distance to the sun

Or 22.9 million times further than the star Proxima Centauri

Step-by-step explanation:

Given

Avogadro's number = 6.02×10^23 particles

And the thickness of a penny = 1.52_mm

The height of the stack will be

1.52 × 6.02 ×10^23 = 9.15×10^23_mm 9.15×10^20_m
