4 hours ago = 1,000

2 hours ago = 2,000

Now = 4,000

In 2 hours = 8,000

In 4 hours = 16,000

In 6 hours = 32,000

In 8 hours = 64,000

In 10 hours = 128,000

In 12 hours = 256,000

The answer would be D. 12 hours.

Is (3,6) a solution of y's 3x + 4?
notka56 [123]

Step 1:

(3,6) means x coordinate is 3 and y coordinate 6

Step 2:

We substitute the values of x = 3 and y = 6 into the inequality

\begin{gathered} y\text{ }\leq\text{ }\frac{2}{3}\text{ }x\text{ + 4} \\ 6\text{ }\leq\text{ }\frac{2}{3}\text{ x }\frac{3}{1}\text{  + 4} \\ 6\text{ }\leq\text{ 2 + 4} \\ 6\text{ }\leq\text{ 6} \end{gathered}

Conclusion:

Since 6 is equal to 6, then (3,6) is a solution of the given Inequality

Why do plasma particles have charges?​
r-ruslan [8.4K]

Answer:

"Because the particles (electrons and ions) in a plasma have an electrical charge, the motions and behaviors of plasmas are affected by electrical and magnetic fields. ... Ions have a positive electrical charge because they have more positively charged protons than negatively charged electrons."

The reason i say this is because i don't really want to run into something that i don't know much about. I do know quite a bit about extinct animals more than i do aliens. So, that's my reasoning.
