1 mole of any substance is approximately 6.022*10^23 atoms (Avogadro's number)

So

(4.90*10^31 atoms) * (1 mole / 6.022*10^23 atoms) = 8.14*10^7 moles

Answer:

j=3 inches

Step-by-step explanation:

Since the two triangles are similar, we can set up a ratio

1in:3in

j:9in

Now we solve for j

Since the length of the side of the shorter triangle is 1/3 the length of the side of the longer triangle (as shown by the ratio 1:3 which can also be written as 1/3), we can multiply 9 by 1/3. This gives us 3.

So j=3 inches

What is the equation of the line that passes through (0, -2) and has a slope of 0? NEED HELP ASAP!!
Molodets [167]
The equation is y= -2.
How? If you recall, a linear equation is y= mx+b. The m is the slope (growth) and b is the y-intercept ( where the line crosses the y-axis).

Now since there is no slope or m, the equation would look like this:
y= b or y= 0+b

Next, you want to input the coordinator points (0, -2) into the equation. reminder: (x, y) = x=0 y= -2

y= 0+ -2
y= -2

And there you go! The equation is y= -2. I hope I help you in solving this problem, if not message me, because I'll be glad to help you.
