f it is solid iron, use the density to get the mass. D x V = mass
Use the mass to find the moles of Fe. Mass/atomic mass = moles
Moles x Avogadro's number will give you the particles, assuming that you mean atoms.
Answer:
32 meters
Explanation:
You use the formula a^2 + b^2 = c^2.
Plug in the length and hypotenuse.
60^2 + b^2 = 68^2
Simplify and Solve:
3600 + b^2 = 4624
4624 - 3600 = b^2
1024 = b^2
Sqrt 1024 = 32
b = 32
Answer:
Explanation:
x in (-oo:+oo)
2 < (1/2)*x-3 // - (1/2)*x-3
2-((1/2)*x)+3 < 0
(-1/2)*x+2+3 < 0
5-1/2*x < 0 // - 5
-1/2*x < -5 // : -1/2
x > -5/(-1/2)
x > 10
x in (10:+oo)
(10:+oo)
Search it up bro it’s on the internet lol
