Answer:
I) no charge
ii) it will be positively charged
iiI) it will be negatively charged
Step-by-step explanation:
An atom is composed of electrons, neutrons and protons. Electrons are negatively charged while protons are positively charged. The number of electrons and protons in a neutral atom are exactly the same. This ensures the electrical neutrality of the atom.
However, if an atom looses an electron, there are now more protons than electrons present in the atom hence the atom is positively charged.
Similarly, if an atom gains an electron, it now contains more electrons than protons, hence it is negatively charged.
If im not mistaken the answer is D 270
500% of 120
We can set up a proprtion
120/x=100/500<span> </span>
<span>120=0.2*x </span>
<span>120/0.2=x </span>
<span>600=x </span>
<span>x=600
Final answer: 600

The answer to is 15 because your trying to make all of the angles add up to 90, which 45+30= 75 so then you only need 15 more to add up to 90.
I think
is about as simple as this is going to get. For some reason teachers like the radicals in the numerator, so we multiply top and bottom by 
and get
