Ineed on which ever one you would like to do : )

a. k = n - 1     b. 15    c. 112

Step-by-step explanation:

I can answer a. b. and c. for you!

For a. let's say that the variable k means keys. And n means bits.

Since Millie can collect one less keys than there are bits, the equation is

*See top*

For b. if Antonio  has a 16-bit system, by looking at our equation we know that k = n - 1.

So, if n = 16, k = 15

For c. if each byte equals 8 bits, and there are 14 bytes, then the amount of bits would be 8 x 14.

8 x 14 = 112

where are the choices?

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
