PLEASE HURRY I NEED HELP This Proportional situation represents (inverse, direct) variation

The constant of variation, K, is equal to (18, 162, 6, 108)

If Sergio draws a rectangle with a length of 27 centimeters, the width of the rectangle must be (4, 9, 6) centimeters

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.

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
