Use the situation to answer the questions. Georgette has purchased award plaques for her company's conference. Each plaque costs $7.50, and Georgette paid a one-time shipping fee of $40 for the order. Calculate total cost for the order based upon the number of plaques purchased. 9) Write the phrase that represents the constant rate of change in this situation.

i think the answer is y=7.5x +40 but if its not im really sry

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.
