Ricardo has a coupon for 25% off his purchase at a craft store. Which expression could Ricardo use to calculate his total cost when purchasing x dollars of craft supplies? *

x(0.75)

If you get a 25% discount then you can subtract 25% from 100%, leaving you with 75%. If you multiply the value of x by 0.75, it will give you the final cost.

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.

ratio is 2 : 9

the answer is three

13.5 : 3
