the martinez family walked three over five of a mile in three over eight of an hour. what is their unit rate in miles per hour?

three-fifths over three-eights equals one and three-fifths miles per hour
three-eighths over three-fifths equals one and three-fifths miles per hour

its a straight line parallel to the time axis

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.
