The tuition costs, C, for a local community college are modeled by C(h) = 250 + 200h, where h represents the number of credit hours taken. The local state university has tuition costs, s, modeled by the function S(h) = 300 + 180h How many credit hours will a student have to take for the two tuition costs to be equal? Round the answer to the nearest tenth of an hour. 1.250 + 200h = 300 + 180h 2. 250 + 200h = 300 + 180h 180h B 180h 3. 250 + 20h = 300 h = credit hours ​

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

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.

the radius is 2 times the diameter.
