Sixty-five percent of the 8th grade class is selling magazines for the class fundraiser. If 195 students are selling magazines, how many students are in the whole 8th grade class?

300 students

Step-by-step explanation:

If 195 students is 65%, then we can divide 195 by 65 to find what 1% is.

195/65= 3

So 1% of the 8th grade class is 3 students. We want to know how many students are in the whole class, which would be 100% of the class.

If we multiply the 3 (which is 1%) by 100 (to get 100%) we can find the total number of students.

3x100=300

We can check this by finding 65% of 300, and seeing if that is 195.

300x.65=195

It does check out.

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.

15.36 per mile

but forgot to round

i am pretty sure
