PLEASE HELP!!! Douglas bikes to 7.68 miles to work 4 days of each week. (He also must bike back home.) On the other 3 days, he rides his bike along a trail that loops back to where he started and is 15.8 miles long. How many miles does Douglas bike each week?

108.84

Step-by-step explanation:

7.68*2=15.36 miles every day for work

15.36*4=61.44 miles on the 4 work days

15.8*3=47.4 miles on the other 3 days

61.44+47.4=108.84 miles a week

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 functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
