Three friends pay $1,025 to rent a vacation home. beth contributed $80 more than danny. katie contributed $20 less than beth. how much did danny contribute?

  $295

Step-by-step explanation:

Let d represent the amount Danny contributed. Then Beth contributed (d+80) and Katie contributed ((d+80)-20) = (d+60). The total from the three friends is ...

  d + (d+80) +(d+60) = $1025

  3d = 885 . . . . . . . . . . . . . . . . . . . subtract 140

  d = 295 . . . . . . . . . . . . . . . . . . . . divide by 3; Danny's contribution

Danny contributed $295.

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.
