A washer and dryer cost a total of $1256. The cost of the washer is three times the cost of the dryer. Find the cost of each item.

942 the washer

314 the dryer

Step-by-step explanation:

You do 1256÷4=314

Then you take 314 which is the cost of the dryer and you do 314*3=942 which is the cost of the washer

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 equation is not included but the answer is (1.50, 2.00, 2.75)
