Andy and sam are saving money to go on their senior trip. the amount of money that andy will have at the end of each week, w, can be expressed at a(w) = 20w + 300. the amount of money that sam will have at the end of each week, w, can be expressed at s(w) = 15w + 400. they have decided to combine their savings accounts. write a function that expresses the total amount, t(w) they have in their savings account at the end of each week.

answer: 177/8

step-by-step explanation:

27

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.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
