Mr. Smith opened a retirement account with a deposit of $900. This account earns 5% simple interest annually. How many years will it take for his $900 deposit to earn $360 interest?

8 months=0.6 years

Step-by-step explanation:

I =PRI, where I is the interest=$360

           where P is the principal=$900, and

           where T is the time in year.

I =PRI

$360=$900*5%*T

$360=$900*5/100*T

$360=9*5*T

$360=45T

$360/45=45T/45

T=360/45

T=8 months=0.6 years

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.
