A plumber finished three jobs on tuesday. The first two only cost the owner the $45 trip fee because they took very little time to complete. For the third job, the plumber charged the trip fee plus 6 times his hourly rate. If the plumber recurved a total of $303 for the day, what is the hourly rate

$28 per hour

Step-by-step explanation:

All three jobs had a base cost of $45 which adds up to $135. The remaining amount would be six times the hourly rate. $303-$135 = $168 remaining. $168/6 = $28 per hour.

To sum it up visually in an algebraic equation,

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

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.
