Systems of equations word problem A small rental-car company has a total of 120 cars consisting of 3 types: economy, mid-size, and full-size. The daily rental fee for each is: $22 for economy, $26 for mid-size, and $31 for full-size. If there are 15 more mid-size than economy and, on a certain day, a total of $3085 is collected when all the cars are leased out, how many of each type of car does the company own?

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

42

step-by-step explanation:

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.
