Video game porsche bought a new video game. the first time she played, it took her 24 minutes to reach level 2, the second time it took 18 minutes, the third time it took 16 minutes, and the fourth time it took 12 minutes. use mental math to determine how many minutes she spent at level 1 while playing these four games.

70 minutes

Step-by-step explanation:

24+18+16+12=70

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.

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.
