At 9: 00 a. m., bob started filling a 4,000-gallon pond. at 12: 00 p. m., he had filled 2,400. at what time will the pond be full?

2:00 P.M.

Step-by-step explanation:

Divide 2,400 by the amount of time it has taken to fill it (3). You get 800. Now subtract 2,400 from 4,000. You get 1600. 800 x 2 = 1600

Therefore add 2 hours to 12:00 to get 2:00

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.

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
