12men or 18women can reap a field in 14 day ,8man and 16women can reap the same field in​

Step-by-step explanation:

12 men and 18 women: x1; 14 days; y1

8 men and 16 women: x2; ?; y2

12/18 simplified is equal to 2/3

8/16 simplified is equal to 1/2

This is a direct proportion, thus we can say that:

(1/2*14)/(2/3)=y2

7/(2/3)=10.5 days

I hope this helped you get out of homework trouble :D

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.
