A boy scout troop is selling Christmas trees at a local tree lot. In the morning, they sold 16 Douglas Fir trees and 9 Noble Fir trees, earning a total of $977. In the afternoon, they sold 19 Douglas Fir trees and 9 Noble Fir trees, earning a total of $1,064. How much does each type of tree cost?

idk lol xd

step-by-step explanation:

ez do it yourself lazy

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.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

f(x)=2/3x-8, which give g(x) the greatest value.
