Rita is planting saplings along her garden fence. when she started, she had x packages of saplings with 5 saplings per package. she planted 15 saplings and has at most 20 left. how many packages of saplings did she start with? what would the solution look like on a number line graph? when rita started, she had x packages of saplings. the solution can be represented as c with an arrow to the y .

5·x - 15 ≥ 0 --> x ≥ 3

5·x - 15 ≤ 20 --> x ≤ 7

395.84

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

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.
