To function properly, a rainwater outflow pipe must drop exactly 1 inch for every 25 inches of horizontal distance. a design calls for a drainage pipe to drop 25 inches as it crosses a building 45 feet wide. will the drainage pipe function properly? a. the pipe does not drop enough vertically to function properly. b.the pipe drops too much vertically to function properly. c.the pipe will function properly. d.there is not enough information to determine if the pipe will function properly

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

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.
