The length of a shadow of a building is 27 m. The distance from the top of the building to the tip of the shadow is 31 m. Find the height of the building. If necessary, round your answer to the nearest tenth.

its like a triangle

shadow is the base

31 meters is the hypotenuse

a^2 + b^2 = c^2

27^2 + b^2 = 31^2

b = square root of 232 which is 15.2315462117

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

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.
