The base of a pyramid has n sides write an expression for the number of faces of the pyramid

The answer to the problem is n+1.

A pyramid with a rectangular base has five faces. Since pyramids can have bases with any number of sides, the formula to calculate the number of faces is the number of sides of the shape that forms the base of the pyramid plus one.

Hope this helps.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
