If you have a box of 250 toothpicks, what is the largest sized square you could build?

A square is made up of 4 sides, so you need to figure out the maximum number of toothpicks that can be divided into 4 piles

250/4 = 62.5, but because .5 is not a whole toothpick, you would use 4 sides of 62 tooth picks

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

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)
