Bobby knows that the perimeter of the original rectangle is 120 meters. he also knows that the perimeter of the reduced rectangle is 30 meters and the reduced length is 9 meters. not drawn to scale what is the width of the original rectangle?

Width of the original rectangle is meters

Step-by-step explanation:

Perimeter of reduced rectangle meters

Reduced length meters

Reduced perimeter is equal to

The factor of reduction of perimeter of original rectangle

Width of reduced rectangle will be equal to the width of original rectangle

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)

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)
