A 54-inch board is cut into two pieces. One piece is two times the length of the other. Find the length
of the shorter piece.

The shorter piece is how many inches long?

18

Step-by-step explanation:

if the board was cut by 2, and one is 2 times the size of the other

54/3= 18

if one side is 18 (the short side)

and the long side is 36 (18x2=36)

36+18= 54

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
