John needs to cut three strips of wood, 25.5 cm, 15.3 cm, and 9.25 cm long. he has a strip that is 72 cm long. how long will the leftover piece be after he cuts what he needs?

The leftover piece will be 21.95 cm long.

Step-by-step explanation:

Hi, to answer this we have to subtract the sum of the total length of the pieces she needs to cut (25.5 cm, 15.3 cm, and 9.25 cm) to the strip's length (72)

Mathematically speaking:

72- (25.5+15.3+9.25) = 72- 50.05= 21.95cm

The leftover piece will be 21.95 cm long.

Feel free to ask for more if needed or if you did not understand something.

step-by-step explanation:

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
