muhammad, a shipping and receiving clerk uses 1 yard, 2 feet and 4 inches Of twine to wrap each carton he packs. he has to pack

antiseptic1488 [7]

Answer:

He will need 51 yards, 1 foot and 8 inches twine to wrap 29 cartons.

Step-by-step explanation:

Muhammad uses 1 yard, 2 feet and 4 inches of twine to wrap each carton he packs.

We know that, 1 yard = 36 inches and 1 foot = 12 inches.

So, 1 yard, 2 feet and 4 inches $=[(1*36)+(2*12)+4]inches = 64$ inches.

That means, he uses 64 inches of twine to wrap each carton.

He has to pack 29 cartons today. So, the total length of the twine he will need $=(64*29) inches= 1856$ inches.

Now....

1856 inches

$=\frac{1856}{36} yards \\ \\= 51 \frac{5}{9} yards \\ \\= 51 yards+(\frac{5}{9}*36)inches \\ \\= 51 yards, 20 inches \\ \\= 51 yards, (12+8)inches \\ \\=51 yards, 1 foot, 8 inches.$

Thus, he will need 51 yards, 1 foot and 8 inches twine to wrap 29 cartons.
