3) The dimensions of your living room are 13 ft. by 16 ft. How many square meters of carpet
mixas84 [53]

Answer:

19.32 m²

Explanation:

The area of a living room is the product of its length and breadth. The area is given by:

Area = length × breadth

1 meter = 3.28 feet. Hence:

Length = 16 ft

16 ft = 16\ ft*\frac{1\ m}{3.28\ ft} =4.88\ m

Breadth = 13 ft

13 ft = 13\ ft*\frac{1\ m}{3.28\ ft} =3.96\ m

Area = length × breadth = 4.88 m × 3.96 m = 19.32 m²

Hence 19.32 m² of carpet is needed for the living room

Explanation:

The alimentary canal is a very long tract responsible for the digestion of the food. It is composed of several organs with many different and important functions. The alimentary canal also has a few sphincters, which are muscular valves that open and close when needed for the food to pass or be retained.

The first sphincter is the upper esophageal sphincter. One particularity of this sphincter is that is one of the few sphincters in the body that opens and closes under our conscious control, which happens when we decide to swallow our food.

From the first to the last, the order of the sphincters in the gastrointestinal tract is: upper esophageal sphincter, lower esophageal sphincter or gastroesophageal sphincter, pyloric sphincter, ileocecal sphincter, and anus.
