Final answer:
The conversion of 22 inches to feet is 1.833 feet. Adding this to the initial 4 feet gives us a total of 5.833 feet. The correct answer in standard notation is 5.8 feet (option c).
Step-by-step explanation:
To convert the measurement from feet and inches to just feet, we need to first convert the inches to feet. There are 12 inches in a foot, so we divide the number of inches by 12 to convert to feet.
In this case, we have 4 feet already, and we need to add 22 inches converted into feet to this. So we calculate 22 inches ÷ 12 inches/foot = 1.833 feet. Adding this to the 4 feet we started with gives us: 4 + 1.833 = 5.833 feet.
Therefore, the correct answer is:
c) 5.8 ft.
