There are 12 inches in a foot. Which expressions describe how many inches are in 4 feet? Check the THREE that apply.(3 points)Responses4 × 124 × 1212 ÷ 412 ÷ 412 + 12 + 12 + 1212 + 12 + 12 + 124 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 44 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 412 + 4

Answer 1

To find out how many inches are in 4 feet, you multiply the number of feet by the number of inches in one foot:

\[ 4 \text{ feet} \times 12 \text{ inches/foot} = 48 \text{ inches} \]

Now let's analyze the options given to find the correct expressions that result in 48 inches:

1. \(4 \times 12\) - This expression correctly computes to 48 inches (4 feet × 12 inches/foot).
2. \(12 \div 4\) - This expression results in 3, which is incorrect for finding the number of inches in 4 feet.
3. \(12 + 12 + 12 + 12\) - This adds up to 48 inches (4 instances of 12).
4. \(12 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4\) - The calculations here do not add up to 48, as it sums too high.
5. \(4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4\) - This expression is incorrect as it sums to 48 but does not use measurements in inches properly based on feet.
6. \(4 \times 12 + 12\) - This expression results in 60 (48 + 12), which is incorrect for our purpose.
7. \(12 \times 4\) - This expression correctly computes to 48 (same as option 1).
8. \(4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4\) - This calculates as 40, which is incorrect.

The correct expressions that yield 48 inches are:

1. \(4 \times 12\)
2. \(12 + 12 + 12 + 12\)
3. \(12 \times 4\)

Thus, the three expressions that describe how many inches are in 4 feet are:

• \(4 \times 12\)
• \(12 + 12 + 12 + 12\)
• \(12 \times 4\)
