Question

select all the true sentences.
54.3850 > 480.4
3,405.80 ≥ 8.50
34.5 = 34.5
44.8500 < 4,540.5830

Explanation:

Step1: Analyze \( 54.3850 > 480.4 \)

Compare the two numbers. The integer part of \( 54.3850 \) is \( 54 \), and the integer part of \( 480.4 \) is \( 480 \). Since \( 54 < 480 \), \( 54.3850 > 480.4 \) is false.

Step2: Analyze \( 3,405.80 \geq 8.50 \)

The integer part of \( 3,405.80 \) is \( 3405 \), and the integer part of \( 8.50 \) is \( 8 \). Since \( 3405 > 8 \), \( 3,405.80 \geq 8.50 \) is true (because \( 3405.80 > 8.50 \), and "greater than or equal to" includes "greater than").

Step3: Analyze \( 34.5 = 34.5 \)

A number is always equal to itself, so \( 34.5 = 34.5 \) is true.

Step4: Analyze \( 44.8500 < 4,540.5830 \)

The integer part of \( 44.8500 \) is \( 44 \), and the integer part of \( 4,540.5830 \) is \( 4540 \). Since \( 44 < 4540 \), \( 44.8500 < 4,540.5830 \) is true.

Answer:

The true sentences are:
B. \( 3,405.80 \geq 8.50 \)
C. \( 34.5 = 34.5 \)
D. \( 44.8500 < 4,540.5830 \)

(Note: Here we assume the options are labeled as A for \( 54.3850 > 480.4 \), B for \( 3,405.80 \geq 8.50 \), C for \( 34.5 = 34.5 \), D for \( 44.8500 < 4,540.5830 \) based on the order in the problem. The first statement \( 54.3850 > 480.4 \) is false, so we exclude option A.)
