Akimi4 [234]

The digit in the hundreds place has a value 10 times as great as the value in the tens place. The digit in the tens place has 1/10 the value of the digit in the hundred place

<h3>What is place value?</h3>

Place value is simply the value of each digit in a number.

For instance:

  • The 3 in 350 represents 3 hundreds, or 300
  • The 5 in 5,006 represents 5 thousands, or 5,000.

It is important to note that place value is the value represented by a digit in a number on the basis of its position in the number or figure.

We can deduce the following:

  • The digit in the hundreds place has a value 10 times as great as the value in the tens place
  • The place value of a digit at the hundredths place is 1/10 times the same digit at the tenths place

Thus, the digit in the hundreds place has a value 10 times as great as the value in the tens place. The digit in the tens place has 1/10 the value of the digit in the hundred place

How could you use coordinate geometry to prove that segment BD and segment AC bisect one another?
____ [38]

Answer:

I think it's prove the midpoints are the same

Step-by-step explanation:

I'm not completely sure but I'm taking it right now and I believe that's the most logical answer because if they meet up at the same midpoint then they could bisect each other.
