there are 46 2-digit numbers in which the tens digit is greater than the ones digit.

<h3>How many 2-digit numbers are there in which the tens digit is larger than the ones digit?</h3>

A 2-digit number is written as:

a*10 + b

Where a and b are single-digit numbers.

Tens digit and ones digit refers to place values:

a is the tens digit, and b is the ones digit. The numbers with a larger tens digit than the ones digit are:

98, 97, 96, 95, 94, 93, 92, 91, 90, 87, 86, 85, 84, 83, 82, 81, 80, 76, 75, 75, 74, 73, 72, 71, 70, 65, 64, 63, 62, 61, 60, 54, 53, 52, 51, 50, 43, 42, 41, 40, 32, 31, 30, 21, 20, 10.

We can see that there are 46 numbers in that list, so we conclude that there are 46 2-digit numbers in which the tens digit is greater than the ones digit.

kotykmax [81]

Answer:

The projected population for 2015 is around 83,600 people.

Step-by-step explanation:

If between 2005 and 2010, the population grew by 32,800 people, and the model of this problem is linear. Then that means in another 5 years, another 32,800 people would populate the area. Hopefully this makes sense!

40 divided by 6 using integer division

Nitella [24]

Answer: 40 divided by 6 is equal to 6 with a remainder of 4: 40 / 6 = 6 R.

Step-by-step explanation:Start by setting it up with the divisor 6 on the left side and the dividend 40 on the right side like this:

6 ⟌ 4 0

The divisor (6) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:

6 ⟌ 4 0

Multiply the divisor by the result in the previous step (6 x 0 = 0) and write that answer below the dividend.

6 ⟌ 4 0

Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.

6 ⟌ 4 0

- 0

Move down the 2nd digit of the dividend (0) like this:

6 ⟌ 4 0

- 0

4 0

The divisor (6) goes into the bottom number (40), 6 time(s). Therefore, put 6 on top:

0 6

6 ⟌ 4 0

- 0

4 0

Multiply the divisor by the result in the previous step (6 x 6 = 36) and write that answer at the bottom:

0 6

6 ⟌ 4 0

- 0

4 0

3 6

Subtract the result in the previous step from the number written above it. (40 - 36 = 4) and write the answer at the bottom.

0 6

6 ⟌ 4 0

- 0

4 0

- 3 6

You are done, because there are no more digits to move down from the dividend. The answer is the top number and the remainder is the bottom number. Therefore, the answer to 40 divided by 6 calculated using Long Division is: 6
