Step-by-step explanation:

$\to 1,728 \times {10}^{9}$

$= 1,728 \times {10}^{9}$

$= 1,728 \times 1.000.000.000$

$= 1.728.000.000$

$1,728 \times {10}^{9} = 1.728.000.000$

$\:$

$\to 4,8 \times {10}^{6}$

$= 4,8 \times {10}^{6}$

$= 4,8 \times 1.000.000$

$= 4.800.000$

$4,8 \times {10}^{6} = 4.800.000$

What are some key words used to note addition operations?

djverab [1.8K]

Answer:

The correct answer is

For addition, Caulleen used the words total, sum, altogether, and increase. But we could also have used the words combine, plus, more than, or even just the word "and". For subtraction, Caulleen used the words, fewer than, decrease, take away, and subtract. We also could have used less than, minus, and difference.

Jacob distributed a survey to his fellow students asking them how many hours they spent on the Internet in the past day. He also

Anna35 [415]

The linear equation B. y = -x +7.5 best describes the given model. The mood rating for a student that spent 5.5 hours online would be 2.

Step-by-step explanation:

Step 1; We plot the points that fall on the line and that lie on an exact x or y coordinate. The following 4 points are plotted (0.5, 7), (2, 5.5), (2.5, 5) and (3.5, 4). We substitute the values of x in the given equations to see which best describes the model.

Step 2; When y = x + 7.5, we get the coordinates as (0.5, 8), (2, 9.5), (2.5, 10) and (3.5, 11).

When y = -x + 7.5, the coordinates are (0.5, 7), (2, 5.5), (2.5, 5) and (3.5, 4).

When y = $\frac{-1x}{2}$ + 7.5, the coordinates are (0.5, 7.25), (2, 6.5), (2.5, 6.25) and (3.5, 5.75).

So equation 2 has the closest values to the actaul graph.

Step 3; By substituting x = 5.5, y = -(5.5) + 7.5 = 7.5 - 5.5 = 2.

Determine the number of ways of placing the numbers $1, 2, 3, \dots, 9$ in a circle, so that the sum of any three numbers in con

solmaris [256]

Answer:

144 ways

Step-by-step explanation:

The arrangements to have the sum of three numbers being divisible by three can be approached by modular arithmetic such that the difference between the third integer and the sum of the first two integers is divisible by 3 making them congruent modulus 3

We have;

With the first number as 1

The second number can be 2, 5 or 8

The third number can then be 3, 6, 9

The fourth number can then be 4 or 7

The sixth number can be 3, 6, 9

The seventh number can be 4 or 7

The eight number can be 2, 5, 8

and the ninth number can be 3, 6, 9

Therefore, we have

the first number as 1

The second, fifth, and eight number can be 2, 5 or 8

The third, sixth and ninth number can then be 3, 6, 9

The fourth, and seventh number can then be 4 or 7 Which gives,

The number of possible arrangements for the numbers 2, 5, and 8 = 3! = 6

The number of possible arrangements for the numbers 3, 6, and 9 = 3! = 6

The number of possible arrangements for the numbers 4, and 7 = 2! = 2

he total number of possible arrangements = 2×6×6 =72

The arrangement can be reversed in the counter clockwise directions given the total number of ways of placing the numbers 1, 2, 3,..., 9 in a circle, so that the sum of any three numbers in consecutive positions is divisible by 3 = 72 × 2 = 144 ways.
