100 POINTS!!! Which statement about rational numbers is correct?

Mathematics
1 answer:
Natasha_Volkova [10]2 years ago
6 0

Answer: Rational numbers have decimal expansions that repeat or terminate.

Step-by-step explanation:

The explanation of this is the non-terminating but repeating decimal expansion means that although the decimal representation has an infinite number of digits, there is a repetitive pattern to it. The rational number whose denominator is having a factor other than 2 or 5, will not have a terminating decimal number as the result.

1. The answer is 16^2, so B.

16 x 16 = 256

2. The answer is 17, so B.

Some of the factor of 68 are: 1, 2, 4, 17, 34 and 68.

3. The answer is 15, so B.

Only 15 is composite since it contains more than a factor, which are 3 and 5. The rest of the numbers are prime since they only contain a factor.

4. The answer is 2^2^3^7, so B.

The factor tree:

84

2 x 42

2 x 2 x 21

2 x 2 x 3 x 7

Hope this helps! :)

Which are true if figure DEFG is reflected across the x-axis? Check all that apply.
meriva

Answer: The correct options are 1,2 and 3.

Explanation:

If a figure reflected across the x-axis then the x-coordinate remains same but the sign of y-coordinate changes.

According to the reflection rule across the x-axis,

(x,y)\rightarrow(x,-y)

From the given figure it is noticed that the coordinate of point D(0,4) and E(-2,0).

After reflection,

D(0,4)\rightarrow D'(0,-4)

E(-2,0)\rightarrow E'(-2,0)

Therefore the option 1 and 2 are correct.

From the given figure it is noticed the distance of point G from the x-axis is 2, therefore the distance from the G' to x-axis is also 2, because the distance of preimage and image are equal from the line of reflection.

Therefore, the option 3 is correct.

From the given figure it is noticed the distance of point D from the x-axis is 4, therefore the distance from the D' to x-axis is also 4.

Therefore, the option 4 is incorrect.

From the below figure it is clearly noticed that the orientation will not be preserved. Because the sides are not equal, so the reflection will change the orientation.
