Holly says 4. is a rational number. which of the following best describes if holly is correct? holly is correct. repeating decimals are always rational numbers. holly is correct. the number is positive and all positive numbers are rational. holly is incorrect. the decimal does not terminate, so it cannot be a rational number. holly is incorrect. the decimal part follows a pattern but does not actually repeat.

The correct answer is:

holly is incorrect. the decimal part follows a pattern but does not actually repeat.

Explanation:

In order to be a rational number, a decimal number must terminate or repeat.

The decimal we have is 4.131131113  This decimal does not terminate.  This means in order to be a rational number, it must repeat.

There is a pattern to the number of 3s and the number of 1s; however, the digits in this number do not repeat.  Since it is neither terminating nor repeating, this is not a rational number.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
