Explain why any rational number is either a terminating or repeating decimal?

Mathematics
1 answer:
harkovskaia [24]3 years ago
6 0
Because if the number was rational then we can tell by looking at the numbers. The rational number should be one number or a repeating decimal or terminating number. plus because if a number was like this 5.7696... that means its irrational because we dont know the end of the number. The rational numbers are terminating numbers or either decimal or repeating numbers because we know the end of those numbers.

yesterday, 2000 circular jellyfish, each of diameter 2 feet, were lying within a section of ocean floor that measured 120' by 36
Ymorist [56]
The area of one jellyfish is pi r squared or 3.14 x 1 squared (the diameter of the jellyfish is 2 feet so the radius is 1 foot) or essentially 3.14 square feet. 2000 x 3.14 = 6280 square feet. The area of the ocean floor is 120 x 360 feet or 43200 square feet. So 6280/43200 is equal to 0.15 or 15%

What is the answer to x^2-11=25 please
Westkost [7]

Hey there!

\mathsf{x^2 - 11 = 25}

\large\textsf{ADD 11 to BOTH SIDES}

\mathsf{x^2 - 11 + 11 = 25 + 11}

\large\textsf{CANCEL out: -11 + 11 because that gives you 0}

\large\textsf{KEEP: 25 + 11 because that helps solve for the x-value}

\mathsf{25 + 11 = \bf 36}

\large\textsf{NEW EQUATION: }\mathsf{x^2=36}

\large\textsf{Take the square root of the number (36)}

\mathsf{x = \pm \sqrt{36}}

\mathsf{\pm = \boxed{\bf plus-or-minus}}

\mathsf{x = \sqrt{-36}\rightarrow \bf -6}

\large\textsf{or}

\mathsf{x = \sqrt{36} = \bf 6}

\boxed{\boxed{\huge\textsf{Answer: \bf x = 6 or x = -6}}}\huge\checkmark

\large\text{Good luck on your assignment and enjoy your day!}
