Stacy needs to find the circumference of a circle with a diameter of 15 inches. She needs a pretty accurate answer, so she uses a calculator. Which answer is reasonable?
45.143672 in
47.123889 in
49.068423 in
50.714805 in

  47.123889 in

Step-by-step explanation:

The given answer choice (above) uses a value of π that is 3.1415926, which is accurate as far as it goes, but is improperly rounded in the last digit. (The next digits are ...535897932384626..., so it should be rounded to 7 in the last shown decimal place.

The properly rounded value of circumference would be 47.123890 in. The best answer choice is ...

  47.123889 in

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

step-by-step explanation:

i think you should think about the question and not look online.
