A factory is manufactuaring cell phones that must each have a thickness of 0.5+/-0.001 inch. Which inequality describes the acceptable range of x, the thickness in inches of a cell phone?
A. 0.499 ≤ x ≤ 0.501
B. x ≤ 0.49 or x ≥ 0.51
C. x ≤ 0.499 or x ≥ 0.501
D. 0.49 ≤ x ≤ 0.51
I believe it was C
Answer: x < 39
Step-by-step explanation:
From the question, we are informed that Jordan has less than 55 minutes to finish his work and then got a phone call that lasted 16 minutes.
The inequality to show how much time he has to work will be:
x < 55 - 16
x < 39
He has less than 39 minutes
The answer is x^3. When you multiply exponents with the same base, you add the power number. Ex: x^4*x^2=x^6
