Which of the following is a true statement?

1. all square roots are irrational.
2. all decimals are irrational.
3. all non-perfect squares have irrational square roots.
4. all irrational numbers can be written as ratios of two integers

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
