Which one has a greater value the square root of 2 or 2.8

The way in which I interpret your question is:

Which is larger? √2 or 2.8

Note that the approx value of √2 is 1.414.

So, obviously, 2.8 is greater than√2.

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

111
