4 x 10^5, 9 x 10^4, 4 x 10^3, 9 x 10^3 which of these numbers is a squared number?

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

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
