Chad earns $234 for 36 hoursof work. geo earns $288 for 40 hours of work. are the pay rates of these two people proportional?

No, because 234 / 36 is 6.5 which is what Chad makes hourly. 288 / 40 is 7.2 which is what Geo makes hourly so it is not proportional.

Step-by-step explanation:

squares, rhombus, rectangles

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
