the outside temperature at 6:00 a. m. one day was -2.3 c. the temp dropped 0.8 c each hour for the next 4 hours. what was the temp outside after the 4 hours?

4 hours × 0.8°C = 3.2°C

temperature after 4 hours

= -2.4°C - 3.2°C

= -5.6°C

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
