Step-by-step explanation:

The ratios between side lenths is the same so 47.2/34.4=x/8.6 solving By cross multiplication you get 34.4x=405.92 dividing by 34.4 you get 11.8

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

unless if u could do my questions, if not i wouldn't want to
