9million individuals
4 in 10 are special
how many special individuals are there

SO in 9 million people 3,600,000 are special

Step-by-step explanation:

If 4 in 10 induviduals are special that means that in 10 people, 4 are special and in 20 people 8 are special the pattern here is that to calculate the amount of special induviduals you just multiply (4/10) times that number.

SO for 9 million we get:

1696 hundred thousand

step-by-step explanation:

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
