If 9 out of 25 people are left-handed what percent are right-handed

64%

Step-by-step explanation:

If  9 out of 25 people are left-handed

That means 25-9 = 16 people are right handed

or 16/25 are right handed

Multiply the top and bottom by 4 to get it out of 100

64/100

Percent means out of 100

64% are right handed

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
