Find and plot √2.
1. approximate between two whole numbers.
12 = 1, 22 = 4
2. approximate further by squaring the number halfway between 1 and 2.
1.52 = 2.25
3. plot the square root on the number line.
the square root lies between

and 1.5 on the number line.

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
