1) By rounding each number to 1 significant figure, estimate the answers to

23.4*13.9

0.18

2) work out an estimate for

√4.92+2.18*7.31

3) using approximations to 1 significant figure, estimate the value of

0.482*61.2^2

√98.01

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
