Use perfect squares and the number line to estimate the value of StartRoot 75 EndRoot.. A number line from 0 to 10. StartRoot 75 EndRoot. Is between 5 and 6. 6 and 7. 7 and 8. 8 and 9.

Between 8 and 9.

Step-by-step explanation:

8^2 = 64

9^2 = 81

So square root of 75 is between 8 and 9.

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
