In the measurement 0.503 l, which digit is the estimated digit? the 0 immediately to the left of the 3 5 the 0 to the left of the decimal point 3

3.

Step-by-step explanation:

We are asked to find the estimated digit in the measurement 0.503 L.

We know that in each measurement the estimated digit is always the last digit.

We can see that the first digit in the given measurement is 5, the second digit is 0 and the last digit is 3.

Since the last digit is in our given measurement 3, therefore, the estimated digit is 3.

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
