Question

a drilling crew drills the same depth each day for 7 days. at the end of the 7 days, the crew has dug to a depth of 1344 feet. the number zero represents ground level. select the number line that represents the drilling depth relative to ground level. the change in depth each day of drilling is represented by the expression -1344÷7. the change in depth each day of drilling is represented by the value feet. the change in depth each day of drilling is because

Explanation:

Step1: Calculate daily depth change

To find the daily depth change, we divide the total depth (-1344 feet, negative because it's below ground level) by the number of days (7). So we compute $-1344 \div 7$.

Step2: Perform the division

Calculating $-1344 \div 7$, we know that $1344 \div 7 = 192$, so with the negative sign, it's $-192$. This represents the daily change in depth (since we're going down, it's negative, and dividing total depth by days gives daily depth change).

Answer:

The change in depth each day of drilling is represented by the expression $-1344\div7$. The change in depth each day of drilling is represented by the value $\boldsymbol{-192}$ feet. The change in depth each day of drilling is $\boldsymbol{-192}$ because we divide the total depth ( - 1344 feet, below ground so negative) by the number of days (7) to get the daily depth change.
