Answer:

he total time is 4 seconds. The elevator descends 10 feet each second so the total is:

 

4seconds x -10 feet/sec = -40 feet

 

The total change in elevation is -40 feet. You need the negative sign because the elevator is moving downward. Hope this helps!

tekilochka [14]
Lets calculate how much she walks each weeks and then we multiply that by the number of weeks.
weekWalk = 5(2) + 3 = 10 + 3 = 13
therefore, she walks 13 miles per week, if she walked for 29 weeks then we have:
total walked =(29)(13) = 377
so she walked 377 miles total, so her original estimate is not reasonable

Factor −1/3 out of −1/3x−8.
Gnom [1K]

For this case we have the following expression:

- \frac {1} {3} x-8

We take common factor - \frac {1} {3}, for this we must take into account that:

- * + = -\\\frac {24} {3} = 8

So, factoring the expression we have:

- \frac {1} {3} (x + 24)

ANswer:

The factored expression is:

- \frac {1} {3} (x + 24)
