Sati [7]

Answer:

Rate of Change = -77.9 feet/year

My interpretation: "Is Bad."

Step-by-step explanation:

The rate of change is the number of feet that Lake Powell dropped, divided by the number of years the drop took place.  We want a value with a unit of feet/year.

<u>Year</u>    <u>Feet</u>

1999     3893

2005    3425.6  

<u>Change</u>

Year = (2005 - 1999)  or 6 years

Feet = (3425.6 - 3893) or -467.4 feet

Rate of Change = (-467.4 feet)/(6 years)

Rate of Change = -77.9 feet/year

=======================

FYI:  Lake Powell is 22.39 feet lower today (June 23, 2022) than it was 1 year ago.

Reil [10]

Answer:

30 tackles between the next 2 games

Step-by-step explanation:

You can figure out how many tackles he needs for the total season by multiplying his needed average (11) by the total number of games (8+2). this gives a total of 110 tackles all season. When you add up his current tackles you will get 80 so you can tell he needs 30 more tackles to reach the desired number.
