Amalia is scuba diving at a position 24.25 feet below sea level.she descends 0.5 foot each minute for 25 minutes what is Amalias

vlada-n [284]

We can represent her initial position as -24.25, since it says she is 24.25 feet below sea level.
If she descends -.5 feet per minute, all we have to do is multiply -.5 by 25, and add it to her initial position to get the answer.
-.5*25=-12.5
-24.25+-12.5=-36.5
Her current position is -36.5
Hope this helps!

. A high school currently has a 30% dropout rate. They’ve been tasked to decrease that rate by 20%. Find the equivalent percenta

Crazy boy [7]

Answer:

The equivalent percentage point drop = 10%

Step-by-step explanation:

The percentage point change is the difference between the final and initial values.

The percentage change is the difference between the final and initial values

divided by the initial value

It is required to decrease the dropout rate from 30% to 20%

The point change = 20 - 30 = -10 (-ve change ⇒ decrease)

The percentage change = $\frac{10}{30}*100 = 33.33_%$ %

So, the equivalent percentage point drop = <u>10%</u>

And the percentage change = <u>33.33%</u>
