Answer:
The high school graduating class changed by approximately 23%
Step-by-step explanation:
we have
The high school graduating class of 2010 was 260 people
Five years later the high school graduating class was 320 people.
we know that
260 people represent the 100%
so
The difference is (320-260)=60 people
using proportion
Find out what percentage represent 60 people
Let

Answer:
592 hours
Step-by-step explanation:
Given


Required
Determine the time taken to cover the area
Since, the oil formed a circular pattern; the question will be answered using area of a circle

Let t represent the time take to cover 11000m²;
The relationship between these parameters is:

Substitute 3.14 for π

Divide both sides by 3.14



Take square root of both sides



Divide both sides by 0.10




<em>(</em><em>Approximated)</em>
<em>Hence, it'll take approximately 592 hours to cover the given area</em>
