Answer:
11.33 * 16.33 meters to the nearest hundredth.
Step-by-step explanation:
Let the width of the pool be x meters, then the length is x+5 meters.
The length of whole area = x + 5 + 2(3) = x + 11 meters and the width is
x + 2(3) = x + 6 meters.
So we have the equation (x + 6)(x + 11) = 387.
x^2 + 17x + 66 = 387
x^2 + 17x - 321 = 0
x = [-17 +/- sqrt (17^2 - 4*1*-321)] / 2
x = 11.33 meters
So the width is 11.3 m and the length is 16.33 meters.

Answer:
<h2>23.6°</h2>
Step-by-step explanation:
<h3>to understand the solving steps</h3><h3>you need to know about</h3>
- trigonometry i.g sin(x)=opp/hypo
- PEMDAS
<h3>given:</h3>
- opp:6
- hypo:15
<h3>to find:</h3>
<h3>let's solve:</h3>
therefore
<h3>xyz angle=23.6°</h3>
If i understand the question correctly the plane will fly 6 trips of 500 miles each trip.
Number of minutes it takes the plane to fly 500 miles
= 500 / 11
= 45.45 minutes
For 6 trips this = 45.45 * 6 = 272.73 minutes
= 4.55 hours to nearest hundredth.
