Flying against the wind, a jet travels 4400mi in 8 hours. Flying with the wind, the same jet travels 5820mi in 6 hours. What is
Anna [14]
<span>distance=6390km; time=9 hrs; rate=710kph
With the wind Data:
distance=5150km; time=5hrs; rate=1030kph
EQUATIONS:

airspeed+jetstream=1030
airspeed-jetstream=710
Subtract these equations to get:
2jetstream=320kph
jetstream=160mph </span>

Find the PERIMETER of this triangle
olga2289 [7]
First we need to find the missing side, use

a =  \sqrt{ {c}^{2} -  {b}^{2}  }
So the missing leg = the sqrt of the hypotenuse squared minus the other leg squared.

Let's substitute the numbers,

a =  \sqrt{ {10}^{2}  -  {6}^{2} }
Solve for the squares,

a =  \sqrt{100 - 36}
Subtract,

a =  \sqrt{64}
Solve for the root,

a = 8
~~

So our missing length is 8.

To find the perimeter of the triangle, simply add all the sides....

~~

8 + 10 + 6 = 24

~~

Answer : 24

I hope that helps you out!!

Can someone help me find the area and perimeter for This and can you explain the process
Eva8 [605]

Answer:

<em>Area of Figure; 3.24π + 21.6 ( square meters ),</em>

<em>Perimeter of Figure; 3.6π + 12 ( meters )</em>

Step-by-step explanation:

As we can see, this picture consists of half circles and a rectangle. If we were to combine each of these half circles, we would get a whole circle with a radius of 1.8 meters;

Area of Circle; πr^2 = π * ( 1.8 )^2 = 3.24π ( square meters ),

If 1.8 is known to be the radius of this full circle, it would be that the diameter is 1.8 * 2 ⇒ 3.6. Knowing that the diameter is one dimension of a rectangle in the picture, we can assume the area of the rectangle to be;

Area of Rectangle; length * width = 6 * 3.6 = 21.6 ( square meters ),

<em>Area of Figure; 3.24π + 21.6 ( square meters )</em>

Now to determine the circumference of these two half circles / whole circle, let us apply the formula 2πr;

Perimeter of Circle; 2πr = 2π * 1.8 = 3.6π

To find the perimeter of the whole figure, we would take the lengths of two of the sides of the rectangles, in addition to the perimeter of the whole circle;

Perimeter of Whole Figure; 3.6π + 6 * 2 = 3.6π + 12 ( meters ),

<em>Perimeter of Whole Figure; 3.6π + 12 ( meters )</em>
