Area of the shaded region is 1397.46 square feet.
<h3>what is area of shaded region?</h3>
The area of the shaded region is the difference between the area of the entire polygon and the area of the unshaded part inside the polygon. The area of the shaded part can occur in two ways in polygons. The shaded region can be located at the center of a polygon or the sides of the polygon.
We are to find the area of the shaded region. For that, we will divide the figure into smaller shapes, find their areas separately and then add them up.
From the given figure, we can see that there are two semi circles or say one whole circle if we combine them at the ends while 2 rectangles at the top and bottom.
Radius of circle = 
= 17
Area of circle = 
= 
= 907.92 square ft.
Area of rectangles =2×(l×b)
= 2×20×35
= 490 square ft
Then,
Area of the shaded region = 907.92 +490
= 1397.46 square ft
Hence,Area of the shaded region is 1397.46 square ft.

Answer:
8.6023
Step-by-step explanation:
length = √[(x2-x1)^2+(y2-y1)^2]
=√[(1-6)^2+(-1--8)^2] =√74 =8.6023
Answer: x > -7
Step-by-step explanation:
so first, we move the constant to the right.
-3x < 15 + 6
the, we calculate that.
-3x < 21
then, we divide both sides.
solution: x > -7
Answer:
Se necesitan 37.5 litros del preparado que contiene 5% de jugo natural, y 12.5 litros del que contiene 25%.
Step-by-step explanation:
Primero calculamos la cantidad total de jugo natural que se necesita, a partir del volumen de jugo mixto que se quiere vender:
Ahora, que X sean los litros del preparado con jugo de 5%, y que Y sean los litros del preparado con jugo de 25%:
La suma de ambos preparados tiene que ser 50 L:
1. x + y = 50
La suma del jugo natural tiene que ser 5:
2. x*5/100 + y*25/100 = 5
Por lo que tenemos <em>un sistema de dos ecuaciones y dos incognitas</em>.
Expresamos x en términos de y:
Reemplazamos x en la segunda ecuación:
- (50-y)*5/100 + y*25/100 = 5
Y despejamos <em>y</em>:
Usando ese valor de y, calculamos x:
Answer:
0.15 years or 1.8 months
Step-by-step explanation:
I=PRT
I = interest
P = principal
R = rate
T = Time in years
Therefore,
2302.80 = 2020 × 7.6 × T
Solve for that.
T = 0.15
0.15 years = 1.8 months
