Answer:
choice A; 128.52 square feet
Step-by-step explanation:
This shape is made up of a semi-circle and a rectangle. The area of the rectangle will be 12*6 = 72 sq ft.
The formula for area of a circle is
*
. also r=radius. We are given the diameter, 12 feet. The radius is diameter/2, so the radius of the circle will be 6 feet.
Since pi is infinite we round it to 3.14.
Plug in the values and our expression will be (3.14*
)/2 because it is a semi-circle. Simplify that to (3.14*36)/2 = 113.04/2 = 56.52 sq ft.
Remember to add the area of the rectangle and semi-circle. 72 + 56.52 = 128.52 sq ft.
Answer:
Amount invested at 8% is $9000 and amount invested at 18% is $21000.
Step-by-step explanation:
Let amount invested at 8% be x.
Let amount invested at 18% be y.
We get the 1st equation as:
........(1)
We get the second equation as:

=> 
or getting rid of the decimal by multiplying by 100 on both sides.
........(2)
Multiplying (1) by 8 and subtracting from (2) we get
So, y = 21000
And 

So, x = 9000
Therefore, amount invested at 8% is $9000 and amount invested at 18% is $21000.

Responder:
14x - 40 = 310
Explicación paso a paso:
Dado que:
El baloncesto cuesta 10 € menos que un balón de fútbol
10 balones de fútbol y 4 de baloncesto cuestan 310 €
Para formar una ecuación:
Deje que el costo de:
Balón de fútbol = x
Costo del baloncesto = x - 10
Por lo tanto,
Costo de 10 balones de fútbol = 10 * x = 10x
Costo de 4 pelotas de baloncesto = 4 * (x - 10) = 4x - 40
Coste total :
Coste del balón de fútbol + coste del baloncesto = 310 €
10x + 4x - 40 = 310 €
14x - 40 = 310
14x = 310 + 40
14 veces = 350
x = 25 € = coste del balón de fútbol
Coste del baloncesto = 25 € - 10 € = 15 €
