Answer:

Mario perdió dinero, perdió 2500 dólares

Step-by-step explanation:

En el primer caso, Mario está vendiendo su carro en 30 000 dólares. En otras palabras, el precio de venta es 30 000. Te dice que en el primer carro ganó 20%, o sea que su precio de venta es una incógnita que llamaremos x y gano 20% de x. Podemos expresarlo de esta manera

x = precio de compra carro 1

x + (20% de x) = 30 000

x = 100 % de x

(100% de x) + (20% de x) = 30 000

120% de x =30 000

120% = 1.2

1.2x = 30 000

x = 25 000

El segundo caso es bastante parecido. Te indica que el precio de venta sigue siendo el mismo, pero el precio de compra es diferente. El precio de venta sigue siendo 30 000, pero el precio de compra del segundo carro esta vez será "y". En este caso, pierde 20% del precio de compra, o osea, pierde 20% de y. Se puede expresar de la siguiente manera:

y = precio de compra carro 2

y - (20% de y) = 30 000

y = 100% de y

(100% de y) - (20% de y) = 30 000

80% de y = 30 000

80% = 0.8

0.8y = 30 000

y= 37 500

Entonces tenemos que el precio de compra del carro uno es 25 000 dólares y el precio de compra del carro dos es de 37 500. Si sumamos ambas cantidades, tenemos que ambos carros costaron 62 500 dólares. Como vendió esos dos autos a 30 000 dólares cada uno, recibió 60 000 dólares. El precio por el que vendió los autos (60 000) es menor al precio del que los compro (62 500), por lo que eso representa una perdida.

Para hallar la cantidad que ganó o perdió (en este caso perdió) debes restar el precio de venta menos el precio de compra.

60 000 - 62 500 = -2 500

Como es un número negativo, representa una perdida.

Answer:

8.94

Step-by-step explanation:

Given that

qs = 12cm

qr = 8cm

Required  

rs

Using the pythagoras theorem

Let us assume qs is the hypotenuse side

qs² = qr² + rs²

12² = 8² + rs²

144 = 64 +rs²

rs² = 144 - 64

rs² = 80

rs = √80

rs = 8.94

Hence the value of rs is 8.94

Answer:

10 ft-lbs.

Step-by-step explanation:

Given data

Weight of box=  5 lb

Height moved = 2 feet

We know that the expression for work done is

Work done= Force * Distance

Work done= 5*2

Work done= 10 10 ft-lbs.

Answer:

y = 0 is the midline equation.

Step-by-step explanation:

The midline equation of y = 2 sin( pi/2 x+3) is the same as that of

                                         y = 2 sin( pi/2 x+3) or y = sin( pi/2 x+3), and is

                                          y = 0.

Answer:

22.07 ft & 9.32 ft

Step-by-step explanation:

by sines rule :

20/sin 65° = r/sin 90° = y/sin 25°

r = 20×sin 90°/sin 65° = 20/0.9063

= 22.07 ft

y = 20×sin 25°/sin 65° =

20× 0.4226/0.9063

= 9.32 ft

Answer:

D

Step-by-step explanation:

Answer:

The area of the composite figure is 188 m^2

Step-by-step explanation:

Let's work with the square first.

Given,

Length of one side of the square = 6m

We know,

Area of square region = ( Length of one side of the square)^2      sq. unit

                                     = [tex]6^{2}[/tex]  m^2

                                     = 36 m^2

Again,

Length of the rectangle = (13 + 6) m = 19 m

Breadth of the rectangle = 8 m

We know,

Area of the rectangular region = (Length X Breadth)     sq. unit

                                                   = ( 19 X 8 ) m^2

                                                    = 152 m^2

∴ The total area = (36+152) m^2

                           = 188 m^2

So, the area of the composite figure is 188 m^2.

Answer:

break it in three rectangles!

let the rectangles be A B and C

For A = 4×2

For B 3× (4-2)

For C = 4×3

Total area 26cm²
