Answer:

La cantidad que Javier paga como impuesto, A es de 1.200 €

La cantidad que Antonio paga como impuesto, B es 900 €

El importe que paga Elvira como impuesto, C es de 1.000 €

Step-by-step explanation:

Dejemos que 'A', 'B' y 'C', representen la cantidad que pagan Javier, Antonio y Elvira respectivamente, y que 'k' represente la constante de proporcionalidad, por proporcionalidad inversa, tenemos;

A = k / 1500, B = k / 2000, C = k / 1800

A + B + C = 3100

∴ k / 1500 + k / 2000 + k / 1800 = 3100

Simplificando la ecuación anterior usando una calculadora gráfica da;

31 · k / 18 000 = 3100

k = 18.000 × 3.100 / 31 = 1.800.000

k = 1.800.000

La cantidad que Javier paga como impuesto, A = 1.800.000 / 1.500 = 1.200

La cantidad que Antonio paga como impuesto, B = 1.800.000 / 2.000 = 900

La cantidad que paga Elvira como impuesto, C = 1.800.000 / 1.800 = 1.000

Jim read 24 pages in 40 minutes on Tuesday and 18 pages in 24 minutes on Wednesday. Are the ratios of pages read to minutes on T
IRISSAK [1]

Answer: Not proportional


Step-by-step explanation:

Ratio of pages read by Jim on Tuesday to minutes =\frac{24}{40}=\frac{3}{5}=3:5

Ratio of pages read by Jim on Wednesday to minutes =\frac{18}{24}=\frac{3}{4}=3:4

But \frac{3}{5}\neq \frac{3}{4}

Therefore, the ratios of pages read to minutes on Tuesday and Wednesday are not proportional.

What is the volume of the rectangular prism? . choices: (63yd^3) (7yd^3) (22.5yd^3) (189yd^3)​
Alexxx [7]

Answer: (7yd^3)

Step-by-step explanation:

Width= 3*\frac{1}{3}

Length= 7*\frac{1}{3}

Height= 9*\frac{1}{3}

Width= 1

Length= 2.33333333333...

Height= 3

1*2.33333333333*3= 6.99999999999

6.99999999999 is round up to 7

So that would be (7yd^3)
