Mathematics
1 answer:
Alisiya [41]3 years ago
5 0

Answer:

x ≈ 9.5 , y ≈ 15.3

Step-by-step explanation:

sin32° = \frac{opposite}{hypotenuse} = \frac{x}{18} ( multiply both sides by 18 )

18 × sin32° = x , then

x ≈ 9.5 ( to the nearest tenth )

cos32° = \frac{adjacent}{hypotenuse} = \frac{y}{18} ( multiply both sides by 18 )

18 × cos32° = y , then

y ≈ 15.3 ( to the nearest tenth )

Tres empleados de una empresa tienen que pagar 3100€ de impuestos entre todos de forma inversamente proporcional a su sueldo men
Illusion [34]

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

How do I write a real world problem that could be solved using the equation x+287= 594
Leviafan [203]

Answer:

Real-world problem using the equation x + 287 = 594...

Let's suppose you have $287 dollars in your bank account. You deposit a check and afterwards have $594 in your account. How much was the check worth?

You can then find the answer by solving for x:

594 - 287 = x

594 - 287 = 307

x = 307

So the check was worth $307!
