Si para introducirun producto al país se pagan $225 por concepto de impuestos y dicho producto cuesta $1,200
adell [148]

Complete question :

si para introducir un producto al país se pagan $225 por concepto de impuestos y dicho producto cuesta $1,200 ¿que porcentaje se cobra por impuesto?

Responder:

18,75%

Explicación paso a paso:

Dado que:

Monto cobrado por impuestos = $ 225

Costo del producto sujeto a impuestos = $ 1200

El porcentaje del precio de costo del producto que se grava:

Sea porcentaje = x%

x% * precio de coste = importe de impuestos

0.01x * $ 1200 = $ 225

12x = 225

x = 225/12

x = 18,75

Por tanto, porcentaje de impuesto = 18,75%

At best buy they have a 42" TV that sells for $1250 and is on sale for 15% off. What
marysya [2.9K]

Answer:

If the television is on sale for 15%, that means that the selling price before tax will be 100 - 15 = 5% of the original price.

1250 * 0.85 = $1062.5 ... this is your selling price BEFORE tax

Now, calculate your tax.

You would pay (1062.5) + (1062.5 * 0.065)  

= 1062.5 + 69.06 (your tax)

= 1131.56 dollars

If WXY is equilateral and WZY is<br> isosceles, find each missing measure.
timurjin [86]

Answer:

m∠1 = 60°

m∠2 = m∠4 = 39°

m∠3 = m∠5 = 21°

Step-by-step explanation:

ΔWXY is a equilateral angle,

Therefore, all angles of the the triangle are equal in measure.

m∠W + m∠X + m∠Y = 180°

3m∠W = 180°

m∠W = 60°

Since, ΔWZY is an isosceles triangle,

m∠3 = m∠5

m∠3 + m∠Z + m∠5 = 180°

m∠3 + 138° + m∠3 = 180°

2m∠3 = 180 - 138

m∠3 = 21°

Therefore, m∠3 = m∠5 = 21°

Since, m∠2 + m∠3 = 60°

m∠2 = 60 - 21

        = 39°

Since, m∠4 + m∠5 = 60°

m∠4 = 60 - 21

        = 39°

m∠1 = 60°
