Si un celular Cuesta 4500 y tiene un descuento de 76%cuamto vq a pagar por el teléfono
USPshnik [31]

De acuerdo con las definiciones de precio a pagar, porcentaje de descuento y porcentaje remanente, el precio a pagar por el celular es $ 1080.

<h3>¿Cuánto cuesta un celular con descuento? </h3>

En esta situación una persona recibe un descuento por la compra de su celular, el precio a pagar es el producto de multiplicar el coste <em>sin descuento</em> y el porcentaje remanente en forma fraccionaria. El porcentaje remanente se calcula al restar el descuento del cien por ciento. A continuación, procedemos al cálculo requerido:

x = 4500 × (1 - 76/100)

x = 1080

De acuerdo con las definiciones de precio a pagar, porcentaje de descuento y porcentaje remanente, el precio a pagar por el celular es $ 1080.

A baseball field is in the shape of a square. The
lina2011 [118]
Since the distance in between each plate is 90ft. We know from home to 1st is 90ft. To get to 2nd from first is also 90ft. So 90 + 90 is 180ft.

Now this question is weird because it could be asking how far would a baseball player would have to run to get to 1st then 2nd

Or

Could be asking the distance from Home to 2nd without going to 1st. So just a straight line from home to 2nd.

If that’s the case we need to use the Pythagorean theorem

Our setup would be 90^2 + 90^2 = c^2
Adding A and B will get us 16200. Now we need to divide to get to the other side. But C is squared. So we need to Square root 16200. Which is 127.28ft.
