Answer:

She earns $7.

Step-by-step explanation:

5 percent of 140 is 7. You can think of this as taking ten percent of 140.0 by moving the decimal point one place to the left, 14, and then since 10 divided by 2 is 5, divide that by 2 and you get 7.

The expression for the area of the shaded region is s^2 - pir^2

<h3>Area of composite figure</h3>

The formula for calculating the area of the shaded part in the given equation is expressed as:

Area area of square. - area of circle

Since

Area of square = s^2

Area of circle = pir^2

substitute

Area of shaded part = s^2 - pir^2

Hence the expression for the area of the shaded region is s^2 - pir^2

Joseph, después de hacer compras, piensa de la siguiente forma: "Gasté los 3/5 de lo que no gasté y aún me quedan S/. 60 más de

earnstyle [38]

Answer:

Joseph tenía 240 soles

Step-by-step explanation:

Tenemos lo siguiente

Cantidad total = Cantidad gastada + Cantidad restante.

Sabemos que Cantidad gastada = 3/5 Cantidad restante y que Cantidad restante = Cantidad gastada + 60.

Sea x la cantidad gastada e y la cantidad restante. Tenemos las ecuaciones

$x = \frac{3}{5}y, y = x+60$

Reemplazando la segunda en la primera, tenemos que

$x = \frac{3}{5}(x+60)= \frac{3}{5}x + 36$ (aquí simplemente distribuímos la multiplicación.

Restando 3/5 x a ambos lados, tenemos que

$x-\frac{3}{5}x = \frac{2}{5}x = 36$

Multiplicando por 5 y dividiendo por dos ambos lados, tenemos que

$x=\frac{5\cdot 36}{2} = 90$

Es decir, Joseph gastó 90 soles. Entonces y = 90+60 = 150 soles.

Es decir, en total, Joseph tenía 150+90= 240 soles.
