Answer:

200 soles

Step-by-step explanation:

De la pregunta anterior, se nos da un descuento del 20%.

Por lo tanto, la fórmula para resolver la pregunta anterior es:

Precio nuevo = Precio inicial - (Porcentaje de descuento × Precio inicial)

De la pregunta anterior,

Precio nuevo = 160 soles

Precio inicial = x

Porcentaje de descuento = 20% = 0.2

Por eso:

160 = x - (20% x x)

160 = x - 0.2x

160 = 0.8 veces

Dividir ambos lados por 0.8

160 / 0.8 = 0.8 / 0.8

x = 160 / 0.8

x = 200 soles

Por lo tanto, el Precio Inicial que es el precio antes de la venta es de 200 soles.

Answer:

x = 7[tex]\sqrt{2}[/tex] and y = 7

Step-by-step explanation:

Since this is 45 45 90 triangle, each leg is the same length so y = 7 too and x is always [tex]a\sqrt{2}[/tex]  so x = 7[tex]\sqrt{2}[/tex]

The values of [tex]x[/tex] and [tex]y[/tex] are required.

The required values are

[tex]x=9.9\ \text{units}[/tex]

[tex]y=7\ \text{units}[/tex]

The given triangle is a right angled triangle.

Two given angles are [tex]90^{\circ}[/tex] and [tex]45^{\circ}[/tex]

The sum of the angles is [tex]180^{\circ}[/tex]

The missing angle is

[tex]180-(90+45)=45^{\circ}[/tex]

Since, the two angles are equal the side opposite the angles will also be equal.

So,

[tex]y=7[/tex]

Applying the Pythagoras theorem.

[tex]7^2+7^2=x^2\\\Rightarrow x=\sqrt{7^2+7^2}\\\Rightarrow x\approx 9.9[/tex]

Answer:

96 cookies.

Step-by-step explanation:

I don't love the wording of the question, but here's what I see:

Lisa Friday: 24

Lisa Saturday: 36

Maria total: 36

Cookie total: 96

-----------------------------------------------------

I can't really tell from how the question is worded if Maria's total was the total of what Lisa made, and she did it all on Saturday, or if Maria baked Lisa's Saturday number of cookies.

If 96 is the wrong answer, then try:

Lisa Friday: 24

Lisa Saturday: 36

Maria total: 60

Cookie total: 120
