Quick! Need help, anyone know this?

To determine the missing angle you simply subtract the angle you know from 180 because a flat line is 180 degrees. If it is a circle you subtract the number from 360. Hope this helps!

El sábado he gastado 3/5 del dinero que tenía para el fin de semana, el domingo 3/4 de

Vladimir79 [104]

Answer:

Her original amount of money can be represented by the variable x

Because we are spending one-fourth of her money, and “of” translate to multiply, we can write 1/4(x), or equivalently we can say 0.25x of her money, if you prefer decimal.

When you say 1/2 of it, this refers to the original amount of money, x, unless the problem wants you to figure how much 1/2 of the remaining amount is. So if the problem is directly asking for 1/2 of it, that would’ve half of x, or 0.5x in decimal.

Remaining was 50 pence, so the original amount minus 1/4 of the amount minus 1/2 the amount equals 50 pence or .50 giving us the equation: x-0.25x-0.5x=.50

Combine like terms on the left, and we have 0.25x=0.50.

Divide by 0.25 on both sides.

We have x equals 2.

So she started with $2. To check this, we ask ourselves does having $2, and spending 1/4 of it and spending 1/2 of it, then result to 50 pence?

Yes it does, because 2–1–0.5 does in fact equal 0.50 (50pence)

Su cantidad original de dinero puede ser representada por la variable x Debido a que estamos gastando una cuarta parte de su dinero, y "de" se traduce para multiplicar, podemos escribir 1/4 (x), o equivalentemente podemos decir 0.25x de su dinero , si lo prefiere decimal. Cuando dices la mitad, esto se refiere a la cantidad original de dinero, x, a menos que el problema quiera que calcules la mitad de la cantidad restante. Entonces, si el problema es pedir directamente la mitad, tendría la mitad de x, o 0.5x en decimal. El restante era 50 centavos, por lo que la cantidad original menos 1/4 de la cantidad menos la mitad de la cantidad es igual a 50 peniques o .50, lo que nos da la ecuación: x-0.25x-0.5x = .50 Combina términos semejantes a la izquierda, y tenemos 0.25x = 0.50 Divide por 0.25 en ambos lados, tenemos x igual a 2. ella empezó con 2 dólares. Para comprobar esto, nos preguntamos si tener 2 dólares y gastar 1/4 de ellos y gastar la mitad de ellos, ¿da como resultado 50 centavos? sí eso

The triangle ABC goes through a series of transformations, resulting in the triangle A’B’C’. The three transformations are liste

Pie

Answer:

The new co-ordinates of A ( 2 ,-6)

Step-by-step explanation:

Type of transformation change to co-ordinate point

Vertical translation up 'd' units (x,y)→(x , y+d)

Vertical translation down 'd' units (x,y)→(x , y-d)

Horizontal translation right 'c' units (x,y)→(x+c , y)

Horizontal translation left 'c' units (x,y)→(x-c , y)

Reflection over x-axis (x,y) →(x , -y)

Reflection over y-axis (x,y) →(-x , y)

Given the original vertex A ( -2 ,3)

a) First reflection over x-axis ( -2 ,3) →(-2 , -3)

b) Vertical translation down '3' units so it changes (-2 , -3)→(-2 , -3-3)

(-2,-3)→(-2 ,-6)

and

c) The Horizontal translation right '4' units

now it changes ( -2 ,-6) → (-2+4,-6)→(2 ,-6)

Final answer:-

The new co-ordinates of A ( 2 ,-6)
