M plain candies come in various colors. According to the MM/Mars Department of Consumer Affairs, the distribution of colors for

ioda

Given that the distribution of colors for plain MM andies is as follows:

<span>Colors - Purple Yellow Red Orange Green Blue Brown
Percentage - 20% 20% 20% 10% 10% 10% 10%

Suppose one candy is taken at random from a large bag of plain MM candies, the probability that the candy is purple of orange is given by:

P(purple candy or orange candy) = P(purple candy) + P(orange candy) = 20% + 10% = 30%

A rectangle has vertices E(4,8), F(2,8), G(2,-2) and H(-4,-2). The rectangle is dilated with the origin as the center of dilatio

Leona [35]

Note: The image of G after the dilation must be G'(5,-5) instead of G'(5,5).

Given:

The vertices of a rectangle are E(4,8), F(2,8), G(2,-2) and H(-4,-2).

The rectangle is dilated with the origin as the center of dilation so that G's is located at (5,-5).

To find:

The algebraic representation that represents this dilation.

Solution:

If a figure is dilated by factor k with origin as the center of dilation, then the dilation is defined as:

$(x,y)\to (kx,ky)$ ...(i)

Let the given rectangle is dilated by factor k with origin as the center of dilation. Then,

$G(2,-2)\to G'(k(2),k(-2))$

$G(2,-2)\to G'(2k,-2k)$

The image of G after dilation is G'(5,-5). So,

$(2k,-2k)=(5,-5)$

On comparing both sides, we get

$2k=5$

$k=\dfrac{5}{2}$

So, the scale factor is $k=\dfrac{5}{2}$ .

Substituting $k=\dfrac{5}{2}$ in (i), we get

$(x,y)\to \left(\dfrac{5}{2}x,\dfrac{5}{2}y\right)$

Therefore, the required algebraic representation to represents this dilation is $(x,y)\to \left(\dfrac{5}{2}x,\dfrac{5}{2}y\right)$ .

Maria bought a bracelet. She paid $0.72 in sales tax at a rate of 6%. What was the original price of the bracelet, before tax?

VikaD [51]

Answer:

0.76 rounded don't mind my explanation

Step-by-step explanation:

in Geometry if you want a farewell you need to know the parallel lines they never touch they're always the same distance apart it's as if they don't like each other much and there's only one thing that comes between the line that passes right through each of them called the transversal line it has several angle properties just like these: vertically opposite angles are equal corresponding angles are equal alternate interior angles are equal co-interior angles equal 180* vertically opposite angles are equal corresponding angles are equal alternate interior angles are equal co-interior angles equal 180*
