Answer:

The ratio of white:milk:dark is  9:8:4

Explantion:

Let w represent white chocolate , m represent milk chocolate and  d represent dark chocolate

The ratio of white to not white is 3:4

Here not white means , it can be milk or dark chocolate

Then

w : (m+d) = 3:4 -----------------------------(1)

The ratio of not dark to dark is 17:4.

Again not dark means , it will be white or milk chocolate

Then,

(w+m) : d = 17:4  -----------------------------(2)

Representing (1) in fractions

\frac{w}{m+d} =\frac{3}{4}

4w = 3(m+d)

4w = 3m +3d

4w -3m =3d------------------------------(3)

 Representing (2) in fractions

\frac{(w+m)}{d}= \frac{17}{4}

4(w+m) = 17d

4w +4m = 17d---------------------------(4)

Subtracting (3) from (4)

4w +4m = 17d

4w -3m = 3d

(-)

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

7m = 14d

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

\frac{m}{d} = \frac{14}{7}

\frac{m}{d} = \frac{2}{1}

m:d = 2:1

Since w:(m+d)=3:4 let's make m:d a multiple of 4.

m:d = 8:4

w : (m+d) = 3:4 = 9:12

w:m:d = 9:8:4

A store pays $120 for a television. The store sells the television for $300. What is the percent of the markup
marta [7]

Answer: 150%

Step-by-step explanation:

A store buys a television for $120.

The store then sells the television for $300.

The makeup is the amount they increased the cost price by to get to the selling price.

= 300 - 120

= $180

In percentage terms it is:

= 180/120 * 100%

= 150%

Which inequality in standard form represents the<br> shaded region?
Lubov Fominskaja [6]

The figure is represented by the inequality y ≥ 5 · x² - 40 · x - 45. (Correct choice: C)

<h3>What inequality represents the figure</h3>

In accordance with the figure, we have an inequation of the form y ≥ f(x). Now we proceed to find the <em>quadratic</em> equation of the parabola:

f(x) = a · (x + 1) · (x - 9)

- 125 = a · (4 + 1) · (4 - 9)

- 125 = a · 5 · (- 5)

- 125 = - 25 · a

a = - 5

f(x) = 5 · (x + 1) · (x - 9)

f(x) = 5 · (x² - 8 · x - 9)

f(x) = 5 · x² - 40 · x - 45

The figure is represented by the inequality y ≥ 5 · x² - 40 · x - 45. (Correct choice: C)

SOLVE THIS EXTREMELY IMPORTANT EQUATION
finlep [7]

Answer:

<em>Option B; EF = ( About ) 4.47 units, Perimeter of Δ EFG = ( About ) 12.94 units</em>

Step-by-step explanation:

If we were to consider the height of this triangle EFG, it would be 4 units of length, supposedly splitting base GF into two ≅ parts, each 2 units of length. First let us name the point drawn to base GF ⇒ point H, so that the height of Δ EFG ⇒ EH. Now as EH splits GF into two ≅ parts, by Converse to Coincidence Theorem, Δ EFG ⇒ Isosceles Δ;

EH and FH are legs of a right triangle EFH, so that Pythagorean Theorem can be applied to solve for the length of EF and EG, knowing that as Δ EFG ⇒ Isosceles Δ, EF ≅ EG;

( EH )^2 + ( FH )^2 = ( EF )^2,

( 4 )^2 + ( 2 )^2 = ( EF )^2 ⇒ take square of 4 & 2,

16 + 4 = ( EF )^2 ⇒ combine like terms,

( EF )^2 = 20 ⇒ take square root on either side to solve for EF,

EF = √ 20 =<em> ( About ) 4.47 units</em> = EG,

Perimeter of Δ EFG = EF + GF + EG = 4.47 + 4 + 4.47 = <em>( About ) 12.94 units,</em>

<em>Solution; Option B</em>
