A specific brand of gourmet chocolate candy contains 7.00 gg of dietary fat in each 22.7-gg piece. How many kilograms of dietary
Oduvanchick [21]

Answer:

635599482kg

Step-by-step explanation:

A gourmet chocolate candy has 7.00 gg of dietary fat in each 22.7-gg piece

for the 22.7 piece , the gg is 7 x 22.7  = 158.9gg in total

1gg = 2204622.6218488 lbs

158.9gg in total  = 158.9 x 2204622.6218488 = 350314534.612

for the box of 4.00 lblb of candy

it is 350314534.612 x 4 = 1401258138.45lb

since our answer is needed in kilograms we convert 1401258138.45lb to kilograms

1lb = 0.453592kg

1401258138.45lb =  1401258138.45lb x 0.453592kg = 635599481.513 ≈ 635599482kg

Find the value of n<br> -2(4 + 2n)= -20
Mamont248 [21]

Answer:

n= -3

-2(4+2n) = - 20

-8+4n = -20

4n = -20+8

4n = -12

divide both sides by 4

Solve. High school pre-cal
Oliga [24]

Answer:

<em>Answer: Quadrant 4</em>

Step-by-step explanation:

<u>Graph of Functions </u>

Let's analyze the function  

\displaystyle y=\frac{x^2+3x}{x+1}

To better understand the following analysis, we'll factor y

\displaystyle y=\frac{x(x+3)}{x+1}

For y to have points in the first quadrant, at least one positive value of x must produce one positive value of y. It's evident that any x greater than 0 will do. For example, x=1 will make y to be positive in the numerator and in the denominator, so it's positive

For y to have points in the second quadrant, at least one negative value of x must produce one positive value of y. We need two of the factors that are negative. It can be seen that x=-2 will make y as positive, going through the second quadrant.

For the third quadrant, we have to find at least one value of x who produces a negative value of y. We only need to pick a value of x that makes one or all the factors be negative. For example, x=-4 produces a negative value of y, so it goes through the third quadrant

Finally, the fourth quadrant is never reached by any branch because no positive value of x can produce a negative value of y.

Answer: Quadrant 4

Given B(17,5), C(11, -3), D-1, 2), and<br> E(x, -6), find the value of x so that BC || DE.
son4ous [18]

Answer:

x=-7

Step-by-step explanation:

Remember that:

  • Two lines are parallel if their slopes are the same.
  • Two lines are perpendicular if their slopes are negative reciprocals.
  • And two lines are neither (a.k.a intersecting) if they are neither parallel nor perpendicular.

We want to find the value of x such that \overline{BC}\parallel\overline{DE}.

Therefore, the slopes of BC and DE must be equivalent.

So, let's find the slope of BC first.

BC)

We can use the slope formula:

m=\frac{y_2-y_1}{x_2-x_1}

Let B(17, 5) be (x₁, y₁) and let C(11, -3) be (x₂, y₂). Substitute:

m=\frac{-3-5}{11-17}

Subtract:

m=-8/-6=4/3

So, the slope of BC is 4/3.

DE)

Let D(-1, 2) be (x₁, y₁) and let E(x, -6) be (x, y₂). Substitute:

m=\frac{-6-2}{x-(-1)}

We know that the two slopes must be equal. So, the slope of DE must also be 4/3. Substitute 4/3 for m:

\frac{4}{3}=\frac{-6-2}{x-(-1)}

Solve for x. Simplify the right:

\frac{4}{3}=\frac{-8}{x+1}

Cross multiply:

4(x+1)=-8(3)

Multiply on the right:

4(x+1)=-24

Divide both sides by 4:

x+1=-6

Subtract 1 from both sides:

x=-7

So, the value of x is -7.

And we're done!
