Step-by-step explanation

The scale factor of triangle ABC to triangle DEF is 1/6.

Compare corresponding side lengths:

I observed that a side length of triangle ABC (2 units) is 6 times smaller than the corresponding side length of triangle DEF (12 units).

This initial comparison hinted at a scale factor of 1/6.

Checked other side lengths:

To confirm, I verified that the other side lengths also have a ratio of 1/6.

AB = 2 units, DE = 12 units (2/12 = 1/6)

AC = 4 units, DF = 24 units (4/24 = 1/6)

BC = 2 units, EF = 12 units (2/12 = 1/6)

Since all corresponding side lengths have a ratio of 1/6, this confirms that triangle ABC is a scaled-down version of triangle DEF with a scale factor of 1/6.

Answer:

Let the no. Of students from Indiana be x

Let the no. Of students from the rest of the country and abroad be y

x = 3y (Given) (i)

x + y = 884 (Given) (ii)

Subtract equation (ii) from 1

x -3y = 0

-(x+y = 884)

-4y = -884

Therefore y = 221

Therefore no. Of students from the rest of the country and abroad is 221

Substituting the value of y in (i)

x = 3 x 221

Therefore x = 663

Therefore no. Of students from Indiana is 663

Answer:

It's C. 1/8 ÷ 2

So think of it like this she starts off $32 negative and subtract 3 from each box of cards she makes . So each box of cards she will make $8 that being said

32/8 =4 (it will take 4 box of cards to pay off her booth expense).

Sales would be 11x 4 =44

Expenditures would be 3x4 =32 (the amount used to make cards ) +32(the amount paid for the booth)

Which in total would be $64

Sidney needs to sell [tex]\( \boxed{4} \)[/tex] boxes of cards to cover her expenditures, totaling [tex]\( \$44 \)[/tex] in sales and expenditures.

To determine when Sidney's sales will cover her expenditures, we set up the following equations:

1. Cost equation:

  Total cost C consists of booth cost [tex]\( \$32 \)[/tex] plus material cost [tex]\( \$3 \)[/tex] per box:

  [tex]\[ C = 32 + 3n \][/tex]

  where n is the number of boxes of cards sold.

2. Revenue equation:

  Total revenue [tex]\( R \)[/tex] is obtained from selling each box for [tex]\( \$11 \)[/tex] :

  [tex]\[ R = 11n \][/tex]

3. Break-even point:

  To find when sales cover expenditures, set [tex]\( R = C \)[/tex]:

  [tex]\[ 11n = 32 + 3n \][/tex]

  Simplify and solve for n :

  [tex]\[ 11n - 3n = 32 \][/tex]

  [tex]\[ 8n = 32 \][/tex]

  [tex]\[ n = \frac{32}{8} = 4 \][/tex]

4. Calculation:

  - Number of cards: Sidney needs to sell 4 boxes of cards.

  - Sales: Total revenue [tex]\( R \)[/tex] at break-even point:

    [tex]\[ R = 11 \cdot 4 = \$44 \][/tex]

  - Expenditures: Total cost C at break-even point:

    [tex]\[ C = 32 + 3 \cdot 4 = \$44 \][/tex]

Sidney will cover her expenditures after selling 4 boxes of cards, where her total revenue from sales equals her total costs, including booth fees and material costs. This ensures she breaks even in terms of financial outlay versus income from sales.

Sidney needs to sell 4 boxes of cards to cover her expenditures, resulting in total sales of [tex]\( \$44 \)[/tex] and total expenditures of [tex]\( \$44 \)[/tex].

The expressions that are equivalent to 2(2x + 1) are A. 4x + 2 and B. 2(1 + 2x).

The expression 2(2x + 1) can be simplified by distributing the 2 to both terms in the parentheses. This gives us 2 * 2x + 2 * 1, which simplifies to 4x + 2. Therefore, option A (4x + 2) is equivalent to 2(2x + 1).

We can also distribute the 2 to the terms inside the parentheses in option B (2(1 + 2x)). This gives us 2 * 1 + 2 * 2x, which simplifies to 2 + 4x, also equivalent to 2(2x + 1).

Option C (2(2x) + 1) is not equivalent because it simplifies to 4x + 1, not 2(2x + 1).

Option D (2x + 1 + 2x + 1) is not equivalent because it simplifies to 4x + 2, not 2(2x + 1).

Option E (x + x + x + x + 1 + 1) is not equivalent because it simplifies to 4x + 2, not 2(2x + 1).

[tex]120=xy+2x^{2}+2y^{2}[/tex]  ---> equation B (area of the constructed figure)

substitute the equation A in equation B

[tex]120=(y+5)y+2(y+5)^{2}+2y^{2}\\ 120=y^{2}+5y+2(y^{2}+10y+25)+2y^{2}\\ 120=y^{2}+5y+2y^{2}+20y+50+2y^{2}\\120=5y^{2}+25y+50\\5y^{2}+25y-70=0[/tex]

Find the value of x

[tex]x=y+5 ----> x=2+5=7\ cm[/tex]

Find the perimeter of rectangle

[tex]P=2(x+y)=2(7+2)=18\ cm[/tex]

Answer:

The perimeter of the rectangle = 18 cm

Step-by-step explanation:

* The figure consists of one rectangle and four squares

* Lets put the dimensions of the rectangle and the four squares

- The width of the rectangle is x

∵ The length of the rectangle is 5 cm longer than the width

∴ The length of the rectangle is x + 5

∵ Area the rectangle = L × W

∴ Area rectangle = x(x + 5) = x² + 5x ⇒ (1)

* There are four squares constructed each in one side

  of the rectangle

- Two squares constructed on the length of the rectangle

∴ The length of the sides of the squares = x + 5

∵ Area the square = S²

∴ Its area = (x + 5)² ⇒ use the foil method

∴ Its area = x² + 10x + 25

∵ They are two squares

∴ Its area = 2x² + 20x + 50 ⇒ (2)

- Two squares constructed on the width of the rectangle

∴ The length of the sides of the squares = x

∴ Its area = x²

∵ They are two squares

∴ Its area = 2x² ⇒ (3)

- Area rectangle = x(x + 5) = x² + 5x ⇒ (3)

* Now lets make the equation of the area of the figure by

 adding (1) , (2) and (3)

∴ The area of the figure = 2x² + 20x + 50 + 2x² + x² + 5x  

                                         = 5x² + 25x + 50⇒ (4)

∵ The area of the figure = 120 cm² ⇒ (5)

* Put (4) = (5)

∴ 5x² + 25x + 50 = 120 ⇒subtract 120 from both sides

∴ 5x² + 25x +50 - 120 = 0 ⇒ add the like term

∴ 5x² + 25x -70 = 0 ⇒ divide both sides by 5

∴ x² + 5x - 14 = 0 ⇒ factorize it to find the value of x

∴ (x - 2)(x + 7) = 0

* Lets equate each bracket by 0

∴ (x - 2) = 0 ⇒ x = 2

∴ (x + 7) = 0 ⇒ x = -7 ⇒ rejected no -ve side length

∴ x = 2

* Now lets find the dimensions of the rectangle

∵ Length rectangle = x + 5

∴ Length rectangle = 2 + 5 = 7 cm

∴ Width rectangle = 2

∵ The perimeter of the rectangle = 2(L + W)

∴ The perimeter of the rectangle = 2(2 + 7) = 18 cm

* The perimeter of the rectangle = 18 cm

Final answer:

To compare the area of two squares, calculate each area by squaring the length of a side, then form a ratio. A square with a side length twice that of another has four times the area.

Explanation:

Calculating the Area of a Square and Comparing to Another Square

To calculate the area of a square, you need to multiply the length of one side by itself since all sides of a square are equal in length. If we have a square with a side length of 4 inches, its area would be 4 inches × 4 inches = 16 square inches. Now, if we take another square with dimensions that are twice the first square, its side length would be 8 inches.

The area of this larger square is 8 inches × 8 inches = 64 square inches. When we compare the area of the larger square to the smaller one, we create a ratio. The ratio of their areas is 64 to 16, or simplified, 4 to 1. This means the larger square has an area that is four times as big as the area of the smaller square.

The correct answer is:

y = -4x + 3

Answer:

The equation "y = -4 x + 3" represents a line parallel to the line shown on the graph.

Step-by-step explanation:

The line shown on the graph corresponds to the equation "y = -4 x + 8".

All linear functions with the same slope are represented by parallel lines.

The slope of the function of the graph is -4 and the slope function of the answer is -4, too. Therefore both of them represents parallel lines.

The function "y = 4 x - 1" has got different slope, so it represents a different line.

Answer:

A. 72 in^2.

Step-by-step explanation:

What you do is you have to use the formula for a surface area of a rectangular prism which is:

A=2(wl+hl+hw).

Your height is 3 inches.

Your width is 2 inches.

Your length is 6 inches.

You will plug that into the formula.

A=2(2*6+3*6+3*2).

A=2(12+18+6)

A=2(36)

A=72 in^2 is your answer.

Answer:

The Surface Area is 72 square inches

Step-by-step explanation:

2*3=6 and 6*2=12

2*6=12 and 12*2=24

6*3=18 and 18*2=36

36+24+12=72

Answer:

P = 95%

Step-by-step explanation:

The average is:

[tex]\mu = 3\ minutes[/tex]

The standard deviation is:

[tex]\sigma = 0.25\ minutes[/tex].

We want the probability that the red light lasts between 2.5 minutes and 3.5 minutes

This is:

[tex]P(2.5 <X <3.5)[/tex]

Now we must transform these values to those of a standard normal distribution to facilitate calculation by using the probability tables.

[tex]P(2.5-3 <X- \mu<3.5-3)\\\\P(\frac{2.5-3}{0.25} <\frac{X- \mu}{\sigma}<\frac{3.5-3}{0.25})\\\\P(-2<Z<2)[/tex]

This is:

[tex]P(-2 <Z <2) = P(Z <2) - P(Z <-2)[/tex] ---------- (By the symmetry of the standard normal distribution)

When you search for the normal standard table, you get the following value:

[tex]P(Z <2) = 0.9772\\\\P(Z <-2) = 0.0228\\\\P(-2 <Z <2) = 0.9772 - 0.0228\\\\P(-2 <Z <2) = 0.9544[/tex]
