Final answer:

The scale factor of the dilation that transforms triangle PQR to triangle P'Q'R' does not exist. The coordinates for the reflected triangle P''Q''R'' are P''(-1, 0), Q''(0, -1), and R''(2, -1). Triangle PQR and triangle P''Q''R'' are not congruent.

Explanation:

To find the scale factor of the dilation that transforms triangle PQR to triangle P'Q'R', we can compare the lengths of corresponding sides in the two triangles. The distance between P(4, 0) and P'(1, 0) is 3, the distance between Q(0, -4) and Q'(0, -1) is 3, and the distance between R(-8, -4) and R'(-2, -1) is 6.

Since the lengths of corresponding sides are not equal, the triangles are not similar and there is no scale factor that transforms triangle PQR to triangle P'Q'R'.

To reflect triangle P'Q'R' about the y-axis, we simply change the sign of the x-coordinate for each vertex. The coordinates for the reflected triangle P''Q''R'' are P''(-1, 0), Q''(0, -1), and R''(2, -1).

Triangle PQR and triangle P''Q''R'' are not congruent because their corresponding sides have different lengths.

Answer:

x = -25

Step-by-step explanation:

Solve for x:

(2 x)/5 - 6 = -16

Hint: | Put the fractions in (2 x)/5 - 6 over a common denominator.

Put each term in (2 x)/5 - 6 over the common denominator 5: (2 x)/5 - 6 = (2 x)/5 - 30/5:

(2 x)/5 - 30/5 = -16

Hint: | Combine (2 x)/5 - 30/5 into a single fraction.

(2 x)/5 - 30/5 = (2 x - 30)/5:

(2 x - 30)/5 = -16

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of (2 x - 30)/5 = -16 by 5:

(5 (2 x - 30))/5 = -16×5

Hint: | Cancel common terms in the numerator and denominator of (5 (2 x - 30))/5.

(5 (2 x - 30))/5 = 5/5×(2 x - 30) = 2 x - 30:

2 x - 30 = -16×5

Hint: | Multiply 5 and -16 together.

5 (-16) = -80:

2 x - 30 = -80

Hint: | Isolate terms with x to the left hand side.

Add 30 to both sides:

2 x + (30 - 30) = 30 - 80

Hint: | Look for the difference of two identical terms.

30 - 30 = 0:

2 x = 30 - 80

Hint: | Evaluate 30 - 80.

30 - 80 = -50:

2 x = -50

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 2 x = -50 by 2:

(2 x)/2 = (-50)/2

Hint: | Any nonzero number divided by itself is one.

2/2 = 1:

x = (-50)/2

Hint: | Reduce (-50)/2 to lowest terms. Start by finding the GCD of -50 and 2.

The gcd of -50 and 2 is 2, so (-50)/2 = (2 (-25))/(2×1) = 2/2×-25 = -25:

Answer:  x = -25

Answer:

x = -25

Step-by-step explanation:

(2/5)x - 6= -16   (add 6 to both sides)

(2/5) x = -16 + 6

(2/5) x = -10  (multiply both sides by 5)

2x = -10 (5)

2x = -50  (divide both sides by 2)

x = -50 / 2

x = -25

Answer:$556.73

Step-by-step explanation:

Watts (1487) multiplied by the hours used daily (24) =35688

Divided by 1000 = 35.68

multiply 35.68 times the number of days (120) = $556.73

Another example:

wattage x hours used ÷ 1000 x price per kWh = $$

1487 x 2880 ÷ 1000 x $0.13 = $556.73

Answer:

$556.7328 is total cost of operating hot tub for 4 months in an outdoor spa.

Step-by-step explanation:

Power drawn by hot tub = 1487 Watts = 1.487 kiloWatt

1 Watt = 0.001 kiloWatt

Utility charges charged by the company = $0.13 / (kiloWatt hour)

Charges in 1 day or 24 hours : (1 day = 24 hours)

$0.13 / (kiloWatt hour) × 1.487 kiloWatt × 24 hours = $4.63944

4 months = 4 × 30 = 120 days (1 month = 30 days)

Total charge for operating hot tub for 4 months or 120 days:

$4.63944 × 120 = $556.7328

Answer:

a. [tex]30.36\ cm^2[/tex]

b. [tex]1.6\ cm[/tex]

Step-by-step explanation:

a. You know that the dimensions of Rectangle A are [tex]2\ cm* 3\frac{1}{5}\ cm=2\ cm* 3.2 cm[/tex]

Since Rectangle B’s dimensions are [tex]\frac{3}{5}\ cm[/tex] (which is 0.6 cm) larger than Rectangle A’s dimensions, then the dimensions of Rectangle B are:

[tex](2\ cm+0.6\ cm)( 3.2\ cm+0.6\ cm)=2.6\ cm*3.8\ cm[/tex]

Since Rectangle C’s dimensions are [tex]\frac{3}{5}\ cm[/tex] (which is 0.6 cm) larger than Rectangle B's dimensions, then the dimensions of Rectangle C are:

[tex](2.6\ cm+0.6\ cm)( 3.8\ cm+0.6\ cm)=3.2\ cm*4.4\ cm[/tex]

The find the total area of all three rectangles you must add the products obtained when you multiply their dimensions. Then:

[tex]A_t=(2\ cm* 3.2 cm)+(2.6\ cm*3.8\ cm)+(3.2\ cm*4.4\ cm)\\\\A_t=30.36\ cm^2[/tex]

b. The perimeter of a rectangle can be calculated with this formula:

[tex]P=2l+2w[/tex]

Where "l" is the lenght and "w" is the width.

Knowing the dimensions of each rectangleg, you can calculate the total perimeter as follows:

[tex]P_t=(2)[(2\ cm+ 3.2 cm)+(2.6\ cm+3.8\ cm)+(3.2\ cm+4.4\ cm)]\\\\P_t=38.4\ cm[/tex]

Then, if a 40-cm coil of wire was used to form the rectangles, the amount of wire that is left is:

[tex]40\ cm-38.4\ cm=1.6\ cm[/tex]

Using the slope formula, the slope, in simplest form, of the line that goes through (-3, 1) and (7, -14) is: [tex]\mathbf{-\frac{3}{2}}[/tex]

Recall:

Slope of a line that passes through any two points is found using the formula: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Given the two points that the line passes through are: (-3, 1) and (7, -14)

[tex](-3, 1) = (x_1, y_1)\\\\(7, -14) = (x_2, y_2)[/tex]

[tex]m = \frac{-14 - 1}{7 - (-3)} = \frac{-15}{10} \\\\m = -\frac{3}{2}[/tex]

Final answer:

To find the area of a square when given its perimeter, divide the perimeter by 4 to find the side length and then square this length. Thus, a square with a perimeter of 32 inches has an area of 64 square inches.

Explanation:

If the perimeter of a square is 32 inches, we can calculate the length of one side by dividing the perimeter by 4, because a square has 4 equal sides. So each side is 32 inches ÷ 4, which equals 8 inches.

Once we have the side length, we can calculate the area of the square. The area of a square is determined by squaring its side length (side length × side length). In this case, the area would be 8 inches × 8 inches, which equals 64 square inches.

Therefore, the area of the square with a perimeter of 32 inches is 64 square inches.

Answer:

The price was increased by 17.15%

Step-by-step explanation:

step 1

we have that

[tex]100\%+3.8\%=103.8\%=103.8/100=1.038[/tex]

Let

x -----> the price of a certain item

we know that

If a price increases by 3.8% a total of 5 times

then

The new price will be equal to multiply the original price by 5 times 1.038

so

[tex]x(1.038)(1.038)(1.038)(1.038)(1.038)=x(1.038)^5[/tex]

step 2

we have that

[tex]100\%-1.4\%=98.6\%=98.6/100=0.986[/tex]

we know that

If a price decreases by 1.4% a total of 2 times

then

The new price will be equal to multiply the actual price by 2 times 0.986

The actual price is [tex]x(1.038)^5[/tex]

so

[tex]x(1.038)^5(0.986)(0.986)=x(1.038)^5(0.986)^2=1.1715x[/tex]

[tex]1.1715-1=0.1715[/tex]

convert to percentage

[tex]0.1715*100=17.15\%[/tex]

therefore

The price was increased by 17.15%

Answer: The price increased by 17.149618%.

Step-by-step explanation:

Given that the price of a certain item increases by 3.8% = 0.038 a total of 5 times.

So every time the price was (1 + 0.038) = 1.038 times the original price.

So after 5 times the price is = [tex]1.038^5=1.205[/tex] times the original price.

Then it decreased by 1.4% twice. So the new price is = [tex]1.205\cdot\left(1-0.014\right)^{2}=1.17149618[/tex] times the original price.

So the percentage increase is = [tex]\left(1.17149618-1\right)\cdot100 \%=17.149618 \%[/tex]

To expand the polynomial expression (2x + 4) (3x2 + 5x + 7), we will use the rectangle (or area) method. This involves drawing a rectangle divided into six regions, each representing a product of a term from the first binomial and a term from the second trinomial.

First, draw a 2x3 rectangle, with the dimensions representing the two terms in the first binomial and the three terms in the second trinomial.

Label the length of the rectangle with the three terms from the second trinomial, 3x2, 5x, and 7.

Label the width of the rectangle with the two terms from the first binomial, 2x and 4.

Fill in each of the six regions by multiplying the term at the end of the row by the term at the top of the column. For example, the top-left region would be 2x multiplied by 3x2, giving 6x3.

Continue filling in the other five regions: 2x times 5x is 10x2, 2x times 7 is 14x, 4 times 3x2 is 12x2, 4 times 5x is 20x, and 4 times 7 is 28.

Final answer:

To divide 5 by 3/7, we multiply 5 by the reciprocal of 3/7 which is 7/3, resulting in 35/3 or 11 2/3.

Explanation:

To calculate 5 divided by 3/7, we invert the fraction 3/7 and multiply by 5. It’s the same as multiplying 5 by the reciprocal of 3/7. The reciprocal of 3/7 is 7/3. Therefore:

5 × 7/3 = 5 × (7 ÷ 3)

5 × 7/3 = (5 × 7) ÷ 3

5 × 7/3 = 35/3

5 × 7/3 is 11 with 2 left over or, in other words, it is 11 2/3.

Remember, when you divide by a fraction, you are essentially calculating how many times that fraction goes into the number. So here, 5 divided by 3/7 is asking how many groups of 3/7 there are in 5, which is why we multiply by the reciprocal.

Let's plug in the variables one by one.

6g - 2h

plug in 5 for g and 4 for h

6(5) - 2(4)

multiply

30 - 8

subtract

→ 22

2(g + 1)

plug in 10 for g

2(10 + 1)

→ 22

4g + 5h

plug in 1 for g and 4 for h

4(1) + 5(4)

multiply

4 + 20

add

24

Therefore, the answers that have a value of 22 are 6g - 2h and 2(g + 1)

Answer: 6g-2h when g=5 and h=4

and 2(g+1) when g=10 .

Step-by-step explanation:

1) 6g-2h  

when g=5 and h=4, then we have

6(5)-2(4)=30-8=22

2) 20 g  when g=2, we have

20(2)=40 ≠22

3) 2(g+1) when g=10 , we have

2(10+1)=2(11)=22

4) 4g+5h  when g=1 and h=4, we have

4(1)+5(4)=4+20=21≠22

Hence, the required answer is : 6g-2h when g=5 and h=4

and 2(g+1) when g=10 .
