(There is no image provided.)
Answers
See the attached picture for the answers:
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.

If the perimeter of a square is 32 inches, what is the area
Answers
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.

either Laine or Alejandro. If the ratio of "Laine votes" to "Alejandro votes” was 29:21, how
many votes did Alejandro receive? What percent of the votes did Laine receive?
Answers
Answer:
Alejandro received 6.51 million of votes
Laine received 58% of votes
Step-by-step explanation:
If the ratio of "Laine votes" to "Alejandro votes” was 29:21, then the number of "Laine votes" was 29x and the number of "Alejandro votes” was 21x. In total, 15.5 million votes were cast. So
29x + 21x = 15.5 million
50x = 15.5 million
x = 0.31 million
Then
the number of "Laine votes" [tex]=29\cdot 0.31=8.99[/tex] million
number of "Alejandro votes” [tex]=21\cdot 0.31=6.51[/tex] million

Which of the following equations correctly shows the relationship between the values of x and the values of y?
Answers
Answer~ A. y=3x-4
Explanation~ Look at the X column. Start with the first row, which is 5 in the x column and 11 in the y column. Looking back at the equation. As you can see, it has the same variables that are in the table. Replace the x with the 5 from the table.
*Remember to put the 5 in parenthesis; you must always do this when plugging in numbers into your equations*
If done correctly, your equation should now look like this:
y=3(5)-4
Following PEMDAS, the order you solve order of operations, you must first multiply, as Multiplication is before Subtraction. So, you must multiply the 5 and 3. 5×3=15, so, now your equation should look like:
y=15-4
Simply subtract 4 from 15, and you should get 11. Therefore,
y=11
Continue this process down through the table to double check your work.

What is 5 divided by 3/7
Answers
it would be 35/3 or 11 2/3
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.
Suppose the price of a certain item increases by 3.8% a total of 5 times, and then decreases by 1.4%
a total of 2 times. By what overall percent did the price increase?
Answers
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]

Diego moves the shape down, turns it 90 degrees clockwise, then moves the shape to the right. Draw the location of the shape after each move.HELP!!!
Answers
The shape moves from its original position, point A, to a point down from A, point B, after the first move. Even after a 90-degree clockwise rotation, because we are considering the shape as a point, it will still be at point B. The final move to the right places the shape at point C. The final position of the shape is at point C.
Explanation:For the purpose of illustrating this problem, let's assume that the original placement of the shape is at point A. Now, based on the movements described, here are the steps:
Move the shape down: This results in a downward shift from point A, let's say to point B. Turn it 90 degrees clockwise: The direction of a shape after a 90-degree clockwise rotation changes, but if we consider the shape as a simple point, its location would still be at point B. Move the shape to the right: From point B, if we move the shape rightwards, it will now be at a new location, let's say point C.
The final location of the shape will be at point C, which is down and to the right of the initial position, point A, after a clockwise rotation.

Draw a rectangle with six regions to expand (2x + 4) (3x2 + 5x + 7).
Answers
To expand (2x + 4) (3x^2 + 5x + 7), draw a rectangle with six regions, multiply the terms in each region and add them together. The final expanded form is 6x^3 + 22x^2 + 34x + 28.
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.
Combine like terms to get the final expanded form: 6x3 + 22x2 + 34x + 28.

Step-by-step explanation:
An outdoor spa (hot tub) draws 1487 watts to keep the water warm. If the utility company charges $0.13 per kilowatt-hour, how much does it cost to operate the spa for four months during the winter (24 hours per day)? Assume each month has 30 days.
Answers
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

what is the first need to solve (2/5) x -6=-16
Answers
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

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]

Answers
Answer:
r<17
Step-by-step explanation:
Distribute -3 through parentheses --> r + 10 < 6r+9+6 (r + 3)
Take out the oppisities --> r + 10 < 9 + 18
Move constant to the right and change the sign r < 27 -10
Subtract --> r < 17
Label each angle as acute, obtuse, right, or straight and estimate the measure in degrees.
Answers
Answer:
7) Obtuse, I didn't use a protractor, so I'm estimating about 130 degrees.
8) Straight, all straight lines are equal to 180 degrees.
9) Acute, I estimated about 30-40 degrees, again, no protractor used.

Answers
Answer:
−1 1/2
Step-by-step explanation:
i took the test <3
The subtraction of the given expression by the number line is -3/2.
The given expression is:
[tex]-1 \dfrac{1}{3} - \dfrac{1}{6}[/tex]
The improper fraction of [tex]-1 \dfrac{1}{3} =- \dfrac{4}{3}[/tex]
So, the given expression can be written as:
[tex]-\dfrac{4}{3} - \dfrac{1}{6}[/tex]
Since LCM of (3, 6) = 2
[tex]-\dfrac{4}{3} - \dfrac{1}{6} =\dfrac{-2\times 4 - 1}{6}\\\\ -\dfrac{4}{3} - \dfrac{1}{6} = -\dfrac{9}{6}\\\\ -\dfrac{4}{3} - \dfrac{1}{6} = -\dfrac{3}{2}\\\\[/tex]
Now according to the number
This subtraction will be done, if we add 1/6 toward the left side of the number line.
Hence,
The subtraction:
[tex]-\dfrac{4}{3} - \dfrac{1}{6} = -\dfrac{3}{2}\\\\[/tex]
The procedure by number line is attached below.

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 .
