The type of transformation which maps the triangle ABC to A'B'C' is given by reflection and the vertex of B' after reflection is B''

Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point. The line of reflection is the line that a figure is reflected over. If a point is on the line of reflection then the image is the same as the pre-image. Images are always congruent to pre-images.

The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Given data ,

Let the triangle be represented as ΔABC

Now , the transformed triangle is A'B'C'

where the triangle is reflected along the x axis

So , the reflected triangle is ΔA'B'C'

Now , the triangle ΔA'B'C' is reflected along the line x = -2

So , the reflected triangle is ΔA''B''C''

And , the vertex of B' after reflection is B''

Hence , the transformation is reflection of triangle ABC

Answer:

The percentage discount given for the handbag is 90.48%.

Step-by-step explanation:

From the question, the following can be obtained:

D = Total discount on the two items = $1946.60

T = Total amount spent on the two items = $1940.40

r = Percentage discount given for the ring = 25%, or 0.25

h = Percentage discount given for the handbag = ?

H = Amount spent on the handbag = ?

Since Helene spent $458.40 less on the ring than on the handbag, therefore we have:

R = Amount spent on the ring = H - $458.40

From the above, we have:

T = H + R

T = H + H - $458.40

T = 2H - $458.40 …………………… (1)

Substituting T = $1940.40 into equation (1) and solve for H, we have:

$1940.40 = 2H - $458.40

$1940.40 + $458.40 = 2H

$2,398.80 = 2H

H = $2,398.80 / 2

H = $1,199.40

Since,

R = H - $458.40 ……………………. (2)

By substituting H = $1,199.40 into equation (2), we have:

R = $1,199.40 - $458.40

R = $741

Amount of discount on ring = r * R = 25% * $741 = $185.25

Amount of discount on handbag = D - Amount of discount on ring = $1946.60 - $185.25 = $1,761.35

h = Amount of discount on handbag / H = $1,761.35 / $1,199.40 = 0.90483406965992, or 90.483406965992%

Rounding to 2 decimal places, we have:

h = 90.48%

Therefore, the percentage discount given for the handbag is 90.48%.

Answer:

The original weight of the box was 14.36 ounces

Step-by-step explanation:

Percentages

The height of the macaroni boxes of a certain company decreased by 6%. Let's call x to the original weight of the box.

Calculating 6% of the price:

6/100*x = 0.06x

Subtracting from the original price:

x - 0.06x = 0.94x

This is the discounted price and it's known to be 13.5 ounces, thus:

0.94x=13.5

Dividing by 0.94:

x = 13.5/0.94

x = 14.36 oz

The original weight of the box was 14.36 ounces

Answer:

-28 degrees Fahrenheit

Step-by-step explanation:

Since it changed -4 every hour for 7 hours, you would do -4 x 7 to get the answer, which equals -28. So your answer is -28 degrees Fahrenheit if I'm not mistaken.

Answer:

y = 4x - 2..............................

Answer:

(x, y) ⇒ (-y, x)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.

Rotation is the flipping of a figure about a point. If a point A(x, y) is rotated 90 degrees counterclockwise about the origin the new location of the point is at A'(-y, x).

Given a triangle with vertices at  E (2, -4). F (3, 6) And G (8, -7). If the triangle is rotated 90 degrees counterclockwise about the origin, the new location is at:

E'(4, 2), F'(-6, 3) and G'(7, 8).

The rule (x, y) ⇒ (-y, x) was used

Answer: 72 miles.

Step-by-step explanation:

We know the relationship:

Distance = speed*time.

Then we can write the equation for distance as a function of time for Ali as:

A(t) = 12mph*t

where t is time in hours.

Fatimah's equation will be:

F(t) = 18mph*(t - 2h)

where the -2h appears because she starts two hours after Ali.

Fatimah will overtake Ali when F(t) = A(t) (their positions are the same)

Then we need to solve:

12mph*t = 18mph*(t - 2h)

12mph*t = 18mph*t - 18mph*2h

12mph*t = 18mph*t - 36 mi

36 mi = (18mph - 12mph)*t

36mi = 6mph*t

36mi/6mph = t

6h = t

So Ali travels for 6 hours before he gets overtaken, then the total distance that Ali travels is:

A(6h) = 12mph*6h = 72 mi

Answer:

3 students are eating lunches other than salads and sandwiches.

Step-by-step explanation:

To solve this you know that there are 18 students in the cafeteria and 1/6 of them are eating salads and 2/3 are eating sandwiches right? So you would have to think about what 1/6 of 18 is so you know how many students are eating salads, and 1/6 of 18 is 3 so there are 3 students eating salads. Now, you have to find out how many students are eating sandwiches, so you need to know what 2/3 of 18 is. 2/3 of 18 is 12 so now you also know that there are 12 students eating sandwiches. Next, you have to add 12 and 3 and you get 15. Since you know that there are 18 students in the cafeteria, you have to subtract 18 by 15, and you should get 3. So 3 students are eating lunches other than salads or sandwiches.

Hope this helps you! :D
