Answer:

Dilate triangle ABC with scale factor 1/3, then reflect over the line segment CD.

=================================================

Explanation:

We're given that BC = 18 and EC = 6. In order to map ABC onto DEC, we need to have the triangles the same size. In other words, the triangles must be congruent and in the same location. One triangle will be on top of the other.

To make triangle ABC congruent to triangle DEC, we need to have BC = EC. Currently BC is 3 times longer than EC. So we need to dilate with a scale factor 1/3

Note how (1/3)*18 = 6. This scale factor will reduce segment BC so it goes from 18 units long to 6 units long. The same applies to the other segments of triangle ABC.

----------------------

After the dilation, triangle ABC is the same size and shape as triangle DEC. However, the two triangles are not in the same location. We would need point B to be at the same location of point E for the triangles to match up perfectly (point A and point C are already in their proper locations).

To move point B to E, we need to apply a reflection over the horizontal line CD. This will not move points A and C. Points on the line of reflection stay where they are.

---------------------

So to summarize, we apply a dilation with scale factor 1/3 to triangle ABC. This gets triangle ABC to the right size. Then we reflect over the line segment CD so that point B moves to point E's location.

d.

Answers

Answer:

c.  Manny could spend less on food and clothes and put the money towards his credit card payment.

Step-by-step explanation:

Edge 2021

Based on the information given, Manny can reduce his current debt by: C. Manny could spend less on food and clothes and put the money towards his credit card payment.

What is a credit card?

A credit card refers to a small rectangular-shaped plastic card that is issued by a financial institution (banks) to its customers, which allows them to purchase goods and services on credit, especially based on the agreement that the amount of money taken would be paid later with an agreed upon interest rate.

How to calculate monthly payment.

Mathematically, the monthly payment for a credit card is given by this formula:

[tex]M=P(\frac{r}{1-(1+r)^{-nt}} )[/tex]

Where:

P is the principal.r is the interest rate.M is the monthly payment.t is the time.n is the number of times it's compounded.

In this scenario, Manny can reduce his current debt by spending less amount of money on both food and clothes while putting the money towards his credit card payment.

Solve the following quadratic equation by rearranging and then factorising x^2 + 3x - 15 = 2x - 13

Answers

Step-by-step explanation:

x² + 3x - 15 = 2x - 13

x² + x - 2 = 0

(x + 2)(x - 1) = 0

By zero product rule, (x + 2) = 0 or (x - 1) = 0.

Hence x = -2 or x = 1.

Answer:

x = -2   & x = 1

Step-by-step explanation:

x^2 + 3x - 15 = 2x - 13 so you takeaway 2x and add 13 to the other side to get x^2 + x - 2 = 0

(x+2)(x-1) = 0 find factors of -2 that get you x

(x+2) = 0 so x = -2       (x-1) = 0  so x = 1

Bens living room is a rectangle measuring 9 yards by 150 inches. By how many feet does the length of the room exceed the width?

Answers

Answer:

14.5 ft or 14 1/2 ft

Step-by-step explanation:

36in= 1 yard

9x36= 324in (I'm guessing this is the length)

324in (length) -150in (width)= 174in

12 in= 1 ft

174/12= 14 ft 6 in

6 inches is half a foot

14.5 ft or 14 1/2 ft

solve this inequality for x: -46 -8x >22.

Answers

Answer:

Step-by-step explanation:

The key to answering this is to know that the only time you'll change the direction of the sign is when you multiply or divide by a negative number.

-46 - 8x > 22

-8x > 22 + 46

-8x > 68

x < 68/-8        (we divided by -8 so the inequality changed direction)

x < -17/2

Step-by-step explanation:

-46 - 8x > 22: Original problem

-46 - 8x + 46 > 22 + 46: Bringing all the constants to one side of the inequality

-8x > 68: Simplification

x < 68/-8 : You have to flip the inequality symbol because you are dividing by                                

                  a negative number..

x< -8.5 : The answer!!!!!

Checking your answer....

-46 - 8x > 22 : Original problem

-46 - 8(-8.5) > 22 : Substitution

-46 + 68 > 22 : Simplification

22 > 22 : Answer check successful!!!

(22 is not greater than 22 but we know that the answer cannot be -8.5 because the inequality states that x is less -8.5. This process was only for the purpose of checking not for the purpose of proving)

The speed limit sign on the freeway said 110 kilometers per hour, but the speedometer on Cesar's car is calibrated in miles per hour. How fast should Cesar drive his car to avoid a speeding ticket if 1 kilometer is about 0.62 miles?

Answers

Answer:

68.2 miles per hour

Step-by-step explanation:

Speed limit = 110 kilometers per hour

1 kilometer = 0.62 miles

110 kilometers = x miles

Cross product

1*x = 0.62*110

x = 68.2 miles

Cesar should drive at 68.2 miles per hour to avoid a speeding ticket

110 kilometers per hour = 68.2 miles per hour

This means the monarch is the ceremonial leader, but Parliament makes the laws. Unlike the United States Constitution, the British constitution is not a single document, but a group of laws and court decisions. The symbolic head is Queen Elizabeth II, who symbolizes Britains nationhood.The British legislature, or Parliament, is located in London, England. It is made up of the House of Lords and the House of Commons. At one time, members of the House of Lords inherited their seats. Today, Parliament is moving toward a combination of elected and appointed members in both houses. These members are composed of high-ranking clergy, judges, and national leaders. The head of the majority party in the House of Commons is the prime minister, the true head of the British government.Which statement best explains why the British system of government is considered a constitutional monarchy?Responses A. A king or queen is the head of state, but Parliament makes the laws. B. Some members of Parliament are elected, while others are appointed. C. The monarch has more power than the elected parliament.

Snowball did not deny that to build it would be a difficult business. Stone would have to be carried and built up into walls, then the sails would have to be made and after that there would be need for dynamos and cables. (How these were to be procured, Snowball did not say.) But he maintained that it could all be done in a year. And thereafter, he declared, so much labour would be saved that the animals would only need to work three days a week. Napoleon, on the other hand, argued that the great need of the moment was to increase food production, and that if they wasted time on the windmill they would all starve to death. The animals formed themselves into two factions under the slogan, "Vote for Snowball and the three-day week and "Vote for Napoleon and the full manger."Why does Snowball want to build a windmill?He wants to compel the animals to work harder.He wants to increase food production immediately.He wants to find a use for the stone on the farm.He wants to make the farm run more efficiently.
