We could see that the size of both images does not change, so it is not a dilation. The image is not mirrored either, so it is not a reflection. Finally, the image does not seem to change place that much from the preimage, so it should not be a translation, either. That means our answer is a rotation, because the image rotated about 180º.

Answers

Answer:

15.5

Step-by-step explanation:

Original Equation:

14 ÷ 2 + 3(4) - (6.5 - 3)

Do the Parentheses first.

6.5 - 3 = 3.5

Equation:

14 ÷ 2 + 3(4) - 3.5

More Parentheses.

3(4) = 3 ⋅ 4 = 12

Equation:

14 ÷ 2 + 12 - 3.5

Divide.

14 ÷ 2 = 7

Equation:

7 + 12 - 3.5

Add.

7 + 12 = 19

Subtract:

19 - 3.5 = 15.5

Given that,

The number of cookies made in 34 hour is 30.

Now, in order to calculate the number of cookies made in 3 hours unitary method can be used as follows,

In 34 hour the number of cookies = 30

In 1 hour the number of cookies = 30/34

Thus, in 3 hour the number of cookies = 30/34 × 3 = 2.64.

Hence, the number of cookies made with the given rate in 3 hours is 2.64.

Rise is a vertical distance.

Run is a horizontal distance.

Start at (-2, 0). To go to (3, 3) by using only horizontal and vertical segments, go up 3 unit. Now go right 5 units.

The rise is 3. The runs is 5.

what is the value of x in the equation 6x-5/2 = 2x+6​

Answers

Answer:

x= 17/8

Step-by-step explanation:

6x− 5/2=2x+6

Step 1: Simplify both sides of the equation.

6x+−5/2=2x+6

Step 2: Subtract 2x from both sides.

6x+−5/2−2x=2x+6−2x

4x+−5/2=6

Step 3: Add 5/2 to both sides.

4x+−5/2+5/2=6+5/2

4x=17/2

Step 4: Divide both sides by 4.

4x/4=17/2/4

x=17/8

What is the angle measure of angle b?
b
67°
A) 113°
C) 157°
B) 23°
D) 67°

Answers

Answer:

23 degrees

Step-by-step explanation:

You are given a right angle, which is 90 degrees. Part of the right angle is 67 degrees, so you do 90-67=23

Hope this helps ^^

Answer:

23 degrees

Step-by-step explanation:

This is because angle B and the angle that is 67 degrees are both apart of one right angle. We can solve this through a simple equation. 90 = x +67. Subtract 67 on both sides and you get X = 23 giving you the answer 23 degrees.

Question 9 of 10 Fill in the blank in the following sentence with the a below Hans y Helga son de Alemania. Son OA alemanas OB. alemana C. alemanes OD. alemn Read the following passages.Passage 1Peaceful Protests In 1957,Martin Luther King, Jr. founded the Southern Christian Leadership Conference so that he could continue to help organize and conduct more nonviolent protests for civil rights. He traveled around the country speaking about race relations and joined in many peaceful protests. He was arrested a number of times during these years. King was arrested once for joining students at a sit-in protest at a department store that refused to serve lunch to African Americans. In the spring of 1963, King was arrested again during a demonstration in Birmingham, Alabama. King had been peacefully protesting alongside many families.March to Make a DifferenceIn August of 1963, King helped to organize the March on Washington. There, he spoke to over 200,000 people from the stairs of the Lincoln Memorial. His delivered his famous "I Have a Dream" speech where he declared his hope that all Americans would one day be seen as equals. King's speech helped to bring about change to America's laws. In 1964, King was awarded a Nobel Peace Prize for his fight against racial inequality.Leaving a LegacyKing's life had a vast impact on civil rights in the United States. He is still known as one of the most important leaders in American history. His life and work are honored in many ways, including a national holiday, and many schools and public buildings are named after him. In fact, more than 900 cities have a road named after Martin Luther King, Jr. His inspiring legacy continues.Passage 2Many speakers at the March on Washington addressed the crowd. They represented different civil rights organizations, labor unions, and religions, but their messages built on each other. Everyone was focused on the same goal. Martin Luther King, Jr. was the last to speak. He delivered what would become one of the most famous speeches in history. Speaking eloquently, King referenced the country's Founding Fathers and the Bible while describing the struggles faced by African Americans. His speech was scheduled to be four minutes long, but King spoke for sixteen instead. He closed by describing his dreams for equality. King's "I Have a Dream" speech identified him as a major figure of the civil rights movement. His emotional speech has been referenced in presidential addresses numerous times, and his words have inspired generations.After the speeches, the marchers proceeded to the White House to meet with President Kennedy. They implored him to provide equality for all Americans. The march was an important catalyst for change. Two years after the march, on July 2, 1964, President Lyndon Johnson signed the Civil Rights Act, which made employment discrimination and segregation illegal. He then signed the Voting Rights Act on August 6, 1965, removing some of the barriers African Americans faced when voting. It appeared that some of King's "dream" was coming true.Select the sentence from Passage 2 that could be added to the "Leaving a Legacy" section of Passage 1 to prove the lasting impact of King's words.A His speech was scheduled to be four minutes long, but King spoke for sixteen instead.B Speaking eloquently, King referenced the country's Founding Fathers and the Bible while describing the struggles faced by African Americans.C His emotional speech has been referenced in presidential addresses numerous times, and his words have inspired generations.D After the speeches, the marchers proceeded to the White House to meet with President Kennedy.
