A quotient is a fraction.

A sum is addition.

A variable is an unknown number shown by using a letter.

Therefore, the answers for quotient and variable in this picture should be switched. However, the negative sign has to be included, so the quotient should be a -9/y.

One month Dante rented 2 movies and 3 video games for a total of$22 . The next month he rented 4 movies and 8 video games for a total of$57 . Find the rental cost for each movie and each video game.

Answers

Answer:

x = $1.25; y = $6.50

Step-by-step explanation:

Let x be the cost of movies and y be cost of video games.

Month 1 has 2x+3y = 22

So here x = (22-3y)/2 and y = (22-2x)/3

Month 2 has 4x+8y =57

Here x = (57-8y)/4 and y = (57-4x)/8

Now you have two options: Find the y or the x. I will demo the x and you can try the y if you wish.

(22-2x)/3 = (57-4x)/8

176-16x = 171-12x

-4x = -5

x = 1.25

Now with the x found, you plug it into either of the y equations to figure out the other variable.

y = (22-2(1.25))/3

y = 6.5

And to double check:

y = (57-4(1.25))/8

y = 6.5

Answer:

Step-by-step explanation:

(sorry im not good at english) because there is no right triagle in which the length of the side of the right angle is greater than the length of the hypotenuse.

a triangle has at least 2 acute angles
(always true, never true, or sometimes true)

Answers

Always true. The sum of the measures of all interior angles add up to 180°.

For example, a right triangle will have a right angle (90°) and two acute angles.

An obtuse triangle has an obtuse angle (with a measure that is greater than 90°) and two acute angles.

The three interior angles of an equilateral triangle have a measure of 60 degrees (acute angles).

An isosceles triangle can have 2 angles with a measure of 30 degrees (acute angles), and an obtuse angle (120°).

Given these examples, we can infer that the correct answer is "Always true."

Answer:

The quadratic x2 − 5x + 6 factors as (x − 2)(x − 3). Hence the equation x2 − 5x + 6 = 0

has solutions x = 2 and x = 3.

Similarly we can factor the cubic x3 − 6x2 + 11x − 6 as (x − 1)(x − 2)(x − 3), which enables us to show that the solutions of x3 − 6x2 + 11x − 6 = 0 are x = 1, x = 2 or x = 3. In this module we will see how to arrive at this factorisation.

Polynomials in many respects behave like whole numbers or the integers. We can add, subtract and multiply two or more polynomials together to obtain another polynomial. Just as we can divide one whole number by another, producing a quotient and remainder, we can divide one polynomial by another and obtain a quotient and remainder, which are also polynomials.

A quadratic equation of the form ax2 + bx + c has either 0, 1 or 2 solutions, depending on whether the discriminant is negative, zero or positive. The number of solutions of the this equation assisted us in drawing the graph of the quadratic function y = ax2 + bx + c. Similarly, information about the roots of a polynomial equation enables us to give a rough sketch of the corresponding polynomial function.

As well as being intrinsically interesting objects, polynomials have important applications in the real world. One such application to error-correcting codes is discussed in the Appendix to this module.

The numbers are measurements of radius diameter and circumference of circles A and B. Circle A is smaller than Circle B which number belongs to which quantity? 2.5, 5, 7.6, 15.2, 15.7, 47.7

Answers

Step-by-step explanation:

a diameter is always twice the radius.

the only pairs in this list, where one number is twice the other, is :

2.5 and 5

7.6 and 15.2

so,

2.5 is the radius of A

5 is the diameter of A

7.6 is the radius of B

15.2 is the diameter of B

15.7 is then the circumference of A (as the smaller of the remaining 2 numbers).

47.7 is the circumference of B.

this is also proven by the formula for the circumference of a circle : c = 2×pi×r

Yousef, who remained in California, looked forward to their return. This Afghan American family, however, found themselves dodging gunfire on their return date, trying to force their way into the crowds of people all around the airport at the capital, Kabul. Everyone was trying to get out of the country. Afghanistan's government had collapsed and the Taliban, a militant group that ran Afghanistan in the late 1990s, had seized power again. U.S. troops had been in Afghanistan for 20 years, ever since they helped remove the Taliban from power in 2001. The United States and other Western nations also helped set up a government."Eight Families From California Left Behind"In 2021 the U.S. decided to end its longest war and withdraw its soldiers from the country. Suddenly, however, the government fell and chaos gripped Kabul. In August, U.S. troops hurried to get Americans and allies out of the country, and the last U.S. soldier left on August 31. Yousef's wife and children were among eight families from El Cajon who were left behind. Yousef's family and several other families finally got out of Afghanistan. The Cajon Valley Union School District and their representative in Congress, Republican Darrell Issa, assisted them. Several of the families spoke to reporters last week. Yousef asked that only his first name be used in this story because he still has relatives in Afghanistan who could be at risk. The parents described running with their kids as gunfire whizzed overhead. One father said he was beaten by the Taliban. They said they were kept from getting to the airport by Taliban checkpoints.They said they are grateful to be back in the U.S., but that they worry about the family members unable to get out."Safe At Home Right Now Thanks To God And All Of You""My kids are now safe at home right now thanks to God and all of you," Yousef said.He asked, however, that people not forget the many others left behind. These include U.S. citizens, as well as people with permission to live in the U.S., and Afghans who are at risk because they helped the American government. For the past 20 years, Afghans have worked with U.S. forces to oppose the Taliban. Yousef held a folder that he said contained the documents of 30 people from Afghanistan who qualified for a special immigrant visa. They should be in the United States, he said, but they are still trapped in Afghanistan, desperate to escape.President Joe Biden has said between 100 and 200 Americans were left behind when U.S. troops completed their withdrawal August 31. Many of those left behind are Afghan Americans. The State Department has given no estimate for others who hope to leave Afghanistan. These include U.S. green card holders, people who have permission to live in the United States. Other Afghans received the special visas because they helped Americans during the 20-year war. Congressman Issa said there might be more U.S. citizens and others who were left behind than the U.S. government admits. Yousef said he felt helpless being in California, thousands of miles away, fearing the life he and his family had built would come to a halt and his wife and children would be trapped in Afghanistan ruled by the Taliban. He and his family are all U.S. citizens. They came to this country on a special immigrant visa after Yousef worked for the U.S. government in Afghanistan."U.S. Authorities Escort Family To Airport"Yousef said Issa's team arranged a time for his family to go to the airport with an escort from U.S. authorities. He described talking to Issa's team from where he was in California. At the same time, he was navigating his family through the chaos in Afghanistan.His family returned home to California on Friday, September 3. The first thing he did was take them to IHOP, the International House of Pancakes. It's their favorite restaurant.He hopes more of those happy moments will wipe away the deeply distressing memories his kids have. His 7-year-old son, his youngest, has been talking about the violence."They are talking about it, about the gunfire, and being scared of the Taliban, but we hope they forget all that," said Yousef. He wants them to return to their lives as regular American kids.Questions:Imagine that you are one of Yousefs children. How are you feeling before this trip?How are you feeling during this trip? How are you feeling after you get home from this trip? The four moons are now called the _________________ in his honor
