why do we learn properties of real numbers?


answer quick :D

Answers

Answer:

The properties of the Real Number System will prove useful when working with equations, functions and formulas in Algebra, as they allow for the creation of equivalent expressions which will often aid in solving problems. In addition, they can be used to help explain or justify solutions.

Understanding the properties of real numbers will help us simplify numerical and algebraic expressions, solve equations, and more as you progress in studying algebra. In other words, the properties or axioms of real numbers are just one of many basic foundations of mathematics

Over the course of a year, a tractor-trailer commutes 160,000 miles across America.



a. Assuming a trucker changes his tires every 40,000 miles, and that he starts with a brand new set of tires, how many sets of tires will he use in a year?


b. If the trucker changes the oil every 10,000 miles, and he starts the year with a fresh oil change, how many times will he change the oil in a year?

Answers

Answer:

a. 4 sets of tires in a year.

b. 17 times a year.

Step-by-step explanation:

a. I just divided 160,000 by 40,000 to get 4 sets a year.

b. I divided 160,000 by 10,000 and then added 1 to get 17 times a year. I added one because the problem said that the trucker changes the oil in the beginning of the year.

Kate is going to the fair with three of her friends. It will cost $5.00 to get in and an additional $2 per ride. Create an equation to represent the cost for the whole group and then use the distributive property to expand the expression and solve the problem.
Expression: (4*5)+(2*5)=30
So I have the expression I just need to do the distributive property and I don't understand how to do that.

Answers

Answer:

5 * ( 4 + 2 ) = 5 * 6 = 30

Step-by-step explanation:

(5*4) + (2*5) = 20 + 10 = 30

5*4 = 4 people need to pay $5

2*5 = $2 for 5 rides

Distributive Property:

(5*4) + (2*5) = 5 * ( 4 + 2 )

5 * ( 4 + 2 ) = 5 * 6 = 30

Answer:

$40

Step-by-step explanation:

Ok, so the distributive property allows us to apply a number evenly over a whole set of numbers.

Equation: 4 (2 x 5) (we distribute the 4 to all terms, since each person experiences those charges.) The answer is $40 for the whole group.

Answers

Answer:

A rotation or a reflection and a translation

Step-by-step explanation:

Ik I'm 2 years late but still.

The required angle of rotation is 180° and reflection along the diagonal of the composite figure of a rectangular flag will shift the lower left triangle to the upper right.

Given that,
To describe a sequence of translations, rotations, and reflections that take the lower left triangle to the upper right triangle.

What is congruent geometry?

Incongruent geometry, the shapes that are so identical. can be superimposed to themselves.

Here,
To shift the lower left triangle to the upper right,
First It must rotate by an angle of rotation of 180° around the center of the geometry, Or it must reflect to the left diagonal.

Thus, the required angle of rotation is 180°, and reflection along the diagonal of the composite figure of a rectangular flag will shift the lower left triangle to the upper right.

Create a timeline of the life of Julius Caesar.I have a timeline, I just need somebody to put the events in order.Gaius Julius Caesar was born in Rome on July 12 or 13 100 BCE. Born into an upper class family, Caesar and some of his relatives held important positions in the government. 409 years before Julius was born the Republic of Rome was a dangerous time. The republic was being governed by a Senate. Senates were elected by the people of Rome. When Rome was growing in population, it made it more difficult to govern. Senators fought amongst themselves for more power. The working class became frustrated with the noble class governing. It lead to civil wars in the republic. Caesar aligned himself with people who were against the nobility. He started his share in politics as an advocate in 78 BCE. He decided to study oratory in Rhodes, Greece in 76 BCE. During the trip he was captured by pirates. They held him for ransom money. Caesar got the ransom money himself and got released. Instead of retiring to his homeland, Caesar decided to organize a naval force that captured the pirates. Two years later, in 74 BCE, with no official place in the Roman government or army, Caesar decided to organize a private army. This army fought off the king of Pontus who was declaring war on the Romans. All of these events made Caesar well known and a public disagreement. He moved his way through different political positions in a dishonest way. Although Roman Senates disliked Caesar, they appointed him Farther Spain. In 59 BCE, Caesar was elected into consul no matter the Senates attempts to prevent it. Consuls had significant power and Caesar took advantage of this power. He formed the first triumvirate. He combined his power with Pompey and Crassus. Crassus was a wealthy politician and Pompey was a war hero who was not liked among the Senates. Caesar decided to pay off Pompeys soldiers by giving them land to reward Pompey. People organized a riot because they disliked the idea. These riots caused chaos. Caesar took this as a distraction to get his way. This distraction allowed Caesar to become governor of Gaul. Around 58 and 50 BCE, Caesars military conquered all of Gaul. During that time, Caesars triumvirate was falling apart while he was becoming very successful. Caesar gained enemies because he was becoming successful. Caesar thought the only way to protect himself was to seize the rest of Rome. In 49 BCE he began a civil war after leading his troops across the Rubicon River into Italy. In 46 BCE he made himself a dictator of Rome. He continued defeating his enemies before returning into Rome after a year. When he made his return he adopted his great nephew, Augustus. Caesar never had a son of his own. Caesar revised the Roman calendar and made Senates more representative. He made many foreigners, citizens of Rome. Although Caesar tried his best in protecting himself, Caesars old enemies and some of his supporters devised a plan to assassinate him. On March 15, 44 BCE, Caesars enemies killed him in the Senate House. Augustus, Caesars nephew, eventually took over in 32 BCE. Caesar made a long line in history of emperors.
