An angle measures 48.4° less than the measure of its complementary angle. What is the measure of each angle?

Answers

Answer 1

Answer:

The angles are 69.2 degrees and 20.8 degrees

Step-by-step explanation:

Complementary angles, when added together, = 90°

We’ll call the first unknown angle a and the second angle b

b = a - 48.4

a + b = 90

So let’s substitute in for b in the second equation:

a + a - 48.4 = 90

2a - 48.4 = 90

2a = 138.4

a = 69.2

69.2 - 48.4 = 20.8 = b

Now, does a + b = 90?

69.2 + 20.8 = 90

This table shows the populations of the four largest cities in the state of Wyoming. How many more people live in Cheyenne than in Laramie?

Answers

Answer:

28650

Step-by-step explanation:

just subtract 59,466-30,816

The number of more people who live in Cheyenne than in Laramie given the population of each city in the state is 28,650 people

How many more people live in Cheyenne than in Laramie?

Population can be defined as the total number of people living in a particular geographical location at a period of time.

Population of Cheyenne = 59,466

Population of Laramie = 30, 816

The number of more people who live in Cheyenne than in Laramie = Population of Cheyenne - Population of Laramie

= 59,466 - 30, 816

= 28,650 people

Hence, 28,650 more people live in Cheyenne than in Laramie.

What is the equation of this graphed line?

Enter your answer in slope-intercept form in the box.

Answers

Answer:

y = 2x + 2

Step-by-step explanation:

As we know, slope intercept is: y = mx + b

m is slope and b is the y-intercept.

Looking at this problem, we can see that the line crosses the y-axis at positive 2, so that is our y-intercept. For the slope, take a point like the y-intercept, and see how many squares is has to go up before it reaches the next square to the right. In this problem the line goes up 2 squares in the time it takes to go to the right 1. So the slope is y over x, or 2 over 1, or just 2.

Y=2x+2

C′D′ is half the length of CD.

C′D′ is greater than twice the length of CD.

C′D′ and CD are equal in length.

Answers

Answer:

Step-by-step explanation:

Sila put a wrong number in her calculator

Sila jogged 12 kilometers today and wants to know how far she traveled in feet. What error did Sila make while converting from kilometers to feet ? The correct answer is Option a) Start Fraction 12 kilometers Over 1 End Fraction times Start Fraction 0.62 miles Over 1 kilometer End Fraction times Start Fraction 5280 feet Over 1 mile End Fraction = 392,832 feet.

Sila's mistake can be identified in her conversion calculation. She first needs to convert kilometers to miles and then miles to feet. Let's break down the process step by step:

1. Kilometers to Miles:

Start by converting kilometers to miles.

There are 0.62 miles in 1 kilometer.

So, the first fraction is correct:

Start Fraction 12 kilometers Over 1 End Fraction times Start Fraction 0.62 miles Over 1 kilometer End Fraction.

2. Miles to Feet:

Next, convert miles to feet.

There are 5280 feet in 1 mile. Sila's calculation is incorrect at this step. The correct fraction to use here is Start Fraction 5280 feet Over 1 mile End Fraction.

Now, let's put it all together:

- Start Fraction 12 kilometers Over 1 End Fraction times Start Fraction 0.62 miles Over 1 kilometer End Fraction times Start Fraction 5280 feet Over 1 mile End Fraction

Multiply the fractions step by step:

- 12 kilometers * 0.62 miles/kilometer * 5280 feet/mile

- This simplifies to 392,832 feet.

So, Sila's error lies in not using the correct conversion factors for both kilometers to miles and miles to feet.

The correct conversion factors should be applied in sequence, leading to the final answer of 392,832 feet traveled.

Assignment SummaryIn this assignment, you will create parallel time lines describing important developments that occurred during the rise of Muslim empires and at least one other civilization.You will create a time line that shows key dates and events from the expansion of Muslim empires, including events that took place during the growth of the following empires:Early Muslim caliphates, including the Rashidun caliphate started by Ab Bakr, the Umayyad dynasty, and the Abbasid dynastyThe Ottoman EmpireThe Safavid EmpireThe Mughal EmpireYou will also create a second time line showing events that took place during the growth of another civilization between 600 CE and 1500 CE. You may choose which civilization to research and highlight. Examples include:China, including the Tang, Song, Yuan, and Ming dynastiesThe Byzantine EmpireThe Mongol EmpireBackground InformationFollowing the death of Muhammad, early caliphs expanded Muslim empires throughout the Arabian Peninsula and into the Middle East. The Umayyad dynasty extended Muslim empires west to Spain and east into Persia. The Abbasid dynasty continued to rule much of this same territory for another five hundred years.After the fall of the Abbasid dynasty, the Ottoman Empire rose in Anatolia. As the Ottoman Empire expanded, two other Muslim empires were formed in Persia and India: the Safavid and Mughal Empires. These three empires existed in parallel for two hundred years, until the Safavid and Mughal Empires ended. During this same era in world history, several other civilizations continued to expand and develop. For example, several Chinese dynasties controlled territory in East Asia. The Byzantine Empire persisted in the eastern Mediterranean region from the 4th century CE until the 15th century CE. Also, in the 13th century CE, the Mongol Empire rapidly spread across Asia and influenced Europe and the Middle East.Historians use time lines to track the order of key events in different time periods. Time lines also create opportunities to compare and contrast events that took place in different regions. Focus your time lines on one topic, such as rulers or politics. This assignment will help you practice your historical thinking skills.
