Answers

Answer:

x =11

Step-by-step explanation:

Using the triangular law which states that the sum of interior anggle of a triangle is equal to exterior angle

From the diagram

Interior angles = 5x +10 and 58

Interior angle = 11x+2

Equate both expressions

5x + 10 + 58 = 11x+2

5x - 11x = 2 - 10 - 58

-6x = 2-68

-6x = -66

x = -66/-6

x = 11

Hence the value of x is 11

calculate the rise and run to find the slope of the line

Answers

Answer:

Step-by-step explanation:

To find the slope of the line, you can use the formula rise/run.

Every time the graph moves one unit across the x-axis, it moves three spaces up. Therefore,

Rise = 3

Run = 1

Now to plug this into our formula:

3/1 = 3

The slope of the line is 3.

Step-by-step explanation:

4(2a + 2) = 8(2 - 3a)

Distribute.

8a + 4 = 16 - 24a

Add 24a to each side.

32a + 4 = 16

Subtract 4 from each side.

32a = 12

Divide 32 from each side.

a = [tex]\frac{3}{8}[/tex]

Step-by-step explanation:

The value v of your quarters (in cents) is a function of n, the number of quarters you have.
1.)Draw an input-output diagram to represent this function.
2.) Write an equation that represents this function.

Answers

The equation that represents this function is v = 0.25n

Let the quarter of a dollar $0.25 or 25 cents

If the value v of your quarters (in cents) is a function of n, then;

v = 0.25n

To get an input-output diagram to represent this function, w will vary the value of n and get the corresponding value of x;

If n = 1

v = 0.25(1)

v = 0.25

If n= 2

v = 0.25(2)

v = 0.5

If n = 3

v = 0.25(3)

v = 0.75 etc.

The equation that represents this function is v = 0.25n

A baseball player reaches first base 3 out of 10 times he is at bat. If the baseball player bats 80 times, about how many times will the player reach first base?

Answers

Answer:

I think the answer is 24.

Step-by-step explanation:

I think the answer is 24 because if the baseball player hit the bat and ran the base 3 out of 10 times, then you would multiply 8 x 3 to get 24 out of 80. I don't know if this is the correct answer, this is just what I think it may be.

Louisiana Purchase DBQ(I know its a lot.. its due in 45 minutes so take your time :) I only have 123 points but if you do this you can have 100)Task:DBQ: Analyze the documents within the DBQ: Louisiana Purchase. Then write an analytical paragraph that explains how the purchase of the Louisiana Territory impacted the U.S.A. and Jeffersons presidency. Use the information provided in the following documents as well as readings and notes from this unit to support the response.Document A:In 1800, when the armies of French ruler Napoleon Bonaparte moved across Europe, pressuring Spain into a corner, the Territory of Louisiana (New Orleans) and a huge slice of land controlled by Spain in the now central United States (an estimated 827,987 sq. miles in size) was ceded back to France by Spain via the Treaty of San Ildefonso. On April 1, 1803, the United States of America was comprised of lands east of the Mississippi River, including a handful of states (17), and the Illinois, Indiana, Michigan and Mississippi Territories. At that time, besides the French Territory of Louisiana; modern-day Florida was still governed by Spain, and in the far west, excluding the British-controlled Oregon Country in the northwest, all available lands were still in the hands of Spain. In 1801, U.S. President Thomas Jefferson began his pursuit of just the French City of New Orleans (French Orleans Territory) in an effort to gain control of Mississippi River access; his $10 million offer was initially rejected by the French.1.) What did the Treaty of San Ildefonso accomplish? 2.) How large was the Louisiana Territory? 3.) Why would Jefferson want to control access to the Mississippi River? How would control of the Mississippi impact the U.S.?Document B:In 1801, U.S. President Thomas Jefferson began his pursuit of just the French City of New Orleans (French Orleans Territory) in an effort to gain control of Mississippi River access; his $10 million offer was initially rejected by the French. Over the next year Napoleon was actively involved in his growing European military campaign against Britain, as well as other political conflicts in the Americas; apparently stretched-thin, he tired of his Louisiana Territory (and needing focus and funds) he finally wavered, and on April 30, 1803 he authorized the sale of the entire French Territory of Louisiana for $15 million, which included the City of New Orleans; justifiably, President Jefferson was jubilant. The nation-changing Louisiana Purchase subsequently almost doubled the size of the United States overnight. This massive transfer of land included all of present-day Arkansas, Oklahoma, Missouri, Kansas, Nebraska and Iowa; most of Colorado, South Dakota, Montana and Wyoming, as well as significant parts of North Dakota, Minnesota, Texas and Louisiana.Parts of it also extended into what is now Canada for a short period of time. Eventually Spain ceded (lost) all of its territories to the United States, beginning in Florida in 1819, as the modern-shape of the U.S.A. finally came together. 4.) How much money did Napoleon sell the Louisiana Territory to the U.S.for? 5.) What did the purchase of Louisiana do to the size of the United States? Document C:6.) Who do you think the men in this picture are? 7.) What do you think is happening in this picture?Document D:8.) What countries owned the three major territories of North America?9.) Based on the map above, what conclusions can be drawn about the Louisiana Purchase? (How could domestic and international affairs have been impacted? 10.) How could the purchase impact under-represented groups (children, indentured servants, enslaved people, Native Americans, women, and working class)? 11.)
