Answer:

Rectangular prism

I chose a box of cereal.

Part 1)List the dimensions of your box. Be sure to include the units (in, cm, ft, etc.).

Length: 20 cm

Width: 8 cm

Height: 32 cm

Part 2).

 Describe the shape of the cross-section when the box is cut parallel to the base.

The shape of the cross-section would be a rectangle in dimensions.

20 cm x 8 cm

Part 3)

What is the surface area of the box? 

surface area=2*area of the base + perimeter of the base*height

area of the base=20*8=160 cm²

perimeter of the base=2*[20+8]-----> 56 cm

height=32 cm

surface area=2*160+56*32------> 2,112 cm²

the answer part 3) is

2,112 cm²

Part 4)

What is the surface area of the box if it is scaled up by a factor of 10?

we know that

surface area of the larger box =[scale factor]²*surface area original box

scale factor=10

surface area original box=2,112 cm²

so

surface area of the larger box=10²*2,112-----> 211,200 cm²

the answer part 4) is

211,200 cm²

Part 5) 

What is the volume of the box?

volume of the box = L*W*H 20*8*32-5,120 cm³

the answer Part 5) is

5,120 cm³

Part 6) 

What is the volume of the box if it is scaled down by a factor of 1/10?

we know that

the volume of the smaller box =[scale factor]³volume original box

scale factor=1/10

volume original box=5,120 cm³

so

volume of the smaller box =[1/10]³*5,120 5.12 cm³

the answer part 6) is

5.12 cm³

The length is 6 in., the width is 2 in., and the height is 16 in.

Answer:

Step-by-step explanation:

Appeasement is the policy of making concessions in order to avoid a conflict. In the 1930’s it became the dominant French and British international policy toward Germany and other aggressive nations. The League of Nations had been created to peacefully resolve international disputes. However, without the United States as a member of any military force, it was ineffective at preventing belligerent nations from violating agreements.
When Italy invaded Ethiopia and Japan invaded Manchuria and China, the League could do nothing but impose economic sanctions. Adolf Hitler realized that democracies sought to avoid a confrontation and continued to test their limits. First, he remilitarized the Rhineland then turned his sights on a region of German speakers in Czechoslovakia known as the Sudetenland.
In September 1938, British Prime Minister Neville Chamberlain met with Hitler in Munich to discuss his demands. The Sudetenland held most of Czechoslovakia’s border defenses, heavy industries, and banks. Without consulting Czech authorities, however, Chamberlain pledged to give Germany all the areas with a German population of more than 50%. France was persuaded to agree. Hitler then demanded all the Sudetenland and Britain and France agreed to his demands. Chamberlain returned to Great Britain claiming he had secured “peace for our time.”
Appeasement was not without its critics, however. Winston Churchill believed in a firm stand against Nazi Germany. When Germany seized the remainder of Czechoslovakia in March 1939, it was clear that appeasement had failed. Chamberlain resigned and Churchill became the new Prime Minister of Great Britain.
---------------------------------------
“When I think of those four terrible years and I think of the 7million young men who were killed, the 13 million who were maimed and mutilated… I have said before, and what I say now to all the world – in war, whichever side may call itself the victor, there are no winners, but all are losers. It is those thoughts which have made me feel that it was my prime duty to strain every nerve to avoid a repetition of the Great War in Europe.”
― Neville Chamberlain
---------------------------------------
“An appeaser is one who feeds a crocodile, hoping it will eat him last.”
― Winston S. Churchill


Directions: After reading about appeasement, answer the following questions.
1. What is the best definition for “belligerent” as it is used in the 1st paragraph? Highlight your answer
a. Weak
b. Hostile
c. Peaceful
d. Isolationist
2. What made the League of Nations ineffective?



3. What was Neville Chamberlain’s justification for his policy of appeasement?



4. Based on the Munich Agreement and resulting events, what adjective most likely describes Hitler’s view of Chamberlain? Highlight your answer
a. Intimidating
b. Wise
c. Gullible
d. Bold
5. Do you think Churchill’s quote accurately describes the relationship between Hitler and Chamberlain? Explain why or why not.



6. Think of a time you made a concession in order to avoid a conflict. Explain what the conflict was and why you gave in. How would the outcome be different if you had not given in?

Step-by-step explanation:

Solve for the variable in the following equation: 1 / 6c + 1 / 3 = - 2
A. c = −30

B. c = 26

C. c = −14

D. c = 12

Answers

Answer: C. C=-14

Step-by-step explanation:

Given

(1/6)c+1/3=-2

Multiply both sides by the LCM of 1/6 and 1/3(Least Common Multiple)

6[(1/6)c+1/3]=(-2)(6)

c+2=-12

Subtract 2 on both sides

c+2-2=-12-2

c=-14

Hope this helps!! :)

Please let me know if you have any questions

Answer:

C. c = −14

Step-by-step explanation:

Combine multiplied terms into a single fraction

[tex]\frac{1}{6} c+\frac{1}{3} = - 2[/tex]

[tex]\frac{1c}{6} +\frac{1}{3} =-2[/tex]

Multiply by 1

[tex]\frac{1c}{6} +\frac{1}{3} =-2[/tex]

[tex]\frac{c}{6} +\frac{1}{3} =-2[/tex]

Subtract [tex]\frac{1}{3}[/tex] from both sides of the equation

[tex]\frac{c}{6} +\frac{1}{3} =-2[/tex]

[tex]\frac{c}{6} +\frac{1}{3} -\frac{1}{3} =-2-\frac{1}{3}[/tex]

Subtract the numbers

[tex]\frac{c}{6} +\frac{1}{3} -\frac{1}{3} =-2-\frac{1}{3}[/tex]

[tex]\frac{c}{6} =-2-\frac{1}{3}[/tex]

Subtract the numbers

[tex]\frac{c}{6} =-2-\frac{1}{3}[/tex]

[tex]\frac{c}{6} =-\frac{7}{3}[/tex]

Multiply all terms by the same value to eliminate fraction denominators

[tex]\frac{c}{6} =-\frac{7}{3}[/tex]

[tex]c \frac{c}{6} =6(-\frac{7}{3} )[/tex]

Cancel multiplied terms that are in the denominator

[tex]c \frac{c}{6} =6(-\frac{7}{3} )[/tex]

c = 6 [tex](-\frac{7}{3} )[/tex]

Multiply the numbers

c = 6 [tex](-\frac{7}{3} )[/tex]

c = - 14

Ratios are used to re;ate quantities of different measurements

The ratio of Sam's shells to thandeka's shells is 2:3

The quantity is given as:

Sam = 8 shells

Thandeka = 12 shells

To represent the given parameters as ratio, we have:

Ratio = Sam : Thandeka

So, we have:

Ratio = 8 : 12

Divide by 4

Ratio = 2 : 3

Hence, the ratio of Sam's shells to thandeka's shells is 2:3

A tourist attraction experienced a 3.75% fall in visitor numbers in June, compared to the previous month due to bad weather There were 121660 visitors in June How many visitors were there in May? B) In July there were 4.5% more visitors than in May What was the percentage increase in visitor numbers from June to July?

Answers

Answer:

(A) 126400

(B) 8.57%

Step-by-step explanation:

(A) According to the scenario, calculation of the given data are as follows,

Visitors in June = 121660

Let visitors in May = X

Difference in visitors number in June = 3.75% decrease

So, we can calculate the visitors number in may by using following formula,

Number of visitors in June = X - 3.75%X

121660 = 96.25%X

X = (121660 × 100) ÷ 96.25

X = 126400

Hence, Number of visitors in may = 126400

(B). Difference in visitors in July than in May = 4.5% increase

So, Number of visitors in July = 126400 + (126400 × 4.5%)

= 126400 + 5688

= 132088

Now, we will calculate increase in percentage by using following formula,

Increase percentage = (132088 - 121660)  ÷ 121660

= 10428 ÷ 121660

= 0.0857 or 8.57%
