Answer:

1. (A) Greece has the longest coastline in Europe and is the southernmost country in Europe. The mainland has rugged mountains, forests, and lakes, but the country is well known for the thousands of islands dotting the blue Aegean Sea to the east, the Mediterranean Sea to the south, and the Ionian Sea to the west.

1. (B) Rome was built on a defensible hill that dominated the last downstream, high-banked river crossing where traverse of the Tiber was facilitated by a midstream island. This hill, Palatine Hill, was one of a group of hills, traditionally counted as seven, around which the ancient city grew.

1. (C) The fertile soil of the Po and Tiber River Valleys allowed Romans to grow a diverse selection of crops, such as olives and grains. Greece's steep mountains and surrounding seas forced Greeks to settle in isolated communities. Travel by land was hard, and sea voyages were hazardous. Most ancient Greeks farmed, but good land and water were scarce. They grew grapes and olives and raised sheep, goats, pigs, and chickens.

2. (A) Monotheism:
So mono means like one, so monotheism means that you only believe in one god. (The three religions of Judaism, Christianity, and Islam readily fit the definition of monotheism)

Polytheism:
So poly means more than one, so polytheism is the opposite of monotheism (more than one god) (for example, Hinduism, Shintoism, Thelema, Wicca, druidism, Taoism, Asatru, and Candomble).

2. (B) Jewish people believe there's only one God who has established a covenant—or special agreement—with them. Their God communicates to believers through prophets and rewards good deeds while also punishing evil. Most Jews (with the exception of a few groups) believe that their Messiah hasn't yet come—but will one day.
2. (C) Christians believe there's only one God, and he created the heavens and the earth. This divine Godhead consists of three parts: the Father (God himself), the Son (Jesus Christ), and the Holy Spirit.

2. (D) So I was not sure about the Greek, so I only did the Roman part, hope that's alright. As different cultures settled in what would later become Italy, each brought its own gods and forms of worship. This made the religion of ancient Rome polytheistic, in that they worshipped many gods. They also worshipped spirits. Rivers, trees, fields, and buildings each had their own spirit or numen. (I think)

3. (A) The Greeks made important contributions to philosophy, mathematics, astronomy, and medicine. Literature and theatre was important aspect of Greek culture and influenced modern drama. The Greeks were known for their sophisticated sculpture and architecture.

3. (B) The legacy of Ancient Rome is still felt today in Western culture in areas such as government, law, language, architecture, engineering, and religion.

(Not too sure about this one) Roman models of colonialism and of warfare also became influential.

It was due to their exceptional concrete that they were able to produce their sturdy aqueducts and bridges as well as other structures.

3. (C) The Greeks made important contributions to philosophy, mathematics, astronomy, and medicine.

3. (D) A people known for their military, political, and social institutions, the ancient Romans conquered vast amounts of land in Europe and northern Africa, built roads and aqueducts, and spread Latin, their language, far and wide.

3. (E) Though it has been thousands of years since the Roman Empire flourished, we can still see evidence of it in our art, architecture, technology, literature, language, and law.

3. (F) The Greeks pretty much invented modern mathematics, sculpture, philosophy, science, and even medicine.

Hope this helps!

Suppose you borrow money for a year at a simple interest rate of 7.2%. You pay $86.40 in interest. How much have you borrowed?

Answers

Answer:

$1200

Step-by-step explanation:

You want to know the amount borrowed at 7.2% if the simple interest for one year is $86.40.

Interest

The interest formula is ...

I = Prt

where P is the amount borrowed, r is the interest rate, and t is the number of years.

Application

Using the given values, we have ...

86.40 = P·0.072·1

P = 86.40/0.072 . . . . . . divide by the coefficient of P

P = 1200

You have borrowed $1200.

Answer: 1200

Step-by-step explanation: Linear equation. 7.2x = 100(86.40). then divide by 7.2 on each side. x=1200

Answer:

$x=-6\dfrac{7}{8}$

Step-by-step explanation:

$Solve\:9\:\dfrac{1}{4}\:+\:x\:=\:2\:\dfrac{3}{8}$

Step 1:
Convert all mixed fractions to improper fractions.
This will make it easier to add and subtract

Mixed fraction $a\dfrac{b}{c}$ can be converted to an improper fraction using

$a\dfrac{b}{c}=\dfrac{a\cdot \:c+b}{c}$

$9\dfrac{1}{4}=\dfrac{9\cdot 4+1}{4} = \dfrac{37}{4}$

$2\dfrac{3}{8}=\dfrac{2\cdot 8+3}{8} =\dfrac{19}{8}$

Step 2:
Replace every mixed fraction in the original equation with its equivalent improper fraction:
$\dfrac{37}{4}+x=\dfrac{19}{8}$

Step 3
Solve for x

$\mathrm{Move}\:\dfrac{37}{4}\:\mathrm{to\:the\:right\:side}$:
$\dfrac{37}{4}+x-\dfrac{37}{4}=\dfrac{19}{8}-\dfrac{37}{4}$
Simplify:
$x =\dfrac{19}{8}-\dfrac{37}{4}$
To calculate the right side value, multiply $\dfrac{37}{4}$ by 2 on both numerator and denominator. This will get the denominator as 8 for both fractions and we can simply subtract the numerator:

$\begin{aligned}x & = \dfrac{19}{8} - \dfrac{37 \times 2 }{4 \times 2} \\ & = \dfrac{19}{8} - \dfrac{74}{8}\\& = \dfrac{19 - 74}{8}\\& = - \dfrac{55}{8}\\\end{aligned}\\\\$
$\mathrm{Convert\:to\:mixed\:number:\:Quotient\dfrac{Remainder}{Divisor}}$
55 goes into 8 six times so the whole part(quotient) is 6
Remainder = 55 - 8 x 6 = 55 - 48 = 7
So the fractional part = remainder/divisor = 7/8
Result:
$x=-6\dfrac{7}{8}$

4. Chris and Keith went to a carnival. Chris started with 80 tickets and spent x tickets at the carnival, Keith started with 140 tickets and spent 2x tickets at the carnival. At the end of the night, they had the same number of tickets left over. How many tickets did Chris spend at the carnival?

Answers

Answer: x=20

Step-by-step explanation:

3x+80=140

3x=60

x=20

Answer: Chris spent 60 tickets at the carnival.

Step-by-step explanation:

At the end of the night, both Chris and Keith had the same amount of tickets, so:

80 - x = 140 - 2x

Now, solve the equation. Start by bringing the -2x to the left side.

80 - x + 2x = 140

Bring the 80 to the right side so the variables are isolated.

-x + 2x = 60

Add like terms.

x = 60

Check the work.

Chris had 80, spent 60, so had 20 left. --> 80 - 60 = 20

Keith had 140, spent 120 (60 *2), so also had 20 left. --> 140 - 120 = 20

So, Chris spent 60 tickets at the carnival.

Which expression has the same value as 20 − 4 ⋅ 3
a. 20 − (4 ⋅ 3)
b. (20 − 4) ⋅ 3
c. 20 + 4 − 3
d. 20 ⋅ 4 − 3

Answers

Answer:

a. 20 - (4 ⋅ 3)

Step-by-step explanation:

PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

Please note that multiplication 4 ⋅ 3 will happen before the subtraction -

If we add parentheses, we introduce a new "order". But if the parentheses are around the first operation we perform, the order stays the same!

This means that answer a. must be correct.

We verify:

20 − 4 ⋅ 3 = 20 - 12 = 8

a. 20 − (4 ⋅ 3) = 20 - 12 = 8

b. (20 − 4) ⋅ 3 = 16 ⋅ 3 = 48

c. 20 + 4 − 3 = 21

d. 20 ⋅ 4 − 3 = 80 - 3 = 77

Answer: A: 20 - (4 x 3)

Step-by-step explanation:

In the end, the final answer is 8, so we need to see which one of these options give us 8. As seen, we first must solve the multiplication, and the first option, A, solves the multiplication first because it is in parenthesis, which gives us 8, so the correct answer is A.

The stem-and-leaf plot displays data collected on the size of 15 classes at two different schools.

Mountain View School Seaside School

0 3 0, 6
Key: 2 | 1 | 0 means 12 for Mountain View and 10 for Seaside

Part A: Calculate the measures of center. Show all work. (2 points)

Part B: Calculate the measures of variability. Show all work. (1 point)

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)

Answers

To calculate the measures of center, we need to find the mean and median for each school.

For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).

Range: The range is the difference between the largest and smallest values in the dataset.

For Mountain View School:
Range: 9 - 0 = 9

For Seaside School:
Range: 9 - 0 = 9

Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.

For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4

For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5

To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.

Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice

Part A:

For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.

For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.

Part B:

For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.

For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.

Part C:

If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.
