Complete question:
Marvin is painting three squares shaped like the one below if it takes him exactly 4 cans of paint to paint square 3, five cans of paint to paint square 2 to how many cans of paint should he need to paint square one
Picture of squares is attached.
Answer:
9 cans of paint.
To paint square 1, he needs 9 cans of paint.
Step-by-step explanation:
Given that to paint square 3, four cans of paint are needed.
Therefore, let's take area of the square 3 as 4.
i.e a² = 4
Solving further, we have :
\( a = \sqrt{4} \)
a = 2
We can say, each side of square 3 = 2 units
To paint square 2, five cans of paint are needed. Let's take the area of 2 to be 5.
i.e b² = 5
Solving further, we have :
\( b = \sqrt{5} \)
We can say, each side of square 2 = \( \sqrt{5} \) units
Using Pythagoras theorem, we have that the area of the square of a hypotenuse in a 90° angle is equal to the sum of the areas of the other two squares.
Therefore,
\( h^2 = 2^2 + \sqrt{5}^2 \)
h² = 4 + 5
\( h = \sqrt{9} \)
h = 3 units.
We now know one side of the square 1 is 3 units.
Area of square 1 = 3²
Area = 9.
Therefore to paint square 1, he needs 9 cans of paint.

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.

∠6 and ∠8 are ___ angles. (same options as first one)
∠1 and ∠5 are ___ angles. (same options as first one)
Answers
Answer:
∠1 and ∠2 are supplementary angles.
∠6 and ∠8 are vertical angles
∠1 and ∠5 are corresponding angles.
Step-by-step explanation:
∠1 and ∠2 lie on a straight line which will always add up to 180 degrees or supplementary.
∠6 and ∠8 lie opposite each other on the transversal (intersecting line) and are equal.
<1 and <2 are Supplementary angles
<1 and <5 are Corresponding angles
<6 and <8 are Vertical angles
Given that d II e
when a transversal intersects two parallel lines the following conditions are true:
Supplementary angles are those angles when the sum of two angles is equal to 180 degrees. Since <1 and <2 are on either side of the transversal their sum is equal to 180 degrees hence why it's a supplementary angle.
Vertical angles form 4 angles when a line intersects them and the two angles are opposite to each other. In this case <6 and <8 are opposite each other hence why they are vertical angles.
Corresponding angles are the angles that are in the same position on each of the parallel lines and on the same side of the transversal. In this case both <1 and <5 are on the same side of the transversal on each of the parallel lines hence why they are corresponding angles

Answers
Answer:
10
Step-by-step explanation:
The easiest way to find a percentage of a given number is to represent the percentage as a decimal or fraction,and thenmultiply it by the given number.
40% as a decimal is 0.4, so to find 40% of 25, we multiply 25 by 0.4:
25 x 0.4 = 10
Answer:
10
Step-by-step explanation:
Multiply 40/100 by 25 (convert 25 to 25/1 if needed), which gives you 10. You can also convert 40/100 to the decimal 0.4, and multiply that by 25, which also gives you 10.

Answers
The table that represents a linear relationship that is also proportional is:
x - 2 0 2
y - 0 2 4
This is because the ratio between y and x is constant, which is the definition of proportionality. In this case, the ratio is 0/(-2) = 2/0 = 4/2 = 0, which is undefined but still a constant. The other tables do not have a constant ratio between y and x.

I will tell you how to solve one of the more complex expressions; the technique is the same for the rest
Let's take the very last expression
4y + 3y + 3x - 6y -10 - 2
To simplify,
group like terms:
=(4y + 3y - 6y) + 3x +(-10 -2)

Rewriting with x before y gives
3x + y - 12
and there is a matching 3x + y - 12
4y + 3y + 3x - 6y -10 - 2 ⇔ 3x + y - 12

42 + 2n ≥ 80, so n ≥ 19
42 + 2n ≥ 80, so n ≥ 36
42 + 2n ≤ 80, so n ≤ 36
Answers
Answer:
42 + 2n ≥ 80, so n ≥ 19
Step-by-step explanation:
Naomi's earnings for one day = $ 42,
Also, she earns extra $2 for each CD she sells,
Thus, the extra earning for n CDs = 2n dollars,
So, her total earning for a day if she sells n CDs = ( 42 + 2n ) dollars,
If Naomi wants to earn at least $80 per day,
Her total earning ≥ 80 dollars,
Answer:
First. 42 + 2n ≥ 80, so n ≥ 19
Step-by-step explanation:
Because you see at least $80 so its just less or same 80. ANd we need to find the minimum number of CDs, but 36 is big, I choose 19.
