Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

f(x) = one eighth (x − 2)2 − 2
f(x) = −one sixteenth (x + 2)2 − 2

Answers

Answer:

f(x)=1/16(x-2)^2+2

Step-by-step explanation:

The Equation can be written like this:

f(x) = 1/(4p)(x -h)^2 +(k-p)

where (h, k) is the focus, and p is half the distance between focus and directrix. Here, (h, k) = (2, 6) and p=(6-(-2))/2 = 4. So the equation is ...

f(x) = 1/16(x -2)^2 +2

The cost of a trail mix at the grocery store is normally $12 per pound but now the price has increased by 30%. What is the price per pound of trail mix now that the price has increased?

Answers

Answer:

15.6

Step-by-step explanation:

The price of trail mix has increased by $12 * 30/100 = $<<12*30/100=3.6>>3.6.

So the price per pound of trail mix now is $12 + $3.6 = $<<12+3.6=15.6>>15.6.

The required new price of the trail mix is $15.6 .

What is percentage?

Percentage is a measurement to find value of given number out of hundred.

Given that,

The normal cost of trail mix at the grocery store = $12 per pound.

Als0, the price of the trail mix increased by 30%.

To find the price of trail mix after increasing the price,

Use percentage property,

Let the initial price was 100 %

So after increasing 30%, the new price becomes 130%.

The new price = 12 x 130% = 12 x 130 / 100 = 1560/100 = 15.6

The increased price of the trail mix is $15.6.

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there

Answers

Answer:

Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Zahra needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 4.75 hours and charged her $66 for parts. The total was $184.75. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.

Answers

Answer:

Step-by-step explanation:

1st Step, Find how much she paid for 4.75 hours

184.75 - 66 = 118.75

2nd Step, find how much she did in 1 hour

118.75/4.75 = 25

25 dollars per hour

After solving the equation, we found that the cost of labor per hour is $25.

Let us denote the cost of labor per hour as = "x";

The total cost consists of two components: the labor cost and the cost of parts.

We know that : the technician worked for 4.75 hours and charged $66 for parts, the total-cost is $184.75,

Using the equation:

Total Cost = Labor Cost + Parts Cost,

Substitute the given values,

$184.75 = 4.75x + $66,

Now, solve for "x",

4.75x = $184.75 - $66,

4.75x = $118.75,

Divide both sides by 4.75,

x = $118.75/4.75,

x = $25,

Therefore, the cost of labor per-hour (x) is $25.

Answers

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.

Answers

Answer:

1 1/5.

Step-by-step explanation:

To divide a fraction by another fraction you have to change the equation like "Keep, Switch, Flip".

For the problem 24/25 ÷ 4/5,

You KEEP the first fraction as is, so 24/25

Then, you SWITCH the sign from division to multiplication.

Finally, you FLIP the second fraction upside down, (the reciprocal). So it's 5/4.

The equation is now 24/25 * 5/4, which we can just multiply the numerators and denominators. (or cross cancel first)

24 * 5 = 120

25 * 4 = 100

the fraction is 120/100. Simplified, it can be divided by 10 to make 12/10, and finally divided by 2 to make 6/5, or 1 1/5.

Two angles create a straight line. The angles measure (5x-18)° and (4x + 45)° Find the value of x.

Answers

Answer:

$\huge\boxed{x=17}$

Step-by-step explanation:

It's important to note that when two angles create a straight line, they are supplementary.

This means their angle measures add up to 180° since a 180° angle is a straight line.

Since we know the measures of both angles in equation form, we can add them together and have them equal 180 to solve for x.

$(5x-18) + (4x+45) = 180$

Combine like terms:

$9x + 27 = 180$

Subtract 27 from both sides:

$9x = 153$

Divide both sides by 9:

$x = 17$

So x = 17.

Hope this helped!

Answer: x = 17

Step-by-step explanation:

Remember that supplementary angles add up to 180.

We also know that two angles create a straight line.

We have to find x in (5x-18)° and (4x + 45)°.

Now, we know that (5x-18) and (4x + 45) is 180.

Now, let's get started.

5x and 4x is equal to 9x.

Now, we have to combine the like terms.

9x + 27 = 153.

Subtract the number 153 from 180.

You get 17, so it is the answer.

Hope this helps!
