Answer:

2/7

Step-by-step explanation:

Since 4 out of 14 times it landed on blue, it must have a 4/14 experimental probability of 4/14 for landing on blue.  4/14 simplifies to 2/7.

Answer:

-7/3 is c

-2.9 is a

-2 5/8 is b

Step-by-step explanation:

-5/2 = -2.5

-7/3 > -2.5, so -7/3 is c

-6/2 = -3

-2.9 is very close to -3, so -2.9 is a

-2 5/8 is just a little less that -2.5, so -2 5/8 is b

Answer:

r = 105.

Step-by-step explanation:

In the quadratic formula, √r = \({\sqrt{b^{2}-4ac }\)

Where a = 1, b = -9, and c = -6. Therefore:

√r = √(-9)² - 4(1)(-6)

√r = √81 -4(-6)

√r = √81 + 24

√r = √105

Therefore, r = 105.

===========================================================

Explanation:

Let's say the tub is 30 gallons. I'm picking this number because it's the LCM of 10 and 15. Picking the LCM means that later division operations result in a whole number.

The hot tap takes 10 minutes to fill the tub. Its rate is 30/10 = 3 gallons per minute.

Rate = (amount done)/(time)

The cold tap works at a rate of 30/15 = 2 gallons per minute.

When both taps are running at the same time, they combine to a total rate of 3+2 = 5 gallons per minute. Therefore, it will take 30/5 = 6 minutes if both taps are opened.

Time = (amount done)/(rate)

-------------------------

Another approach:

The hot water tap takes 10 minutes to do 1 job. That "1 job" refers to "fill the bathtub". The unit rate here is 1/10 of a job per minute.

Meanwhile, the cold tap has a unit rate of 1/15 of a job per minute.

The combined rate is 1/10 + 1/15 = 3/30+2/30 = 5/30 = 1/6 of a job per minute.

x = number of minutes it takes to fill the bathtub if both taps are going at once.

We can say:

(unit rate)*(time) = amount done

(1/6 of a job per min)*(x minutes) = 1 job

(1/6)x = 1

x = 6 minutes is the final answer

-------------------------

Another approach:

The template for problems like this is:

1/A + 1/B = 1/C

where

We end up with the equation

1/10 + 1/15 = 1/x

This can be rearranged into

(1/10+1/15)x = 1

and also rearrange into

(1/6)x = 1

Follow the steps mentioned earlier to end up with 6 minutes as the final answer

The expression in the mathematical form will be - (19/24)t + 6. Then the correct option is B.

When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.

The expression two-thirds times t minus six plus three-fourths times t minus the expression five-eighths times t plus twelve.

Convert the sentence into a mathematical expression. Then we have

\(\rightarrow \dfrac{2}{3}t - 6 + \dfrac{3}{4}t - \dfrac{5}{8}t + 12\)

Simplify the expression, then we have

⇒ - (19/24)t + 6

The expression in the mathematical form will be - (19/24)t + 6. Then the correct option is B.

Answer:

ab² - a²b

Step-by-step explanation:

a²b⁴ - b²a⁴ can be factored as a²b²(b² - a²) which becomes a²b²(b + a)(b - a). Since the numerator and denominator both have (a + b) and ab the final answer is ab(b - a) = ab² - a²b.

Answer:

A)6

Step-by-step explanation:

Use the triangle inequality theorem, which states that the third side of a triangle can not be greater than or equal to the sum of the other two sides, and can be no less than the or equal to the difference of the two other sides.

The sum is 8+13=21

The difference is 13-8=5

So if we call our third side x, then

\(5

If the lengths of two sides of a triangle measure 8 and 13 units, using triangle inequality theorem, the length of the third side could be 6 units.

The triangle inequality theorem describes the relationship between the three sides of a triangle. According to this theorem, for any triangle, the sum of lengths of two sides is always greater than the third side.

Given the two sides be 8 and 13 units.

Let the third side be x units.

First,

8 + 13 > x

21 > x

x < 21

Second,

8 + x > 13

x > 5

Third,

13 + x > 8

True for all values of x.

So,

5 < x < 21

From the given options, only 6 satisfies our condition.

Answer: 0.25

Step-by-step explanation:

2 divided by 8 is 0.25 therefore you have a 0.25 theoretical probability of landing on yellow.

First find the volume of the cylinder.

The formula is: V=πr²h

Plug the numbers in the figure into the formula.

V=πr²h

V=π×3²×10

V=π×9×10

V=π90

V=282.743

Therefore, the volume of the cylinder is approximately 282.7in³

Find the volume of the rectangluar prism.

V=lwh

V=12×7×4

V=84×4

V=336

Therefore, the volume of the rectangular prism is 336in³

Add the volumes:

282.7+336=618.7

The volume of the composite solid is approximately 618.7in^3

Answer:

6 square units

Step-by-step explanation:

There are 4 whole squares that we can see very clearly. Next, we have the cut squares. The bigger "cut" square added to the smaller "cut" square is equal to 1 square. There are two cut squares for each side of the trapezoid, but when you add them up they are 1 WHOLE square on each side. 4+1+1=6, therefore the answer is 6 square units.

Answer:

76 Meters

Step-by-step explanation:

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.
