Your teacher may want the numbers only, so you may have to leave off the units.

We have these approximations:

sqrt(55) = 7.416198

3*sqrt(55) = 22.248595

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

Explanation:

ABC is isosceles, meaning that the altitude (aka height) h cuts side BC into two equal pieces. BC = 6 cuts in half to 3.

Let's say point D is on BC and at the base of the altitude. In other words, D is at the midpoint. Triangle ABC is cut into two smaller triangles ABD and ADC.

Let's focus on triangle ADC, which is a right triangle. It has a horizontal side of DC = 3 and vertical side AD = h. The hypotenuse is AC = 8.

---------

Let

Apply the pythagorean theorem

a^2 + b^2 = c^2

h^2 + 3^2 = 8^2

h^2 + 9 = 64

h^2 = 64-9

h^2 = 55

h = sqrt(55) ..... exact

h = 7.416198 ..... approximate

---------

Once we determine the height of triangle ABC, we can compute the area

base = BC = 6 cm

height = AD = h = sqrt(55) cm

area = 0.5*base*height

area = 0.5*6*sqrt(55)

area = 3*sqrt(55)  .... exact

area = 22.248595 .... approximate

The units for the area are "square cm" or "cm^2".

Answer:

16/24 and 12/18, in simplest form 2/3

Step-by-step explanation:

8 parts juice

fruit and crushed ice = 3 + 9 = 12

ratio of juice to fruit and crushed ice is 8:12 or 8/12

8/12 (2/2) = 16/24

8/12 (1.5/1.5) = 12/18

in simplest form

8/12 (1/4 / 1/4) = 2/3

the ratio of the scale drawing is

1 inch on the drawing represents 180 feet in real life.

To determine the ratio of the scale drawing, we need to first find the length of the building on the scale drawing. We know that the actual length of the building is 60 feet, and the length of the building on the scale drawing is 4 inches. We can set up a proportion to find the length of the building on the scale drawing:

Actual length / Length on scale drawing = Scale factor

We can plug in the values we know:

60 feet / Length on scale drawing in inches = Scale factor

To solve for the length on the scale drawing in inches, we can cross-multiply:

60 feet * 1 inch / Scale factor = Length on scale drawing in inches

Simplifying:

Length on scale drawing in inches = 60 feet * 12 inches / Scale factor

We know that the length on the scale drawing is 4 inches, so we can plug that into the equation:

4 inches = 60 feet * 12 inches / Scale factor

Solving for the scale factor:

Scale factor = 60 feet * 12 inches / 4 inches

Scale factor = 180

Answer: The y-intercept is the initial amount Tammy earns.

Step-by-step explanation:

Always remember that for graphs, the y-intercept is the initial amount. In this case, it would be the initial amount or the very first amount Tammy earns. If the line goes through the origin (0,0), that means that Tammy earns $0.00 for 0 hours of working.

Answer:

Length = 26, Width = 52

Step-by-step explanation:

156/6 = 26

26*2=52

Answer: The length will be 52 and the width will be 26

Step-by-step explanation:

If the formular to calculate Perimeter of a rectangle is

P = 2* (L+W)

and the length L= 2W.

156 = 2* (2W+ W)

156 = 2* (3W)

156 = 6W

Solving for W

W= 26

Since in the question the Length L is 2* W(width)

L= 2* 26 = 52

I only know the first answer which is 23%

Answer:

You can check if an equation is true for all some or no values of x by simply to  try and solve the equation if you get something like x = x, then the equation  is true for all, if you get a specific answer like x=3, then it is true to some values, in simple terms. Try and solve the equation there is no other way to check unless you solve, I don't know if there is another way but this is just my intution.

Answer:

Area of five squares = 1289.09 square units

Perimeter =  194.6 units

Step-by-step explanation:

Area of square and perimeter:

   First find the length of each square, then find the area of each square.

To find the area of five squares, add all the area of each square.

Side of square1 = 27 units

\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)

Area of square1 = 27*27 = 729 square units

Area of square2 = 18*18 = 324 square units

Area of square3 = 12*12 = 144 square units

Area of square4 = 8*8 = 64 square units

Area of square5 = 5.3*5.3 = 28.09 square units

Area of five squares = 729 + 324 + 144 + 64 +28.09

                                  = 1289.09 square units

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)

                                                         = 90 + 42 + 28 + 18.7 + 15.9

                                                          = 194.6 units

I wasn't fully sure on this question sorry :(

The number of cookies prepared in an hour is \(3\frac{27}{32}\) cookies.

Given that, 8 ⅕ cookies can make in 1 ¹/₃ of an hour.

Here, 8 ⅕ can be written as 41/8 and 1 ¹/₃ can be written as 4/3.

Now, unit rate = Number of cookies/Number of hours

= 41/8 ÷ 4/3

= 41/8 × 3/4

= 123/32

= \(3\frac{27}{32}\)

Therefore, the number of cookies prepared in an hour is \(3\frac{27}{32}\) cookies.

Answer:

D.

Step-by-step explanation:

According to the dot plot,

3 students spend 0.5 minutes brushing their teeth.

2 students spend 1.5 minutes brushing their teeth.

1 student spends 2.5 minutes brushing their teeth.

2 students spend 3.5 minutes brushing their teeth.

1 students spend 4 minutes brushing their teeth.

So, the number set will be: {0.5, 0.5, 0.5, 1.5, 1.5, 2.5, 3.5, 3.5, 4}

Median: The middle number in a set that is ordered from least to greatest.

In this example, the median is 1.5

Mean: The sum of all values divided by the number of values.

In this set there are 9 values so we’ll divide the sum by 9

In this example, the mean would be:

(0.5 + 0.5 + 0.5 + 1.5 + 1.5 + 2.5 + 3.5 + 3.5 + 4) ÷ 9

18 ÷ 9 = 2

If we compare the mean to the median we can see that the mean is greater because 2 > 1.5

Answer:

5 miles

Step-by-step explanation:

1. we have to figure out how many miles of the total 43 miles victor rides to and from school by subtracting the product of five days worth of soccer practice trips from the total miles per school week but that will give us one weeks worth of school trips, so we need to divide to find how long is one days worth.

2. we know victor goes to soccer and back every school day and its a 3.6 mile round trip so we have to multiply 3.6 by 5 because thats how many days are in a week which gives us 18.

3. next, we have to subtract our product (18) from our overall mileage (43) so the equation is: 43 - 18 = x (x being the trip to school and back) giving us 25.

4. the last step is we have to divide 25 by 5 because that subtraction just gave us the entire weeks' worth of biking to school and back, we just want one day. so we will divide and get 5. victor's round trip distance to and from school is 5 miles.

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.
