Help please! No matter what I do I can't get it right!

Answer:

Step-by-step explanation:

The surface area of the actual ramp including the underside is 16.8 ft²

The height of the actual ramp = 1.2 feet  

The height of the model = 6 cm

A right triangular prism is a 3-dimensional triangle with two congruent triangular faces and 3 rectangular faces that connect the triangular.

here, we have,

The surface area of a right triangular prism

= (Perimeter of the base × Length of the prism) + (2 × Base Area)

Scale factor = 1.2 feet / 6 cm = 0.2 ft/cm

Actual base = 16 cm × 0.2 ft/cm = 3.2 ft

convert the units

9 cm = 9 cm × 0.2 ft/cm = 1.8 ft

10 cm = 10 cm × 0.2 ft/cm = 2 ft

The surface area of a right triangular prism

= (Perimeter of the base × Length of the prism) + (2 × Base Area)

Surface area of actual ramp

= 2(0.5 × 3.2 ft × 1.2 ft) + 2(2 ft × 1.8 ft) + (1.8 ft × 3.2 ft)

= 16.8 ft²

Hence, the surface area of the actual ramp including the underside is 16.8 ft²

Answer:

Step-by-step

first w=7

second w=3

Segments HR and HY are secants to the circle from the same point, so the products of the lengths of each secant with its external segment are equal. That is, RH times TH = YH times KH. Substituting values in gives you the equation 32 (2x - 4) = 16 (3x + 1) and solving gives you x = 9

now this one i don't understand. i got the last one but not this one.

Step-by-step explanation:

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

Explanation:

Let's find the distance between the two given values

Let a = -2.8 and b = -7.2

Subtract a and b, then apply absolute value to ensure the result isn't negative.

|a-b| = |-2.8-(-7.2)|

|a-b| = |-2.8+7.2|

|a-b| = |4.4|

|a-b| = 4.4

The distance from -2.8 to -7.2 is 4.4 units.

To go from -2.8 to -7.2, we moved 4.4 units to the left.

Let's go back to -2.8 and now move 4.4 units to the right.

So we add 4.4 onto -2.8 getting

-2.8+4.4 = 1.6

The diagram is shown below.

On a number line, the number 1.6 is the same distance from −2.8 as −7.2 the answer is 1.6.

It is defined as the representation of the numbers on a straight line that goes infinitely on both sides.

It is given that two numbers on a number line that is:

-2.8 and -7.2

To find the other number that is the same distance from −2.8 as −7.2:

Mathematically, we can write a number expression:

= -2.8 -(-7.2)

= -2.8 + 7.2

= 4.4

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division.

Accordingly, -7.2 is 4.4 units distant from -2.8.

= -2.8 +4.4

= 1.6

Thus, on a number line, the number 1.6 is the same distance from −2.8 as −7.2 the answer is 1.6.

Answer:

I don't see a chart

Answer:

The unit rate is 15.

Explanation:

Time (hours)

6: $90            90/6 = 15

12: $180         180/12 = 15

18: $270        270/18 = 15

24: $ 360      360/24 = 15

You should find the unit rate by dividing y by x. I divided all of the y's by the x's and I got 15 for all of them, which means that the unit rate is 15.

Answer:

15

Step-by-step explanation:

It is 15  becaues 15 times 4 = 60

Answer:

The surface area is the sum of the lateral area and the base area.

The lateral area is the area of the curved surface of the cone.

The lateral area can be found using the equation LA = Pirl.

Step-by-step explanation:

The surface area is the sum of the lateral area and the base area.

The lateral area is the area of the curved surface of the cone.

The lateral area can be found using the equation LA = Pirl.

Answer:

1 OVER 8

Step-by-step explanation:

Jessica paid more than Amber at lunch.

To find out, we first need to calculate the amount of tip each person left:

Amber's tip = 11.70 x 0.18 = $2.11

Jessica's tip = 12.30 x 0.15 = $1.85

Then we add the cost of the lunch and the tip for each person:

Amber's total cost = 11.70 + 2.11 = $13.81

Jessica's total cost = 12.30 + 1.85 = $14.15

So Jessica paid $0.34 more than Amber for lunch.

Answer:

m=100 N=4480 P=1706. Q= 213.25

Step-by-step explanation:

First divide 800/8= 100

100 is M

Undo division for 560x8= 4480

4480 is N

Add 100+560= 660

Solve to equations 6986/8= 873.25

subtract 873.25-660= 213.25

213.25 is Q so undo division 213.25x8= 1706

1706 is P

Add 800+4480+1706= 6986

6986 is the first part of the equation

Add 100+560+213.25= 873.25

873.25 is the answer to the equation making answer that I gave correct

6986/8= 873.25

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.

Answer:

B) 25 x 1.99$ + x = 52.74$

Step-by-step explanation:

For every song that she bought, the cost would be 1.99$. The total amount of tax would be in x, which you would add to the total cost of songs. In the end, you could find the value of x by multiplying 25 x 1.99 and subtracting it by 52.74.
