An aquarium has a base in the shape of a trapezoid. The base is 80 cm long at the front, 50 cm long at the back, and 30 cm wide (from front to back). The height is 100 cm. What is the volume of the aquarium in litres?

Answers

Answer:

The volume of the aquarium is 195 litres.

Step-by-step explanation:

The volume ([tex]V[/tex]), measured in cubic centimetres, of the aquarium is equal to the area of the base multiplied by the height. That is:

[tex]V = \frac{1}{2}\cdot (L+l)\cdot w\cdot h[/tex] (1)

Where:

[tex]L[/tex] - Long leg length of the aquarium, measured in centimetres.

[tex]l[/tex] - Short leg length of the aquarium, measured in centimetres.

[tex]w[/tex] - Width of the aquarium, measured in centimetres.

[tex]h[/tex] - Height of the aquarium, measured in centimetres.

If we know that [tex]L = 80\,cm[/tex], [tex]l = 50\,cm[/tex], [tex]w = 30\,cm[/tex] and [tex]h = 100\,cm[/tex], then the volume of the aquarium is:

[tex]V = \frac{1}{2}\cdot (80\,cm+50\,cm)\cdot (30\,cm)\cdot (100\,cm)[/tex]

[tex]V = 195000\,cm^{3}[/tex]

If we know that a litre equals 195000 cubic centimetres, then the volume of the aquarium is:

[tex]V = 195000\,cm^{3}\times \frac{1\,L}{1000\,cm^{3}}[/tex]

[tex]V = 195\,L[/tex]

The volume of the aquarium is 195 litres.

Answer:

ASA, SAS, SSS, SAS, ASA

Step-by-step explanation:

In order of attachments, left to right:

1) ASA . . . . the bisected angles are on either end of the common segment. ∆ABC ≅ ∆ADC

2) SAS . . . . the vertical angle lies between the sides congruent by virtue of the midpoint being X. ∆RSX ≅ ∆PQX

3) SSS . . . . two sides and the shared segment are congruent. ∆KLM ≅ ∆KGM

4) SAS . . . . the parts of the bisected angle lie between the congruent sides and the common side. ∆WXZ ≅ ∆YXZ

5) ASA . . . . the common segment lies between parts of a bisected angle and ones that are given as congruent. ∆PQR ≅ ∆SQR

100 is the total

100-45=55

55 percent=people supporting home team

55%=946 people

946/55

17.2=1%

Answer:

W = 10 cm

Step-by-step explanation:

Area of a Triangle and a Rectangle

The area of a triangle of base B and height H is:

[tex]\displaystyle A_t=\frac{BH}{2}[/tex]

The area of a rectangle of width W and length L is:

[tex]A_r=WL[/tex]

We are given the base of the triangle B=6 cm and the height H=8 cm, thus the area is:

[tex]\displaystyle A_t=\frac{6*8}{2}= 24\ cm^2[/tex]

The area of the rectangle is 5 times the area of the triangle, thus:

[tex]A_r=5*24\ cm^2=120\ cm^2[/tex]

If we know the area of the rectangle and its length, we can find the width by solving for W:

[tex]\displaystyle W=\frac{A_r}{L}[/tex]

The rectangle has a length of L=12 cm, thus:

[tex]\displaystyle W=\frac{120}{12}=10\ cm[/tex]

W = 10 cm

Simplify the midpoint of PR.
Q (2b, 2c)
R (2a+2b, 2c)
Pl(0,0)
S (2a, 0)

Answers

Answer:

The midpoint of PR is;

(a + b, c)

Step-by-step explanation:

Here, we want to get the coordinates of the midpoint of PR

To get these, we make use of the midpoint formula

Mathematically, that will be;

(x,y) = (x1+y1)/2, (x2+y2)/2

(x1,y1) = (0,0)

(x2,y2) = (2a+2b, 2c)

The midpoint is thus;

(2a+2b)/2 , 2c/2

= (a + b, c )

Answer:

Which of the sets of ordered pairs represents a function? (5 points) A = {(1, −5), (8, −5), (8, 7), (2, 9)} B = {(7, −4), (7, −2), (6, −3), (−9, 5)} Only A Only B Both A and B Neither A nor B

Answers

Answer:

We conclude that Neither A nor B represents the function.

Hence, the correct option is:

Neither A nor B

Step-by-step explanation:

A function relates an input to an output.

For example, a certain animal grows 30 cm each year. Thus, the height of the animal is associated with its age using the function

h (age) = age × 30

Therefore, if the age of the animal is 3 years, the height is:

h(3) = 3 × 10 = 90 cm

Set A

A = {(1, −5), (8, −5), (8, 7), (2, 9)}

Please check that there are duplicated inputs.

i.e. x = 8 is appeared twice.

Thus, set A does not represent the function because the function has repeated inputs or x-values. In other words, each input is not related to exactly one output.

Therefore, the set A of ordered pairs does not represent a function.

Set B

B = {(7, −4), (7, −2), (6, −3), (−9, 5)}

Please check that there are duplicated inputs.

i.e. x = 7 is appeared twice.

Thus, the set B does not represent the function because the function has repeated inputs or x-values. In other words, each input is not related to exactly one output.

Therefore, the set B of ordered pairs also does not represent a function.

Conclusion:

We conclude that Neither A nor B represents the function.

Hence, the correct option is:

Neither A nor B

In a moment, he said, he would ask the present company to drink a toast. But before doing so, there were a few words that he felt it incumbent upon him to say. It was a source of great satisfaction to him, he saidand, he was sure, to all others presentto feel that a long period of mistrust and misunderstanding had now come to an end. There had been a timenot that he, or any of the present company, had shared such sentimentsbut there had been a time when the respected proprietors of Animal Farm had been regarded, he would not say with hostility, but perhaps with a certain measure of misgiving, by their human neighbours. Unfortunate incidents had occurred, mistaken ideas had been current. It had been felt that the existence of a farm owned and operated by pigs was somehow abnormal and was liable to have an unsettling effect in the neighbourhood. Too many farmers had assumed, without due enquiry, that on such a farm a spirit of licence and indiscipline would prevail. They had been nervous about the effects upon their own animals, or even upon their human employees. But all such doubts were now dispelled. Today he and his friends had visited Animal Farm and inspected every inch of it with their own eyes, and what did they find? Not only the most up-to-date methods, but a discipline and an orderliness which should be an example to all farmers everywhere. He believed that he was right in saying that the lower animals on Animal Farm did more work and received less food than any animals in the county. Indeed, he and his fellow-visitors today had observed many features which they intended to introduce on their own farms immediately. What results from the human farmers visit to Animal Farm? Select two options. The farmers fear that their animals will rebel as well. The farmers are impressed with how well the farm is run. The farmers vow to implement the same kinds of systems. The farmers decide that they want to be a part of the farm.
