let the lengths of two sides of the parallelogram be 4x cm and 13x cm respectively
⇒ its perimeter = 2(4x + 13x) cm = 8x + 26x = 34x cm.
∴ 34x = 210
⇔ x = 210/34 = 6.17
∴ one side = (4 × 6.17) cm = 24.68 cm and other side = (13 × 6.17) cm = 80.21 cm.

Let 3 other angles are x each
-----------------------------------
We know, sum of angles of a quadrilateral = 360
135 + x + x + x = 360
135 + 3x =360
3x = 360 - 135
3x = 225
x = 225/3
x = 75
Measure of other 3 angles = 75 each

Let the ratio be x :-
Sum of angles of a quadrilateral = 360°
=> 7x + 8x + 9x + 12x = 360
=> 15x + 21x = 360
=> 36x = 360
=> x = 360 ÷ 36
=> x = 10
Angles are :-
7x × 10 = 70
8x × 10 = 80
9x × 10 = 90
12x × 10 = 120

Let the number of bottles filled in 5 hours be ‘x’
Hence ratio of bottles filled and time (hours) are in direct proportion.
6/840=5/x
⇒6×x=5×840
⇒x=(5× 840)/6
X= 5× 140= 700 bottles
Hence, the machine will fill 700 bottles in 5 hours.

ANSWER
Vocal cords and Layrnx vibrate whenever we speak.
When we speak muscles in the larynx bring the vocal cords together. As the air rushes from our lungs out through the larynx, the from portion of the vocal cords vibrate, producing a sound. The upper portion of our throat then modifies this sound to produce speech.

| Planet | Satellite |
| Any astronomical body orbiting a star can be classified as a planet | Satellites both natural and artificial, orbit relatively close to planets or any other celestial body with a relatively bigger mass. |
| The term ‘planet’ is derived from the Greek word “planan” meaning “to wander”. | The term ‘satellite’ is derived from the Latin word ‘<i>satelles’</i> meaning ‘to follow” or “to attend to” |
| Examples of planets are Earth, Jupiter, Saturn, etc. | Examples of satellites are the Moon orbiting the Earth, Titan orbiting Saturn and Europa orbiting Jupiter |

Rayon, nylon, polyester, acrylic, and spandex are examples of synthetic fibres.
Fibres that are made by human beings are called synthetic fibres. Most synthetic fibres are obtained from coal, petroleum, and natural gas. A synthetic fibre consists of multiple units (each of which is a chemical substance), which are joined together to form a single unit called a polymer (poly: many; mer: unit). The structure of a polymer can be described as resembling numerous beads on a string, with the beads representing the individual units that are joined together.

The modern textile industry is unthinkable today without synthetic fibres. Man-made fibres like silk have always been greatly valued for its gloss and fineness. Man-made fibres are smooth. They can be distinguished by looking at a cross-section. Some synthetic fibres are listed below.
- rayon
- nylon
- polyester

(a) Shifting Cultivation: • Shifting cultivation is practiced in the thickly forested areas of Amazon basin, tropical Africa, parts of Southeast Asia and Northeast India. These are the areas of heavy rainfall and quick regeneration of vegetation. • A plot of land is cleared by felling the trees and burning them. The ashes are then mixed with the soil and crops like maize, yam, potatoes and cassava are grown. When soil loses its fertility, the land is abandoned and the cultivator moves to a new plot. • Shifting cultivation is also known as 'slash and burn' agriculture. • It is known by different names in the world – Jhuming in North-Eastern States of India, Milpa in Mexico, Roca in Brazil, Ladang in Malaysia and Ray in Vietnam.
(b) Nomadic Herding: • Nomadic herding is practiced in the semi-arid and arid regions of Sahara, Central Asia and some parts of India, like Rajasthan and Jammu and Kashmir. • In this type of farming, Herder does not grow any fodder but move from one place to another with their animals for fodder and water, along defined routes. • Sheep, Camel, Yak and Goats are most commonly reared. They provide milk, meat, wool and other products to the herders and their families.

The density of material shows the denseness of that material in a specific given area. A material’s density is defined as its mass per unit volume. Density is essentially a measurement of how tightly matter is packed together. It is a unique physical property for a particular object. The principle of density was discovered by the Greek scientist Archimedes. It is easy to calculate density if you know the formula and understand its related units.
Examples
Iron, platinum, and lead are examples of dense materials. Many types of rock and minerals are examples of dense material. Materials that are dense are most likely to ‘feel’ heavy or hard. The opposite of dense is sparse and a few examples of sparse material are glass, bamboo, aluminum, and styrofoam.
In general, liquids are less dense than solids and gases are less dense than liquids. This is due to the fact that solids have densely packed particles, liquids are materials where particles can slide around one another, and gases have particles that are free to move all over the place.

Gravitational force is a weak force unless large masses are involved. The masses of humans are quite small and thus the magnitude of gravitational force is also very small and negligible as compared to that shown by Earth. Thus, gravitational force exists between two people sitting close by but it is negligible and cannot be felt.

The memories we make with our near and dear ones is everything.
Sharing the joy and helping in the time of need is what is called a family.
Sharing the joy of festivals together with friends and neighbours allows us to build strong relationships with them. By this we come to know about rituals of each other. We learn to cherish people no matter from where they belong. Celebrating festivals together is an opportunity to spread love among people.
One might not have celebrated Durga Pooja before, one might not have celebrated Lohri before, one might not have celebrated Holi before, one might not have celebrated Christmas before, one might not have celebrated Pongal before etc.
But, when people from different corners come together in a neighborhood then the people celebrates all the festivals with a great energy, enthusiasm, and love.
Spread happiness, be together, and cherish every single moment with your friends and family. Festivals are a good way of a starting a fresh so never think twice before sharing this happiness.
