QUESTION=Three consecutive integers add up to 51. what are these integersMath for class 8th linear equation . ex 2.2 Que 6 Write correct answers only ..

Answer»

Answer:

\huge\purple {\mathfrak{Bonjour Mate!}}

These three INTEGERS SUM up to 51; THEREFORE set up the FOLLOWING equation and solve: X+(x+1)+(x+2)=51. 3x+3=51. 3x=48. x=16. Therefore, the first integer is 16 and the next two integers are 17 and 18. The largest one is 18 and this is the answer.

8.

Please solve this !!​

Answer»

ANSWER:

Let OC= CD= DE= EA = x

SINCE OA = 2

OA= OC + CD + DE+ EA

2 = x+x+x+x

2= 4x

2/4=x

1/2=x

THEREFORE the rational no reprecented by

C =1/2

D = 1/2+1/2

= 1

E = 1+1/2

= 3/2

Let OF = FB =y

since OB = -1

OB = OF + FB

-1 =y+y

-1 =2y

-1/2 =y

THEREFORE the rational no F = -1/2

.4. Find the area of a right triangle whose base is 1.2 m and hypotenuse 3.7 m.​

Answer»

Answer:

2.1 m^2

Step-by-step explanation:

 Here,

    Base of that TRIANGLE is 1.2 m and hypotenuse is of length 3.7 m.

As it's a right ANGLED triangle Pythagoras theorem can be applied.

   Using Pythagoras theorem:

⇒ base^2 + height^2 = hypotenuse^2

⇒ ( 1.2 m )^2 + height^2 = ( 3.7 m )^2

⇒ 1.44 m^2 + height^2 = 13.69 m^2

⇒ height^2 = 13.69 m^2 - 1.44 m^2

⇒ height^2 = 12.25 m^2

⇒ height^2 = ( 3.5  m )^2

⇒ height = 3.5 m

    We KNOW area of right angled triangles is given by half of the product of its height and base.

Area of this triangle =  1 / 2  * 3.5 * 1.2  m^2

       = 3.5 * 0.6  m^2

       = 2.1 m^2

Utilize your time at home during lockdown, SPEND time in learning new thing

दैनिक भास्कर

Apr 07, 2020, 10:13 AM IST

लाइफस्टाइल डेस्क. सारी दुनिया एक बड़ी समस्या से जूझ रही है, ऐसे में देश में लॉकडाउन है। सभी को घर के भीतर ही रहने की सलाह दी जा रही है। जो नौकरीपेशा हैं या अक्सर काम के सिलसिले में बाहर रहते हैं, उन्हें सारे दिन घर पर रहना थोड़ा मुश्किल लग सकता है। पर चिंता न करें, समय का बेहतर सदुपयोग करने और उसे मजे से गुजारने के लिए हम कुछ उपाय लेकर आए हैं।

सोचिए जरा

नौकरी के दौरान हम सब किस तरह छुट्‌टी का इंतजार किया करते थे। आज जब घर रहने की जरूरत है तो ऊब होने लगी है। पहले सोचते थे छुट्‌टी मिल जाए तो घर को सजाएंगे, नए-नए प्रकार के भोजन बनाएंगे या दोस्तों से बतियाएंगे। पर आज जब ये सब करने का मौक़ा है तो समय को यूं ही जाया किए जा रहे हैं। इसलिए सोचिए कि क्या कुछ किया जा सकता है।

अभिनय दिखाएं

एक्टिंग, मिमिक्री या गम्भीर थिएटर करने का मन सबका होता है लेकिन वक्त नहीं मिलता। अब मौका मिला है, तो वर्चुअल थिएटर का आयोजन कीजिए और कला को निखारिए।

लेखन आजमाइए

इस समय छोटा-मोटा कुछ लिखने का समय मिल सकता है। और अगर आपके मित्र समूह में आपके जैसी रुचि अन्य लोगों में भी है, तो एकाध शब्द या विषय आपस में बांट लें और उस पर कुछ लिखकर एक-दूसरे से साझा करें। नए-नए शब्दों की जानकारी बांटकर अपना शब्दज्ञान भी बढ़ा सकते हैं।

किस्सों की साझेदारी

कभी फुर्सत मिलेगी तो किताब पढ़ेंगे और दोस्तों, परिजनों को अच्छी कहानियां सुनाएंगे- अगर आपने भी ऐसा सोचा था, तो उसे विचार को यथार्थ में उतारने का समय अभी है। चाहें तो बुक क्लब बनाएं, वीडियो पर रीडिंग सेशन रखें या फिर कहानियां वॉट्सएप पर साझा करें, मर्जी आपकी है।

वीडियो कॉल से जुड़ें

जाहिर है, पार्टी, मौज-मस्ती, घूमने-फिरने की कमी खल रही है तो उन्हें वीडियो कॉल करें और एक-साथ जुड़े। इस दौरान मिलकर अंताक्षरी खेल सकते हैं या कॉलिंग करते हुए नई-नई रेसिपीज़ बना सकते हैं। इससे समय भी कटेगा और खालीपन भी महसूस नहीं होगा। और भई, वीडियो कॉलिंग तो है ही ना। एक समय तय कीजिए और मिलकर फोन पर गपशप कीजिए।

व्यायाम न भूलें

ये समय रोग प्रतिरोधक क्षमता बढ़ाने का है। ऐसे में बहुत ज़रूरी है कि घर के सभी सदस्य व्यायाम-योग को दिनचर्या में शामिल करें। यदि योग नहीं करना चाहते तो रस्सी कूद सकते हैं या नृत्य कर सकते हैं। ये सभी आपको चुस्त-दुरुस्त रखने में कारगर हैं। इसलिए दिन का कुछ समय शरीर को स्वस्थ और सेहतमंद बनाने के लिए दें।

नया सीखें

यदि मन में डांस, पेंटिंग जैसा कुछ नया सीखने की इच्छा है, तो ऑनलाइन वीडियोज से इस इच्छा को पूरा किया जा सकता है। दिन का कुछ समय नया सीखने में लगाएं। इसके अलावा नई-नई रेसिपीज बनाना पसंद है तो उसका वीडियो बनाकर दोस्तों, करीबियों के साथ साझा कर सकते हैं।

♥️Hello FriendS! ♥️_________________________________________Q.1 Answer the questions in Breif :- a. A Plastic Cube is Released in water, will it sink or come to the Surface of water? b.) Why do the load carrying heavy Vehicles have Large numbers of wheels? c.) How much pressure do we carry on our heads ? why don't we feel it ? ​

Answer»

\Large{ \sf{{\ddag\: \: \underline{ \underline{ \red{Question \: and \: Answers...}}}}}}

━━━━━━━━━━━━━━━━━━━━

Q.1 Answer the questions in Breif :-

a. A Plastic Cube is Released in water, will it sink or come to the Surface of water?

Ans- It is decided by a CONCEPT of Buoyancy that whether a SUBSTANCE floats or SINKS in water. Buoyancy or upthurst means the upward force exerted by the liquid on any particular object immersed in it. It depends upon the density of the body.

  • A body with less density than water, or relative density less than 1 will float on water due to greater buoyant force.
  • A body with greater density will sink in water.
  • And a body will density equal density as of water will half submerged or partially submerged (i.e half in water, half in air).

The plastic is the light weight substance and have density less than water, thus it will float on water. This phenomenon has become the biggest reason for ocenic water pollution.

﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏

b.) Why do the load carrying heavy Vehicles have Large numbers of wheels?

Ans- The load carrying heavy vehicles have a large weight thus, they exert a high pressure to the ground. This can even break the ROADS and can cause accident, to avoid this ,they have large no. of wheels which increase the surface AREA in contact with the ground, and the weight will be equally distributed and hence reducing pressure. It is because the pressure is inversely proportional to area of contact. This can be better understood by the formula for pressure i.e.

\Large{ \ast{ \boxed{ \purple{ \sf{Pressure =  \frac{Force}{Area}}}}}}

Thus, the load carrying heavy vehicles are provided with large no. of wheels.

﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏

c.) How much pressure do we carry on our heads ? why don't we feel it ?

Ans- The atmosphere is around us i.e. the layer of air. As we know that gases also exerts pressure, hence we are carrying the entire atmospheric pressure of 1 atm i.e. 10^5 pascals. But, isn't it strange, that we are not able to feel anything? It is because of the blood that is flowing inside our body also exerts the same pressure in an outward direction and the atmosphere in the inward direction. Thus these pressure balances each other and have no effect on our body.

PLeAse AnSwEr ThiS QuEsTiON ❣️❣️​

Answer»

Answer:

[Figure in the attachment]

Given –

  • A point above the lake is Q.
  • The DISTANCE between the point P and Q is 200 m.
  • ANGLE of elevation from the point Q to the cloud is 30°.
  • The angle of depression from the point Q to the reflection of the cloud in the lake is 60°.

To Find –

  • Height of the cloud.

Solution –

We know that the length PQ is 200m. Hence, AB = 200 m.

Now, height of cloud = AB + BC.

We know the length of AB, We need to find BC.

In ∆ QBC,

tan ∅ = Perpendicular/Base

Hence, tan 30° = BC/QB.

➸ tan 30° = X/QB

[Assumed BC as x]

➸ 1/√3 = x/QB

➸ QB = √3 x ....k1)

In ∆ QBD,

tan ∅ = Perpendicular/Base

Hence, tan 60° = BD/QB

➸ √3 = (200 + AD)/QB

➸QB√3 = 200 + AD

➸ QB = (200 + AD)/√3 ....(2)

Equating equation 1 and 2,

➸ QB = √3 x = (200 + AD)/√3

➸ 3 x = 200 + AD

[AD = 200 + x]

➸ 3 x = 200 + 200 + x

➸ 3 x = 400 + x

➸ 3 x - x = 400

➸ 2 x = 400

➸ x = 400/2

➸ x = 200

Hence, Height of cloud = 200 + x = 200 + 200 = 400 m.
