Solve the following equation and verify the answer (a) 7x/5=10

Answer»

GIVEN: The term 7X/5=10

To find: SOLVE the following EQUATION and verify the answer.

Solution:

  • Now we have given the term 7x / 5 = 10.
  • Now solving this term, we get:

                 7x / 5 = 10

                 7x = 50

                 x = 50/7

  • Now putting the value of x in ORIGINAL equation, we get:

                 7(50/7) / 5 = 10

                 7(50/7) = 50

                 50 = 50

                 LHS = RHS.....hence verified.

Answer:

            So the value of x is 50/7.

x=2y=3zx=2y=3z .... (1)

It is ALSO given that

Batting average of batsman in his 27 innings is 47.07 . in his next inning he scored some runs such that his average is increased by 3 . find runs scored by him in his 28th innings.

Answer»

Step-by-step explanation:

GIVEN Batting AVERAGE of batsman in his 27 innings is 47.07 . in his next inning he scored some RUNS such that his average is increased by 3,  find runs scored by him in his 28th innings.

  • Total runs of a batsman in 27 innings will be 27 x 47.07
  •                                                                           = 1270.89
  • Now in 28th innings his average will be 47.07 + 3
  •                                                                  = 50.07
  • Total runs scored in 28 innings will be 28 x 50.07
  •                                                                    = 1401.96
  • Therefore runs scored by him in his 28th innings will be                                    1401.96 – 1270.89
  •  = 131.07

Zach keeps his pet chameleon Pinky in a terrarium with the dimensions shown below. There are 333 inches of sand in the bottom of the terrarium. Zach gets a new terrarium for Pinky that is larger. The base of the new terrarium is 101010 by 242424 inches. Zach moved the existing sand to the new terrarium. How deep will the sand be in the new terrarium?

Answer»

Given :  Zach keeps his PET chameleon PINKY in a terrarium with the dimensions 20 * 8 inch of base . 3 inches of sand in the bottom of the terrarium .  new terrarium is 10 by 24  inches

To find :  How deep will the sand be in the new terrarium

Solution:

EXISTING Terrarium Base = 20 * 8  

Sand Height = 3 inch

Volume of Sand in Terrarium

= 20 * 8 * 3

= 480  inch³

New Terrarium Base = 10 * 24  

Let say Height of Sand in New terrarium = h inches

Volume of Sand = 10 * 24 * h

= 240 h  inch³

240 h = 480

=> h  = 2

Sand will be 2 inch deep in  new terrarium

घड्याळ या शब्दावर मत मांडा।

Answer»

\huge\star\mathfrak\red{{Answer:-}}

घड्याळ

वेळ अमूल्य आहे, वेळ म्हणजेच पैसा; असे आपण खूप वेळा ऐकलं आहे. आपण ठराविक वेळेत शाळेत येतो, ठराविक वेळेचे लेक्चर्स असतात. शनिवारी तर सकाळची शाळा असते, नेहमीपेक्षा लवकर उठावे लागते, नाही का? कल्पना करा जर घड्याळ नसतेच तर, किंवा घड्याळ बंद पडले तर. याच विषयावर मी आज तुमच्या समोर बोलणार आहे.

घड्याळ असण्याचे फायदे

खरंच घड्याळासाठी आपण की आपल्यासाठी घड्याळ हेच कळत नाही इतके आपले जीवन घड्याळाशी बांधले गेले आहे. आपल्या या मनुष्यजन्मात घड्याळाला अनन्यसाधारण महत्व आहे. माणूस जन्मल्यापासून ते मरेपर्यंत त्याचे घड्याळाशी नाते घट्ट असते. आपले जीवन हे घड्याळाच्या काट्याबरोबर बांधलेले असते.

विद्यार्थीदशेत घड्याळ पाहून अभ्यास, खेळ यांची दैनंदिनी बनवली जाते. घड्याळ पाहून शाळेत येणे, जाणे, नाष्टा करणे, एवढेच नव्हे तर जेवण सुद्धा आपण या घड्याळाच्या काट्यावर करतो. म्हणजेच दैनंदिन जीवनात सकाळी उठल्यापासून ते झोपेपर्यंत सर्व कामे ही घड्याळावर अवलंबून असतात.

घड्याळाचे काम काय असते? वेळ दाखवणे. किती वाजले, किती तास, मिनिटे झाली. या साध्याश्या यंत्रामुळे आपलं दैनंदिन जीवन सुखकर होते. साल १९२७ मध्ये वॉरेन मार्रीसोन आणि ज.व. हॉर्टन यांनी बेल टेलेफोन लॅबोरेटरी मध्ये क्वार्ट्ज (QUARTZ) घड्याळाचा शोध लावला. क्वार्ट्ज हा एक क्रिस्टल ऑसीलेटर किंवा आंदोलक आहे, जे अतिशय तंतोतंत वारंवारितेसह सिग्नल तयार करते, ज्यामुळे क्वार्ट्ज ची घड्याळे यांत्रिक घड्याळांपेक्षा अचूक सिग्नल्स देतात. क्वार्ट्ज ला सिलिकॉन डायओकसाइड सुद्धा म्हटले जाते आणि हे एक पीएझोइलेक्ट्रिक मटेरियल आहे. या तंत्राने माणसाचे जीवन सुखकर बनवले.

Square is divided into four parts 20 cm^2, 16cm^2, 32cm^2 find the fourth part​

Answer»

Answer:

fourth part is 13 cm^2 or 32 cm^2

Step-by-step explanation:

we know that if length of SIDE of square is 'a'

then its area is given by a square..

means area must be a PERFECT square.

area of square is SUM of all the areas in the figure..

that is 20 + 16 + 32 + x = 68 + x

the nearest square is 81.. so to GET 81 x must be 13.. but if u see the figure it appears that fourth part is bigger than 20 so I must go to next square number that is 100 then u will get x to 32...

निसर्ग माझा मित्र विचार स्पष्ट करा।

Answer»

\huge\boxed{\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R:-}}}}}

निसर्ग माझा मित्र

पृथ्वीवर जीवन बहरण्याचे एकमेव कारण आहे ते म्हणजे इथले वातावरण आणि निसर्ग. या वातावरणाशीवाय, निसर्गाशिवाय कुठल्याही ग्रहावरती जीवन बहरू शकत नाही. या सौरमंडलात आपण अशा अमूल्य ठिकाणी राहत आहोत, आपलं पूर्ण अस्तित्वच या निसर्गाने मांडले आहे.

जेव्हा एखादा नवीन ग्रह बनतो तो लाव्ह्याचा एक जळता गोळा मात्र असतो, हा गोळा अवकाशात लाखो वर्ष फिरत राहतो. तो हळूहळू थंड व्हायला सुरुवात होते पण या प्रक्रियेत सुद्धा लाखो वर्षं निघून जातात.

अशा लाखो वर्षांच्या मेहनतीनंतर ग्रह जेव्हा पुरेसा थंड होतो तेव्हा जीवनचक्राचे पहिले पाऊल ग्रहावरती पडते, ते म्हणजे वातावरण बनण्याची सुरुवात. कुठलही ग्रहावरती वातावरण बनण्यासाठी कार्बोन डाय ऑक्साइड सारख्या ग्रीन हाऊस वायूंची गरज असते. तिथल्या जमिनीवरच्या रासायनिक प्रक्रियेतून, ज्वालामुखी मधुन हे ग्रीनहाउस वायू बाहेर पडतात आणि हळूहळू वातावरण बनायला मदत करतात.

लाखो वर्षांच्या या प्रक्रियेनंतर तो ग्रह संतुलित होतो, जर तिथे पाण्याचे अस्तित्व निर्माण झाले तर जीवनाची दुसरे पाऊल उचलले जाते. जिवाणूंच्या रूपामध्ये जीवनचक्र आपले काम चालू करते. परत एकदा लाखो वर्षांच्या उत्क्रांती नंतर छोटे छोटे प्राणी, पक्षी, झाडेझुडपे, सजीव रूप घेऊ लागतात. हळूहळू त्या ग्रहावरती निसर्ग आपले अस्तित्व प्रस्थपित करायला सुरुवात करतो आणि मग हा निसर्ग प्राणी, पक्षी, झाडे, झुडपे, कीटक वाढवतो. आणि मग तिथून जीवनचक्राचा पुढचा लाखो वर्षांचा प्रवास सुरू होतो.
