Reema will lose 15%, if he sells a cow for ₹10200. For how much should he sell it to gain 15 %? |
|
Answer» Answer: Step-by-step EXPLANATION: Let’s assume X as the Price of the COW. To make the loss of 15%, she should sell the cow at the price, 15% lesser than it’s original price. so price she SOLD the cow is ((100–15)/100)*X = 10200 ==> 85/100*X=10200 Therefore, X=10200*100/85= Rs. 12000/-( actual price) Now, To make 15% profit on its original price she should sell the cow at a 15% higher rate therefore, S.P= 12000*115/100 ==>Rs. 13800/- (ANS)(price at which he will get 15% profit) |

Find the area of triangle whode vertices are (4,3) (1,4) and (2,3) |
|
Answer» Step-by-step explanation: see here i will not give you the answer right now as I currently don't have a pen and but I am going to tell you the way to do it. See starting with the Ques first check whether it is a right angled triangle or not. this you can do by slope form i.e., find the slope between the three given points one by one ( slope=(y2-y1)/(x2-x1)). if any TWO slope comes in the form as: M1*M2=-1. i.e. product of any two slope =-1 then it is a right angled triangle Then if it is a right angled triangle then by distance formula find the length of each side then use area=1/2*BASE* height. Then if it is not a right angled triangle then use herons formula. Herons formula={√s(s-a)(s-b)(s-c)} remember all the things are in square root. Now s=(a+b+c)/2 where, a,b,c are the length of the sides of the triangle. Now if you know DETERMINANTS then it is going to be a quite easy task . I will tell u that way also (do only if know just how to find the value of the determinants). area=1/2* take 3*3 determinant then take first row of determinants as 1 and then FILL the other two rows with the coordinate given exactly in the same order as it is. and just solve the determinants which is a one LINE Ques. and you will get the ans. |

the ratio od adjacent angles of a parallelogram is 4x5 find all the angles of the parallelogram....pls tell fast urgent !! |
|
Answer» Answer: since adjacent angles in a PARALLELOGRAM are co-interior therefore 4x + 5x = 180 9x = 180 x = 180/9 = 20 angles = 4x=80 and 5x=100 since opposite angles of a parallelogram are EQUAL therefore all the angles are:- 80, 100, 80, 100 |

Name an object that is different from a ball based on its properties. Write its properties as well |
|
Answer» Step-by-step explanation: Objects around us are all kinds of objects and THUS identifying them is important. Doors, fans, ball, book, PEN, pencil, table are few objects which are around us. All these differ from one another by some properties. Every object we USE is made to fulfil some purpose for us. Usage of each object depends on their properties and purpose. For example, a ball is an object to fulfil the need of a child playing, an AC to provide coolness. Hence, we can identify the objects based on their shape, size, colour and texture. Object Around Us We look around and find a different kind of objects around us like fan, tube-light, pens, pencils, computes, papers, a chair, stone and many more. All these have properties of their own and it is important to know these properties. Furthermore, we can classify objects into these properties. We look around and identify an object based on the colour, shape, size, texture and lustre of an object, accordingly cluster them into a similar objective cluster. Similar objective clusters are the cluster of objects having same property and hence we can classify them as one cluster. Object Identification Object IdentificationColour: An object having same colour are classified into one cluster. Colour and appearance are used to classify object cluster. For example, a particular colour depicting a THING, in other words, red colour depicting danger. Texture: Every object posses a different kind of texture. The object cluster is made with the surface and feel of the material. For example, the surface of the material, certainly like Sand-paper and Rock Shape: An object of the same shape are classified into one group. Objects having the same shape are therefore classified into one object cluster. For example, objects having a similar shape, most likely to be a ball and globe. Lustre: An object with shine are classified into one cluster. All the objects having shine, as a result, classified into one cluster. For example, Gold and Silver. An object is classified on these properties, as a result, these properties help in clustering the objects. We now know the property of an object and henceforth can classify then easily. In conclusion object and it’s properties are important. Identify objects using physical properties such as size, shape, color, texture, smell, and weight. COMPARE and sort objects using similar or different physical properties such as size, shape, color, texture, smell, and weight. Use simple tools, such as balances, to explore the weight of objects. |
