What is the Mixed Fraction of 531/60 |
|
Answer» Step-by-step explanation: To start with, the number above the LINE (531) in a fraction is called a numerator and the number below the line (60) is called the denominator.So what we want to do here is to simplify the numerator and denominator in 531/60 to their lowest POSSIBLE values, while keeping the actual fraction the same.To do this, we use something called the greatest common factor. It's also known as the greatest common divisor and put simply, it's the HIGHEST number that divides exactly into two or more numbers.In our case with 531/60, the greatest common factor is 3. Once we have this, we can divide both the numerator and the denominator by it, and voila, the fraction is simplified:531/3 = 17760/3 = 201772053160=17720Hope its help.. |

Find the volume of the sphere " x² + y² + z² = n² " . Either Using Simple Triple Integrals or Using Dirichlet Theorem for Triple Integrals ! |
|
Answer» Answer: Now that we know how to integrate over a two-dimensional REGION we need to move on to integrating over a three-dimensional region. We used a double INTEGRAL to integrate over a two-dimensional region and so it shouldn’t be too surprising that we’ll use a triple integral to integrate over a three dimensional region. The notation for the GENERAL triple integrals is, ∭ E f ( , y , z ) d V ∭Ef(x,y,z)dV Let’s start simple by integrating over the box, B = [ a , b ] × [ c , d ] × [ r , s ] B=[a,b]×[c,d]×[r,s] Note that when using this notation we list the x x ’s first, the y y ’s second and the z z ’s third. The triple integral in this case is, ∭ B f ( x , y , z ) d V = ∫ s r ∫ d c ∫ b a f ( x , y , z ) d x d y d z ∭Bf(x,y,z)dV=∫rs∫cd∫abf(x,y,z)dxdydz Note that we integrated with respect to x x first, then y y , and finally z z here, but in fact there is no reason to the integrals in this order. There are 6 DIFFERENT possible orders to do the integral in and which order you do the integral in will depend upon the function and the order that you feel will be the easiest. We will get the same answer regardless of the order however. Let’s do a quick example of this type of triple integrals. Step-by-step explanation: mark me as brain list |

The product of two rational numbers is the reciprocal of .One of the number is thenfind the other number. |
|
Answer» CORRECT option is C − 3 2
Lets say numbers are a and b So, the product of numbers is a×b Product of number is given =− 81 28
ONE number is 27 14
say a= 27 14
⇒ 27 14 ×b=− 81 28
⇒b=− 81 28 × 14 27
⇒b=− 3 2 |

Maths Lab Activity 55 Alm: To understand square numbers Materials required: a. A peg board b. Pegs of different colours Method: Take a peg board and pegs to make squares of different sizes. A single peg will be considered as a square of side 1 unit. Make seven squares (of sides 1, 2, 3, ..., 7 units) on the peg board and name them as S, S, ..., S., respectively. You will observe the following. *Number of pegs used in first square, S = 1 = 1 S1 Number of pegs used in second square, S. = 4 = 2² S2 Number of pegs used in third square, S = 9 = 3 S3 S4 Number of pegs used in fourth square, S = 16 = 4² Number of pegs used in fifth square, S = 25 = 5 Number of pegs used in sixth square, S = 36 = 6 Number of pegs used in seventh square, S = 49=7 The numbers 1.4.9.16, 25, 36, 49 are called square numbers since these number of pegs can be arranged to make squares. Continuing S7 in the same way, you can get the next square numbers as 8 = 64, 9 = 81, 10 = 100. 11% = 121 and so on. S6 |

A triangle and a parallelogram have the same base and same area. If the sides of the triangle are 26 cm, 28 cm and 30 cm, and the parallelogram stands on the base 28 cm, find the height of the parallelogram. |
|
Answer» Answer: For ∆ABE, a = 30 cm, b = 26 cm, c = 28 cm Semi Perimeter: (s) = Perimeter/2 s = (a + b + c)/2 = (30 + 26 + 28)/2 = 84/2 = 42 cm By USING Heron’s formula, Area of a ΔABE = √s(s - a)(s - b)(s - c) = √42(42 - 30)(42 - 28)(42 - 26) = √42 × 12 × 14 × 16 = 336 cm2 Area of parallelogram ABCD = Area of ΔABE (given) Base × Height = 336 cm2 28 cm × Height = 336 cm2 On rearranging, we get Height = 336/28 cm = 12 cm Thus, height of the parallelogram is 12 cm. |
