The square root of 3.61 is |
|
Answer» Step-by-step explanation: Step 1: Divide the NUMBER (3.61) by 2 to get the first guess for the SQUARE root . First guess = 3.61/2 = 1.805. Step 2: Divide 3.61 by the previous result. d = 3.61/1.805 = 2. Average this value (d) with that of step 1: (2 + 1.805)/2 = 1.9025 (new guess). Error = new guess - previous value = 1.805 - 1.9025 = 0.0975. 0.0975 > 0.001. As error > ACCURACY, we repeat this step again. Step 3: Divide 3.61 by the previous result. d = 3.61/1.9025 = 1.8975032852. Average this value (d) with that of step 2: (1.8975032852 + 1.9025)/2 = 1.9000016426 (new guess). Error = new guess - previous value = 1.9025 - 1.9000016426 = 0.0024983574. 0.0024983574 > 0.001. As error > accuracy, we repeat this step again. Step 4: Divide 3.61 by the previous result. d = 3.61/1.9000016426 = 1.8999983574. Average this value (d) with that of step 3: (1.8999983574 + 1.9000016426)/2 = 1.9 (new guess). Error = new guess - previous value = 1.9000016426 - 1.9 = 0.0000016426. 0.0000016426 <= 0.001. As error <= accuracy, we stop the iterations and use 1.9 as the square root. So, we can say that the square root of 3.61 is 1.9 with an error smaller than 0.001 (in fact the error is 0.0000016426). this means that the first 5 DECIMAL PLACES are correct. Just to compare, the returned value by using the javascript function 'Math.sqrt(3.61)' is 1.9 |

Six bells ring at intervals of 2 4 6 8 10 and 12 seconds respectively.They started ringing simultaneously. How many times will they ring together in 30 min |
|
Answer» Answer: LCM of 2, 4, 6, 8 10 and 12 is 120. So, after each 120 seconds, they would toll together. Hence, in 30 minutes, they would toll 30*60 seconds / 120 seconds = 15 times But then the QUESTION says they commence tolling together. So, they basically ALSO toll at the "beginning" ("0" second). So, total tolls together = 15+1 = 16 please mark as brainliest. |

The length of a rectangle is twice its width. If perimeter of rectangle is 42 metres find, the area of the rectangle? |
|
Answer» Answer: The Area of the Rectangle is 98 m² Step-by-step explanation: Given : Length of the Rectangle = Twice it's Breadth (WIDTH) Perimeter of Rectangle = 42 m To Find : The Area of the Rectangle Solution : Consider the Breadth as x Consider the Length as 2X ★ Perimeter of Rectangle = 2(Length + Breadth) ⇒ 2(2x + x) = 42 ⇒ 4x + 2x = 42 ⇒ 6x = 42 ⇒ x = 42/6 ⇒ x = 7 ★ Value of 2x ⇒ 2 MULTIPLIED by 7 ⇒ 14 Length = 14 m Breadth = 7 m ★ Area of the Rectangle = Length Breadth ⇒ 14 × 7 ⇒ 98 ∴ The Area of the Rectangle is 98 m² |

Write the rules for building magic squares. |
|
Answer» Calculate the magic constant.[1] You can find this number by using a simple math formula, where n = the number of rows or columns in your magic square. So, for EXAMPLE, in a 3x3 magic square, n = 3. The magic constant = n[(n^2+1)/2]. So, in the example of the 3x3 square: sum = 3 * [(9 + 1) / 2] sum = 3 * (10 / 2) sum = 3 * (5) sum = 15 The magic constant for a 3x3 square is 15. All rows, columns, and diagonals must add up to this number. 2 Place the number 1 in the center box on the top row. This is always where you begin when your magic square has odd-numbered sides, regardless of how large or SMALL that number is. So, if you have a 3x3 square, place the number 1 in Box 2; in a 15x15 square, place the number 1 in Box 8. 3 Fill in the remaining numbers using an up-one, right-one pattern. You will always fill in the numbers sequentially (1, 2, 3, 4, etc.) by moving up one row, then one column to the right. You’ll notice immediately that in order to place the number 2, you’ll move above the top row, off the magic square. That’s okay — although you always work in this up-one, right-one manner, there are three exceptions that also have patterned, predictable rules: If the movement takes you to a “box” above the magic square’s top row, remain in that box’s column, but place the number in the bottom row of that column. If the movement takes you to a “box” to the right of the magic square’s right column, remain in that box’s row, but place the number in the furthest left column of that row. If the movement takes you to a box that is already occupied, go back to the last box that has been filled in, and place the next number directly below it. |

An ant has to crawl from point A to point B usingthe staircase shown:3m6mWhat is the total distance the ant will crawl?Justify your answer! |
|
Answer» Answer: 9m. Step-by-step EXPLANATION: The ant has to MOVE from point A to point B using the staircase. It is given that, the height of the staircase is of MEASURE 3m and the horizontal LENGTH of the staircase is of measure 6m. Hence, the ant from point A has to climb the height 3m FIRST and then has to move a horizontal distance of 6m. Therefore, the total distance the ant has to crawl is (3+6)m = 9m. (Answer) |

The sum of the digits of a two digit number is 7. If the number formed by reversing the digits isless than the original number by 27, find the original number. |
|
Answer» Answer: Step-by-step explanation: Suppose the two digit original number is 10x+y. (x is at tens place so multiple by 10 and y is at UNIT place so left as is, you may MULTIPLY it by 1 to get a clear picture but 1y is represented as y only) The sum of digits of original number is 7 →x+y = 7 —equation(1) If 27 is added to original number its digits are interchanged .So, 10x + y +27 =10Y+ x → 9x +27 = 9y → 9(x+3) = 9(y) → x+3 = y — equation(2) Substituting value of y from equation (2) in equation (1) x + x+3 = 7 2x + 3 = 7 2x =4 x= 2 Substituting x= 2 in equation (2) y= 5 So original number is 10 (2) + 5 i.e. 20 +5 → 25. In order to CHECK the answer.. 25 is original number and 52 is the number formed by interchanging the digits. 25 +27 = 52. |
