In a rational the denominator of a number is 9 more than its numerator . If the rational number is added with 5 then the sum is equal to 51/10 . Find the rational number |
|
Answer» Answer: 1/9 Step-by-step explanation: so denominator=x+9 x/x+9 + 5 = 51/10 =>x/x+9= 51/10 -5 =>x/x+9=51-50/10 =>10x = x+9 =>10x-x=9 =>9x=9 x= 1 hence, numerator= 1 denominator = 10 |

Find the smallest number by which 1100 must be multiplied so that the productbecomes a perfect square. Also, find the square root of the perfect square soobtained.By what smallest number must 180 be multiplied so that it becomes a perfectsquare? Also, find the square root of the number so obtained. |
|
Answer» Answer: 1100, 30.Step-by-step explanation: 1100 = 11 * 5 * 2. Here, every prime factor appears only once. Hence to make it a PERFECT SQUARE, it must be multiplied by 1100 (11 * 5 * 2) itself. It GIVES the square root as 1100. 180 = 3 * 3 * 2 * 2 * 5. Here, the only prime factor that doesn't form a PAIR is 5. hence, 180 must be multiplied by 5 to make it a perfect square. The square root thus obtained WOULD be 3 * 2 * 5 = 30. |

Prove that area of equilateral triangle is root 3 by 2 into side square |
|
Answer» Step-by-step explanation: Step 1: Since all the 3 sides of the triangle are same, Step 2: FIND the altitude of the △ABC. Draw a perpendicular from point A to base BC, AD ⊥ BC By using Pythagoras theorem In △ ADC h2 = AC2 - DC2 = a2 - (a2)2 [Because, DC = a2 ] = a2 - a24 h = 3√a2 Step 3: We know that, Area of a triangle = 12 * Base * HEIGHT = 12 * a * 3√a2 = 3√4a2 The area of a equilateral triangle = 3√4a2. |

A sum of Rs 800 is in denomination of Rs 10 and Rs 20. If the total number of notes are 50.Find the number of notes of each types. |
|
Answer» Step-by-step explanation: Let's call RS. 10 x and Rs. 20 y: x+y= 50 If we subtract y from both sides we get: x= 50-y It makes sense, right? If I take the Rs. 20 notes out of the total of 50 notes, then I am left with just the Rs. 10 notes. So REMEMBER this value of x, we will use it in the next equation: 10x+20y= 800 Now substitute for x: 10(50-y)+20y= 800 500-10y+20y= 800 Subtract -10y+20y on left and subtract 500 on both sides:
10y= 300 y= 30 You have 30 notes of 20 Rs. and: 50-30= 20 notes of 10 Rs. ------------------------ Proof: 30(20)= 600 20(10)= 200 _ _ _ _ ---- Total..: 800 We have the correct answer |
