The age of Ashwini's mother is 5years more Than twice of Ashwini's Age. After 10 years, her mother's age will be 08 years less than thrice her age. Find their present age |
Answer» Answers✩ Present AGE of Ashiwini = 23 YEARS . ✩ Present age of Ashiwini's mother = 51 years. SOLUTIONLet us Assume that the Present age of Ashiwini as 'x' years. Case :- 1 The age of Ashwini's mother is 5years more Than twice of Ashwini's Age. The Present age of Ashwini's mother = 2x + 5 Case :- 2 After 10 years, her mother's age will be 08 years LESS than thrice her age. Age of Ashwini's mother after 10 years = 3X - 8 We have found in (1) that the present age of Ashwini's mother is 2x + 5 , so after 10 years it will be 2x + 5 + 10 = 2x + 15 Now, Let us equate Equations (2) and (3) 2x + 15 = 3x - 8 3x - 2x = 15 + 8 x = 23 years Present age of Ashiwini (x) = 23 years. Now , we can FIND the present age of Ashwini's mother by substituting 'x' as 23 in Equation (1) . The Present age of Ashwini's mother = 2 × 23 + 5 The Present age of Ashwini's mother = 46 + 5 The Present age of Ashwini's mother = 51 years.

|
Answer» Answer: Answer REF.Image The COST of gravelling them at Rs. 1.20 per square meter = Rs . 1560 To find the area of roads : It is given that a rectangular LAWN 80 m × 60 m has two roads each 10 m WIDE running in the middle of it. Dimension of two roads are 80×10 and 60×10 Area of two roads = 80×10+60×10−10×10 =800+600−100 = 1300 sq. meter To find the cost for gravelling It is given that The cost of gravelling the at Rs. 1.20 per sq. meter. Therefore total cost = total area × cost per sq. meter =1300×1.20 =Rs.1560 ∴ The cost of gravelling them at Rs. 1.20 per sq. meter = Rs. 1560 solution |

In a circle of diameter 42cm,if an arc subtends an angle of 60˚ at the centre where π = 22/7, then what will be the length of arc. |
|
Answer» Step-by-step explanation: Given:-In a circle of diameter 42cm,if an arc subtends an angle of 60˚ at the centre where π = 22/7. To find:-what will be the LENGTH of arc. Solution:-Diameter of a circle (d)=42 CM =>RADIUS of the circle (r)=Diameter/2 =>r=42/2=21 cm An angle subtends by the arc =(x)=60° Length of the arc (l)=x°×2πr/360° units =>60°×2×(22/7)×21/360° =>(60°×2×22×21)/(7×360°) =>2×22×3/6 =>22 Length=22 cm Answer:-Length of the arc for the given PROBLEM is 22 cm Used formula:-If the radius of the circle is" r "units and the angle subtended by the arc in the circle is x° then the length of the arc is (x°×2πr)/360 π=22/7 |

Simplify 15(y-4)+2(y-9)+(y+6)=0 Can anyone tell the answer |
|
Answer» 15(y-4)+2(y-9)+(y+6)=0 Step 1: first we will expanding the terms ➠15×y-4×15+2×y-9×2+y+6=0 ➠15y-60+2y-18+y+6=0 Now, terms are unarranged so ,we first arrange the term by placing like terms together means terms of same Variable together. ➠15y+2y+y-60-18+6=0 Solving CONSTANT term Concept: plus minus =minus minus minus =plus (but we PUT sign of -) ➠15y+2y+y -78+6=0 ➠15y+2y+y -72=0 solving first term or Variable terms ➠18y-72=0 -72 is negative on the left side when we shifts it towards right side it's sign GETS changed. ➠18y=72 we KNOW 72 comes up in multiples of 18 ➠y=72÷18=4 y=4Check15(y-4)+2(y-9)+(y+6)=0 =>15(4-4)+2(4-9)+(4+6) =>15×0+2×-5+10 =>0-10+10=0+0=0 |
