Solve the following equation in pair of linear equation by elimination method5x-8y=11 & -10x+6y=-22 |
|
Answer» Thanks for give the answer First multiply eq 1 by 10 i.e 50x - 80y = 110 And eq2 by 5 i.e -50x + 30y =-110 Now 50x - 80y = 110-50x+30y = -110------------------0x -50y = 0 --------------------50y = 0Y =0 For x put the value of y in eq -150x-80×0 = 11050x=110X=110/50X= 2.2 |

Solve the following systems of equations 11x+15x+23=07x-2y-20 =0 |
| Answer» 11x + 15y = -23 ---- (1) ////// 7x - 2y = 20 ---- (2). Take equation (2). Thus, x = 20 + 2y / 7// ---- (A). Equating (A) to (1), we get :- 11 (20 + 2y / 7) + 15y = -23 => 220 + 22y / 7 + 15y = -23 => 220 + 22y + 105y = -161 => 127y = -161 - 220 => 127y = -381 => y = -3// Therefore, x = 20 + 2y / 7 = 20 - 6 / 7 = 14 / 7 = 2// | |

Use euclid s algorithm to find the HCF of 4052 and 12576 |
| Answer» According to Euclid’s Division Lemma if we have two positive integers a and b, then there exist unique integers q and r which satisfies the condition a = bq + r where 0 ≤ r ≤ b.HCF is the largest number which exactly divides two or more positive integers.Since 12576 > 405212576 = (4052 × 3) + 420420 is a reminder which is not equal to zero (420 ≠ 0).4052 = (420 × 9) + 272271 is a reminder which is not equal to zero (272 ≠ 0).Now consider the new divisor 272 and the new remainder 148.272 = (148 × 1) + 124Now consider the new divisor 148 and the new remainder 124.148 = (124 × 1) + 24Now consider the new divisor 124 and the new remainder 24.124 = (24 × 5) + 4Now consider the new divisor 24 and the new remainder 4.24 = (4 × 6) + 0Reminder = 0Divisor = 4HCF of 12576 and 4052 = 4. | |

How many types of blood in our body and name them? |
| Answer» There are generally two types of blood flowing through the human body namely :- 1) OXYGENATED BLOOD = Blood which is abundant in oxygen. This blood enters the Left atrium of the heart and is then passed on to Left Ventricle from where it is pumped to other cells.2) DEOXYGENATED BLOOD = Blood abundant in carbon dioxide. Enters right atrium then into right ventricle and finally pumped to lungs for purification. | |

If tan A =3/4 show that sin A cos A = 12/25 |
| Answer» tan A = 3/4 ==> sin A/cos A = 3/4. Hypotenuse = √(3)^2 + (4)^2 = √9 + 16 = √25 = 5 units. Therefore, sin A * cos A = 3/5 * 4/5 = 12/25// Hence proved. | |

What is a composite number and a prime number? (2 marks) |
|
Answer» Composite number is a number who have multiple more than one for example 4,6,8 while the numbers which have only the factor of 1 and the number itself are known as prime number for example 2,3,7,23 Please like ,share and subscribe my video on YouTube.https://youtu.be/crGyWC-oxjc Prime no. r those numbers that hv only 2 factor that is one and the number itself.e.g the number 2 is a prime number because it have only 2 factor that is 1 and 2 .Also let 3 is a prime number because it has only 2 factor that is one and the number itself.The factor of three are 1,3.Now,We can say that any number that have only two factor is known as prime number.And composite number are just opposite of prime number.*Composite number are the number that have more than two factor.means any number which have 2+ factor,those number will be known as composite number.E.g 8 is a composite number because it is a factor of 1,2,4,8.Now it can be said that 8 is a composite number as it have more than 2 factor.Thanks,hope u understand. prime no. - prime numbers are those numbers which have ony 2 factors , first factor is 1 and the other factore is the number itself .Composite no. - all the numbers having factors more than 2 ( i.e. 1 and the number its self ) - smallest prime number is 2 - smallest composite number is 4 - 1 is neither prime nor composite - many times question comes that find hcf of smallest prime and smallest composite number than people find HCF of 1 and 4 because they think 1 is smallest prime number . - Always remember 1 is neither prime nor composite. - I am your senior 2020 batch , if you want my hand written notes for every subject , u can mail me at.

Answer» Surface area and volume are calculated for any three-dimensional geometrical shape. The surface area of any given object is the area or region occupied by the surface of the object. Whereas volume is the amount of space available in an object. Cube => TSA = 6a^2 , CSA = 4a^2 , Volume = a^3. Cuboid => TSA = 2 (lb + bh + lh) , CSA = 2 (l + b)h , Volume = lbh. Cylinder => TSA = 2πr (r + h) , CSA = 2πrh , Volume = πr^2h. Cone => TSA = πr (r + l) , CSA = πrl , Volume = 1/3 πr^2h. Sphere => TSA = CSA = 4πr^2 , Volume = 4/3 πr^3. Hemisphere => TSA = 3πr^2 , CSA = 2πr^2 , Volume = 2/3 πr^3. |
