A box has 7 white balls, 9 red balls,5 green balls.At least how many balls you have to take to ensure that you have 3 balls of the same colour????plz answer urgently needed!!! |
Answer» ||✪✪ CORRECT QUESTION ✪✪||A box has 7 white balls, 9 red balls,5 green balls.At least how many balls you have to take to ensure that you have 3 balls of the Each COLOUR ???? || ✰✰ ANSWER ✰✰ ||We have 7 white balls, 9 red balls,5 green balls and we need Balls of Each color. As we can see that, Green balls are lowest in numbers so, we can say that, they are HARDEST to pick from box.... Let us suppose we pick first 7 balls and they all are of white colors, than , we pick 9 balls and we get all of them of red color . But we need balls of each color . So, now , we have to Pick one more BALL and that will be of color green. and Hence, we have balls of Each color. So, we can say that :- ➺ Least number of balls picked = 7 + 9 + 1 = 17 . ( To get balls of Each color . 17 is correct answer._____________________________we can Remember this directly now also, :- ☛ To pick balls of Each color = ( sum of Two largest Numbers ) + 1 . ☞ ( 7 + 9 ) + 1 ☞ 17 (Ans)._______________If you want to Pick 3 balls of each color now, ☞ (7+9) + 3 ☞ 19 . we have to pick atleast 19 balls if we want 3 balls of Each color . |

Numbers which end in 0, 1,4,5 or 6 are always perfect squares.Thesaures of numharc andinni 1 un |
|
Answer» Answer: Step-by-step explanation: Check whether the number can be made perfect SQUARE after adding 1 Given an integer N, the task is to check whether N the given number can be made a perfect square after adding 1 to it. Examples: Input: 3 Output: Yes 3 + 1 = 4 which is a perfect square i.e. 22 Input: 5 Output: No 5 + 1 = 6 which is not a perfect square. Recommended: Please try your approach on {IDE} first, before moving on to the solution. Approach: Check whether n + 1 is a perfect square or not by taking the square root of n + 1 and checking whether it is an integer. If it is then n + 1 is a perfect square and n is a sunny number. // C++ implementation of the approach #include using namespace std;
// Function that returns true // if x is a perfect square bool isPerfectSquare(long double x) {
// Find FLOATING point value of // square root of x long double sr = sqrt(x);
// If square root is an integer return ((sr - floor(sr)) == 0); }
// Function that returns true // if n is a sunny number bool isSunnyNum(INT n) {
// If (n + 1) is a perfect square if (isPerfectSquare(n + 1)) |

6^3x+3=216^3-x find x pls |

Answer» x3−216=0 Add 216 to both sides of the equation. x3=216 Move 216 to the LEFT SIDE of the equation by subtracting it from both sides. x3−216=0 Factor the left side of the equation. Tap for fewer steps... Rewrite 216 as 63 . x3−63=0 Since both TERMS are perfect cubes, factor using the difference of cubes formula, a3−b3=(a−b)(a2+ab+b2) where a=x and b=6 . (x−6)(x2+x⋅6+62)=0 Simplify. (x−6)(x2+6x+36)=0 SET x−6 equal to 0 and solve Set the factor equal to 0 . x−6=0 Add 6 to both sides of the equation. x=6 Set x2+6x+36 equal to 0 and solve for x Set the factor equal to x2+6x+36=0 Use the quadratic formula to find the solutions. −b±√b2−4(ac)2a Substitute the values a=1 , b=6, and c=36 into the quadratic formula and solve for x −6±√62−4⋅(1⋅36)2⋅1 Simplify x=−3±3i√3 Simplify the expression to solve for the + portion of the ± x=−3+3i√3 Simplify the expression to solve for the − portion of the ± . Tap for fewer steps... Simplify the numerator.
