20 is 200 percent of what number?
The answer is 10. let the number be k its given that 200% of that number is 20 In symbolic form, 200% of k = 20 200 per cent of k = 20 200/100 of k = 20 200/100 x k = 20 [of indicates multiplication] 2 x k = 20 k = 20/2 k = 10
What k -k equals 2?
k and -k right? -k x -1 =k k+k= 2 k= 1 unless you mean multiply then that would be -k x-1 =k k x k= 2 1.4142 rounded to the nearest ten thousandth
Factor the expression 2 k squared minus k minus 4 equals 0?
2 k^2 - k - 4 = 0 2 (k^2 - (1/2)k - 2) = 0 2 ((k - 1/4)^2 - 1/16 - 2) = 0 2 ((k - 1/4)^2 - 33/16) = 0 2 (k - 1/4 - sqrt(33)/4)(k - 1/4 + sqrt(33)/4) = 0 32 (4k - 1 - sqrt(33))(4k - 1 + sqrt(33)) = 0
What does 20 k mean on jewelry?
It means 20 karat gold
K divided by 2 - k divided by 5- k divided by6 equals 2?
k/2 -k/5 -k/6 = 2 Multply all terms by 30: 15k -6k -5k = 60 4k = 60 k = 15

What is the reciprical of 20 percent?
20% means 20/100 Hence its reciprocal is 100/20 = 10/2 = 5
What are the possible values of k in the line y equals 2x plus k that makes contact with the circle x2 plus y2 equals 4?
If: y = 2x+k then y^2 = 4x^2 +4kx +k^2 If: x^2 +y^2 = 4 then 5x^2 +4kx +(k^2 -4) = 0 Using the discriminant: (4k)^2 -4*5*(k^2 -4) = 0 Removing brackets: 16k^2 -20k^2 +80 = 0 Collecting like terms and subtracting 80 from both sides: -4k^2 = -80 Dividing both sides by -4: k^2 = 20 Square root both sides: k = - square root of 20 and k = + square root of 20 Therefore possible values of k are - square root of 20 and + square root of 20
What are the possible values of k when y equals 2x plus k is a tangent to the circle x2 plus y2 equals 4?
If: y = 2x+k then y^2 = 4x^2 +4kx +k^2 by squaring both sides If: x^2 +y^2 = 4 then x^2 +4x^2 +4kx +(k^2 -4) = 0 So: 5x^2 +4kx +(k^2 -4) = 0 Using the discriminant: (4k)^2 -4*5*(k^2 -4) = 0 Solving the discriminant: k = -square root of 20 or +square root of 20
What are the release dates for Cavalcade of America - 1952 Duel at the O-K- Corral 2-20?
Cavalcade of America - 1952 Duel at the O-K- Corral 2-20 was released on: USA: 9 March 1954
Factor 7k squared plus 7k-140?
7k^(2) + 7k - 140 Factor out '7' Hence 7(k^(2) + k - 20) Factor inside the brackets 7(k + 5)(k - 4) Done!!!!
What are the common multiples of 2 4 and 5?
They are members of the infinite set of numbers of the form 20*k where k is an integer. Since the set is infinite, it is not possible to list them.They are all the multiples of 20.
What is the equation of the circle with a center of 2 and 1 and a radius of 20?
The equation of a circle can be expressed in the standard form ((x - h)^2 + (y - k)^2 = r^2), where ((h, k)) is the center and (r) is the radius. Given the center at ((2, 1)) and a radius of (20), the equation becomes ((x - 2)^2 + (y - 1)^2 = 20^2). Simplifying this, we have ((x - 2)^2 + (y - 1)^2 = 400).
What is 37-k equals 17?
It is an equation. Taking it step by step: 37 - k = 17 -k = 17 - 37 -k = -20 k = 20
20 Celsius equals to how many k?
20 deg Celsius = 20 + 273.15 = 293.15 K
What is -17 37?
It is an equation. Taking it step by step: 37 - k = 17 -k = 17 - 37 -k = -20 k = 20
The vertex of a parabola is (-2 -20) and its intercept is (0 -12).?
To find the equation of the parabola, we can use the vertex form, which is (y = a(x - h)^2 + k), where ((h, k)) is the vertex. Substituting the vertex ((-2, -20)), the equation becomes (y = a(x + 2)^2 - 20). Using the intercept ((0, -12)) to find (a), we substitute (x = 0) and (y = -12), resulting in (-12 = a(0 + 2)^2 - 20). Solving for (a) gives (a = 2), leading to the final equation (y = 2(x + 2)^2 - 20).
