What is 1/20 as a percentage
Answer:
1/20 = 5%
Hope this helps with your question :)
Step-by-step explanation:
1. Multiply numerator and denominator by 5 to get 100 in the denominator.
1/20 = 5/100
2. A number over 100 means it is that number on top of 100.
5/100 = 5% out of 100%
3. So final answer is 5%
five balls are randomly chosen, without replacement, from an urn that contains 5 red, 6 white, and 7 blue balls. find the probability that at least one ball of each color is chosen.
The probability that at least one ball of each color is chosen is 105/8568.
Given that:-
Number of red balls in the urn = 5
Number of white balls in the urn = 6
Number of blue balls in the urn = 7
We have to find the probability that at least one ball of each color is chosen.
Let us consider the that 1 ball of each color has been chosen.
Hence, we are left with 4 red balls, 5 white balls and 6 blue balls.
Now we have to choose 2 balls from them.
Hence,
Number of ways in which we can choose 2 balls from (4+5+6) that is 15 balls = [tex]^{15}C_2=105[/tex]
Total number of ways in which we can choose 5 balls from 18 balls =
[tex]^{18}C_5=8568[/tex]
Hence,
Probability that at least one ball of each color is chosen = 105/8568

The mass ratio of the rocket is 10.8468 kg/C.
What is mass ratio of a rocket?An indicator of a rocket's effectiveness is its mass ratio. It describes the ratio of the rocket's wet mass to its dry mass, or how much more massive the vehicle is with propellant than without.Given:
v = - 0.0098(t) + c (ln (R) ), where:v = maximum shuttle velocityt = firing timec = velocity of exhaustR = mass ratioHere, c = 3.1 km/s, t = 50s, v = 6.9km/sTo find: Mass ratio (R) = ?
Finding:
On substituting the values of 'c', 't', 'v', we get:
6.9 = - 0.0098 (50) + 3.1 (ln (R) )
=> 6.9 + 0.49 = 3.1 (ln (R) )
=> 7.39 = 3.1 (ln (R) )
=> ln (R) = [tex]\frac{7.39}{3.1}[/tex]

Find any points of discontinuity for each rational function. y= x²-x-2 / 3 x²-7 x+2
The point of discontinuity for y= x²-x-2 / 3 x²-7 x+2 is x= 1/3 and x= 2.
What is discontinuous function?
Mathematics, functions, and applications all place a premium on continuous functions. But not every function is continuous. A function is said to have a discontinuity there if it is not continuous at that point in its domain.
Given,
y = x²-x-2 / 3 x²-7 x+2
It can be expressed in the form of -
⇒ y = (x-2) (x+1) / (3x-1) (x-2)
The function will be undefined if the denominator will be 0
⇒ 3x-1 = 0
⇒ x = 1/3
⇒ x-2 = 0
⇒x = 2

A high school decided to spend $ 750 on student academic achievement awards. At least 5 awards will be given, they should be equal in value, and each award should not be less than $ 50 . Write and sketch a function that models the relationship between the number a of awards and the cost c of each award. What are the domain and range of the function?
a. Which equation describes the relationship between a and c ?
Equation that describes the relationship between a and c is c = 750 / a
The domain of the function is - 5 ≤ a ≤ 50
The range of the function is - 50 ≤ c ≤ 150
Given,
Total money spent is = $750
Thus, our equation become,
ca = 750
solving for c,
c = 750 / a
The domain and range of function is -
a ≤ 5
Now, each award should be less than 50.
= 50 ≤ c
using equation, ac = 750
maximum value for a = 75.
we can say that domain is
5 ≤ a ≤ 50
Finally, by substituting a = 5 we can see that the maximum for c is 150.
This gives range for c as -

In the image above angle 3 is 79 degrees, what is angle 11?
Since in the image above angle 3 is 79 degrees, angle 11 is also equal to 79 degrees based on the vertical angles theorem.
What are parallel lines?Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.
What is the vertical angles theorem?The vertical angles theorem is also referred to as vertically opposite angles theorem and it states that two (2) opposite vertical angles that are generally formed whenever two (2) lines intersect each other are always congruent, which simply means being equal to each other.
In Geometry, when two (2) parallel lines are cut by a transversal, the interior angles that are formed on the same side of the transversal are supplementary angles, which makes:
Angle 3 = Angle 14
Angle 14 = Angle 9
Angle 3 ≅ Angle 9 (Congruent angles or supplements of the same angle)
By applying the vertical angles theorem, we have:
Angle 9 ≅ Angle 11 = 79 degrees.

The perimeter of the polygon is 12.
The perimeter of a closed figure is the sum of the lengths of its outermost sides. It is the sum of the lengths of a polygon's sides. All sides add up to the perimeter.
The distance between the two points A(x, y) and B(x₁, y₁ ).
AB = √ [ (x₁ - x)² + (y₁ - y)² ]
Consider the vertices U ( -1, 4), V (3, 4), W (3, 1).
Then,
UV = √ [ ( 3 +1)² + (4 - 4)² ] = √4² = 4
VW = √ [ ( 3 - 3)² + ( 1 - 4)² ] = √(- 3)² = 3
UW = √ [ ( 3 + 1)² + ( 1 - 4)² ] = √ [ ( 4)² + (-3)² ] = √ [ 16 + 9 ] = √25 = 5

The measure of the angles m∠JKL = (10x + 5)° and m∠PLK = (12x - 1)° are 25 degrees and 23 degrees respectively.
What are parallel segments?Parallel segments are defined as lines on a plane that never meets.
The properties of parallel segments include:
The vertically opposite angles are equalThe corresponding angles are equalThe alternate exterior angles are equalThe alternate interior angles are equalGiven the angles;
m∠JKL = (10x + 5)° m∠PLK = (12x - 1)°We can see that the two angles are vertically opposite angles and thus equal.
Then,
m∠JKL = m∠PLK
substitute the values
10x + 5 = 12x - 1
collect like terms
10x - 12x = -1 - 5
-2x = - 6
Make 'x' the subject of formula
x = 3
But:
m∠JKL = (10x + 5)° = 10(2) + 5 = 25°
m∠PLK = (12x - 1)° = 12(2) - 1 = 23°

Using given algebraic equation, Keelan collected 431 tokens.
What is an algebraic equation?In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.). Terms comprise expressions.
At least one variable and one operation must be present in an algebraic expression (addition, subtraction, multiplication, division). One such algebraic statement is 2(x + 8y).
You must substitute a number for each variable and carry out the arithmetic operations in order to evaluate an algebraic statement. Since 6 + 6 equals 12, the variable x in the example above is equal to 6. If we are aware of the values of our variables, we may substitute those values for the original variables before evaluating the expression.
Given,
p=20x+75
p = 8695
