What is percentage ?
A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement.
In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. Percentage, a relative value showing hundredth parts of any amount, is a relative measure that indicates how many questions on a test you correctly answered out of 100 (75/100). Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified percentage.
20000( 1 - 9% )^5
≈ 12481
12481 < 13000

What value of n makes the equation true? Show your work.
Answer:
n=13
Step-by-step explanation:
When multiplying two numbers with the same base, add the exponents

June rolls a fair dice 234 times.
How many times would June expect to roll a one?
Answer: 39 times
Step-by-step explanation: A fair dice has 6 sides with each side having a different number between 1 and 6. Therefore, the probability of rolling a 1 is 1/6. To find out how many times June would expect to roll a 1 after rolling the dice 234 times, you must multiply 234 by 1/6 to get the answer of 39.

Help plz...And No links!!I repeat No links!!
Answer:
36 units
Step-by-step explanation:
First calculate the length of side a. Using the Pythagorean Theorem, we find that 15^2 = 12^2 + x^2, or 225 - 144 = x^2. Thus, x^2 = 81 and the length of side a is √81, or 9, units.
Then the perimeter is the sum of all three side lengths:

What is the modulus of 2 - 3i?
Oi
O √√√5
O

O√13
The modulus of 2 - 3i is √13. So, the correct option is d.
What is modulus?Modulus is a mathematical operation used to find the remainder when dividing two numbers. This is called a percent sign (%) and is represented by a single number such as 12. Used to determine if two numbers are divisible (no remainder). You can also use the modulus to compare two numbers to see which is greater or lesser. Additionally, this module can be used to calculate the distance between two points on the coordinate plane.
It is computed by taking the square root of the sum of the squares of the real and imaginary components, so √(2^2 + (-3)^2) = √13. The modulus of a complex number, also called absolute value, is a measure of distance from the origin.
Let z = -2 - 3i
z = (-2) + (-3)i
Modulus of z = √((-2)² + (-3)²)
√(4 + 9) = √13
Modulus of z = √13

john is 7 years younger than jane. the sum of their age is 10 years ago was 55 years. how old are they now
Answer: John is 29 years old and Jane is 36 years old.
Step-by-step explanation:
There are many parts to this problem, so let's start by defining John as x and Jane as y.
We know that the sum of their age 10 years ago was 55, which gives us x+y-10=55. The reason we put -10 is because of 10 years ago. If you think about it in terms of now, 10 years back is 55, so now they would be 65 years old. So we can have either x+y-10=55 or x+y=65. For simplicity, I will use x+y=65.
We also know that John is 7 years younger than Jane, which gives x=y-7.
Luckily, we have x defined for us, so we can directly substitute that into our equation.
[tex](y-7)+y=65[/tex] [combine like terms]
[tex]2y-7=65[/tex] [add both sides by 7]
[tex]2y=72[/tex] [divide both sides by 2]
[tex]y=36[/tex]
Now we know that y=36, we can plug that into either equations to find x.
[tex]x+36=65[/tex] [subtract both sides by 36]
[tex]x=29[/tex]
This concludes that John is 29 years old and Jane is 36 years old.

The difference between ( -7×-7) + -(7×7) is
A)98. B)28
C)0. D)-28
To find the difference between (-7*-7) + -(7*7), we first need to calculate the values of each expression.
(-7*-7) = 77 = 49
-(77) = -49
The difference between these two values is 49 - (-49) = 49 + 49 = 98.
Therefore, the answer is A) 98.
The Correct answer is Option (A) = 98.
We need to determine the value of each part and calculate their difference. after that.
Here, (-7*-7)= 49
and, -(7*7) = -49
Now, their difference is to be calculated as follows:
=49 - (-49)
= 49+ 49
= 98.
So, the answer is 98.

A cylindrical water tank of height 4 m is used to fill containers with dimensions 20 cm X 30 cm X 50 cm. If the tank can fill exactly 200 of these containers, find its base radius. (Take Pi = 3.14)
Answer:
0.35cm
Step-by-step explanation:
Step 1
We find the volume of the container.
The formula = Length × Width × Height
Length = 20cm
Width = 30cm
Height = 50cm
The volume of the tank = 20cm × 30cm × 50cm
= 30000 cm³
Step 2
We are told that:
The tank can fill exactly 200 of these containers
We have to find the volume that 1 cylinder will contain
Hence,
200 containers = 30000 cm³
1 container = x
Cross Multiply
200 × x = 30000cm³
x = 30000cm³/200
x = 150cm³
Step 3
We find the base radius of the cylindrical tank
Height = 4m
Convert to cm
1m = 100cm
4m = x
Cross Multiply
x = 4 × 100cm = 400cm
Volume of the cylinder = πr²h
Radius = √V/πh
Radius = √150/π × 400
Radius = 0.35 cm
Therefore, base radius = 0.35cm

The auditorium seated 375, but this was enough for only 30% of those who wanted a seat. How many wanted a seat but couldn't get one?
Answer: 875 people
Step-by-step explanation:
The 375 people seated represent 30% of the total number of people who wanted seats but these ones got them.
This means that the number of people who wanted seats is 70% of the number of people who wanted seats.
Assume the number of people who wanted seats is x:
30% * x = 375
x = 375 / 30%
x = 1,250 people wanted seats.
Those who wanted seats but couldn't get:
= 1,250 * 70%
= 875 people
How do you find the ordered pair?
On a Cartesian (or "coordinate") plane in which each point is represented by an ordered pair (x , y) belongs to x coordinate , y coordinate .
An ordered pair is a set of numbers in which it gives the location of a point on a coordinate plane.
The ordered pair is always expressed exactly the same way (x , y).
The first number in an ordered pair represents the x coordinate on the plane while the second number in an ordered pair represents the y coordinate.
The x-coordinate shoes that how far away the point is horizontally from the x-axis.
The y-coordinate shows that how far away the point is vertically from the x-axis.
Quadrant I: the upper-right quadrant of the plane in which all points in this quadrant have the positive x coordinates and positive y coordinates as { (+,+)} , {(+,+)}
Quadrant II: the upper-left quadrant of the plane in which all points in this quadrant have negative x coordinates and positive y coordinates
{ (+,-)}{ (+,-)}
Quadrant III: the lower-left quadrant of the plane in which all points in this quadrant have negative x coordinates and negative y coordinates
{ (-,-)}{(-,-)}
Quadrant IV: the lower-right quadrant of the plane in which all points in this quadrant have positive x coordinates and negative y coordinates

The polygons are similar. x = ___ Write your answer as a decimal
By using the fact that the two images are similar, we can write and solve a linear equation to get x = 3/2.
How to find the value of x?We know that the two figures are similar, then, if we take the quotient between the adjacent sides for both figures, these quotients should give the same value.
Thus, we can write the equation:
14/10 = (x + 9)/(x + 6)
Now we can solve that equation for x, if we multiply both sides by (x + 6) we will get:
(14/10)*(x + 6) = x + 9
Now we can multiply both sides by 10 to get:
14*(x + 6) = 10*(x + 9)
14x + 84 = 10x + 90
Now we can solve this linear equation for x.
14x - 10x = 90 - 84
4x = 6
x = 6/4
x = 3/2
That is the value of x.
