There are 1200 students in a school. 51.5% of them are male. How many are female?
Answer:
582
Step-by-step explanation:
1200 - (1200 * (51,5%)) = 582
Answer:
582
Step-by-step explanation:
Given
Total number of students = 1200
% of male students = 51.5%
Now first calculating the number of males
= 51.5% of 1200
= 51.5 / 100 * 1200
= 618
Now Number of female students
= 1200 - 618
=582

What is the area, in square units, of ΔDEF with D(5,−1) E(1,−4), and F(−5,4)?
A. 25 square units
B. 37.5 square units
C. 50 square units
D. 75 square units
Answer:
25
Step-by-step explanation:
The line DF is
y+1 = -1/2 (x-5)
or
x+2y-3=0
The distance from E to that line is |1-8-3|/√(1^2+2^2) = 10/√5
The length of DF is √(10^2+5^2) = 5√5
So the area of DEF is 1/2 * 5√5 * 10/√5 = 25

JK = 29LM = 29KL = 10MJ = 10JK = LM and KL = MJ========================================================
Explanation:
Let's plug in the given x value
JK = 5x+9 = 5*4+9 = 20+9 = 29LM = 6x+5 = 6*4+5 = 24+5 = 29Both JK and LM are equal to 29, so this means JK = ML
Now use the y value
KL = 2y-6 = 2*8-6 = 16-6 = 10MJ = y+2 = 8+2 = 10Both JM and KL are equal to 10, so JM = KL
These facts are sufficient to prove we have a parallelogram.

Help
Answer:
Step-by-step explanation:
If an exponential function is in the form of y = a(b)ˣ,
a = Initial quantity
b = Growth factor
x = Duration
Condition for exponential growth → b > 1
Condition for exponential decay → 0 < b < 1
Now we ca apply this condition in the given functions,
1). [tex]y=3.2(1+0.45)^{2x}[/tex]
Here, (1 + 0.45) = 1.45 > 1
Therefore, It's an exponential growth.
2). [tex]y=(0.85)^{3x}[/tex]
Here, (0.85) is between 0 and 1,
Therefore, it's an exponential decay.
3). y = (1 - 0.03)ˣ + 4
Here, (1 - 0.03) = 0.97
And 0 < 0.97 < 1
Therefore, It's an exponential decay.
4). y = 0.5(1.2)ˣ + 2
Here, 1.2 > 1
Therefore, it's an exponential growth.

A rectangular region is removed from another rectangular region to create the shaded region shown below. Find the area of the shaded region.
7 yd
11 yd
4 yd
8 yd
The area of the shaded region is 60 square units.
What is Area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
To find the area of the shaded region, we need to subtract the area of the rectangular region that was removed from the larger rectangular region.
The area of the larger rectangle is:
11 x 8 = 88
The area of the rectangle that was removed is:
7 x 4 = 28
So, the area of the shaded region is:
88 - 28 = 60
Therefore, the area of the shaded region is 60 square units.

Which expression is a monomial?
X
O 3x0.5
O x +1
07
Answer: D
Step-by-step explanation:
Expression X is monomial. Out of the 4 options, option (1) is correct.
A monomial is a mathematical expression that consists of a single term
Let's check for each option and see whether it is a monomial or not:
1) X :
This option is a monomial, since the variable "X" itself is the only term in it. It is not associated with any exponents or coefficients.
2) [tex]3x^{0.5}[/tex] :
Because it contains a component with an exponent of 0.5, this choice is not a monomial. Exponents on a monomial should be integers. Exponents cannot be fractions or decimals; they must be entire numbers.
3) x+1:
Because it is a binomial, this alternative is not a monomial. There are two words in it: "x" and "1," which are separated by the plus symbol. A monomial ought to include just one word.
4) 07:
07 is not a monomial because it contains two terms, 0 and 7.
Hence, option (1) is a correct choice.

Identify the numerical coefficient, the variable,
and the constant term in each algebraic expression.
a) 3x + 2
Answer:
A numerical coefficient is a constant multiplier of the variables in a term. so it would be 3x cause it has a number and a variable.
a variable is a symbol which functions as a placeholder for varying expression or quantities, so x is the variable.
a constant term is a term in an algebraic expression that has a value that is constant or cannot change, because it does not contain any modifiable variables. so it would be the 2
Step-by-step explanation:
The numerical coefficient, the variable, and the constant term in each algebraic expression are; 3x , x , and 2 respectively.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Given 3x + 2
A numerical coefficient is a constant multiplier of the variables in a term. it would be 3x since it has a number and a variable.
A variable is a symbol which functions as a placeholder for varying expression or quantities, thus x is the variable.
A constant term is a term in an algebraic expression that has a value that is constant or cannot change, so it would be the 2

320 is what percent of 200?
320 is 160 percent of 200.
To determine what percent 320 is of 200, we can use the formula for calculating the percentage:
(320 / 200) x 100
First, we divide 320 by 200:
320 / 200 = 1.6
Next, we multiply the result by 100 to obtain the percentage:
1.6 x 100 = 160
Therefore, 320 is 160% of 200.
To understand this, we can think of it as comparing 320 to the whole quantity of 200. When we express 320 as a percentage of 200, it means 320 is 160% of 200, indicating that it is 1.6 times the value of 200. In other words, 320 is 60% more than 200.
The percentage calculation allows us to understand the relative proportion or ratio between two values and express it as a percentage of the whole.

The iota is a complex notation represented by the letter i in complex number.
iota power 2 can also be written as;
i^2
In complex number, the square root of -1 is iota. This can be expressed as;
[tex]\sqrt{-1} = i[/tex]
Take the square of both sides
[tex](\sqrt{-1})^2 = i^2\\-1 = i^2\\Rearrange\\i^2 = -1[/tex]
