Answer:
First, let's find out the sum;
1.30 + 1.25 = 2.55, is rational, so A
Step-by-step explanation:
The reason being this is because, 2.55 is a terminating decimal meaning that the decimal place does not go on forever.
Sara's classification is not correct because the sum is a rational number.
What is an irrational number?Irrational numbers are real numbers that cannot be expressed in fractions.
First, we can find the sum
i.e 1.3+1.25 = 2.55
Here, 2.55 is a rational number.
51/20 = 2.55
Since the sum is a rational number Sarah is not correct.

Evaluate the function below for x = 4.
F(x) = x3 + 2x^2 + 1
Given parameters:
x = 4
Function;
F(x) = x³ + 2x² + 1
Solution:
This is a function related problem.
A function shows the relationship between two sets usually a domain and its range.
For the given function;
F(x) = x³ + 2x² + 1
F(4) = 4³ + 2(4)² + 1
F(4) = 64 + 32 + 1 = 97
The value of the function is 97.
Answer: would be 97 :)

What is the second number of an ordered pair called
The second number in the ordered pair is the y coordinate.
The second value of an ordered pair is the y-value.
It signifies how far above (or below) the x axis o (horizontal axis) that a point is. If the y value is positive, then the point is above the x-axis, but if it is negative it is below the x axis (when it's 0, the point is on the x-axis)
**NOTE** the x and y axes are on the Cartesian plane
if sinA-cosA=0, What is the value of TanA and SecA?
Answer:
tan(x) = 1
sec(x) = sqrt(2)
Step-by-step explanation:
(Reminder: sin is the height of the triangle of the unit circle and cos is the length)
The only values where a right triangle with a hypotenuse of 1 has equal lengths of legs are 45-45-90 triangles. The sin and cosine of those triangles are both 1/sqrt(2).
Since tan(x) = sin(x)/cos(x), and sin(x) = cos(x), tan(x) is just going to be 1.
sec(x) is defined as 1/cos(x). since cos(x) is 1/sqrt(2), sec(x) is just sqrt(2).

Find rise, run and slope values
From the given graph, the rise, run and slope of this graph are 1, 5, and 1/5 respectively.
Slope of a LineThis is the ratio between the rise and run i.e y-axis and x-axis.
The rise any graph is the change in the y-axis.
Rise[tex]\delta y = y_2 - y_1[/tex]
The rise in this graph will be
[tex]\delta y = 1 - 0 = 1[/tex]
RunThe run on any graph is the change in the x-axis.
[tex]\delta x = x_2 - x_1[/tex]
The run on this graph is
[tex]\delta x = 5 - 0 = 5[/tex]
Having the values of rise and run, we can find the slope of this graph
[tex]m = \frac{\delta y}{\delta x} = \frac{1}{5}[/tex]
The rise, run and slope of this graph are 1, 5, and 1/5 respectively.

Step-by-step explanation:
Multiple each term in the first parentheses by each term in the second parentheses (FOIL)
2×5 + 2×6j - 8j×5 - 8j×6j
Multiple the numbers
=10 + 2 × 6j - 8j × 5 - 8j × 6j
=10 + 12j - 8j × 5 - 8j × 6j
=10 + 12j - 40j - 8j × 6j
= 10 + 12j - 40j - 48j²
Collect like terms
10 - 28j - 48j²
Reorder the terms using the commutative property

Wendi is 6 years older than Zaviel. The sum of their ages is 30. Which of these systems of equations can be used to find Wendi's age (w) and Zaviel's age (z)?
The system of equations for the ages of Wendi and Zaviel can be obtained as x = y + 6 and x + y = 30 respectively.
What is a system of linear equations?A system of linear equations is a group of equations having same number of variables and degree.
For the n number of variables n number of equations are required.
On the basis of number of solutions a system of equations can be classified as consistent and inconsistent.
Suppose the age of Wendi and Zaviel be x and y respectively.
Then, the equation for their age can be written as,
x = y + 6
And, the equation for the sum of ages is given as,
x + y = 30
Hence, the equations that represent the given case are x = y + 6 and x + y = 30 respectively.

A square bedroom has an area of 121 square feet. What is the perimeter
of the bedroom
Answer:
Step-by-step explanation:
Area of the square bed room is given. From this area, we need to find the sides of the square by taking square root of the area.
Side of the square bedroom = √area
[tex]= \sqrt{121} = \sqrt{11*11}\\\\= 11 \ ft[/tex]
Perimeter = 4 * side
= 4 *11
= 44 ft
