Answer:
Structure of Mathematical Systems Mathematics can be divided into four major areas- higher arithmetic, algebra, geometry, and analysis.
Answer:
Sorry I didn't get the answer option first
Step-by-step explanation:
higher arithmetic, algebra, geometry, and analysis.
Arithmetic: It is the oldest and the most elementary among other branches of mathematics. It deals with numbers and the basic operations- addition, subtraction, multiplication, and division, between them.
Algebra: It is a kind of arithmetic where we use unknown quantities along with numbers. These unknown quantities are represented by letters of the English alphabet such as X, Y, A, B, etc. or symbols. The use of letters helps us to generalize the formulas and rules and also helps you find the unknown missing values in the algebraic expressions and equations.
Geometry: It is the most practical branch of mathematics that deals with shapes and sizes of figures and their properties. The basic elements of geometry are points, lines, angles, surfaces and solids.
There are some other branches of mathematics that you would deal with in the higher classes.
Trigonometry: Derived from two Greek terms, i.e., trigon (means a triangle) and metron (means measurement), it is the study of relationships between angles and sides of triangles.
Analysis: It is the branch that deals with the study of the rate of change in different quantities. Calculus forms the base of analysis.

Which model can be used to show the correct product of 0.60 and 0.40?
The correct product of 0.60 and 0.40 is 0.24 and the model used to describe is bottom left.
Let us find the product of 0.60 and 0.40.
Multiply the two numbers without considering the decimal point.
0.60 × 0.40
= 0.24
Let us consider the boxes as 1.
Now we have to find the number of boxes which are shaded for 24.
Hence, the correct product of 0.60 and 0.40 is 0.24 and the model used to describe is bottom left.

Answer:
A. (12, -6)
Step-by-step explanation:
When a coordinate gets rotated into the bottom right quadrant of a graph, the x and y coordinates switch places and the y-coordinate becomes negative.
Since the coordinate pair was (6, 12), you would switch the spots of the coordinates to get (12, 6).
After that, make the y-coordinate negative (if the y-coordinate was originally negative, make it positive instead) to get (12, -6).
Therefore, the answer is (12, -6).

Then, rotate 90° counterclockwise.
First, rotate 270° counterclockwise around the origin.
Then, reflect across the x-axis.
First, reflect across the x-axis.
Then, reflect across the y-axis.
Figure
The given transformations are rigid transformation in which the image
can be located by a formula.
Response:
First reflect across the x-axis then reflect across the y-axisFigure: Second graph
First, rotate 180° counterclockwise around the origin. Then reflect across the x-axis.Figure: Third graph
First translate 9 units to the left. Then reflect across the x-axisFigure: First graph
What is the method to determine the transformation of an image?The coordinates of (x, y) following a reflection across the x-axis is (x, -y)
The coordinates following a reflection across the y-axis is (-x, y)
here, we have,
The points of the triangle following the first transformation is therefore;
(4, 4) → (4, -4) → (-4, -4)
(8, 4) → (8, -4) → (-8, -4)
(6, 6) → (6, -6) → (-6, -6)
The image from the first transformation is (-4, -4), (-8, -4), (-6, -6), which
corresponds to the second graph.
The coordinates following a rotation of (x, y) by 180° about the origin is (-x, -y)
A reflection of the point (-x, -y) about the x-axis is (-x, y).
Therefore;
(4, 4) → (-4, -4) → (-4, 4)
(8, 4) → (-8, -4) → (-8, 4)
(6, 6) → (-6, -6) → (-6, 6)
The image from the second transformation is (-4, 4), (-8, 4), (-6, 6), which corresponds to the third graph.
The coordinates following a translation of 9 units to the left is (x - 9, y)
A reflection of the point (x - 9, y) about the x-axis is (x - 9, -y)
Therefore;
(4, 4) → (4 - 9, -4) = (-5, -4)
(8, 4) → (8 - 9, -4) = (-1, -4)
(6, 6) → (6 - 9, -6) → (-3, -6)
The image from the third transformation is (-13, -9), (-1, -4), (-7, -6), which corresponds to the first graph.

Step-by-step explanation:
We are told the cost of the fabric per meter, so we first need to convert 250 cm into meters.
1 meter = 100 cm
Therefore, 250 cm = 250 ÷ 100 = 2.5 meters
cost of fabric = $15.40 per meter
To calculate the total cost, mulitply the length in meters by 15.40:

Please hurry on an exam The formula for calculating simple interest is I = prt. Which is the equivalent equation solved for r?
StartFraction I Over p t EndFraction = r
StartFraction p t Over I EndFraction = r
I minus p t = r
I + p t = r
Answer:
r=I/pt
Step-by-step explanation:
I = PRT is the formula for interest, and we need to solve it for R. Since all three of P, R, and T are multiplied, we send things to the other side of the equals through dividing. I = PRT I / P = RT to divide both sides by P I / PT = R to divide both sides by T So I / PT = R (the first choice) is the equation solved for R.

Describe the relationship between the number of feet and the number of yards.
Write an expression for the number of yards in f feet.
Find the number of yards in 63 feet.
Answer:
answer:
1Yarda = 3 feet
y = (1/3) f
y = 21
Step-by-step explanation:
The first thing we should do is see what relationship we have:
Table is feet to yards 3-1
a. Describe the relationship between the number of feet and the number of yards
That is to say:
1Yarda = 3 feet
b. Write an expression for the number of yards in f feet
Let
y = Yard
f = feet
We have the following expression for the conversion:
y = (1/3) f
c. Find the number of yards in 63 feet
For this case we must substitute in the expression found the value of f = 63.
y = (1/3) f
y = (1/3) (63)
y = 21
(pls mark me the Brainliest)
Answer:
There are 3 feet per yard
# of yards = 3f
189 feet
Step-by-step explanation:
f = feet
y = yard
First Question: Dividing the # of feet by # of yards for one column will always equal 3. So there are 3 feet per 1 yard
Examples: 3/1=3, 6/2=3, 9/3=3 ...
Second Question: To find the number of yards, divide the number of feet by 3. In other words, f/3=y
Third Question: Using the expression f/3=y, there are 21 yards in 63 feet
Prosses:
f/3=y
63/3 = y
21 = y

x<2.1 is the simplified inequality.
What is an inequality?An inequality is an inequation separated by <,>≥,≤. In Mathematics, the relationship between two values that are not equal is defined by inequalities. Inequality means not equal. Generally, if two values are not equal, we use “not equal symbol (≠)”
Given here: The inequality -4x>8.4
multiplying by -1/4 both sides we get
4x/4 < -8.4/4
x<-2.1

Mia paddled her canoe from the shore of a lake to an island. She stopped on the island to eat lunch, and then paddled her canoe back to the shore. The graph below shows Mia’s distance, in kilometers, from the shore over time. Based on the graph, which of the following statements is true?
The speed of Mia on the way back to the shore is greater than speed on the way to the island
What is Speed?Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the speed on the way to the island be S₁
Let the speed on the way back to the shore be S₂
where the Speed = Distance / Time
So , S₁ = ( 3 - 0 ) / ( 40 - 0 )
S₁ = 3/40 km/minutes
S₁ = 0.075 km/minutes
And , S₂ = 0.1 km/minutes
Now , S₂ > S₁
Hence , the speed on the way back to the shore is greater
