Place the two large triangles around the square to form a triangle, a parallelogram, and a trapezoid.
Answers
To form a triangle, parallelogram, and trapezoid using two large triangles and a square, we can arrange them as follows:
Place the square horizontally on the bottom.
Take one large triangle and place it on top of the square, aligning one side of the triangle with one side of the square.
Take the second large triangle and place it on top of the first triangle, aligning one side of the second triangle with the remaining side of the square.
The resulting shapes will be:
Triangle: Formed by the three sides of the two triangles that are not in contact with the square.
Parallelogram: Formed by the two sides of the second triangle that are in contact with the square, and the two sides of the square.
Trapezoid: Formed by the two sides of the first triangle that are in contact with the square, the two sides of the second triangle that are not in contact with the square, and one side of the square.
Note: Without specific dimensions or angles provided for the large triangles and the square, the resulting shapes may vary in size and proportions.

Leah flips a coin, and then she spins a spinner with 3 equal sections colored red, green, and blue. What is the probability that
the coin flips heads, and
the spinner lands on either red or blue?
Answers
The probability that the coin flips heads and the spinner lands on either red or blue is 1/3.
The probability of the coin flipping heads is 1/2, since there are two possible outcomes (heads or tails) and they are equally likely. The probability of the spinner landing on either red or blue is 2/3, since there are two desired outcomes out of three possible outcomes (red, green, or blue) and they are equally likely. To find the probability of both events happening, we multiply their probabilities:
1/2 x 2/3 = 1/3
Therefore, the probability is calculated as 1/3.

Answer:
428 square ft
Step-by-step explanation:
to do this you can break the shape up into multiple pieces
you can do it this way
the top left part of the polygon could be one shape
9 by 10
this is because if the left side is 23 and part of the left side is 13 the leftover part is 10
then the bottom is 13 by 26
then you multiply and add them together
(9 * 10) + (13 * 26) = 90 + 338
then you add
90 + 338 = 428

Let S be a relation on the set R of all real numbers defined by S={(a,b)∈R×R:a 2 +b 2 =1}. Prove that S is not an equivalence relation on R.
Answers
The relation S={(a,b)∈R×R:a²+b²=1} is not an equivalence relation on the set of real numbers R.
To show that S is not an equivalence relation, we need to demonstrate that it fails to satisfy one or more of the properties of an equivalence relation: reflexivity, symmetry, and transitivity.
Reflexivity: For a relation to be reflexive, every element of the set should be related to itself. However, in the case of S, there are no real numbers (a, b) that satisfy the equation a² + b² = 1 for both a and b being the same number. Therefore, S is not reflexive.
Symmetry: For a relation to be symmetric, if (a, b) is related to (c, d), then (c, d) must also be related to (a, b). However, in S, if (a, b) satisfies a² + b² = 1, it does not necessarily mean that (b, a) also satisfies the equation. Thus, S is not symmetric.
Transitivity: For a relation to be transitive, if (a, b) is related to (c, d), and (c, d) is related to (e, f), then (a, b) must also be related to (e, f). However, in S, it is not true that if (a, b) and (c, d) satisfy a² + b² = 1 and c² + d² = 1 respectively, then (a, b) and (e, f) satisfy a² + b² = 1. Hence, S is not transitive.
Since S fails to satisfy the properties of reflexivity, symmetry, and transitivity, it is not an equivalence relation on the set of real numbers R.

Answer:
P(roll less than 4) = 0.50
Step-by-step explanation:
First, we need to list the sample space.
\(S = \{1,2,3,4,5,6\}\)
From the above, we have that:
\(n(S) = 6\) i.e. total rolls
Represent Rolls less than 4 with L4; So,
\(L4 = \{1,2,3\}\)
\(n(L4) = 3\) i.e. number of rolls less than 4
The required probability is calculated as:
\(Probability = \frac{n(LA)}{n(S)}\)
\(Probability = \frac{3}{6}\)
\(Probability = 0.50\)

A. Amount(hours worked)
Step-by-step explanation:
Function notation is a way of converting a written description of a function to a concise form that is easy to read.
It is another way of representing the y-value in a function, y = ƒ(something)
Let's convert the word expression to function notation:
"The amount charged for labour depends on the time the repair technician works." "The amount depends on the hours worked." "The amount is a function of the hours worked." Amount = amount(hours worked) y = a(h)

Answers
Answer:
david would saved 20%
Step-by-step explanation:
The computation is shown below:
Given that
Anna saves 19%.
Laura spends 17 by 20 i.e. 85 by 100 so it saves 15%.
The ratio of david salary saved to spend be 2:8
20% : 80%
So david would saved 20%
This represent that most of the salary would spend by david

4. A school's cafeteria measuring 30 m by 20 m is to
be covered with square floor tiles of side 50 cm.
How many tiles are needed?
Answers
Length of cafeteria in cm = 30 m x 100 cm/m = 3000 cm
Width of cafeteria in cm = 20 m x 100 cm/m = 2000 cm
Next, we can calculate the area of the cafeteria floor in square centimeters:
Area of cafeteria floor = Length x Width = 3000 cm x 2000 cm = 6,000,000 cm^2
Finally, we can calculate the number of tiles needed by dividing the area of the floor by the area of each tile:
Area of each tile = 50 cm x 50 cm = 2500 cm^2
Number of tiles needed = (Area of cafeteria floor) / (Area of each tile) = 6,000,000 cm^2 / 2500 cm^2 = 2400 tiles
Therefore, 2400 tiles are needed to cover the cafeteria floor.

Answers
Using simultaneous equations, Kieran and Louise's numbers are 20 and 8 respectively.
How to represent situation with system of equation?Kieran and Louise each think of a number. 4 less than Kieran's number is equal to 2 lots of Louise's number.
let's
x = Kieran's number
y = Louise's number.
x - 4 = 2y
x - 2y = 4
3 lots of Kieran's number added to Louise's number is 68.
Hence,
3x + y = 68
Hence, let's combine the system of equation.
x - 2y = 4
3x + y = 68
multiply equation(i) by 3
3x - 6y = 12
3x + y = 68
-7y = -56
y = -56 / -7
y = 8
Therefore, let's find x
x = 4 + 2y
x = 4 + 2(8)
x = 4 + 16
x = 20
Hence,
Kieran number = 20

Integers are frequently represented as specially marked points evenly spaced on a line. Despite the fact that the image only shows the integers from -3 to 3, the line includes all real numbers, which continue indefinitely in each direction, as well as numbers that are between the integers. It is frequently used to help teach simple addition and subtraction, particularly with negative numbers.

C) 12
D) None of the above
Answers
The dot product of vectors a and b || a |= 6,|| b ||= 4 and the angle between the vectors θ = π/3 is (c) 12.
The dot product of two vectors, we can use the formula:
a · b = ||a|| ||b|| cos(theta)
where ||a|| and ||b|| represent the magnitudes of vectors a and b, respectively, and theta is the angle between the vectors.
In this case, we are given that ||a|| = 6, ||b|| = 4, and the angle between the vectors is theta = π/3.
Substituting these values into the formula, we have:
a · b = 6 × 4 × cos(π/3)
To evaluate cos(π/3), we can use the fact that it is equal to 1/2. So we have:
a · b = 6 × 4 × 1/2
= 12
Therefore, the dot product of vectors a and b is 12.

What is linear inequality?
Inequality denotes a mathematical expression in which neither side is equal. An inequality occurs when a connection produces a non-equal comparison between two expressions or two integers.
The equal sign "=" in the phrase is substituted by any of the inequality symbols, such as greater than symbol (>), less than symbol (<), greater than or equal to a symbol (≥), less than or equal to a symbol (≤), or not equal to a symbol (≠).
In mathematics, there are three types of inequalities: polynomial inequalities, rational inequalities, and absolute value inequalities.
The symbols "< and '>' represent strict inequalities, whereas ‘≤’ and ‘≥’ represent slack inequalities.
A linear inequality appears to be a linear equation, however, there is a difference in the formula.

a sequence of 14 bits is randomly generated. what is the probability that at least two of these bits is 1?
Answers
The probability that at least two of the 14 bits are 1 is approximately 0.9658 if a sequence of 14 bits is randomly generated.
Sequence number = 14
favourable outcome = 1
we can use the complement rule to calculate the probability that at least two of the 14 bits are 1.
The probability of a single bit 1 = 1/2
The probability of a single bit 0 = 1/2.
The probability that a single bit is not 1 = \((\frac{1}{2}) ^{14}\)
The probability that exactly one bit is 1 = \(14*(\frac{1}{2} ^{14} )\)
Therefore, the probability that at least two of the 14 bits are 1 is:
probability = 1 - \((\frac{1}{2} ^{14} ) - 14*(\frac{1}{2} ^{14} )\)
probability = 1 - \(15*( \frac{1}{2} ^{14} )\)
probability = 0.9658
Therefore we can conclude that the probability that at least two of the 14 bits are 1 is approximately 0.9658.
