The diagram below shows a square.
4r + 5
6x-2
Diagram not drawn to scale
All the lengths are measured in centimetres.
Find the length of one side of the square.
Answer:
19
Step-by-step explanation:
simple, since all sides of a square are equal, we have that;
6x - 2= 4x + 5
collect like terms
6x - 4x = 5 + 2
2x = 7
dividing throughout by 2
x = 7/2
x = 3.5
since x= 3.5 or 7/2, we can now find the length of one side of the square by simply substituting value of x for x.
6x - 2
6(7/2) - 2
21 - 2
length of a side of the square= 19
OR
4x + 5
4(7/2) + 5
14 + 5
length of a side of the square= 19

Miles and Lucy decide to sell lemonade to earn some money. They buy pitchers, ice, and mix for a cost of $13.50. The mix makes 8 quarts of lemonade. They decide to sell one cup of lemonade for $0.75. If they sell all 8 quarts, how much revenue will they make and will they make enough to earn $12 each? (4c=1q)
Answer:
Altogether they made $24 which is enough to earn $12 each
Step-by-step explanation:
Important information:
1 cup: $0.75
4 cups = 1 quart
8 quarts of lemonade altogether
If we are looking to solve for the revenue earned based on quarts, we must first solve for how much money they make on 1 quart
Since 1 cup sells for $0.75 and 4 cups makes up a quart, we must multiply
0.75 × 4 = 3
They make $3 per 1 quart
We are looking for the amount for 8 quarts though, not just 1. Again we must multiply
3 × 8 = 24
They will make $24 if they sell all 8 quarts
The questions ask if they will each earn $12
Since there are two of them, Miles and Lucy, we must divide revenue earned by 2, the number of people
24 ÷ 2 = 12
$12
Gametes are chosen at random to make zygotes. As the number of zygotes increases, what will happen
As the number of zygotes increases, it can lead to both increased genetic diversity and increased chances of beneficial or harmful traits.
These factors can play a role in shaping the evolution of a population over time.
As the number of zygotes increases, there are a few possible outcomes:
1. Increased genetic diversity:
When gametes are chosen at random to form zygotes, it increases the chances of combining different sets of genetic information. This can lead to an increase in genetic diversity among the zygotes.
2. Higher chances of beneficial traits:
With a larger number of zygotes, there is a higher probability of beneficial genetic variations occurring. These beneficial traits can provide advantages to the organism, such as improved survival or reproduction.
3. Increased chances of harmful traits:
On the flip side, as the number of zygotes increases, there is also a greater likelihood of harmful genetic variations occurring. These harmful traits can lead to decreased fitness or survival disadvantages for the organism.
4. Natural selection:
With an increased number of zygotes, there is a greater pool of potential variations for natural selection to act upon. Natural selection favors individuals with traits that are better suited to their environment, leading to the survival and reproduction of those individuals and their genetic traits becoming more common in subsequent generations.
Overall, as the number of zygotes increases, it can lead to both increased genetic diversity and increased chances of beneficial or harmful traits. These factors can play a role in shaping the evolution of a population over time.

As the number of zygotes increases, the genetic diversity within the population may increase, and the overall population size may also increase.
When gametes, which are the reproductive cells (sperm and egg), combine to form zygotes, the process is random. This means that the choice of gametes that come together to form a zygote is not predetermined or controlled.
As the number of zygotes increases, there are a few possible outcomes. One possible outcome is that the genetic diversity within the population will also increase.
This is because with a larger number of zygotes being formed, there is a higher chance of different combinations of gametes coming together.
For example, let's say there are 10 gametes available: A, B, C, D, E, F, G, H, I, and J. If two gametes are chosen randomly to form a zygote, the possible combinations could be AB, CD, EF, GH, or IJ.
As the number of zygotes increases, the chance of different combinations occurring also increases. This can lead to a greater variety of genetic traits within the population.
Additionally, as the number of zygotes increases, the overall population size may also increase.
If each zygote develops into a fully grown individual, then with a larger number of zygotes, there will be a larger number of offspring.
To summarize, as the number of zygotes increases, the genetic diversity within the population may increase, and the overall population size may also increase.

A ∩ B ≠ ∅, A ∩ C = ∅
B ∈ C, A ∈ D
A ⊆ D,B ⊂ D
A ⊆ N,B ⊆ N
i. Write the sets out explicitly in terms of the elements, i. E. , do not write "A", "B" as members of any of the sets.
ii. After writing the sets out, show that each of the conditions are satisfied with brief explanations where appropriate.
the sets A, B, C, and D defined above satisfy all the given conditions.
Here's an example of four non-empty sets, A, B, C, and D, that satisfy the given conditions:
A = {1, 2, 3}
B = {2, 3, 4}
C = {B}
D = {A, B}
Now, let's verify that each condition is satisfied:
1. A ∩ B ≠ ∅: The intersection of sets A and B is {2, 3}, which is not empty. So, A ∩ B ≠ ∅ is true.
2. A ∩ C = ∅: The intersection of sets A and C is {B}, which is not empty. Therefore, A ∩ C = ∅ is not satisfied.
3. B ∈ C: Set B is indeed an element of set C. So, B ∈ C is true.
4. A ∈ D: Set A is an element of set D. Hence, A ∈ D is true.
5. A ⊆ D: Every element of set A is also an element of set D. So, A ⊆ D is true.

to show that two sides of one triangle are proportional to two corresponding sides of another triangle, with the included corresponding angles being congruent.
To show that two sides of one triangle are proportional to two corresponding sides of another triangle, with the included corresponding angles being congruent, you can use the Side-Side-Side (SSS) similarity criterion.
The SSS similarity criterion states that if the corresponding sides of two triangles are proportional and their corresponding angles are congruent, then the triangles are similar.
To prove this, follow these steps:
1. Given two triangles, let's call them triangle ABC and triangle DEF.
2. Identify two corresponding sides in each triangle that you want to show are proportional. Let's say AB and DE.
3. Also, identify the corresponding included angles, which are the angles formed by the corresponding sides. Let's say angle BAC and angle EDF.
4. Using the given information, state that AB/DE = BC/EF.
5. Now, prove that angle BAC = angle EDF. You can do this by showing that the two angles have the same measure or that they are congruent.
6. Once you have established that AB/DE = BC/EF and angle BAC = angle EDF, you can conclude that triangle ABC is similar to triangle DEF using the SSS similarity criterion.

Consider the function. (a) Decompose the function in the form y = f(u) and u = g(x). (Use non-identity functions for f(u) and u.) {Flu), u} = {C } (b) Find Y, as a function of x.
To rewrite the function in the chain rule form, we need to find two functions f(u) and g(x) such that y = f(u) and u = g(x). The function u(x) represents the inner function, while the function f(u) represents the outer function.
Once we have found f(u) and g(x), we can use the chain rule to find the derivative of y with respect to x, which will give us Y as a function of x. The chain rule tells us that the derivative of a composite function is equal to the derivative of the outer function evaluated at the inner function times the derivative of the inner function with respect to x.
Since {f(u), u} = {C}, we can take f(u) = C/u and u = g(x) = x^2. Thus, y = f(u) = C/x^2.
To find Y, we substitute x = 2t into the expression for y, which gives us:
Y = C/(2t)^2 = C/4t^2
Therefore, Y = C/4x^2.

let a be a 4 × 3 matrix, and let b and c be two vectors in r4. we are told that the system ax = b has a unique solution. what can you say about the number of solutions of the system ax = c?
The number of solutions of the system Ax = c is one, meaning it has a unique solution.
Let's discuss it further below.
Since the system Ax = b has a unique solution, this implies that matrix A has a rank of 3 (full column rank). Given that A is a 4x3 matrix and b and c are vectors in R4, we know that the system Ax = c also has a 4x3 matrix A and a vector c in R4.
Since A has full column rank, it means that the columns of A are linearly independent and the column space of A spans R3. This ensures that for any vector c in R4, the system Ax = c will also have a unique solution.
In conclusion, the number of solutions of the system Ax = c is one, meaning it has a unique solution.

Which property is illustrated?
x=y so 4x=4y
A) Associative property of multiplication
B) Distributive property of equality
C) Symmetric property of equality
D) Multiplication property of equality
E) Commutative property of multiplication
Answer: Commutative Property of multiplication
Step-by-step explanation:
The property illustrated in the given statement "x=y so 4x=4y" is: Multiplication property of equality. Correct option is D.
The Multiplication Property of Equality states that if you have an equation, and you multiply both sides of the equation by the same non-zero number, the resulting equation remains true.
In the given statement "x=y," it means that x and y are equal. Now, if you multiply both sides of this equation by the non-zero number 4, you get:
4x = 4y
The relationship between x and y hasn't changed because you're multiplying both sides of the equation by the same number (4). This is a direct application of the Multiplication Property of Equality. It maintains the equality between the quantities involved.
So, the statement "x=y so 4x=4y" illustrates the Multiplication Property of Equality because it shows that if two quantities are equal (x=y), then multiplying both sides by the same non-zero number (4) preserves that equality (4x=4y).

The measure of angle QOB is 75°.
What is right angle?
90 degrees is the angle of a right.
The right angle is created when two straight lines cross at a 90° angle or when they are perpendicular at the intersection. The symbol stands for a right angle.
Given:
Point O is the incenter of triangle ABC.
Lines are drawn from the points of the triangle to point O.
Lines are drawn from point O to the sides of the triangle to form right angles and line segments OQ, OR, and OS.
Angle OBC is 15 degrees. Angle OCR is 30 degrees.
OBC= 15

In OBQ
OBQ + QOB + OQB = 180
OBQ= OBC=15
OQB= 90
So,
QOB = 180- OBQ- OQB

Answer:
The temperature is: 14.5 degrees
Step-by-step explanation:
Given
\(T = 4 \cos(30(t - 8)) + 16\)
Required
The temperature at 4:15
We have:
\(t = 4:15\)
Convert to hours
\(t = 4+\frac{15}{60}\)
\(t = 4+0.25\)
\(t = 4.25\)
So:
\(T = 4 \cos(30(t - 8)) + 16\)
\(T = 4 \cos(30(4.25 - 8)) + 16\)
\(T = 4 \cos(30(-3.75)) + 16\)
Open bracket
\(T = 4 \cos(-112.5) + 16\)
\(T = 4 *-0.3826 + 16\)
\(T = -1.5304 + 16\)
\(T = 14.4696\)

Find the probability a student drives,
given that they are a senior.
P(drive | senior) = [?]
Round to the nearest hundredth
The probability that a student drives to school, given that they are a senior, is approximately 0.71, rounded to the nearest hundredth.
How to find the Probability?
We can use Bayes' theorem to find the probability that a senior student drives to school, given that they are a senior.
First, we need to calculate the probability of a student being a senior:
\(P(senior) = \frac{25+5+5}{(2+25+3+13+20+2+25+5+5)} = \frac{35}{100} = 0.35\)
Next, we need to calculate the probability of a senior student driving to school:
P(drive ∩ senior) = 25/100 = 0.25
Now we can apply Bayes' theorem:
P(drive | senior) = P(drive ∩ senior) / P(senior)
P(drive | senior) = 0.25 / 0.35 ≈ 0.71
Therefore, the probability that a student drives to school, given that they are a senior, is approximately 0.71, rounded to the nearest hundredth.

In a group of 40 pupils, 15 play the flute only. 7 play the piano only. 5 play both instruments. A student is chosen at random. What is the probability the student plays neither instrument?
Answer:
13/40
Step-by-step explanation:
Total No of pupils = 40
No of pupils who play the flute = 15
No of pupils who play the Piano = 7
No of pupils who play both = 5
Total No of pupils who can play the atleast one instrument = 15+5+7= 27
No one pupils who play neither instrument = 40 - 27 = 13
Probability of a pupil being chosen at random who plays neither instrument = No of Pupils who play neither instrument/ Total No of pupils = 13/40
