2.1 Determine the number of faces the container has.(2)
If the container is closed rectangular it has six faces - a top, a bottom, and four rectangular sides. If the container has an opening, it has five faces - a top, a bottom, and four rectangular sides.
What is the number of faces of any geometry?The number of faces of any geometry can vary depending on its specific shape and design. In geometry, a face is a flat surface that forms part of the boundary of a solid object.
For example, a cube has six faces, a rectangular prism has six faces, and a sphere has no faces (because it is a curved surface with no edges or corners).
The number of faces in a container can vary depending on its shape and whether it has any openings. Here are some common types of containers and the number of faces they have:
Rectangular container: If the container is completely closed, it has six faces - a top, a bottom, and four rectangular sides. If the container has an opening, it has five faces - a top, a bottom, and four rectangular sides.
Circular container: If the container is completely closed, it has two faces - a top and a bottom. If the container has an opening, it has three faces - a top, a bottom, and a curved side.
Cylindrical container: If the container is completely closed, it has three faces - a top, a bottom, and a curved side. If the container has an opening, it has four faces - a top, a bottom, a curved side, and an additional flat side where the opening is located.

Therefore, the likelihood of a thunderstorm is roughly 0.2174, or a 21.74% chance that one will occur.
What is probability?The study of random events or phenomena falls under the category of probability, which is a branch of mathematics. It is a way to quantify the possibility or likelihood of an event happening. A number between 0 and 1, where 0 denotes an improbable occurrence and 1 denotes a certain event, is used to express probability. By dividing the number of favorable outcomes by the total number of possible outcomes, one can determine the probability of an occurrence. In many disciplines, including statistics, economics, engineering, and science, probability is used to make predictions and well-informed choices in uncertain situations.
given
We must divide the amount of beneficial outcomes (chances of a thunderstorm) by the total number of possible outcomes in order to express the suggested degree of likelihood as a probability value between 0 and 1 inclusive.
When the likelihood of a thunderstorm is stated as "5 in 23," it indicates that out of a possible 23, 5 outcomes are likely to be favorable.
Therefore, the likelihood of a rainstorm is:
P (thunderstorm) is the ratio of the number of successful outcomes to all other possible outcomes.
Thunderstorm P(thunder) = 5 / 23
As a result, the probability value for the indicated degree of likelihood can be expressed as:
P(thunderstorm)= 5/230.2174
Therefore, the likelihood of a thunderstorm is roughly 0.2174, or a 21.74% chance that one will occur.

Raju went to a shop and bought 4 books at the rate of Rs 222.75 each, and 2 books are sold at Rs. 14 each.
Answer:
Raju spent a total of Rs 919.50. He bought 4 books at Rs 222.75 each, which cost Rs 891, and 2 books at Rs 14 each, costing Rs 28.50
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let's first calculate the total cost of the 4 books that Raju bought:
Cost of 1 book = Rs 222.75
Cost of 4 books = 4 x Rs 222.75 = Rs 891
Now, let's calculate the amount of money Raju received by selling 2 books at Rs 14 each:
Amount received by selling 1 book = Rs 14
Amount received by selling 2 books = 2 x Rs 14 = Rs 28
Therefore, the total cost of 4 books is Rs 891 and the total amount received by selling 2 books is Rs 28. To find Raju's overall expenditure, we need to subtract the amount received from the total cost of 4 books:
Raju's overall expenditure = Total cost of 4 books - Amount received by selling 2 books
= Rs 891 - Rs 28
= Rs 863
Therefore, Raju's overall expenditure is Rs 863.

Show that T(u,v)=(u^2−v^2,2uv)T(u,v) maps the triangle ={(u,v):0≤v≤u≤1} to the domain D bounded by x=0, y=0, and y^2=4-4x. Use T to evaluate
The area of the image of the triangle under T is 5/9.
What is Triangle?
In geometry, a triangle is a closed two-dimensional shape with three straight sides and three angles. It is one of the basic shapes in geometry and is characterized by its three vertices (points where two sides intersect) and three sides (line segments that connect the vertices). The sum of the interior angles of a triangle is always 180 degrees, and the length of each side is less than the sum of the lengths of the other two sides.
To show that T maps the given triangle to the domain D, we need to find the image of the three vertices of the triangle under T and then show that the image lies inside D.
Let's first consider the vertex (0,0) of the triangle. Applying T, we get T(0,0) = (0,0). So the image of the vertex (0,0) is the origin, which clearly lies inside D.
Now let's consider the vertex (1,1) of the triangle. Applying T, we get T(1,1) = (0,2), which lies on the y-axis and satisfies y²=4-4x, so it lies inside D.
Finally, let's consider the vertex (u,0) of the triangle, where 0≤u≤1. Applying T, we get T(u,0) = (u²,0). This lies on the x-axis and satisfies y²=4-4x only when x=1, which is outside D. Therefore, the image of this vertex is not inside D.
Hence, we can conclude that T maps the triangle to the domain D, except for the line segment {(u,0):0≤u≤1}.
To evaluate the area of the image, we can use the fact that the area of the image of a region under a transformation is equal to the absolute value of the determinant of the Jacobian matrix of the transformation, multiplied by the area of the original region.
The Jacobian matrix of T is given by
J(T) = [2u -2v]
[2v 2u]
The absolute value of the determinant of this matrix is 4u² + 4v², so the area of the image of the triangle is
∫∫R 4u²+4v² dA,
where R is the region in the uv-plane corresponding to the triangle.
Integrating over R, we get
∫0 ∫v 4u²+4v² dudv
= ∫0 (4/3) (1-v³+3v²) dv
= (4/3) (1/4 - 1/16 + 1/3 - 1/12)
= 5/9.
Therefore, the area of the image of the triangle under T is 5/9.

In AABC, G is the centroid and DC = 36.
Find DG and GC. Help me please!
Answer:
DG = 12 , GC = 24
Step-by-step explanation:
DC is a median of Δ ABC
on each median the distance from the vertex to the centroid is twice as long as the distance from the centroid to the midpoint, that is
GC = 2 DG , then
DG + GC = DC , that is
DG + 2 DG = 36
3 DG = 36 ( divide both sides by 3 )
DG = 12
thus
DG = 12 and GC = 2 × 12 = 24
EXCERSIZE 2 Eastern Cape Sept V2 2013 Anver, who recently lost his job, decided to start his own rental car (taxi) business. Anver was paid a round sum of money of R400 000 from his previous employer. He used some of this money to pay a 15% deposit on a vehicle to the car dealer. After doing some research, he decided to buy a Toyota Quantum 2.5D-4D 14-seater passenger van. 1.1 r PH M'S Price: R392 900 Interest rate: Prime rate + 1% Term: 72 months
The answer of the question based on monthly installment is Anver's monthly installment is R6 253.27.
What is Formula?
In mathematics, formula is set of symbols or expressions representing mathematical relationship or the rule. Formulas are often used to describe and solve the problems in mathematics, science, engineering, and other fields.
To determine the amount of the loan, we can calculate 85% of the price of the van, which is the amount that Anver would have to borrow after paying the 15% deposit:
Amount of loan = 85% of R392 900
= 0.85 x R392 900
= R333 965
To determine the monthly installment, we need to use the formula for the present value of an annuity:
PV = PMT x (1 - (1 + r/n)^(-nt)) / (r/n)
We can calculate the annual interest rate by adding 1% to the prime rate. According to the South African Reserve Bank, the prime rate in September 2013 was 9%.
Annual interest rate = prime rate + 1%
= 9% + 1%
= 10%
Therefore, we can substitute the given values into the formula:
PV = R333 965
r = 10% / 12 = 0.8333%
n = 12
t = 72 / 12 = 6
Rearranging the formula to solve for PMT, we get:
PMT = PV x (r/n) / (1 - (1 + r/n)^(-nt))
Substituting the values, we get:
PMT = R6 253.27 (rounded to two decimal places)
Therefore, Anver's monthly installment is R6 253.27.

Part B: What is the least number of
days after Monday that Kelli needs
to run to reach her goal?
The inequality which represents the least number of days that Kelli needs to run to reach her goal is
2 1/4 + 1/3d ≥ 4.
The least number of days after Monday that Kelli needs to run to reach her goal is 5.25 days
Which inequality represents the least number of days that Kelli needs to run to reach her goal?Monday= 2 1/4 miles
Other days of the week = 1/3 miles
Her goal =™4 miles
Number of days = d
2 1/4 + 1/3d ≥ 4
subtract 2 1/4 from both sides
1/3d = 4 - 2 1/4
1/3d = 4 - 9/4
1/3d = 16-9 /4
1/3d = 7/4
divide both sides by 1/3
d = 7/4 ÷ 1/3
d = 7/4 × 3/1

A w ≤ 11
B w < 11
C w > 11
D w ≥ 11
Answer:
Lamar claims that the weight of her cat is "almost 11 pounds".
Since Lamar is using the word "almost", we can assume that she means the weight of her cat is very close to 11 pounds, but not exactly 11 pounds.
Therefore, we can represent Lamar's claim with the inequality:
B) w < 11
This is because if the weight of Lamar's cat is almost 11 pounds, but not exactly 11 pounds, then the weight must be less than 11 pounds.

On the Junior League baseball field, you run 60 feet to first base and then 60 feet to second base. You are out at second base and then run directly along the diagonal to home plate. Find the total distance that you ran. Round your answer to the nearest tenth.
Answer:
Step-by-step explanation:
We can use the Pythagorean theorem to find the distance from second base to home plate, which is the diagonal of a right triangle with legs of 60 feet each:
d = sqrt(60^2 + 60^2) = sqrt(7200) ≈ 84.85 feet
So the total distance that you ran is:
60 + 60 + 84.85 ≈ 204.9 feet
Rounded to the nearest tenth, the answer is:
204.9 feet ≈ 204.9 feet
How many more saplings with a height of 27 1/4 inches or less were there than saplings with a height greater than 27 1/4 inches?
(Total saplings- Saplings with a height greater than 27 1/4 inches) = Number of saplings with a height of 27 1/4 inches or less.
How to find height of an object?To find the height of an object in mathematics, you must first identify the shape of the object. Then, use the relevant formula for the shape to calculate the height. For example, if the object is a right triangle, the height can be found by using the Pythagorean Theorem. Additionally, if the object is a rectangle, you can use the formula for the area of a rectangle to calculate the height. Finally, if the object is a circle, you can use the formula for the circumference of a circle to find the height.
To solve this question, we will use the numerical approach. First, we need to subtract the number of saplings with a height greater than 27 1/4 inches from the total number of saplings. Then, we subtract the result from the total number of saplings. The result will be the number of saplings with a height of 27 1/4 inches or less.
Therefore, the equation is (Total saplings- Saplings with a height greater than 27 1/4 inches) = Number of saplings with a height of 27 1/4 inches or less.

find the inverse of each function
1. f(x) = 4/3x -7
2. (the picture above)
The inverse of the given functions are f⁻¹(x) = 3/4(x + 7) and f⁻¹(x) = x^2 + 10x + 25
What is the inverse of a function?The inverse of a function is a new function that undoes the effects of the original function.
In other words, if we have a function f(x) that maps x to y, then the inverse of f(x), denoted by f^-1(y), maps y back to x.
Given that:
f(x) = 4/3x - 7
Write as an equation
y = 4/3x - 7
Interchange the variables
x = 4/3y - 7
Solve for y
y = 3/4(x + 7)
Replace y with f⁻¹(x) to show the final answer.
f⁻¹(x) = 3/4(x + 7)
Also, the inverse of the function f(x) = √x -5 is computed as follows:
Interchange the variables and solve for y;
x = √y -5
y = x^2 + 10x +25
Replace y with f⁻¹(x) to show the final answer.
f⁻¹(x) = x^2 + 10x + 25

. Samuel used
because
Julie used direct proof because each statement is deduced from a previous statement. Samuel used indirect proof because the final statement contradicts the assumption.
What are direct and indirect proofs?
The complete question is given below.
Both Julie and Samuel are asked to prove m∠CBD = 65°.
Let us look at Julie's proof.
She used the known facts which are given and finally proved that m∠CBD = 65°. So Julie used direct proof.
Now let us observe Samuel's proof.
He started contradicting the statement when he wrote
m∠CBD + 65° ≠ 90°
So the last statement goes against what he was asked to prove.
Samuel used indirect proof.
Therefore Julie used direct proof because each statement is deduced from a previous statement. Samuel used indirect proof because the final statement contradicts the assumption.
