The perimeter of the shape is 13π
The area of the shape is 48.125π square units
What are the perimeter and area of the shapes?The perimeter of the shape is calculated as follows:
The perimeter of shape = perimeter of the two semicircles of radius 2 + perimeter of the two semicircles of radius 4.5The perimeter of a semicircle = πr
The perimeter of shape = 2 * π * 2 + 2 * π * 4.5
The perimeter of shape = 13π
The area of the shape = area of the two semicircles of radius 2 + area of the two semicircles of radius 4.5 + area of the rectangle
Area of semicircle = πr²/2
The area of the shape = π * 2²/2 + π(4.5)²/2 + 4 * 9
The area of the shape = 48.125π square units

What is congruent triangles and its rules ?
When two triangles are congruent, their three sides and their three angles match precisely.
If there is a turn or a flip, the equal sides and angles might not be in the same place, but they are still present.
ASA rule stands for Angle-Side-Angle rule which means two angles and a side of both triangles are equal.

On a certain weekday, the rate at which vehicles cross a bridge is modeled by the differentiable function R for 0 ≤ t ≤ 12, where R(t) is measured in vehicles per hour and t is the number of hours since 7:00 a.m. (t = 0). Values of R(t) for selected values of t are given in the table above.
The approximate value of R'(5) is -716 vehicles per hour per hour.
To approximate Rʹ(5), we can use the formula for the average rate of change
Rʹ(5) ≈ (R(6) - R(4))/(6-4)
We use the values given in the table to get
R(6) = 3010 vehicles per hour
R(4) = 3442 vehicles per hour
Therefore, Rʹ(5) ≈ (3010 - 3442)/(6-4) = -716 vehicles per hour per hour.
So, the approximate rate of change of the rate at which vehicles cross the bridge at 5:00 a.m. is -716 vehicles per hour per hour. This means that the rate at which vehicles cross the bridge is decreasing at a rate of 716 vehicles per hour every hour around 5:00 a.m.

Let's go through the answer choices to see which are true, and which are false.
A. This is false. It is stated that "LMN is greater than 90 degrees", so this angle is obtuse. Acute angles are less than 90 degrees.B. This is true. See choice A above.C. This is false. We're told that "angle MNO is less than 90 degrees". That makes the angle acute. D. This is false. See choice C above. Right angles are 90 degrees exactly.

26. The graph shows a polynomial function f. Polynomial function g=x^2(6-x). Compare the maximum values and the end behavior of the functions f and g when x>0
The end behavior of the polynomial is, rises to the left and falls to the right.
What is end behavior of polynomial?
A polynomial function typically behaves at its end in the same way that its leading term, or the term with the largest exponent, does at its end.
Look at the leading term of the polynomial function to understand its end behavior. Given that the leading term has the highest power, its behavior will dominate the graph because it will grow much more quickly than the other terms as x gets very large or very small.
Consider, the given polynomial g(x) = x^2 (6 - x)
From the graph of the polynomial function we can see that the maximum point of the polynomial is at its vertex.
The vertex of the polynomial is (10, 90).
So this is the maximum value of the function is (10, 90).
Now to find the end behavior of the polynomial.
The degree of the polynomial is 3 and the leading coefficient of the polynomial is, -1.
By using: Odd degree and Negative leading coefficient the graph Rises to the left and falls to the right.
Hence, the end behavior of the polynomial is, rises to the left and falls to the right.

The volume of the pyramid is V = (1/3) (3²) (5) = 45 cm³ thus the rate at which the water level is rising when the water level is 3 cm is 45 cm³/sec.
What is volume?Volume is a measure of the amount of space that an object occupies or contains. It is measured in terms of cubic units, such as cubic metres or cubic centimetres. Volume is a three dimensional measure, which means it takes into account the length, width and height of an object.
The rate at which the water level is rising when the water level is 3 cm can be calculated using the formula for the volume of a pyramid. The formula for the volume of a pyramid is V = (1/3) bh², where b is the area of the base and h is the height. In this case, the base is a square with sides of length 3 cm and the height is 5 cm. Therefore, the volume of the pyramid is V = (1/3) (3²) (5) = 45 cm³.
Since the water is being filled at a constant rate of 45 cm³/sec, then the rate at which the water level is rising when the water level is 3 cm is 45 cm³/sec. This is because the water level is rising at the same rate at which the water is being filled, and since the water is being filled at a rate of 45 cm³/sec, the water level is also rising at the same rate. This is why the rate at which the water level is rising when the water level is 3 cm is 45 cm³/sec.

Answer:
$0.23 or D
Step-by-step explanation:
Edg :)
The cost of one teaspoon of basil is $0.23. Therefore, option D is the correct answer.
We need to find the cost of basil per teaspoon.
How to interpret the data table?Interpretation of the data table is as follows:
Identify the subject under study.Identify the variable(s) presented in the table.Identify the measuring unit used (frequencies, percentages, rates, etc.)Read the information presented in table cells.Let the cost of one teaspoon of basil be $x, oregano be $y and parsley be $z.
Now, x+2y+3z=1.06-----(1), x+y+2z=0.72-----(2) and 2x+2y+z=0.99-----(3)
Equation (1)-(2), we get
x+2y+3z-(x+y+2z)=1.06-0.72
⇒y+z=0.34-----(4)
⇒z=0.34-y
Substitute z=0.34-y in equation (3).
That is, 2x+2y+0.34-y=0.99
⇒2x+y+0.34=0.99
⇒2x+y=0.65---(5)
Substitute z=0.34-y in equation (2)
Equation (5)-(4), we get
x+y+2(0.34-y)=0.72
⇒x+y+0.68-2y=0.72
⇒x-y=0.04-----(6)
Add equations (5) and (6), and we get
2x+y+x-y=0.65+0.04
⇒3x=0.69
⇒x=0.23
Therefore, the cost of basil per teaspoon is $0.23.

1. Why is money better than a bartering system?
A People might not have items to trade.
B It helps people to agree on the value of something.
C People might lose track of their money.
D Both A and B
E Both B and C
The correct answer is D. Both A and B
Explanation:
Bartering is an economic system in which products are directly exchanged for other products. For example, a pound of oranges is exchanged for a pound of rice. Due to this, in bartering, there is no money or elements such as coins or bills that represent the value of products or services. This system has both advantages and disadvantages in comparison to the use of money.
In terms of disadvantages, bartering implies individuals need products or services they can use to exchange, which might not be possible for all individuals as not all individuals might produce a product or have a product other are interested in. Also, in bartering the value of products varies, for example, a pound of blueberries can be equal to a pound of rice, three pounds of rice, or even half pound of rice, as values change according to the situation of those participating in the exchange. This means, in bartering the value fluctuates and it is more difficult to agree on the value of something, which does not occur if money is used as each product has a defined price which might just vary slightly. According to this, options A and B are advantages of money over bartering.
For Mean = 73.19, Mode = 79.56 and Variance = 16, the Karl Pearson's Coefficient of Skewness will be -0.0256 -1.64 0.0256 0
Answer:
To calculate Karl Pearson's coefficient of skewness, we need to use the formula:
Skewness = 3 * (Mean - Mode) / Standard Deviation
Given the Mean = 73.19, Mode = 79.56, and Variance = 16, we need to find the Standard Deviation first.
Standard Deviation = √Variance = √16 = 4
Now we can substitute the values into the formula:
Skewness = 3 * (73.19 - 79.56) / 4
Skewness = -6.37 / 4
Skewness = -1.5925
Rounded to four decimal places, the Karl Pearson's coefficient of skewness for the given values is approximately -1.5925.
