Therefore , the solution of the given problem of volume comes out to be chocolate bar therefore has a 2940 cubic centimetre (cm3) capacity.
Describe volume.The volume of a three-dimensional item, which is measured in cubic units, describes how much room it occupies. Two instances of cubic units are the numbers cm3 as well as in3. But mass can be used to measure an object's dimensions. Typically, an object's weight is transformed into mass units like kilos or kilogrammes.
Here,
The length, breadth, and height of the rectangular, prism-shaped chocolate bar can be multiplied to determine its volume.
Size = 15 centimetres
Width = undefined
Size equals 2 centimetres (thickness)
To solve for the width, we can rearrange this algorithm as follows:
=> Area/Length = Width
We are aware that the necessary length is 15 centimetres and the necessary area is 1470 cm2, so:
=> width = 1470/15
=> 98 centimetres.
Now that we are aware of every aspect of the chocolate bar, we can calculate its volume:
=> Volume = Length * Width * Height
=> 15 cm x 98 cm x 2 cm = 2940 cm³
The chocolate bar therefore has a 2940 cubic centimetre (cm3) capacity.

simplify 3½-(2⅓×1¼)+⅗
Step-by-step explanation:
First, we need to perform the multiplication operation within the parentheses, following the order of operations:
2⅓ × 1¼ = (7/3) × (5/4) = 35/12
Now, we can substitute the values in the expression:
3½ - (2⅓ × 1¼) + ⅗ = 7/2 - 35/12 + 3/5
To add or subtract fractions with different denominators, we need to find a common denominator. The least common multiple of 2, 12, and 5 is 60, so we can rewrite the fractions with this denominator:
7/2 - 35/12 + 3/5 = (210/60) / (2/2) - (175/60) / (12/12) + (36/60) / (5/5)
Simplifying the fractions within the parentheses:
= 210/60 - 175/60 + 36/60
= 71/60
Therefore, 3½ - (2⅓ × 1¼) + ⅗ simplifies to 71/60.
For the graph below which of the following is a possible function for f?
The graph below shows a parabola, indicating that the possible function for f is a quadratic equation.
What is graph?Graph is a data structure consisting of nodes (vertices) and edges that connect them. Graphs are used to represent networks of data, such as social or computer networks. Graphs are also used to represent mathematical and logical equations, as well as to store and display data. Graphs are composed of two basic components: nodes (vertices) and edges (arcs). Nodes represent the objects in the network, while edges represent the connections between them. Graphs can be used to model many different types of relationships and can be used to solve a variety of problems in different areas, such as computer science, mathematics, engineering, and social sciences.
A quadratic equation is an equation of the form ax2 + bx + c = 0, where a, b and c are real numbers and a ≠ 0. This type of equation is important in mathematics, as it can represent many physical situations, such as a ball thrown into the air, or a spring that is stretched or compressed. Quadratic equations can be solved using the quadratic formula, which uses the coefficients a, b and c to calculate the two solutions for x. In the graph, the parabola has an equation of the form y = ax2 + bx + c, and so the possible function for f is a quadratic equation.

5. PLACE SETTINGS Kelly is designing how she
wants to put the place settings for her party. She wants
the tables to be set up symmetrically with the design
that is on the table. First she places plates shown.
a. What is the order and magnitude of the rotational
symmetry of the figure?
b. Make the least possible number of the additions of
plates to the figure so that the table has rotational
symmetry of order 4 around its center.
The figure has rotational symmetry of order 2 and to achieve rotational symmetry of order 4, three plates need to added.
Explain about symmetry?
Symmetry is a property of an object that describes how it appears identical after some transformation, such as reflection, rotation, or translation. It is an essential concept in mathematics, science, art, and many other fields.
There are several types of symmetry, including:
Reflectional symmetry (also called bilateral symmetry).
Rotational symmetry.
Translational symmetry.
According to the question:
a. The figure has rotational symmetry of order 2. This means that if we rotate the figure 180 degrees around its center, the figure will look exactly the same as it did before the rotation.
b. To achieve rotational symmetry of order 4, we need to add plates in such a way that the figure looks the same after a rotation of 90 degrees, 180 degrees, and 270 degrees around its center.
To achieve this, we can add three more plates to the figure, one in between each pair of existing plates, After adding these plates, the figure has rotational symmetry of order 4. We can see this by rotating the figure 90 degrees, 180 degrees, and 270 degrees around its center
so the figure has rotational symmetry of order 4. Therefore, we only needed to add three plates to the figure to achieve rotational symmetry of order 4 around its center.

If Colleen selected one egg, cracked it open and found out it was raw, the probability of selecting the hard-boiled egg on her second pick is 1/5. The probability of Colleen selecting the hard-boiled egg on her first try is 1/5. If Colleen selected one egg, cracked it open and found out it was raw, the probability of selecting the hard-boiled egg on her second pick is 1/6. The probability of Colleen selecting a raw egg on her first try is 1/6.
Answer: If Colleen selected one egg, cracked it open and found out it was raw, the probability of selecting the hard-boiled egg on her second pick is 1/5, and the probability of Colleen selecting the hard-boiled egg on her first try is 1/6.
To see why, let's consider the possible scenarios:
Colleen selects the hard-boiled egg on her first try. There is only 1 hard-boiled egg out of the 6, so the probability of this happening is 1/6.
Colleen selects a raw egg on her first try. There are 5 raw eggs out of the 6, so the probability of this happening is 5/6. After she cracks open the raw egg, there will be 4 raw eggs and 1 hard-boiled egg left. So the probability of selecting the hard-boiled egg on her second pick is 1/5.
Therefore, the statement "If Colleen selected one egg, cracked it open and found out it was raw, the probability of selecting the hard-boiled egg on her second pick is 1/5, and the probability of Colleen selecting the hard-boiled egg on her first try is 1/6" is true.

The graph shows the total cost c of buying one large bucket of popcorn and d large drinks. Write an equation from the graph that could be used to find the total cost c if you buy one large bucket of popcorn and d large drinks.
The equation of the line that represents the total cost is c = 4d + 8 and the total cost when 1 drink is bought is $ 12.
The slope-intercept form:The slope-intercept form of a line has used to form a linear equation in two variables. It is called the slope-intercept form because it gives us two pieces of information about the line its slope and y-intercept.
The slope-intercept form of a line is given by the equation:
y = mx + bwhere:
m is the slope of the line
b is the y-intercept of the line
Here we have
The graph shows the total cost c of buying one large bucket of popcorn and d large drinks.
From the graph, the line passes through points (0, 8) and (1, 12)
Hence, slope of the line (m) = [(y₂ - y₁) / (x₂ - x₁) ]
= [(12 - 8) / (1 - 0) ] = [4 / 1] = 4
Let y = mx + c be the lines
=> y = 4x + c
Since the line passes through (0, 8)
=> 8 = 4(0) + c
=> c = 8
Hence, the required equation is y = 4x + 8
From the data,
The y-axis represents the total cost 'c' and the x-axis represents the number of drinks 'd'
=> Total cost c = 4d + 8
Hence,
The equation of the line that represents the total cost is c = 4d + 8
If we bought 1 large drink
=> c = 4(1) + 8 = 12
Therefore,
The equation of the line that represents the total cost is c = 4d + 8 and the total cost when 1 drink is bought is $ 12.

Which conic section does the equation below describe? (x - 3)^2)/10 - (y + 5)^2)/9 = 4
Answer:
The given equation is of the form:
((x - h)^2)/a^2 - ((y - k)^2)/b^2 = 1
Comparing it with the given equation:
((x - 3)^2)/10 - ((y + 5)^2)/9 = 4
We can rewrite the equation in the standard form by dividing both sides by 4, then adding (y+5)^2/9 to both sides:
((x - 3)^2)/40 - ((y + 5)^2)/36 = 1
Now, we can see that the equation is in the standard form of a hyperbola. The center of the hyperbola is (3, -5), the distance between the center and each vertex is sqrt(10) in the x-direction and sqrt(9) in the y-direction, and the hyperbola opens to the left and right.
If 55% of a number is 121 and 75% of the same number is 165, find 20% of that number.
Answer:
20% of the number is 44.0.
Step-by-step explanation:
Let's say the number is "x".
We can start by setting up two equations based on the given information:
0.55x = 121
0.75x = 165
We can solve for x by dividing both sides of each equation by the coefficient of x:
x = 121/0.55 ≈ 220.0
x = 165/0.75 = 220.0
Now that we know the value of x, we can find 20% of it by multiplying it by 0.20:
0.20 * 220.0 = 44.0
Therefore, 20% of the number is 44.0.

I think this is what you sayed?
For the following:
a) The range of the heights is 26 cm.b) The amplitude of the heights is 2.6 cmc) The frequency table is attached.How to find range and frequency?a) To determine the range of the heights, find the difference between the highest and lowest values.
Range = Highest value - Lowest value
The highest value is 188 cm, and the lowest value is 162 cm.
Range = 188 - 162 = 26 cm
b) The amplitude is the interval width of each class in the frequency table. To determine the amplitude, Know the number of classes. Assume to create 10 classes for the height data.
Amplitude = Range / Number of classes
Amplitude = 26 cm / 10 = 2.6 cm
c) To build the frequency table, to create the class intervals for the height data. Since the amplitude is 2.6 cm, choose the class intervals accordingly.
Set up the frequency table with 10 classes:
Class Intervals: (160 - 162.6], (162.6 - 165.2], (165.2 - 167.8], ..., (185 - 187.6], (187.6 - 190]
Next, count the number of data points falling into each class interval and calculate the absolute frequency (frequency), cumulative frequency, relative frequency, and percentage relative frequency.
The frequency table for the height data is attached.
In the frequency table, the "Cumulative Frequency" column shows the running total of frequencies, the "Relative Frequency" column shows the proportion of each class frequency to the total number of data points (80), and the "Percentage Relative Frequency" column shows the relative frequency expressed as a percentage.

Suppose a population of 150 mice triples in size every 4 months. How many mice will there be after 3 years?
Therefore, if a population of 150 mice triples in size every four months, there will be approximately 2,952,450 mice in the neighbourhood in 3 years.
what is unitary method ?Mathematicians use the unitary method to answer proportional relationship problems involving two or more quantities. It entails calculating the worth of one unit of one quantity in relation to another. For instance, let's say we are aware that 3 pencils cost $6. The following is how we can calculate the price of a solitary pen using the unitary method: The value of a single entity of the quantity "pen cost" in terms of the quantity "number of pens" was determined in this case. Once we are aware of a unit's worth, we can use that knowledge to determine the value of any other quantity that is related to it.
given
The population triples, or grows three times, in number, after four months. As a result, if we commence with 150 mice, the population will look like this after 4 months:
150 × 3 = 450 mice
The populace will triple once more after another 4 months (or 8 months from the beginning), becoming:
450 × 3 = 1350 mice
The populace will triple once more after another 4 months (or 12 months from the beginning), becoming:
1350 × 3 = 4050 mice
There is a pattern here: every four months, the populace triples. Therefore, we can determine how many times the population triples after three years (or 36 months) have passed:
36 months divided by 4 months per triple equals 9 triples.
the following group will exist after three years:
2,952,450 mice are equal to 150 × 39 (150 x 19,683).
Therefore, if a population of 150 mice triples in size every four months, there will be approximately 2,952,450 mice in the neighbourhood in 3 years.
