Answer:
Step-by-step explanation:15 books in 3 boxes =
books per box
Final answer:
The unit rate of 18 books in 3 boxes is 6 books per box, which is obtained by dividing the total number of books by the total number of boxes.
Explanation:
To find the unit rate of books per box when you have 18 books in 3 boxes, you need to divide the total number of books by the total number of boxes. This is a simple division problem:
Write down the number of books and the number of boxes: 18 books, 3 boxes.Divide the number of books by the number of boxes: 18 \/ 3 = 6 books per box.So, the unit rate is 6 books per box.

The composite figure is made up of a triangular prism and a pyramid. The two solids have congruent bases. A triangular pyramid is stacked on top of a triangular prism. They both share a triangular base. The triangle has a height of 10 and a base length of 22. The height of the triangular prism is 25. The height of the pyramid is 19.5. What is the volume of the composite figure? 715 units3 2,035 units3 2,750 units3 3,465 units3
Answer:
the answer is 3465
Step-by-step explanation:
got it right on ed
The required volume of composite figure is 3465 cubic units. Option d is correct.
For composite figure made of triangular pyramid over triangular prism both as congruent base with dimension h = 10 and base =22.
Hight for both pyramid and prism is 19.5 and 25
Volume of composite figure is to be determine,
When two or more solid put together to form new solid is said to be composite figure.
Here,
Volume of a pyramid = 1/3(1/2 base x height of triangle base)*h of
Volume of a pyramid = 1/3*22*10/2*19.5 = 715 cubic units
Similarly, for triangular prism
Volume of a triangular prism= 22*10/2x 25 = 2750 cubic units
Total volume = volume of a triangular (pyramid + prism)
Total volume = 715+2750
Total volume = 3465 cubic units.
Thus the required volume of composite figure is 3465 cubic units.

Determine perimeter
Answer:
20cm
Step-by-step explanation:
7.2 + 7.2 + 2.8 + 2.8 = 20
Each side of the rectangle is equal to the side opposite from it. That means you have 2 sides of 7.2 cm and 2 sides of 2.8 cm.
To find perimeter, you add all the sides. So that's 7.2 + 7.2 + 2.8 + 2.8, which is 20 cm altogether.
An entertainment venue has a total advertising budget of $5 million per year. 30% of the budget is spent on social media and 25% is spent on traditional media. Within the traditional media spending, 15% is spent on print advertising, 50% is spent on TV
advertising and 3596 is spent on radio advertising. How much is spent on radio advertising?
Answer:
437,500
Step-by-step explanation:
The percentage value of amount of money spent on radio advertising is given by R = $ 437,500
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage change is the difference between the measured value and the true value , as a percentage of the true value
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Given data ,
Let the percentage value of amount of money spent on radio advertising be represented as R
Now , the total amount of revenue money = $ 50,00,000
The percentage of money spent on traditional media = 25 %
So , the amount of money spent on traditional media = percentage of money spent on traditional media x total amount of revenue money
On simplifying , we get
The amount of money spent on traditional media = ( 25/100 ) x 5000000
The amount of money spent on traditional media = $ 12,50,000
Now , the percentage of amount spent on radio advertising = 35 %
So , the amount of money spent on radio advertising = ( 35/100 ) x amount of money spent on traditional media
On simplifying , we get
The amount of money spent on radio advertising = ( 35/100 ) x 12,50,000
The amount of money spent on radio advertising = $ 4,37,500
Hence , the amount of money on radio advertising is $ 4,37,500

If the scale factor for the dilation shown is 3 which is the length of B’ C’

Answer:
It's 15
Step-by-step explanation:
Got it right
The measure of B'C' after the dilation of 3 is given by the equation BC = 15
What is Dilation?Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent
Given data ,
Let the triangle be represented as ABC
Now , the dilated triangle is represented as A'B'C'
The dilation factor d = 3
The measure of side AB = 4 units
The measure of side BC = 5 units
The measure of side AC = 3 units
Now , after the dilation of 3 , we get
The measure of side A'B' = 12 units
The measure of side B'C' = 15 units
The measure of side A'C' = 9 units
Hence , the measure of side B'C' is 15 units

On a map the scale is shown as 0.5 inches equaling 15 miles. If two towns
are 2.25 inches apart on the map, what is the distance in miles between
the towns?
Answer:
The distance in miles between the towns is 67.5.
Step-by-step explanation:
Given:
On a map the scale is shown as 0.5 inches equaling 15 miles.
If the distance are 2.25 inches apart on the map between the towns .
Now, to find the distance in miles between the towns.
The distance on the map between the towns = 2.25 inches.
Let the actual distance between the two towns be [tex]x.[/tex]
The scale of the map is 0.5 inches equaling 15 miles.
If, 0.5 is equivalent to 15 miles.
Thus, 2.25 is equivalent to [tex]x.[/tex]
Now, to solve using by cross multiplication method:
[tex]\frac{0.5}{15} =\frac{2.25}{x}[/tex]
By cross multiplying we get:
[tex]0.5x=33.75[/tex]
Dividing both sides by 0.5 we get:
[tex]x=67.5\ miles.[/tex]
The actual distance between the two towns = 67.5 miles.
Therefore, the distance in miles between the towns is 67.5.

C) Only one sample can be derived from the same population.
D) A measurable characteristic of a sample is called a parameter
The statement that's is true is B. A population includes all of the elements from a set of data.
It's should be noted that a population of a given set of numbers consists of all the numbers. During research, a sample is gotten from the entire population and everyone has a chance of being picked.
It should be noted that there are several samples that can be gotten from the population. Also, a measurable characteristic of a population is not referred to as a statistic.
In conclusion, the correct option is B.

The correct statement is B) A population includes all of the elements from a set of data. This is because a population refers to the totality of subjects we wish to study, whereas a sample is a subset from which we collect data. A statistic is a measure of a sample, and a parameter is a measure of a population.
The question pertains to statistical terminology, specifically the definitions of sample, statistic, population, and parameter. B) A population includes all of the elements from a set of data. This statement is TRUE. A population refers to the entire set of subjects or elements that we are interested in studying. The definition can be applied across various contexts, such as all students in a school, all the birds in a forest, or all the cars produced by a factory.
Conversely, a sample is a subset of the population from which data is actually collected. This is because it is often impractical or impossible to collect data from the entire population. A statistic is a characteristic of a sample, such as the mean or standard deviation, which provides an estimate of the corresponding population parameter. A parameter, therefore, is a characteristic that describes the entire population. For instance, if we calculate the average height of a sample of students from a school, that average is a statistic that estimates the average height of the entire school population—an example of a parameter.
Statement A is incorrect because a measurable characteristic of a population is called a parameter, not a statistic. Statement C is incorrect because multiple samples can be drawn from the same population. Statement D is incorrect because a measurable characteristic of a sample is called a statistic, not a parameter.
