what is the length of line segment ab
Answer:
The length of line segment is 13 units
Step-by-step explanation:
Given the line segment AB.
we have to find the length of line segment.
The coordinates of A and B are (0, 12) and (5, 0) respectively.
By distance formula,
[tex]\text{The distance between the points }A(x_1,y_1)\text{ and } B(x_2, y_2)[/tex]
[tex]AB=\sqrt{(x_2-x_1)^2+y_2-y_1)^2}[/tex]
[tex]AB=\sqrt{(5-0)^2+(0-12)^2}[/tex]
[tex]AB=\sqrt{25+144}=\sqrt{169}=13 units[/tex]
Hence, the length of line segment is 13 units.

A right circular cylinder has a height of 19 3/4 ft and a diameter 1 2/5 times its height.
What is the volume of the cylinder?
Enter your answer in the box. Use 3.14 for pi and round only your final answer to the nearest hundredth.
Height of cylinder = [tex] 19\frac{3}{4} =19.75 [/tex]ft
Diameter of cylinder = [tex] 1\frac{2}{5} [/tex]times its height = [tex] 1.4 * 19.75=27.65 [/tex]ft
Now Radius = half of diameter = [tex] \frac{27.65}{2} =13.825 [/tex]ft
Now we have to find the Volume of cylinder
formula for Volume of cylinder is
Volume of cylinder = [tex] \pi r^2 h [/tex]
let's plug the values
Volume of cylinder = [tex] (3.14)*(13.825)^2 *(19.75) [/tex]
Plug the values in calculator
= 11852.9657 cubic feet
Round off the answer to two decimal places(i.e. hundredth)
= 11852.97 cubic feet

A family reunion of 27 decided to go to Six Flags Magic Mountain. Adult tickets cost $40 each and child tickets cost $30 each. The total cost of all tickets was $930. Use the SUBSTITUTION METHOD to determine how many adults and how many child tickets were purchased?
To solve the problem, set up a system of equations with 'a' representing the number of adult tickets and 'c' representing the number of child tickets. Use the substitution method to solve for the variables. The solution is 12 adult tickets and 15 child tickets.
Explanation:To solve this problem using the substitution method, we need to set up a system of equations. Let's use the variables 'a' to represent the number of adult tickets and 'c' to represent the number of child tickets.
The cost equation can be expressed as: 40a + 30c = 930. This equation represents the total cost of all the tickets.
The quantity equation can be expressed as: a + c = 27. This equation represents the total number of people attending the reunion.
We can solve this system of equations using the substitution method. Multiply the second equation by 30 to get 30a + 30c = 810. Now subtract this equation from the first equation: 40a + 30c - (30a + 30c) = 930 - 810. Simplifying, we get: 10a = 120. Divide both sides by 10 to get a = 12.
Now that we know the number of adult tickets, we can substitute this value back into one of the original equations to solve for the number of child tickets. Using the second equation, we have: 12 + c = 27. Subtracting 12 from both sides, we get c = 15.
Therefore, 12 adult tickets and 15 child tickets were purchased.
What is the arm span of a 74 inch tall person
Final answer:
The arm span of a person is typically about equal to their height; therefore, a 74 inch tall person is likely to have an arm span of approximately 74 inches.
Explanation:
The arm span of a 74-inch tall person can be estimated based on certain proportions. In general, a person's arm span is approximately equal to their height. This means that a 74-inch tall person would have an arm span close to 74 inches.
The arm span of a person is generally very close to their total height. Based on anatomical studies and the concept that human body proportions tend to be relatively consistent regardless of overall size, a person who is 74 inches tall is likely to have an arm span that is also approximately 74 inches. However, it is important to note that while this is a common correlation, individual variations do exist and a precise measurement would require actual measurement rather than estimation.

Which of the sets of ordered data represents this box-and-whisker plot?
65, 65, 70, 75, 80, 80, 85, 90, 95, 100
65, 70, 75, 80, 80, 85, 90, 95, 100
65, 65, 72.5, 70, 75, 80, 80, 85, 90, 100
65, 70, 75, 80, 85, 90, 95, 100
the calculated five-number summaries with the given box-and-whisker plot, the set of ordered data that matches the plot is: 65, 65, 72.5, 70, 75, 80, 80, 85, 90, 100
To determine which set of ordered data represents a given box-and-whisker plot, we need to understand how a box-and-whisker plot is constructed.
A box-and-whisker plot shows the distribution of a dataset by displaying the five-number summary: minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum. Here's how these values are calculated:
1. Arrange the data in ascending order.
2. Find the median (Q2), which is the middle value of the dataset.
3. Find the first quartile (Q1), which is the median of the lower half of the dataset (excluding the median itself).
4. Find the third quartile (Q3), which is the median of the upper half of the dataset (excluding the median itself).
5. Determine the minimum and maximum values.
Let's calculate the five-number summary for each set of ordered data:
1. For the dataset: 65, 65, 70, 75, 80, 80, 85, 90, 95, 100
- Minimum: 65
- Q1: 70
- Median: 80
- Q3: 90
- Maximum: 100
2. For the dataset: 65, 70, 75, 80, 80, 85, 90, 95, 100
- Minimum: 65
- Q1: 75
- Median: 80
- Q3: 90
- Maximum: 100
3. For the dataset: 65, 65, 72.5, 70, 75, 80, 80, 85, 90, 100
- Minimum: 65
- Q1: 70
- Median: 77.5 (average of 75 and 80)
- Q3: 85
- Maximum: 100
4. For the dataset: 65, 70, 75, 80, 85, 90, 95, 100
- Minimum: 65
- Q1: 72.5 (average of 70 and 75)
- Median: 82.5 (average of 80 and 85)
- Q3: 92.5 (average of 90 and 95)
- Maximum: 100
Comparing the calculated five-number summaries with the given box-and-whisker plot, the set of ordered data that matches the plot is: 65, 65, 72.5, 70, 75, 80, 80, 85, 90, 100.
Using the given points, determine the slope. (5,-6)and(2,15)
Owen settled on a price of $7,870 for a new car. The dealer had to add 4.5% sales tax to this price, but allowed a $1,200 trade-in for Owen's old car. Although not a universal practice, please add the sales tax to the price of the new car first and then deduct the trade- in value. If the dealer required a 15% down payment, calculate the amount of the purchase price that Owen financed.
To find the amount that Owen financed, we first calculate the sales tax, add it to the initial price, deduct the trade-in value, and then calculate the percent of the final price that Owen needs to finance.
Explanation:To solve the problem, we first need to calculate the total cost of the car by adding the sales tax to the original price. Sales tax is calculated as follows: $7,870 * 4.5/100 = $354.15. So, the total cost before the trade-in is $7,870 + $354.15 = $8,224.15.
Next, we deduct the trade-in value of the old car, which is $1,200. The price after trade-in is, therefore, $8,224.15 - $1,200 = $7,024.15.
Finally, the dealer requires a 15% down payment. The amount Owen needs to finance is therefore 85% of the final price (100% - 15% = 85%). The financed amount is: $7,024.15 * 85/100 = $5,970.53.
