Suppose the volume of a cylinder is 169.65 ft cubes and the height is twice the radius what is the radius of the cylinder.
Answer:
The radius of the cylinder is [tex]r=3\ ft[/tex]
Step-by-step explanation:
we know that
The volume of the cylinder is equal to
[tex]V=\pi r^{2} h[/tex]
we have
[tex]V=169.65\ ft^{3}[/tex]
[tex]h=2r\ ft[/tex]

which best compares the pair of intersecting rays with the angle
A. The rays and angle have two end points.
B. The rays have a number of points lying on them, and the angle has only one point lying on it.
C. The rays extend infinitely, and the angle is made by rays which have a common endpoint
D. The rays and the angle have their lines extending in opposite directions
Answer:
C)The rays extend infinitely, and the angle is made by rays which have a common endpoint
Step-by-step explanation:
A ray is a line segment having one end point while extending in the other/opposite direction
An angle is made by two lines(rays) with common end point (vertex)
So when an angle is formed by the pair of intersecting rays the following options are ruled out
A) rays cannot have two end points
B) As rays extends infinitely in one direction, so having number of points is wrong
D)angles do not have lines
the following is best explanation is C
The rays extend infinitely, and the angle is made by rays which have a common endpoint !
Answer:
I'm pretty sure that the answer is C. The rays extend infinitely, and the angle is made by rays which have a common endpoint! It seems like the most correct answer of them all!

Step-by-step explanation:
three vertices of a rectangle are located at (5,3), (7,1), and (1,-1). what are the coordinates of the fourth vertex?
I first plotted the three points and from from their position it was clear which pairs to join to start a rectangle.
At this point you need to check to make sure the angle at B is a right angle. Find the slope of the line segments AB and BC and check that the product of the slopes is -1.
From the diagram you can now see where the fourth point D has to be. If AB and CD are parallel then D must be 3 units to the left of C and 2 units above C. Find the coordinates of D and then check by finding the slopes of CD and DA and showing that the angle at D is a right angle.

Answer:
12.00, 37.70
Step-by-step explanation:
Area of a circle is:
A = πr²
We know A = 113.1 ft², so:
113.1 = πr²
r² = 36.00
r = 6.00
The diameter is double the radius, so:
d = 2r
d = 12.00
The diameter is 12 feet.
The circumference is:
C = 2πr
We found that r = 6 ft, so:
C = 2π (6)
C = 37.70
The circumference is 37.70 ft.

The area of a parallelogram is 216 cm². The height of the parallelogram is 2/3 of its base. Find the base and height.
Final answer:
The problem involves finding the base 'b' and height 'h' of a parallelogram with an area of 216 cm², where the height is 2/3 of the base. By substituting h = (2/3)b into the area formula, base x height, and solving, we find that the base is 18 cm and the height is 12 cm.
Explanation:
To find the base and height of the parallelogram given that the area is 216 cm² and the height is 2/3 of its base, we use the formula for the area of a parallelogram:
Base x Height = Area of parallelogram
Let the base be 'b' and the height be 'h'. According to the problem, h = (2/3)b, so we can substitute 'h' in the area
formula:
b x (2/3)b = 216 cm²
Which simplifies to:
(2/3)b² = 216 cm²
Now, solve for 'b' to find the base, and use that to find 'h' (the height):
b² = (216 cm²) x (3/2)
b² = 324 cm²
b = √(324 cm²)
b = 18 cm
Therefore, the base is 18 cm. Now we find the height:
h = (2/3) x 18 cm
h = 12 cm
The base of the parallelogram is 18 cm and the height is 12 cm.
There are 10 fish tanks at a pet store. The data shows the number of fish in each tank. 30,32,41,38,42,30,35,38,40,45. Create a histogram of this data.
The histogram displays the distribution of fish counts in 10 tanks, ranging from 30 to 45 fish, with varying frequencies in each interval.
To create a histogram of the given data showing the number of fish in each tank, we'll first need to organize the data into intervals or bins and then count the frequency of fish counts falling within each interval. Here's how we can do it:
1. Determine the intervals or bins to represent the range of fish counts.
2. Count the frequency of fish counts falling within each interval.
3. Draw the histogram with the intervals on the x-axis and the frequency of fish counts on the y-axis.
Given the data: 30, 32, 41, 38, 42, 30, 35, 38, 40, 45
Let's choose intervals of width 5 starting from 25 to 50. Then, we count how many fish counts fall within each interval:
Interval 25-29: 0
Interval 30-34: 3 (30, 32, 30)
Interval 35-39: 3 (38, 35, 38)
Interval 40-44: 3 (41, 42, 40)
Interval 45-49: 1 (45)
Now, we can draw the histogram:
```
Frequency
| *
| * *
| * * * *
| * * * *
|_____________________
25 30 35 40 45

Each asterisk (*) represents one tank with the corresponding number of fish. The x-axis represents the intervals, and the y-axis represents the frequency of fish counts.
This histogram visually represents the distribution of fish counts in the 10 fish tanks at the pet store.

The function f(x) = –12x + 144,000 is used to model the number of granola bars in stock depending on the number of boxes, x, one machine packages if the machine starts with 144,000 granola bars. The mathematical range for the function is the set of real numbers.
Which statement describes the limitation for the reasonable range compared to the mathematical range?
The reasonable range is limited to the whole numbers when 0 ≤ y ≤ 12,000.
The reasonable range is limited to the rational numbers when 0 ≤ y ≤ 12,000.
The reasonable range is limited to the whole numbers when 0 ≤ y ≤ 144,000.
The reasonable range is limited to the rational numbers when 0 ≤ y ≤ 144,000.
Answer:
The reasonable range is limited to the whole numbers when 0 ≤ y ≤ 144,000.
Step-by-step explanation:
Notice that even though the range of the function is mathematically defined for all real numbers, in the real world you can't have more than 144,000 granola bars; that occurs when you have no boxes, or in other words, when x = 0
On the other hand, in the real word you can't have a negative quantity of a thing (you can't have minus 2 popsicles, for example). Given that granola bars are things, you must have at least 0 granola bars; in other words the quantity of granola bars must be greater or equal zero.
We know that in the real word you cant have more than 144,000 granola bars, and you must have at least 0 granola bars; therefore, the reasonable range of the function f(x) = –12x + 144,000 is 0 ≤ y ≤ 144,000.
Since we are talking of full granola bars here, the range is limited to whole numbers (whole granola bars).
We can conclude that the correct answer is: The reasonable range is limited to the whole numbers when 0 ≤ y ≤ 144,000.
Final answer:
The accurate statement is: The reasonable range is limited to the whole numbers when 0 ≤ y ≤ 144,000.
Explanation:
The question asks to identify the limitation of the reasonable range compared to the mathematical range for a function modelling the stock of granola bars, f(x) = – 12x + 144,000, based on the number of boxes, x, packaged by a machine.
The mathematical range could theoretically be any real number, but practically, since we are counting discrete items (granola bars), the reasonable range should be limited to whole numbers reflecting the actual possible quantities of granola bars in stock.
Additionally, since the stock cannot be negative and is started with 144,000 granola bars, the stock can range only down to 0 but not below, thus making the reasonable range from 0 to 144,000.
Therefore, the accurate statement is: The reasonable range is limited to the whole numbers when 0 ≤ y ≤ 144,000.

Paul's car is 12 feet long. He is making a model of his car that is 1/7 the actual size. What is the length of the model?
Answer:
2 feet
Step-by-step explanation:
The model is the actual size. This means that for every 6 feet measured on the actual car, the model will span 1 foot.
Note that the model length is in the numerator and the actual length is in the denominator.
Thus, if the car is 12 feet long and L represents the length of the model, then write the ratio as .
Set the two ratios equal to each other to obtain the proportion below.
The length of the model is given below.
Therefore, the length of the model is feet.
The question is about scale conversion in mathematics. Given that Paul's full-sized car is 12 feet long and his model is 1/7th the size of the actual car, the length of the model car would be about 1.71 feet.
Explanation:The question involves a scale conversion in mathematics. If Paul's car is 12 feet long in real life, and his model is going to be 1/7th the size of the actual car, we need to determine the length of the model using this scaling factor.
To find out the length of the model, you multiply the actual length of the car by the scale factor, which in this case is 1/7. So, the calculation would be as follows:
12 feet (length of the car) * 1/7 (scale factor) = 1.71 feet (approx)
Therefore, the length of Paul's model car would be approximately 1.71 feet.

15,000 blue trout were released into the Meherrin River for a scientific study. The function, f(x) = 15,000( _ 9 8 ) x , represents the number of blue trout after x years. In 5 years, what happens to the population?
Final answer:
The population of 15,000 blue trout is expected to increase to approximately 36,621 individuals after 5 years using the given growth function.
Explanation:
The question asks what happens to the population of 15,000 blue trout released into the Meherrin River after 5 years, given the function f(x) = 15,000(9/8)^x. To find out the population after 5 years, we substitute x = 5 into the function. The calculation proceeds as follows:
f(5) = 15,000 * (9/8)^5= 15,000 * (2.44140625)= 36,621.09375Therefore, after 5 years, the blue trout population is expected to increase to approximately 36,621 individuals, assuming ideal conditions without factors like predation or disease significantly impacting the population.

an equation to find the number of seats that need to be added to the theater to accommodate all the people.
Hey There!
To find how many seats are needed to be added, you need to subtract 15,340 by 13,451. You need to find the difference between the seats you need and the seats you have. So...
15,340-13,451= 1,889
You need to add 1,889 more seats.
Hope This helped!
Godspeed,
SongBird
Answer:
The required equation is 13451 + x = 15340,
1,889 seats are needed.
Step-by-step explanation:
Given,
Original number of seats = 13,451,
Also, the number of people who needed to be seated = 15,340,
Let x seats were added,
So, the new number of seats = 13451 + x
Thus, 15,340 will get the seat,
If total seats = 15340
⇒ 13451 + x = 15340
Which is the required equation,
Subtract 13451 on both sides,
We get,
x = 1889
Hence, 1889 seats are needed to accommodate all the people.

So to make it easier, you can break the shape up in a smaller shape. So now it'll look like 2 big rectangles on each side with a small rectangle in the middle. Now you can find the area.
For the big rectangle on the left:
5 × 15 = 75
For the big rectangle on the right:
5 × 15 = 75
For the small rectangle in the middle:
It doesn't say what the length is but if you subtract 8 from 15, that's what the length will be.
15 - 8 = 7
L = 7
7 × 2 = 14
Now add all the areas up.
