Step-by-step explanation:
Divide the circumference by pi to get diameter, which is 14. Divide 14 by 2 for the radius, which is 7. Now square the radius to get 49, and multiply by pi for the area.
Area is 49pi.
The area of the circle in terms of π with a circumference of 14π is 49π units².
Given a circle.
Also, given that:
Circumference of the circle = 14π
It is required to find the area of the circle.
It is known that:
Circumference of a circle is:
C = 2πr, where r is the radius.
So, here,
2πr = 14π
2r = 14
r = 7
So, the radius of the circle is 7.
So, the area of the circle is:
A = πr²
= π(7)²
= 49π
Hence, the area is 49π.

$930, $1620, $1245, $1581
$942, $1593, $1220, $980
$1260, $925, $1676, $1095
Answer: The correct answer is the third choice.
Step-by-step explanation: In order to solve this problem you need to calculate the range of each of the options presented. In order to do this you need to calculate the difference between the highest number and the lowest number. In the third option the lowest number is $942 and the highest number is $1,593. $1,593 - $942 = $651.
The prices my friend found are $942, $1593, $1220, $980.
What is range?Range is the difference between the highest and lowest values of a set of observations. Range is a measure of variation.
Range = highest value - lowest value
Which could be the set of prices?In order to determine the prices found, we have to determine the range of each option.

Call the number of hardcover and paperback books, h and p.
Thus
h + p = 8 and the value equation is
4h + 2p = 26
Now multiply the top one by four and subtract from the second one...we get
4h + 2p = 26
-(4h + 4p = 32)
----------------
-2p = -6
p = 3 so that
h = 5 x + y = 8, (1)
4x + 2y = 26, (2)
where x and y are the numbers of hardcover and softcover books respectively.
To solve, multiply the equation (1) by 2 (both sides) and then distract it from the equation (2). You will get
4x - 2x = 26 - 16, or
2x = 10, or x = 5 - the number of hardcover books purchased.
Then from the equation (1) you get y = 3.
Check. 4*x + 2*3 = 4*5 + 2*3 = 26. OK.

y=2x

The point X has the given coordinates (-3 1/2, 2).
How do we read a graph in the Coordinate (x-y) plane?A point on the graph can be read as a point (x, y) where y is the perpendicular distance of the point from the x-axis and x is the perpendicular distance of the point from the y-axis.
If the point is left to the y-axis, we take the distance negative.
If the point is below the x-axis, we take the distance negative.
How do we solve the given question?We are asked which point in the graph represents the point (- 3 1/2, 2).
To answer the question, we will analyze all the points to determine their coordinates.
Point W:
The perpendicular distance from the y-axis (x) = 2 units.
The perpendicular distance from the x-axis (y) = 3 1/2 units.
∴ The point W is (2, 3 1/2).
Point X:
The perpendicular distance from the y-axis (x) = 3 1/2 units.
The perpendicular distance from the x-axis (y) = 2 units.
∵ The perpendicular distance from the y-axis (x) is on the left side of the y-axis, we take x = 3 1/2 as negative, that is, x = -3 1/2.
∴ The point X is (-3 1/2, 2).
Point Y:
The perpendicular distance from the y-axis (x) = 2 units.
The perpendicular distance from the x-axis (y) = 3 units.
∵ The perpendicular distance from the y-axis (x) is on the left side of the y-axis, we take x = 2 as negative, that is, x = -2.
∵ The perpendicular distance from the x-axis (y) is below the x-axis, we take y = 3 as negative, that is, y = -3.
∴ The point Y is (-2, -3).
Point Z:
The perpendicular distance from the y-axis (x) = 2 units.
The perpendicular distance from the x-axis (y) = 3 units.
∵ The perpendicular distance from the x-axis (y) is below the x-axis, we take y = 3 as negative, that is, y = -3.
∴ The point Z is (2, -3).
∴ We can say that point X has the given coordinates (-3 1/2, 2).

what is the valume of that?
Answer:
960 in^3
Step-by-step explanation:
Multiply the base by the height
Base: (12*8)/2=48
Height: 20
The volume of a triangular prism is the area of the base multiplied by the height.
Let's first identify our values:
20 in = height of prism
12 in = base of triangle
8 in = height of triangle
First, we need to calculate the area of the triangle. To calculate the area of the triangle, we multiply the base of the triangle by the height of the triangle. In this case, the base is 12 and the height is 8 so 12 × 8 = 96 and then we divide 96 by 2 and we will get a quotient of 48.
Finally, we will multiply the area of the triangle which is 48 by 20.
48 × 20 = 960[tex]in^{2}[/tex].

What is the approximate area of the shaded region
ANSWER
The correct answer is
21.5 square centimeters
EXPLANATION
The shaded area is the area of the square minus the area of the Circle.
Area of shaded region
[tex] = {l}^{2} - \pi \: {r}^{2} [/tex]
From the diagram,
[tex]l = 10cm[/tex]
and
[tex]r = \frac{l}{2} = \frac{10}{2} = 5cm[/tex]
This implies that,
Area of shaded region
[tex] = {10}^{2} - \pi \times {5}^{2} [/tex]
[tex] = 100 -25 \pi [/tex]
[tex] \approx21.5 {cm}^{2} [/tex]
The answer would be 21.5 square centimeters. Hope this helps!

Answer:
D
Step-by-step explanation:
Since the ordered pairs are linear then the slope m between corresponding points will be equal.
To calculate m use the slope formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (6, 7) and (x₂, y₂ ) = (2, 5)
m = [tex]\frac{5-7}{2-6}[/tex] = [tex]\frac{-2}{-4}[/tex] = [tex]\frac{1}{2}[/tex]
Repeat with (x₁, y₁ ) = (6, 7) and (x₂, y₂ ) = (k, 11)
m = [tex]\frac{11-7}{k-6}[/tex] = [tex]\frac{1}{2}[/tex], that is
[tex]\frac{4}{k-6}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
k - 6 = 8 ( add 6 to both sides )
k = 14 → D

what is the spread of the middle 50% of the data called
the spread of the middle data is called the interquartile range and the left and right twenty five percent data are both called the twenty five percent quartiles
HOPE THIS HELPS
The Interquartile Range (IQR) is the spread of the middle 50% of data. It is found by subtracting the first quartile (Q1) from the third quartile (Q3). A larger IQR indicates more variability within the dataset.
Explanation:Interquartile Range (IQR)
The spread of the middle 50% of data in a dataset is known as the Interquartile Range (IQR). It is a measure of statistical dispersion and part of the five-number summary commonly used in descriptive statistics. To calculate it, you subtract the first quartile value (Q1) from the third quartile value (Q3). This range covers the middle 50 percent of the data, indicating where the bulk of the values fall and providing a sense of variability. An example based on given data can illustrate where Q1 is at 64.5 and Q3 is at 70, thus the IQR is 70 - 64.5 = 5.5. A larger IQR indicates more variability within the middle portion of the dataset. It is used alongside other descriptive statistics like the median, range, and standard deviation to provide a comprehensive understanding of the data's distribution.
Approximately what portion of the beaker is filled?
I would say the answer is A
To find the portion of the beaker filled, consider the total volume of the beaker and the volume up to which it is filled. Perform division and multiply by 100 to get the percentage filled.
Explanation:To determine the portion of the beaker filled, one must first understand the metrics of a beaker. A beaker is a cylindrical container with a flat bottom used to measure liquids. The scale etched on the side of the beaker represents the volume it contains. Suppose the total volume from the bottom up to the line of liquid is 300 mL and the total capacity of the beaker is 500 mL. By performing a simple division, 300 mL divided by 500 mL=0.6. Therefore, approximately 60% of the beaker would be filled. This is an approximate measure and for more accuracy, one should use a graduated cylinder.

If a circle has a diameter of 16 feet which expression gives its area in square feet
Answer: [tex] (8)^2\pi\ feet^2[/tex]
or
[tex]64\pi \ feet ^2[/tex]
Step-by-step explanation:
We are given that the diameter of a circle = 16 feet
Then the radius of the circle = [tex]r=\dfrac{d}{2}=\dfrac{16}{2}=\ 8 feet[/tex]
Also, the area of a circle is given by :_
[tex]A=\pi r^2[/tex] , where r is radius of the circle .
For r = 8 feet
The area of the circle = [tex]\pi (8)^2=\pi (64)=64\pi \ feet ^2[/tex]
Hence, the expression that gives its area in square feet =
[tex] (8)^2\pi \ feet^2[/tex]
or
[tex]64\pi \ feet ^2[/tex]

Answer:
x=12
Step-by-step explanation:
Let's solve your equation step-by-step.
3x−x+3+x−5−x=x+10
Step 1: Simplify both sides of the equation.
3x−x+3+x−5−x=x+10
3x+−x+3+x+−5+−x=x+10
(3x+−x+x+−x)+(3+−5)=x+10(Combine Like Terms)
2x+−2=x+10
2x−2=x+10
Step 2: Subtract x from both sides.
2x−2−x=x+10−x
x−2=10
Step 3: Add 2 to both sides.
x−2+2=10+2
x=12
Answer:
x= 12
Step-by-step explanation:
Cancel xx on both sides.
3x-x+3-5-x=103x−x+3−5−x=10
3x-x+3-5-x3x−x+3−5−x to x-2x−2.
x-2=10x−2=10
