Answer:
[tex]144\pi[/tex]
Step-by-step explanation:
Circumference = [tex]\pi d[/tex]
Diameter = [tex]2r[/tex]
Area of a circle = [tex]\pi r^2[/tex]
From our first equation, we can find our value for our diameter:
We do this by dividing [tex]24 \pi[/tex] by [tex]\pi[/tex] to get 24.
[tex]c=\pi d[/tex]
[tex]d=\frac{c}{\pi } = \frac{24\pi }{\pi } =24[/tex]
Using our second equation, we can find out the value for our radius:
[tex]d=2r[/tex]
[tex]r=\frac{d}{2} =\frac{24}{2} =12[/tex]
Now we have a value for our radius, we can use our third equation to find out our area:
[tex]A=\pi 12 ^2 = 144 \pi[/tex]
Given that:
The circumference of a circle is 24π ft.To Find:
What is the area, in square feet?We know that:
Circumference of a circle = 2πRArea of a circle = πR²Where,
Radius is denoted as R.Finding the radius of the circle:
Circumference of a circle = 24π
⟶ 2πR = 24π
⟶ 2πR = 2π × 12
Cancelling 2π.
⟶ R = 12
∴ Radius of the circle = 12 ft.
Finding the area of the circle:
⟶ Area = πR²
⟶ Area = π(12)²
⟶ Area = π × 12 × 12
⟶ Area = π × 144
⟶ Area = 144π
Hence,
Area of the circle is 144π square feet.3/4+4/5+5/6=?

if rectangle a and rectangle b have a ratio of similarity of 5:4, what is the area of rectangle B if the area of the rectangle A is 24 square units
Answer:
the answer is 30 this is because if you rectangle b is 24 then rectangle a is 30 like if you simplify 30:25 if you divide it by 6 it will give 5:4
Step-by-step explanation:
Final answer:
The area of rectangle B is approximately 15.36 square units.
Explanation:
To find the area of rectangle B, we can use the ratio of similarity.
The ratio of similarity between rectangle A and rectangle B is 5:4.
Since the area of rectangle A is 24 square units, we can set up the equation:
(area of B) / (area of A) = (side length of B)² / (side length of A)².
Substituting the values, we get
(area of B) / 24 = (4/5)².
Solving for the area of B, we have
(area of B) = 24 * (4/5)²
= 24 * 16/25
= 384/25
= 15.36 square units.

To find the length of side a in a right triangle, we can use the Pythagorean theorem.
Explanation:To find the length of the side a, we can use the Pythagorean theorem. In a right triangle, the Pythagorean theorem states that the square of the length of the hypotenuse (h) is equal to the sum of the squares of the lengths of the other two sides (a and b). So, we have a² + b² = h². Rearranging the equation, we can solve for side a: a = sqrt(h² - b²). Plugging in the known values, we can calculate the value of side a.

Similarly for the 11th graders we have total pupils = 29 with 15 preferring English, therefore the number of the 11th graders that prefer math is 29 - 15 = 14 pupils
Also for the 10th graders we have total pupils = 26 with 18 preferring math, therefore the number of the 11th graders that prefer English is 26 - 18 = 8 pupils
Finally for the 9th graders, we have a total of 63 pupils with 40 preferring English, therefore the number of the 9th graders that prefer math is 63 - 40 = 23 pupils

A research group is trying to determine the correlation between the number of hours spent
studying and the number of hours sleeping. Use the data shown on the graph to compute
the correlation coefficient.
A) r = 1 C) r = − 1
B) r = 0.5 D) r = −0.5
Answer:
C) r = − 1Step-by-step explanation:
In the graph, you can observe that all five points are perfectly lined up on a straight line, which is decreasing, because each points is lower than the previous one.
This situation represents a coefficient of correlation of -1, which means there's a strong negative correlation between variable.
Once again, graphically, this strong negative correlation can be deduct from the behaviour of the data, which is clearly decreasing with a straight line behaviour. In other words, the line that best fits is almost unique.
Therefore, the right answer is C.
Answer: C

find the exact length of the third side
Answer: 3 times the square root of 5! (Or the square root of 45 if you don’t want to simplify)
Step-by-step explanation:
First, you would need to use the Pythagorean Theorum, a^2 + b^2 = c^2, since it is a right triangle.
So in this case,
6^2 + 3^2 = c^2
This simplfys to:
36 + 9 = c^2
45 = c^2
Now you have to take out the square in the c. What you do to one side, you have to do to the other, so you have to put 45 in a square root. This simplies to 3 times the square root of 5.

width of the viewing area?
Answer: 15 inches wide
Step-by-step explanation:
to find the area of a rectangle you would multiply the height by the width so this would be the opposite because we have the area which is 135 in.² so we would divide 135 by 9 which would give us 15.

Solving systems of equations algebraically.
6x + 8y = -22
y = -5
And SHOW YOUR WORK!!!!
Answer:
x = 3
y = -5
Step-by-step explanation:
Since you have the value of y already, just plug it into the equation, like so:
6x + 8y = -22
6x + 8(-5) = -22
6x - 40 = -22
Add 40 to both sides:
6x - 40 = -22
+ 40 + 40
___________
6x = 18
Finally, divide both sides by 6:
6x = 18
x = 3
So now you have, x = 3 and y = -5.
Brian scored an 80% on a Chemistry Exam. The average on the exam was a 68%, with a standard deviation of
5%. What is Brian's z-score?
Answer:
Brian's z-score is 2.4
Step-by-step explanation:
The equation for z score is presented as follows;
[tex]z = \frac{x- \mu}{\sigma}[/tex]
Where:
x = Score = 80%
μ = Mean = 68%
σ = Standard deviation = 5%
Plugging in the values gives;
[tex]z = \frac{80- 68}{5} =2.4[/tex]
Therefore, Brian's z-score on the Chemistry Exam, where the mean is 68%, the standard deviation is 5% and Brian's score is 80% = 2.4.
Final answer:
Brian's z-score is 2.4, calculated using the formula Z = (X - \) / \ by substituting X with Brian's score, \ with the mean score, and \ with the standard deviation. A z-score of 2.4 means Brian scored well above average.
Explanation:
Brian scored an 80% on a Chemistry Exam, where the average was 68%, with a standard deviation of 5%. To find Brian's z-score, use the formula:
Z = (X - \) / \
Where X is Brian's score, \ is the mean score, and \ is the standard deviation. Plug in the values:
Z = (80 - 68) / 5 = 12 / 5
Brian's z-score is 2.4, which means his score is 2.4 standard deviations above the mean. A z-score tells how many standard deviations an element is from the mean. If it's positive, the score is above average; if negative, below average.

The answer is D, if that is what you meant.
The 1/4 must be positive since the 1/2 is positive in the equation and the second numbers are all positive in the choices.
Also, 1/4 of 2 is 1/2, so D has to be the answer.

An item has a listed price of $35.If the sale tax rate is 5%, how much is the sales tax (in dollars)
The tax is 5% of 35 so we have to find out what 5% of 35 is. To do so, divide 5 by 100, then multiply the quotient by 35.
5% ⇒ 0.05
35 × 0.05 = 1.75

t = 7m
Let m = 6
t = 7*6 = 42
Let m = 8
t = 7*8
t = 56
Answer:
For this, all you have to do is multiply each number on the left by 7.
T = 7m
M= 6 x 7
T = 42
M = 8 x 7
T = 56.
Which is the correct first step in finding the height of a cylinder with a volume of 178 cubic inches and a radius of 8 inches?
Va sern
8= (178)
WV = arh
V = x+(8)2 + 178
V= seh
V= 548)? (178)
V = xin
178 = $(8)
The correct first step is to apply the formula for the volume of a cylinder, [tex]\(V = \pi r^2 h\)[/tex], and then rearrange it to solve for the height by dividing the volume by [tex]\(\pi r^2\).[/tex] (Last option)
The correct first step in finding the height of a cylinder with a given volume and radius is to use the formula for the volume of a cylinder:[tex]\(V = \pi r^2 h\)[/tex], where V is the volume, r is the radius, and h is the height.
To solve for h, we must rearrange the equation to isolate h.
Therefore, the correct first step would be to divide both sides of the equation by [tex]\(\pi r^2\)[/tex] to solve for h:
[tex]\[ h = \frac{V}{\pi r^2} \][/tex]
In the case given where the volume (V) is 178 cubic inches and the radius (r) is 8 inches, it would look like:
[tex]\[ h = \frac{178}{\pi \times 8^2} \][/tex]
After performing the calculations, this will give us the height (h) of the cylinder.
So the correct first step would be to apply the formula for the volume of a cylinder, [tex]\(V = \pi r^2 h\)[/tex], and then rearrange it to solve for the height by dividing the volume by [tex]\(\pi r^2\).[/tex]

What is histogram?A histogram is a visual representation of statistical data that makes use of rectangles to illustrate the frequency of data items in a series of equal-sized numerical intervals. The independent variable is represented along the horizontal axis and the dependent variable is plotted along the vertical axis in the most popular type of histogram.
We need to spot less than 20 plant species.
From the given histogram,
Between the interval 0-9 there is 1 spice plant.
Between the interval 10-19 there is 2 spice plant.
So, total = 1+2=3
