Find the circumference of the circle. Use 3.14 !! (No link)
Answer:
62.8 ft
Step-by-step explanation:
Given,
Diameter = 20 ft ( from the diagram )
pi = 3.14
To find : Circumference ( circle ) = ?
Radius ( r )
= Diameter / 2
= 20 / 2
= 10 ft
Formula : -
Circumference ( circle ) = 2 pi r
Circumference ( circle )
= 2 x 3.14 x 10
= 2 x 31.4
= 62.8 ft

What is the height of the pyramid?
Answer:
4
Step-by-step explanation:
The slant height of the pyramid is marked as 5. If we drew and auxiliary 2D right triangle in the pyramid, this slant height would be the hypotenuse and one of the legs would be the height of the pyramid. The base leg would be equal to half of a side of the pyramid (3). Therefore, we can use the Pythagorean theorem to find the height ([tex]h[/tex]):
[tex]3^2+h^2=5^2,\\h^2=16,\\h=\boxed{4}[/tex]
what is the radius of the circle which has the given equation? (x - 2)2 + (y + 1)2 = 16
Answer:
r = 4units
Step-by-step explanation:
The standard foem of equation of a line is expressed as;
(x-a)² + (y-b)² = r²
r is the radius
Compare with the given equation (x - 2)^2 + (y + 1)^2 = 16
r² = 16
r = √16
r = 4
Hence the radius of the circle is 4

15 pts, Trigonometic ratios. Please solve as it says on the mandate, Thanks!
Answer:
WY = 8
Step-by-step explanation:
We solve for above question using the Trigonometric function of Sine
sin θ = Opposite/Hypotenuse
Opposite = WY = x
Hypotenuse = 9
θ = 63°
Hence,
sin 63° = x/9
Cross Multiply
x = sin 63° × 9
x = 8.0190587177
Approximately x = 8
Therefore, WY = 8
Find x rounded to the nearest while number
Answer:
10.35
Step-by-step explanation:
The given triangle is a right angled ∆ .The data given is ,
Base = x Hypontenuse = 23 Angle = 63° .We can use ratio of cosine here , as ,
=> cos∅ = b/h
=> cos 63° = x/23
=> 0.45 = x/23
=> x = 23 × 0.45
=> x = 10.35
Hence the value of x is 10.35Write an inequality that represents eight less than three times a number is more than 22.

What x and y equal to
Answer:
X = 4, Y = 3.
Explanation:
Since the length of side CK is equal to the length of WM, then you can make the equation 6y-4 = 18. then you just add 4 to each side and divide both sides by six to get 3. Same thing for the other equation. Angle (i think its an angle due to its placement) C is equal to angle M, so you can make the equation 3x + 7 = 19. Subtract seven from both sides then divide by 3 to get 4. Tell me if you have any questions :)
Answer and Step-by-step explanation:
We know the triangles are congruent, so if you were to flip one of the triangles onto the other, the will perfectly match up, allowing us to solve for x and y.
19 = 3x + 7
Subtract 7 from both sides.
12 = 3x
Divide each side by 3.
4 = x
14 = 6y - 4
Add 4 to each side.
18 = 6y
Divide each side by 6.
3 = y
x = 4
y = 3

Elena would like to know the average height of seventh graders in her school district. She measures the heights of everyone in a random sample of 20 students. The mean height of Elena’s sample is 61 inches, and the MAD (mean absolute deviation) is 2 inches.
Select all the true statements.
Who every can answer this I will give brainliest!! Please help!
Complete question is;
Elena would like to know the average height of seventh graders in her school district. She measures the heights of everyone in a random sample of 20 students. The mean height of Elena's sample is 61 inches, and the MAD (mean absolute deviation) is 2 inches.
Select all the true statements. Make your selections bold.
A. The median height of the sample must be between 59 and 63 inches.
B. Another random sample of 20 students is likely to have a mean between 57 and 65 inches.
C. The mean height of these 20 students is likely to be the same as the mean height of all students in the district.
D. The mean height of these 20 students is likely to be the same as the mean height of a second random sample of 20 students.
E. Elena would be more likely to get an accurate estimate of the mean height of the population by sampling 40 people instead of sampling 20 people.
Answer:
Options A, B & E are true.
Step-by-step explanation:
We are told that Elena's mean absolute deviation is 2 inches.
This means that the distance between each data point and the mean is equal to 2. This value gives us a good idea about the variability present in the dataset.
This is calculated from the difference between the mean of the absolute value of the initial mean and each data set.
Now, looking at the options. In option A, since mean height of the 20 students is given as 61, it means the median will be close to that figure too. Thus, between 59 and 63 inches given is appropriate.
In option B, if another random sample is taken, the mean would likely be close to 61 too since the MAD is 2.
Thus range given is okay.
In options C & D, there is no evidence to prove that the new mean would be the same as the district or the second random sample. This, both options are not appropriate.
In option E, if she uses a Sample of 40, she will obviously get a more accurate figure because the more the sample the more accurate the average result that represents the population.
