Which image shows a plane slicing a double-napped cone to produce a hyperbola?
Answer is D
The second image in the diagram is a hyperbola. As can be seen, the plane cutting the cone can be at any angle but never equal to the slant angle of the cone. This has a very important implication. The plane cuts both cones of the double-napped cone. The third double-napped cone of Figure 3 shows two hyperbolas.
The plane sliced a third double-napped cone to produce a hyperbola
The second image in the diagram is a hyperbola.
As can be seen, the plane cutting the cone can be at any angle but never equal to the slant angle of the cone.
What is the slant angle?The slant angle of a pick is defined as the angle between the axis of the pick and the normal direction of the rock surface being cut by the pick.
This has a very important implication.
The plane cuts both cones of the double-napped cone.

Answer: Angle 1 is 117.6⁰, the alternate angle to 1 is also 117.6⁰
X is 24.8
The Angle 2X + 12.8 = 62.4⁰, the alternate angle to it is also 62.4⁰
Step-by-step explanation: Angle (2X + 12.8 )forms 1180⁰ with Angle 1
180⁰- 117.6⁰ = 2X + 12.8
62.4⁰ = 2X + 12.8

Answer:
1/12 + 3/12 = 4/12 (or 1/3)
Step-by-step explanation:
we want to express
1/12 + 1/4 as 1/12 + something / 12
1/12 + 1/4 = 1/12 + something/12
we already have the 1/12 part, so we're left with
1/4 = something / 12
first, we can calculate (denominator we want) / (denominator we have) = 12/4 = 3
then, we want to multiply our current value (1/4) by our result of the multiplication divided by itself.
3/3 = 1
1/4 = 1/4 * 1 = 1/4 * 3/3 = 3/12
thus, our second value is 3/12
we then have 1/12 + 3/12
if we have the same denominators, we can simply add the numerators up
1/12 + 3/12 = (1+3)/12 = 4/12

Answer:
Approximately normal
Mode: 4
Range:9
Step-by-step explanation:
The data is pretty evenly spread, the data isn’t pushed to the left or right giving the answer of approximately normal.
Mode: The number that occurs the most is the mode. This means that 4 would be the answer because it has the most dots.
Range: To find the range subtract the smallest number from the biggest number. In this case you would get 9-0 (this is because no data is recorded for 10) which equals 9.

Electric utility poles in the form of right cylinders are made out of wood that costs $25.46 per cubic foot. Calculate the cost of a utility pole with a diameter of 1.5 ft and a height of 30 ft. Round your answer to the nearest cent.
Answer:
$1349.75
Step-by-step explanation:
Use the equation for volume of a cylinder - pi * radius^2 * height
Halve the diameter to find the radius - 1.5 / 2 = 0.75 ft
Find the volume of the cylinder - pi * 0.75^2 * 30 = 53.0143760293 cubic feet or ft^3
Multiply volume by cost per cubic foot - 53.014... * 25.46 = 1349.746013706

Answer:
$5.63
Step-by-step explanation:
We can form a ratio to solve this problem

18/12 = 1.5 times rate
1.5(12):1.5(3.75)
18:5.625, rounded to 5.63

Question 3
What do the range and interquartile range tell you about Arnold and Jackson's training times?
Select each correct answer.
Arnold's training times are more consistent than Jackson's.
Arnold and Jackson's training times have the same spread.
Jackson's training times are just as consistent as Arnold's.
Jackson's training times have the most spread.
Range for Arnold: 18; IQR: 12
Range for Jackson: 20; IQR: 13
Jackson's had the greatest spread.
Arnold's middle 50% had the least spread
What is the Range and Interquartile Range of a Data Set?Range = Maximum value - minimum value
Interquartile range (IQR) = Q3 - Q1
Range and IQR are both measures of variability. The larger the value, the more spread the data values in a data set are.
Range for Arnold's training times = 102 - 84 = 18
Range for Jackson's training times = 103 - 83 = 20
Therefore, Jackson's training times had the greatest spread.
Interquartile range for Arnold's training times = Q3 - Q1 = 99 - 87 = 12
Interquartile range for Jackson's training times = Q3 - Q1 = 100 - 87 = 13
Thus, Arnold's middle 50% of his training times had the least spread.
The range and interquartile range tells us that, Arnold's training times are more consistent than Jackson's.

Melissa has a student dictionary on her desk. Her dictionary contains 99 pages. In this dictionary, more words start with the letter "S" than any other letter, occupying 11 full pages.
If she opens up the dictionary at random, what is the probability that the page contains words starting with "S"?
Answer:
I believe it is 1/9 or 11.1%
Step-by-step explanation:
11/99 /(divided by) 11 = 1/9
1/9 converted to a decimal is 0.1 (it's repeating- I am not sure how to do that on brainly w/ the fancy - over it, so it's 0.111111111...)

7. The perimeter of a right triangle is 60 cm and its hypotenuse is 25 cm. Find the area of the triangle.
Answer:
150 cm²
Step-by-step explanation:
Given
Perimeter = 60 cmHypotenuse = 25 cmSolving
We need to find the lengths of the altitudesSince 25 cm is already covered there is (60 - 25) = 35 cm remainingThe lengths can be taken as x and 35 - xNow, since it's a right triangle, we can solve for x using the Pythagorean TheoremApplying the theorem
x² + (35 - x)² = 25²x² + 1225 - 70x + x² = 6252x² - 70x + 600 = 0x² - 35x + 300 = 0x = 35 ± √1225 - 4(1)(300) / 2x = 35 ± √25 / 2x = 35 ± 5 / 2x = 40/2 = 20 or x = 30/2 = 15Upon solving the lengths of the altitudes are 15 and 20Area of the triangle

Remark
Normally you would have to make sure that the bottoms of each fraction to be added would be the same. In this question, they are, so nothing further to getting the bottoms the same has to be done,
Solution
answer = 7 / 16 + 3 / 16
answer = (7 + 3) / 16
answer = 10/16
Both top and bottom are even numbers so you can divide both top and bottom by at least 2.
10/2 = 5

Solution of equation ( x ) = 7Step-by-step explanation:
In this question we have given with an equation that is 4 ( 5x - 2 ) = 2 ( 9x + 3 ). And we are asked to solve this equation that means we have to find the value of x.
Solution : -
[tex] \quad \longrightarrow \: 4 ( 5x - 2 ) = 2 ( 9x + 3 )[/tex]
Step 1 : Removing parenthesis :
[tex] \quad \longrightarrow \:20x - 8 = 18x + 6[/tex]
Step 2 : Adding 8 from both sides :
[tex] \quad \longrightarrow \:20x - \cancel{ 8 }+ \cancel{8} = 18x + 6 + 8[/tex]
On further calculations we get :
[tex] \quad \longrightarrow \:20x = 18x + 14[/tex]
Step 3 : Subtracting 18 from both sides :
[tex] \quad \longrightarrow \:20x - 18x = \cancel{18x }+ 14 - \cancel{18}[/tex]
On further calculations we get :
[tex] \quad \longrightarrow \:2x = 14[/tex]
Step 4 : Dividing with 2 on both sides :
[tex] \quad \longrightarrow \: \frac{ \cancel{ 2}x}{ \cancel{2}} = \cancel{\frac{14}{2} }[/tex]
On further calculations we get :
