The height of right circular cylinder P
is twice the height of right circular
cylinder Q. The radii of the cylinders are
of equal length
What number times the volume of
cylinder Q is equal to the volume of
cylinder P?
A. 2
B. 4
C. 6
D. 8
Answer:
A. 2
Step-by-step explanation:
The computation is shown below:
As we know that
The Volume of a right circular cylinder is
[tex]V = \pi r^h\\\\[/tex]
Here r is the radius
And h is the height
Now it is mentioned that the height of the right circular cylinder P is double to the height of the right circular cylinder Q
Now let us assume h be the height of cylinder p
And, H be the height of cylinder Q
So the equation is
h = 2H ........(1)
Also
The radius of both the cylinders would be the similar length
So
we assume the r be the radius of both cylinders
Now
The Volume of cylinder Q = [tex]V_Q = \pi r^2H[/tex]
And for P it is [tex]V_p = \pi r^2 h[/tex]
Now substitute equation 1
[tex]V_p = \pi r^2(2H)\\\\V_p= 2 \pi r^2hH\\\\V_p = 2(\pi r^2H)\\\\V_p = 2(V_Q)[/tex]
Hence, the correct option is A.

6-8x=7x-10x-24 solve for x
Answer:
x = 6
Step-by-step explanation:
Let's solve your equation step-by-step.
6−8x=7x−10x−24
Step 1: Simplify both sides of the equation.
6−8x=7x−10x−24
6+−8x=7x+−10x+−24
−8x+6=(7x+−10x)+(−24)(Combine Like Terms)
−8x+6=−3x+−24
−8x+6=−3x−24
Step 2: Add 3x to both sides.
−8x+6+3x=−3x−24+3x
−5x+6=−24
Step 3: Subtract 6 from both sides.
−5x+6−6=−24−6
−5x=−30
Step 4: Divide both sides by -5.
−5x/-5 = -30 /-5
x=6

Find the value of x. The diagram is not to scale.
110°
57°
I found one other post on this and the only answer was “show the diagram” please help
Answer:
x = 13
Step-by-step explanation:
110° is the vertically opposite angle of one of the interior angles of the given triangle.
Therefore,
[tex]x \degree + 57 \degree + 110 \degree = 180 \degree \\ \\x \degree + 167 \degree = 180 \degree \\ \\ x \degree = 180 \degree -167 \degree \\ \\ x \degree = 13 \degree \\ \\ x = 13[/tex]
If and are the radi of two concentric circles and (r. > r.). If the chord
of the larger circle AB touches the inter circle. Find the value of AB
Answer:
r1 and r2 are the radii of two concentric circles
To find:
The length of the chord of the larger circle.
Solution:
We have given the two concentric circles which means both the circles have the same centre.
The chord of the larger circle toches the inner circle so the chord of the larger circle will be the tangent of the smaller circle.
And we know that the radius of the circle is perpendicular to the tangent of the circle.
Let 2x be the length of the chord of the circle.
r1 is the radius of the larger circle.
r2 is the radius of the smaller circle.
So by the Pythagoras theorem,
The length of the half of the chord is given by:
r1² = x² + r2²
x² = r1² - r2²
x = √r1² - r2²
So,
The length of the chord will be 2x = 2√r1² - r2² units
Step-by-step explanation:
Observe the graph below. The scale factor used to dilate ABC was...
Answer:
3
Step-by-step explanation:
AB = 1 unit
A'B' = 3 units
The scale of dilation = A'B'/AB
Therefore:
scale of dilation = 3 units / 1 unit = 3
This means that ABC was dilated or enlarged in size by multiplying every of its segment by 3. In essence, A'B'C' is 3 times the size of ABC.

Find the value of x in the
following parallelogram:
2x + 4
6x - 16
x = [?]
Enter
Answer:
2.5Step-by-step explanation:
For parallelogram, the opposite sides are equal. Hence
2x + 4 = 6x - 16
Collect the like terms
2x - 6x = -16 - 4
-8x = -20
x = 20/8
x = 5/2
x = 2.5
Hence the value of x is 2.5

A random sample of 478 children aged 9 to 17 from the United Kingdom and the United States who completed a CensusAtSchool survey in a recent year was selected. Each student's country of origin was recorded along with which superpower they would most likely have?
Answer:
14.02%
Step-by-step explanation:
Missing word "the ability to fly, ability to freeze time, invisibility, superstrength, or telepathy (ability to read minds). The data are summarized in the table below. What percent of children in the sample would most like to have the superpower of invisibility?"
Note: The table is attached below as well
The percentage of children in the sample that would most like to have superpower of invisibility is computed here as:
= n(invisibility) / n(Total)
= (30 + 37) / 478
= 67/478
= 0.1401673640167364
= 14.02%
Therefore, the percent of children in the sample would most like to have the superpower of invisibility is 14.02%

B. y-intercept: (0,-5); vertex point: (2,-9); x-intercepts: (-1,0) and (5,0)
C. y-intercept: (0,5); vertex point: (2,-9); x-intercepts:(-1,0) and (-5,0)
D. y-intercept: (0,-5); vertex point: (-2,-9); x-intercepts: (1,0) and (-5,0)
Answer:
its b
Step-by-step explanation:
The y-intercept: (0,-5); vertex point: (2,-9); x-intercepts: (-1,0) and (5,0) option (B) is correct.
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
We have a function:
[tex]\rm f(x) = x^2 - 4x-5[/tex]
The above function shows a parabola equation.
For y-intercept plug x = 0 in the function.
f(0) = -5
So the y-intercept is (0, -5)
For the vertex:
[tex]\rm f(x) = (x-2)^2-9[/tex] (from perfect square trinomial)
[tex]\rm f(x) = (x-h)^2+k[/tex]
(h, k) is the vertex = (2, -9)
For x-intercept:
f(x) = 0
[tex]\rm x^2 - 4x-5=0[/tex]
After factorizing:
(x+1)(x-5) = 0
So the x-intercept will be:
(-1, 0) and (5, 0)
Thus, the y-intercept: (0,-5); vertex point: (2,-9); x-intercepts: (-1,0) and (5,0) option (B) is correct.
