An equation is formed of two equal expressions. The equation that represents the correct relationship between volume, radius, and height is V=khr².
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given the volume of a cone, V varies jointly with its height, h, and the square of its radius, r. Therefore, the relationship can be written as,
V ∝ h(r²)
Also, k is the constant of proportionality, therefore, the equation now can be written as,
V = k×h×r²
Hence, the equation that represents the correct relationship between volume, radius, and height is V=khr².

Q1Angles forming a linear pair are supplementary and sum to 180°
x + 8x = 180°9x = 180°x = 20°The smaller angle is 20°
Q2A(-2, 10) reflected over x-axis
Rule for such a reflection is:
(x, y) → (x, -y)Point A will map to:
(-2, 10) → (-2, -10)Correct option is D
Q3One point is at the origin and two other points are at the distance m horizontally and vertically from the origin
The last point will have same distance m from the point (m, 0) and (0, m) and this will be point:

If Alex has 60 square inches of wrapping paper, does he have enough paper to wrap the gift? (Assume that the shape of the wrapping paper doesn't matter.)
O yes because the gift has a surface area of 48 square inches
O no because the gift has a surface area of 96 square inches
O yes because the gift has a surface area of 32 square inches
O no because the gift has a surface area of 64 square inches
Answer:
yes because the gift has a surface area of 48 square inches
Step-by-step explanation:
Surface area formula:
A = 2(wl + hl + hw)
2 · (4 · 4 + 1 · 4 + 1 · 4) = 48
y times the square root of x
Answer:
When you multiply a whole number by a square root, you just put the two together, with the whole number in front of the square root. For example, 2 * (square root of 3) = 2(square root of 3). If the square root has a whole number in front of it, multiply the whole numbers together.

Step-by-step explanation:
x is on the left side of the < symbol, so the shaded portion of the line will be on the left side of the boundary dot.
The boundary dot is plotted at the constant, which is 1/2 = 2/4. That plot is shown in selection B.

Additional comment
I like to write inequality solutions using the < or ≤ symbols because the relative positions of numbers and variables match their relative positions on the number line. In this problem, we have x < 1/2, so the shaded portion of the line is on the left of the boundary dot, just as x is on the left of 1/2 in the inequality.

The first side of a triangle is 4 inches longer then twice th second side the third side of a trianhle
Question:
The first side of a triangle is four inches longer than twice the
second side. The third side of the triangle is 5 inches shorter than
the sum of the other two sides. The perimeter is 72 inches. Find
the lengths of the three sides.
Answer:
The sides of the triangle are: 11.5, 27 and 33.5
Step-by-step explanation:
Let the first side be f, the second be s and the third be t.
So, we have:
[tex]f =4 + 2s[/tex]
[tex]t = f + s - 5[/tex]
[tex]Perimeter = 72[/tex]
Required
Determine the length of the three sides
Perimeter is calculated as:
[tex]Perimeter = f + t + s[/tex]
Substitute values for f and t
[tex]Perimeter = 4+2s + f+s-5 + s[/tex]
[tex]Perimeter = f+2s +s+s-5+4[/tex]
[tex]Perimeter = f+4s-1[/tex]
Substitute values for f and Perimeter
[tex]72 = 4+2s+4s-1[/tex]
[tex]72 = 2s+4s-1+4[/tex]
[tex]72 = 6s+3[/tex]
Collect Like Terms
[tex]6s = 72 -3[/tex]
[tex]6s = 69[/tex]
[tex]s= 11.5[/tex]
[tex]f =4 + 2s[/tex]
[tex]f = 4 + 2 *11.5[/tex]
[tex]f = 27[/tex]
[tex]t = f + s - 5[/tex]
[tex]t=27+11.5 - 5[/tex]
[tex]t=33.5[/tex]
The sides of the triangle are: 11.5, 27 and 33.5

9514 1404 393
Answer:
(d) 112°
Step-by-step explanation:
Opposite angles in an inscribed quadrilateral are supplementary.
∠P = 180° -∠R = 180° -68°
∠P = 112°
Answer:
112 degrees.
Step-by-step explanation:
This is an isosceles trapezium.
So the required angle = 180 - 68 = 112.

Answer:
aproximately 23.5 I believe
Step-by-step explanation:
ok, so first you square 17, which is 289. then you square 29, which is 841. subtract 289 from that:
841-289=552
now take the square root of 552
aproximately 23.5 I believe
Answer: 23cm
Step-by-step explanation:
a² + b² = c²
x² + 17² = 29²
x² + 289 = 841
x² = 552
√x² = √552
x ≈ 23 cm
