Explanation 1:
Her guinea pig is
25 cm long.
25 cm = 250 mm
Her fish is 40 mm long, so her guinea pig is longer than her fish by
25 cm − 40 mm = 250 mm − 40 mm = 210 mm= 21 cm
Explanation 2:
First, lets convert the length of Naomi's guinea pig from cm to mm.
1 cm=10 mm
We can multiply each side of the equation by 25 to obtain the length of the guinea pig in mm.
25 × 1 cm = 25 × 10 mm
25 cm = 250 mm
Because we have a length of the guinea pig and the fish in a common metric we can subtract the two values: 250 mm − 40 mm = 210 mm The guinea pig is 210 millimeters longer than the fish. Or, if we want to convert this to centimeters we can divide by 10: 210 millimeters 10 = 21 centimeters
Hope this helps have a good day/night!

To find the y-value that matches with the x-value, we will need to plug in the x-value and simplify the expression.
f(-2) = sqrt(-2 + 2) - 6
f(-2) = sqrt(0) - 6
f(-2) = -6
f(-1) = sqrt( -1 + 2) - 6
f(-1) = sqrt(1) - 6
f(-1) = 1 - 6
f(-1) = -5
f(2) = sqrt(2 + 2) - 6
f(2) = sqrt(4) - 6
f(2) = 2 - 6
f(2) = -4
f(7) = sqrt(7 + 2) - 6
f(7) = sqrt(9) - 6
f(7) = 3 - 6
f(7) = -3

how is the radius and area of a circle proportional
Answer:
The factor '2 pi' is simply the constant of proportionality between C and R. So the area of a circle is proportional to R2 and pi is the constant of proportionality between the area and the radius of a circle.
Answer: The relationship between the area of a circle and the radius of the circle can be stated as follows: The area of a circle is proportional to the square of the radius. Written in symbolic notation: A = R 2 RELATIONSHIP 5.1 Area = x (radius) squared OR A = R 2

Step-by-step explanation:
Use the Theorem of Pappus to find the exact volume of a general cone created by rotating a triangle with vertices ( 0 , 0 ) , ( 1 , 0 ) , and ( 0 , 8 ) around the y -axis.
The exact volume of a general Cone is [tex]\frac{8\pi}{3}[/tex]
To solve this problem, we will make use of the second theorem of Pappus. This theorem is concerned with finding the volume produced when a plane shape is rotated around an axis ( the volume of the solid of revolution ).
The theorem states:
The volume of a solid of revolution obtained by rotating a lamina F (the triangle) about a non-intersecting axis (the y-axis) lying in the same plane is equal to the product of the area A of the lamina F and the distance d traveled by the centroid of F.
That is
[tex]V=A\times d[/tex]
When the centroid travels, it forms a circumference d given by,
[tex]d=2\pi r[/tex]
Therefore
[tex]V=A\times 2\pi r[/tex]
From the diagram below,
The vertices (or, corners) of the triangle are A(0, 0), B(1, 0), and C(0,8).
G is the centroid of the triangle. The centroid of the triangle is the geometric center of the triangle. The centroid would be the balance point if a pin were to be used to balance the triangle.
r is the distance from the centroid to the axis of rotation ( the y-axis in this case). It is like saying the radius of rotation.
The things we need to find are A (the Area) and r.
Calculate A:
[tex]A=\frac{1}{2} \left| \Delta \right|[/tex]
[tex]\Delta = \left|\begin{array}{cc} x_{B}-x_{A} & y_{B}-y_{A} \\ x_{C}-x_{A} &y_{C}-y_{A}\end{array}\right|= \left|\begin{array}{cc} 1-0 & 0-0 \\ 0-0 & 8-0\end{array}\right|= \left|\begin{array}{cc} 1 & 0 \\ 0 & 8\end{array}\right|[/tex]
[tex]\Delta =8\times 1 -0\times 0=8[/tex]
[tex]A=\frac{1}{2} \left|8\right|=\frac{1}{2}\times 8=4[/tex]
Calculate r:
[tex]r=\overline{x}=\frac{x_A+x_B+x_C}{3}=\frac{0+1+0}{3}=\frac{1}{3}[/tex]
Finally, Calculate the volume, V:
[tex]V=A\times 2\pi r=4 \times2\pi\times\frac{1}{3}=\frac{8\pi}{3}[/tex]

Step-by-step explanation:

Write the equation of the parabola in vertex form.
vertex (3,3), point (2, - 1)
Step-by-step explanation:
The vertex form of a parabola is given by
[tex]y = a(x - h)^2 + k[/tex]
where (h, k) are the coordinates of the vertex of the parabola. So we can write our parabola as
[tex]y = a(x - 3)^2 + 3[/tex]
We know that our curve goes through the point (2, -1) so we can solve for the constant a as follows:
[tex]-1 = a(2 - 3)^2 + 3 \Rightarrow -1 = a + 3[/tex]
or
[tex]a = -4[/tex]
Therefore, the vertex form of the equation for the parabola is
[tex]y = -4(x - 3)^2 + 3[/tex]

Seven more than twice a number is greater than negative nineteen. Find all numbers that make this statement true.
The answer is I (Type an inequality using x as the variable.)
Answer:
Hey there,
Let the unknown number be x
Here they say that ,
Seven more than twice a number,
2x + 7
Is greater than,
2x + 7 >
Negative 19,
2x + 7 > -19
Now solve for x
[tex]2x + 7 > - 19 \\ 2x > - 19 - 7 \\ 2x > - 26 \\ \frac{2x}{2} > \frac{ - 26}{2} \\ x > - 13[/tex]
So,
All the numbers which are greater than (-13) makes this statement true.
Examples
[tex]x = { - 12, - 11, - 10, - 9...} \\ [/tex]
Hope this helps you.
Let me know if you have any other questions :-):-)
All numbers that makes, the statement "Seven more than twice a number is greater than negative nineteen" True, are the numbers greater than -13.
Let us denote the unknown number as "x",
The given statement can be translated into an inequality as follows:
7 + 2x > -19,
Now, to solve for "x," we separate the variable by subtracting 7 from both sides of the inequality,
We get,
2x > -26
Divide both sides by 2:
We have,
x > -13
Therefore, any number greater than -13 would make the statement "Seven more than twice a number is greater than negative nineteen" true.
In interval notation, this would be written as (-13, ∞), indicating all real numbers greater than -13.
