The volume of a water walking ball is $\frac{4}{3}\pi$
cubic meters. Find the diameter of
the water walking ball.
A photo shows a small boy inside a water walking ball in a pool.
The diameter is
meters.
If the radius of the ball is 1 meter. Then the diameter of the ball will be 2 meters.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The volume of a water walking ball (in cubic meters) is given below.
[tex]\rightarrow\dfrac{4}{3}\pi[/tex]
Then the diameter of the sphere will be
We know the volume of the sphere is given as
[tex]V = \dfrac{4}{3}\pi r^3[/tex]
where r is the radius of the ball.
Then the radius of the ball will be
[tex]\rm \dfrac{4}{3}\pi = \dfrac{4}{3}\pi r^3\\\\r^3 \ = 1\\\\r \ \ = 1\ m[/tex]
Then the diameter of the ball will be
d = 2r
d = 2 × 1
d = 2 m

Write an explicit formula for an,the Nth term of the sequence 4,12,36
Answer:
[tex]3^{n}+3^{n-1}[/tex]
Step-by-step explanation:
Since the sequence is geometric (it multiplies the previous number each time). The nth term sequence would be [tex]x^n + yn[/tex]
Because the sequence multiplies by 3 each time, The base number in that equation would be [tex]3^n +yn[/tex].
So [tex]3^n[/tex] of the equation would be:
[tex]3, 9, 27[/tex].
Compare the 2 equations:
4, 12, 36
3, 9 ,27
The difference between the 2 equations is: 1, 3, 9 which itself is a geometric sequence so the nth term of this new equation is: [tex]3^{n-1}[/tex].
Combine these 2 equations together and you get:
[tex]3^{n}+3^{n-1}[/tex].

The difference between a number and three fourths of itself is 15. Find the number.
Answer:
60
Step-by-step explanation:
lets say the number is X so:
X-3/4X=15
then multiple both sides by 4 then you will get
4X-3X=60
SO:X=60
Answer:
60Step-by-step explanation:
let x be the number that we are trying to figure out.
the statement “The difference between a number and three fourths of itself is 15” means x + (3/4)x = 15
then
(1/4)x = 15
Then
x = 4 × 15
Then
x = 60

x(adjucent ) = 3.8
Step-by-step explanation:
okay so you are been giving me a left angle triangle so what you are supposed to do is that the longest part which is indicated 7.4 is called the hypothesis whiles the other side indicated 3.6 is called the opposite and the down part is the adjacent. so to find the adjacent your formula is opposite + adjacent = hypothesis .
so therefore we can see that
3.6 + x = 7.4
x = 7.4 - 3.6
x = 3.8

Step-by-step explanation:
X= -4x-4=-4(x+2)
X=-4x-4=-4x-8
X=-4x+4x=-8+4
X=-4
Answer:
so there is no x but it looks like it is undefined
Step-by-step explanation:
-4x - 4 = -4(x+2) 1. multiply -4 with x and 2
-4x - 4 = -4x - 8 2. + 4 on both sides
-4x = -4x - 4 3. +4x on both sides

[tex]3 \sqrt{17}[/tex]
Step-by-step explanation:
The given triangle is a right triangle. Therefore, we can use Pythagoras Theorem to find the measure of the third side.
Pythagoras Theorem
[tex]a^2+b^2=c^2[/tex]
where:
a and b are the legs of the right trianglec is the hypotenuse (longest side) of the right triangleFrom inspection of the given triangle:
a = 4c = 13To calculate the measure of the third side "b", substitute the given values into the formula and solve for b:
[tex]\begin{aligned}a^2+b^2 & = c^2\\\implies 4^2+b^2 & = 13^2\\16+b^2 & = 169\\16+b^2-16 & = 169-16 \\b^2 & = 153\\\sqrt{b^2} & =\sqrt{153}\\b & = \sqrt{9 \cdot 17}\\b & = \sqrt{9}\sqrt{17}\\b & = 3\sqrt{17}\end{aligned}[/tex]
Therefore, the measure of the third side of the given right triangle in simplest radical form is [tex]3 \sqrt{17}[/tex].
