A sphere has a surface area of 803.84 cm^2. What is the volume?
Answer:
V≈2143.03cm³
Step-by-step explanation:
The volume of the sphere is 2143.57 cm³.
What is the surface area of the sphere?A = 4 × π × r², where 'r' is the radius of the sphere.
What is the volume of the sphere?V = (4/3) × π × r³
For given example,
a surface area of the sphere is 803.84 cm^2.
⇒ A = 803.84 cm²
Using the formula of the surface area of the sphere,
⇒ 4πr² = 803.84
⇒ r² = 64
⇒ r = 8 cm
Using the formula of the volume of the sphere,
⇒ V = (4/3) × π × r³
⇒ V = (4/3) × 3.14 × 8³
⇒ V = 2143.57 cm³
Therefore, the volume of the sphere is 2143.57 cm³.

The equation 3x – 2y = 18 is in slope intercept
form.
If the y variable was isolated, it would be in
1
form.
(Use all lowercase letters when writing the answers)
Given:
The equation is:
[tex]3x-2y=18[/tex]
To find:
The slope intercept form of the given equation.
Solution:
Slope intercept form of a line is:
[tex]y=mx+b[/tex]
Where, m is slope and b is y-intercept.
We have,
[tex]3x-2y=18[/tex]
It is not in the slope intercept form.
We need to isolate variable y to get the slope intercept form.
The given equation can be rewritten as:
[tex]-2y=-3x+18[/tex]
[tex]y=\dfrac{-3x+18}{-2}[/tex]
[tex]y=\dfrac{-3x}{-2}+\dfrac{18}{-2}[/tex]
[tex]y=\dfrac{3}{2}x-9[/tex]
Therefore, the slope intercept form of the given equation is [tex]y=\dfrac{3}{2}x-9[/tex].

Check if (1,6) is the solution to the system shown below.
Answer:
NO it is not
Step-by-step explanation:
To check that, we will need to substitute the value of each of the coordinates in each of the equations
10x-y = -6
substitute 1 for x and 6 for y
we have this as;
10(1)-6 = 4
Outrightly, we can see that the given point is not a solution to the given system of equations
however, let us confirm for the second
We have this as;
-10(1) + 5(6)
= -10 + 30 = 20
so we can confirm that it does not work for any of the two and our answer is NO
Skylar has a collection of 60 comic books. She gave away some of her comic books to her friend. After she gave them away, she had 48 still. What percent of her comic books did Skylar give away?
Answer:
the percent of her comic books did Skylar give away is 20%
Step-by-step explanation:
Given that
Skylar has a collection of 60 comic books
She gave away some of her books
And she left by 48 books
we need to find out the percent of the skylar give away books
= (60 - 48) ÷ 60
= 12 books ÷ 60 books
= 20%
Hence, the percent of her comic books did Skylar give away is 20%

The type of Sequence from [tex]a_1[/tex] = 2 and [tex]a_n[/tex] = [tex]a_{n-1}[/tex] + 4 is Arithmetic and recursive.
What is Arithmetic Sequence ?In algebra, an arithmetic sequence is a set of numbers whose every two consecutive terms have the same difference.
An arithmetic sequence is one in which each phrase grows by adding or removing a certain constant, k. In a geometric sequence, each term rises by dividing by or multiplying by a certain constant k.
For example in the arithmetic sequence 3, 9, 15, 21, 27, the common difference is 6.
Given:
[tex]a_1[/tex] = 2
[tex]a_n[/tex] = [tex]a_{n-1}[/tex] + 4
We know that the Arithmetic Sequence is of two forms
Explicit Form : [tex]a_n[/tex] = a+ (n-1)d
and, Recursive form: [tex]a_n[/tex] = [tex]a_{n+1}[/tex] + d
Now, we have [tex]a_n[/tex] = [tex]a_{n-1}[/tex] + 4 which is in the form of Recursive.

Two birds sit at the top of two different trees. The distance between the first bird and a birdwatcher on the ground is 32 feet. The distance between the birdwatcher and the second bird is 45 feet.
A triangle is created from point Bird Watcher, point First Bird, and point Second Bird. Angle First Bird is a right angle, and angle Second Bird measures x degrees.
What is the angle measure, or angle of depression, between this bird and the birdwatcher? Round your answer to the nearest tenth.
35.4°
44.7°
45.3°
54.6°
Answer:
The correct angle is 45.3°
Step-by-step explanation:
Since the opposite side of the angle is 32 feet, and the hypotenuse of the right triangle is 45 feet, you would know that the sine of x° is equivalent to [tex]\frac{32}{45}[/tex]. To find the value of x, take the arcsin of both sides and you'll get that [tex]x = arcsin(\frac{32}{45})[/tex] ⇒ [tex]x[/tex] ≈ 45.3°.
MATHEMATICAL CONNECTIONS Find the dimensions of the polygon with the given area.
Area = 44 ft2
Answer:
Length = 11
Width = 4
Step-by-step explanation:
The value of dimension are;
Length of polygon is 11 ft.
Width of polygon is 4 ft.
Here,
Area of polygon = 44 ft^2
Length of polygon = ( x - 5 ) ft
Width of polygon = ( x - 12 ) ft
We have to find the dimension of polygon.
What is the polygon?
A two-dimensional geometric figure that has a finite number of sides, is called polygon.
Now,
Area of polygon = 44 ft^2
Length of polygon = ( x - 5 ) ft
Width of polygon = ( x - 12 ) ft
Since, Area of polygon = length x width
Hence,
[tex]44 = ( x - 5 ) ( x - 12 )\\\\44 = x^{2} -5x-12x+60\\\\x^{2} - 17x + 16 = 0[/tex]
After factorizing we get;
[tex]x^{2} - 16x - 1x + 16 = 0\\\\x ( x-16) -1 ( x - 16)= 0\\\\(x-1)(x-16)=0[/tex]
[tex]x = 1, x = 16[/tex]
Since, x = 1 is not possible because its gives the values of dimension in negative.
So, x = 16
Now,
Length of polygon = ( x - 5 ) ft = 16 - 5 = 11 ft
Width of polygon = ( x - 12 ) ft = 16 - 12 = 4 ft
Therefore, Length of polygon is 11 ft.
Width of polygon is 4 ft.
