Answer:
Surface Area is the space occupied by a two-dimensional flat surface is called the area.
Total surface area is the area including the base(s) and curved part(s).
Calculating Surface Area:
To find the surface area of a shape, we need to find the measurement (in this case, centimeters) of each face/side and add them together.
Volume:
The amount of space an object/3D shape occupies. (Ex: A circle does not have volume, a sphere, however, does.)
Calculating Volume:
Volume = the length times the width times the height. (Volume = length x width x height)

Find the volume of a cone with a base diameter of 6 in and a height of 6 in. Write the exact volume in terms of , and be sure to include the correct unit in your answer.
The volume of the cone with a base diameter of 6in and height of 6in is 6π in³.
What is the volume of the cone?The volume of a cone is expressed as;
V = (1/3)πr²h
Where r is radius of the base, h is the height of the cone and π is constant pi.
Given the data in the diagram;
Diameter d = 6inRadius r = diameter/2 = d/2 = 6in/2 = 3inHeight h = 6Volume V = ?Plug the given values into the above formula and solve for the volume of the cone.
V = (1/3) × π × r² × h
V = (1/3) × π × ( 3in )² × 6in
V = 18π/3 in³
V = 6π in³
Therefore, the volume of the cone is 6π cubic inches.

C. y=3x+20
D. Standard
E. -4
F. y=3x+12
G. Slope Intercept
H. Point Slope
I. 8
J. y=3x+4
Answer:
Reese will first need to use point slope Formula to plug in- 4 for x1, 8 for y1, and 3 for the m
Reese's final answer will be y = 3x + 20, which is written in slope intercept Form.
Step-by-step explanation:
The answers in terms of the choices and order in which the blanks appear are
H. Point Slope
E. -4
I. 8
B. 3
C. y=3x+20
G. Slope Intercept
The point slope form for a line
y - y1 = m(x - x1)
Pugging in x1 = -4, y1= 8 and m = 3 gives
y -8 = 3(x - (-4))
y - 8 = 3x + 12 Move -8 to right side
y = 3x +12 + 8
y = 3x + 20

substitution y=2y-2 and y=2x-5y=1
Answer:
We can solve for y in the equation y = 2y - 2 by substituting y = 2x - 5.
Starting with y = 2y - 2, we substitute y = 2x - 5:
2x - 5 = 2(2x - 5) - 2
Expanding the right side:
2x - 5 = 4x - 12
Next, we isolate y by subtracting 2x from both sides:
-2x - 5 = 4x - 12
Adding 2x to both sides:
-5 = 6x - 12
Adding 12 to both sides:
7 = 6x
Finally, we divide both sides by 6 to solve for x:
x = 7/6
So, y = 2x - 5 = 2(7/6) - 5 = 7/3 - 5 = -14/3.
Therefore, y = -14/3 is the solution to the system of equations y = 2y - 2 and y = 2x - 5.

Change each algebraic fraction into an equivalent fraction with the denominator of 24a^3b^2.
The algebraic fraction which is an equivalent fraction with the denominator 24a^3b^2 is 15b/24a^3.
To find an equivalent fraction with the denominator 24a^3b^2, we need to find a common denominator for the two fractions 5b and 8a^3. This common denominator is 24a^3b^2.
To find an equivalent fraction for 5b, we can multiply both the numerator and denominator by the same factor to obtain the desired denominator. To do this, we need to find a factor that would give us a denominator of 24a^3b^2 when multiplied with 8a^3.
The factor that would give us a denominator of 24a^3b^2 is 3.
So, the equivalent fraction for 5b with the denominator 24a^3b^2 is (5b * 3)/(8a^3 * 3) = 15b/24a^3.

How to calculate the valuesAn equation simply has to do with the statement that illustrates the variables given. In this case, it is vital to note that two or more components are considered in order to be able to describe the scenario.
1. y = x²
y = 11x - 10
Combine both variables

HELP ! A phone company offers two monthly plans. Plan A costs $30 plus an additional $0.03 for each minute of calls. Plan B has no initial fee but costs $0.18 for each minute of calls. What is the cost when the two plans cost the same for a set number of minutes?
Group of answer choices
$100
$200
$36
$30
The cost when the two plans cost the same for a set number of minutes is $36. Option C is correct.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Plan A costs $30 plus an additional $0.03 for each minute of calls.
This can be expressed in equation as
y=30+0.03x
Plan B has no initial fee but costs $0.18 for each minute of calls.
y=0.17x
Now we have to find the cost when the two plans cost the same for a set number of minutes
30+0.03x=0.18x
30=0.18x-0.03x
30=0.15x
Divide both sides by 0.15
x=200
when the number of minutes of calls is 200, the two plans cost the same.
To find the cost when the two plans cost the same,
we can substitute x = 200 into either expression for Cost_A or Cost_B:
Cost_A = 30 + 0.03(200) = $36
Cost_B = 0.18(200) = $36
Therefore, the cost when the two plans cost the same for a set number of minutes is $36. Option C is correct.

The area and the perimeter of the various given figures above are listed below:
1.) area=70 cm²
perimeter = 29cm
2. area= 80mm²
perimeter = 36mm
3.) area=108m²
perimeter = 42m
4.) area=72cm²
perimeter = 34cm
How to calculate the area and perimeter of the given figures above?For figure 1;
The area of the given figure = length×width.
Where;
Length = 7cm, width = 10
area = 7×10 = 70 cm²
The perimeter = summation of the whole sides.

What is exponential growth?Exponential growth is a process of increasing a quantity over time. It occurs when the rate of change of a quantity with respect to time is proportional to the itself.
Given that, the number of bacteria in a colony doubles every 384 hours and there is currently a population of 2,150 bacteria,
The exponential growth law for this problem is :-
p(t) = 2150(2)ⁿ/₃₈₄
