[tex]Surface\ area = 6728.3125(pi)\\\\Surface\ area = 21137.6171211[/tex]
Step-by-step explanation:
The lateral surface area of an object is the surface area of the subject excluding the base and the top of the 3-dimensional figure. The surface area of the object is the 2-dimensional space of an object, in essence, if one was going to wrap the object, the amount of material they would need to cover the object. To find the lateral surface area of a cylinder, one must find the circumference of the circle at the top of the cylinder, and then multiply it by the height of the cylinder. The circumference of a circle is the distance around it, the perimeter.
The formula one would use is,
[tex]A_s = (pi)(r^2)(h)[/tex]
Were (pi) represent the value (3.1415...), (r) represent the radius of the base, that is the distance from the center point of the circle on the base, to the outside distance of the circle. The radius of a circle is always half of the diameter. (h) represents the height of the figure.
[tex]A_s = (pi)(r^2)(h)\\\\= (pi)((\frac{3.5}{2})^2))(13)\\\\= (pi)(1.75)^2(13)\\\\= (517.5625)(13)(pi)\\\\=(6728.3125)(pi)\\\\= ~21137.6171211[/tex]

James spent $20.16 on comic books. Each comic book cost $0.72. After he read the comic books, James sold each one for $0.20 less than he paid for it. What is the total amount of money that James received from selling his comic books? Enter your answer in the box.
Answers
Answer:
$14.56
Step-by-step explanation:
Steps to answering this question
Determine the total number of comics bought. This can be done by dividing the total amount spent on comics by the unit price of a comic Determine the selling price of the comic multiply the amount of comics bought by the selling pricethe total number of comics bought = total amount spent on comics / per unit price of comics
$20.16 / $0.72 = 28
selling price = 0.72 - $0.20 = $0.52
Total amount received = selling price x total comics bought
$0.52 x 28 = $14.56

Step-by-step explanation:
You would need to find the greatest commen factor in the equation.
it would end up being 4 since it is the biggest number that can divide between 8 and 20.
20/ 4 = 5
8/4 = 2
so you would leave the varibles since you can't take them out and put 4 on the outside of the parantheses.

Determine whether the following equation represents a direct variation If it does, find the constant of variation
2x + 3y = 0
Answers
Given:
The equation is
[tex]2x+3y=0[/tex]
To find:
Whether the equation represents a direct variation. If it does, find the constant of variation.
Solution:
The general equation of direct variation is
[tex]y=kx[/tex] ...(i)
Where, k is the constant of variation.
The equation of direct variation is always true for (0,0).
The given equation is
[tex]2x+3y=0[/tex]
It can be written as
[tex]3y=-2x[/tex]
[tex]y=-\dfrac{2}{3}x[/tex] ...(ii)
For x=0,
[tex]y=-\dfrac{2}{3}(0)[/tex]
[tex]y=0[/tex]
The given equation is true for (0,0). So, it represents a direct variation.
On comparing (i) and (ii), we get
[tex]k=-\dfrac{2}{3}[/tex]
Therefore, the constant of variation is [tex]-\dfrac{2}{3}[/tex].

Answers
Answer:
x = 1 y = -3 (1, -3)
Step-by-step explanation:
Use the Substitution Method
First, you have to turn the equations into slope intercept form (y = mx + b)
First equation
x - y = 4
subtract x from both sides
-y = -x + 4
divide each side by -1
y = x - 4
Second Equation
4x + y = 1
subtract 4x from both sides
y = -4x + 1
Turn the two new equations into one equation like so
-4x + 1 = x - 4
add 4x to both sides
1 = 5x - 4
add 4 to both sides
5 = 5x
divide each side by 5
x = 1
Fill in x in one of the original equations in order to find the value of y
4(1) + y = 1
4 + y = 1
subtract 4 from both sides
y = -3
The solution is (1, -3)hope this helps :)
