The monthly membership costs include a $10 basic fee plus $2 for each DVD she rents. Which equation describes v, the number of DVDs Ingrid can rent, based on T, the amount she spends for membership costs per month?
A. v= t/2 - 5
B. v= t/2 - 10
C. T= v/2 - 10
D. T= v/2 - 5
Answer:
A) v = T/2 - 5
Step-by-step explanation:
T = 10+2v
2v = T-10
v = (T-10)/2 = T/2-5
The equation that describes no. of DVDs that Ingrid can rent is A. v = (T/2) - 5.
What is an equation?An equation states that terms on both sides of the equality sign are equal.
The monthly membership costs 10 dollars, and The rent for each DVD costs 2 dollars.
No. of DVDs that can be rented is denoted by v based on T.
The equation that describes the total cost of renting DVDs is,
T = 2v + 10.
∴ The equation that describes no. of DVDs that can be rented is
2v = T - 10.
v = (T/2) - 5.

At your first job you make $1200 a month of that you save $200 a month. Your goal is to save 20% did you reach your goal?
Answer:
No, you didn't
Step-by-step explanation:
20% of $1200 is:
0.2*$1200 = $240Since you saved $200 and its less than $240 you didn't reach your goal
Hi there!
No:
200 is only 6 parts of 1200 together which means that it can’t be 20% of 1200.
If it was 20% of 1200, it would then be 240 since 240·5=1200...
What this means:
No, did not reach the goal since 20% of 1,200 is 240 and 200 is only 16.67% of $1,200.

50,60,72 find the 8th term airthmetic and geometric sequence
Answer:
8th term is 179.15904
Step-by-step explanation:
The sequence is geometric with a common ration = 6/5
r = 60/50 = 72/60 = 6/5
Use the formula
[tex]a_{n} = ar^{n - 1}[/tex]
In your case a = 50, r = 6/5 and n = 8
[tex]a_{8} = 50(6/5)^{8 - 1} \\ = 50(6/5)^{7} \\ = 50(279936/78125)\\ = 179.15904[/tex]

Step-by-step explanation:
The cost to produce the master disc of a DVD is $2000, while additional discs costs $4 each. Determine a profit function P that results if the DVDs are sold for $15. Find the profit from selling 2800 DVDs.
Find p(x)
Step-by-step explanation:
p(x) = 15x-(2000+4x)
profit is going to be the difference between how much money you get from sales less the cost to make the items
the money you make in this case is $15 times the number of cds you sell, we will call the number of cds x
so 15x is the money from sales
the costs you have are 2000 to create the master and then $4 for every cd you create, so your costs will be 2000+4x
so profit is sales minus costs, therefore we get
p(x) = 15x - (2000+4x)
now to find specifically the profit when we create and sell 2800 cds, x = 2800, so we substitute that value in for x
p(2800) = 15(2800) - (2000+4(2800))
= 42000 - (2000+11200)
= 42000 - 13200
= 28800
The profit of selling 2800 additional DVDs is 28800 dollars.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, The profit function is P, and let no. of DVDs sold is x and the profit on each additional disc is,
= $(15 - 4).
= $11.
∴ The profit function p is,
P = 11x - 2000.
So, the profit by selling 2800 additional discs is,
P = 11(2800) - 2000.
P = 30800 - 2000.
P = 28800 dollars.

Solve the linear system of equations using addition. Graph the equations to verify your solution. -4x = y + 3 y=-4x - 3
-4x = y + 3
y = -4x - 3 => 4x = -y - 3
-4x = y + 3
4x = -y - 3
----------------
0 = 0 (always true)
All Real Numbers
Answer:
x = x, y = -3 - 4x
Step-by-step explanation:
Subtract y from both sides of the equation.
-4x - y = 3
y = -4x - 3
Add 4x to both sides of the equation.
-4x - y = 3
y + 4x = -3
-4x - y = 3
Reorder the polynomial.
Add the two equations together to eliminate y from the system.
-4x - y = 3
+ 4x + y = -3
0 = 0
Since 0 = 0, the equations intersect at an infinite number of points.
Infinite number of solutions.
Solve one of the equations for y.
y = -3 - 4x
The solution is the set of ordered pairs that make y = -3 - 4x true.
Point form: (x, -3 -4x)
Equation Form: x = x, y = -3 - 4x

Sara’s ice cream looks pretty normal. It is shaped like a cone topped with a half-sphere. The cone has a height of 9 in and a radius of 4 in.
What is the approximate volume of the whole shape? Round your answer to the nearest tenth. Use 3.14 to approximate pi. (Show your work.)
Answer: 284.7
Step-by-step explanation:
radius of cone and hemisphere are the same
volume of half sphere=(1/2)*(4/3)*[tex]\pi r^{3}[/tex]
=(1/2)*(4/3)*3.14*[tex]4^{3}[/tex] (4*4*4=64)
=133.97333
=133.97
volume of cone= (1/3)[tex]\pi r^{2}[/tex]h
=(1/3)*3.14*[tex]4^{2}[/tex]*9 (4*4=16)
=150.72
total volume=133.97+150.72
=284.69

Each quadrilateral below is a parallelogram. Find the missing measures
Answer:
GH = 13
FG = 20
<F = 78
<G = 102
<H = 78
Step-by-step explanation:
Since there are 5 measures that are missing, we will do each one in a different part.
1. The side length of GH is 13. Since this is a parallelogram, the opposite side of your original side is congruent, meaning that its the same. So, knowing that the opposite of FI is GH, we can say that GH is 13 units long.
2. We can use the same logic for number 2, when finding FG. Since HI is 20. we can say that since the corresponding side is also congruent to our original length, they are equivalent. Basically meaning they are the same
3. a. For finding F, we will need to use a different method. Since a parallelogram is somewhat like a transversal we can use that to our advantage. (If you don't know what a transversal it, look at part B instead) Since we know that angle I is 102, and both line FG and HI are parallel, the angles are basically adjacent, when switched. So we should see that it would have to be 78. Meaning that F is 78.
3. b. If you don't understand what a transversal is, we can still figure it out. Knowing that the figure is a closed shape, along with knowing that its a parallelogram, we can say that if we were to sum the angles F and I, we would get 180. 180-102=78, so F is 78.
4. Since we can use a transversal or just pure logic to say that angle G and I are equivalent, meaning that G is 102.
5. This one is exceptionally simple, just for the fact that we have answered the previous questions. We have H left, which is not only equivalent to F, but using 3. b. we can say that its would only make sense that H is 78 as well, to sum up that half to 180.

What is the volume of a cone with a diameter of 8 in and a height of 5 in?
Answer:
V=80π/3 or V=83.78
Step-by-step explanation:
The volume is
V=πr^2h/3
r=4 (because the radius is half the diameter)
h=5
V=π16*5/3
V=80π/3
Answer:
83.73
Step-by-step explanation:
volume = (1/3) · π · r2 · h
volume = (1/3) x 3.14 x 4^2 x 5
volume = (1/3) x 3.14 x 16 x 5
3.14 x 16 x 5 = 251.2
1/3 x 251.2

determine the degree measure of an arc whose central angle measures 4pi/15 radians
Answer:
[tex]\boxed{\textsf{ The degree measure is \textbf{ 48}$^{\textbf{o}}$.}}[/tex]
