six episodes of a tv series last total of five hours, How many minutes on average does an episode last
Step-by-step explanation:
[tex]5 \: hours \: = 5 \times 60 = 300 \: min \\ minutes \: per \: episode = \frac{300}{6} \\ = 50 \\ [/tex]
Hence, each episode lasted for 50 minutes on an average.
On average, each episode of the TV series lasts 50 minutes, calculated by converting the total viewing time of five hours to 300 minutes and dividing that by the number of episodes, which is six.
To calculate the average duration of an episode, we need to convert the total time of all episodes from hours to minutes and then divide by the number of episodes.
There are 60 minutes in one hour, so five hours equates to 300 minutes (5 hours × 60 minutes/hour = 300 minutes). With six episodes in total, we divide the total minutes by the number of episodes to find the average length of one episode.
300 minutes / 6 episodes = 50 minutes per episode.
Therefore, on average, each episode of the TV series lasts 50 minutes.

Answer: x = -14/5
Step-by-step explanation: We shall begin by expanding the brackets for both sides of the equation
-2/3 (x + 2) = 1/6 (x + 6)
(-2x/3) -4/3 = (x/6) + 1
By collecting like terms we now have
(-2x/3) - (x/6) = 1 + 4/3
(-4x - x)/6 = 7/3
-5x/6 = 7/3
By cross multiplication we now have
-5x (3) = 7 (6)
-15x = 42
x = -(42/15) {simplify further by dividing the RHS by 3}
x = -14/5
Therefore x equals, minus fourteen over five (-14/5)

Answer: I would say imaginary numbers...
Step-by-step explanation:
It follows the format of imaginary numbers: bi, where i = [tex]\sqrt{-1}[/tex] and b = -91.
Final answer:
The number -91i is an imaginary number, which is a subset of complex numbers with a real part of 0 and an imaginary part of -91.
Explanation:
The number -91i is a complex number.
Complex numbers consist of two parts: a real part and an imaginary part. In this case, the real part is 0 and the imaginary part is -91.
The 'i' represents the imaginary unit, which is defined as √(-1).
Therefore, -91i is an imaginary number because it exists only with the imaginary unit 'i', and does not have a real part.

Angle m and angle n are supplementary angles. If the measure of angle M= 5x+18 and the measure of angle N= 3x+2, find the value of x, and the measure of angle M
Answer:
Step-by-step explanation:
∠ M + ∠N = 180 {supplementary}
5x+18 + 3x + 2 = 180 {Now add the like terms}
8x + 20 = 180
8x = 180 - 20
8x = 160
x = 160/8
x = 20
∠M = 5x + 18 = 5*20 + 18 = 100 + 18 = 118
∠N = 3x + 2 = 3*20 + 2 = 60 + 2 = 62

a mechanical engineer designs a robotic rm to be used in an assembly line. one portion of the arm is 5/12 yard long, and the length of the second portion of the arm is 3/12 yard long.What wouldbe the length, in yards, of the robotic arm if the two portions of the arm were measured end to end?
Answer:
8/12 yard or 2/3 yard
Step-by-step explanation:
The sum of the two lengths is ...
5/12 yd + 3/12 yd = (5+3)/12 yd = 8/12 yd
This fraction can be reduced by removing a factor of 4 from numerator and denominator.
8/12 yd = 2/3 yd
If the arm portions are end-to-end, the total length is 2/3 yard.

A cone with height 8 and radius 2 is sliced halfway along its height by a plane that is parallel to the base of the cone. What is the radius of the circle at the intersection of the plane and the cone?
Answer:
1
Step-by-step explanation:
The cone is sliced by a plane, which produces a smaller cone on top. This cone is similar to the original cone. Therefore:
R / H = r / h
2 / 8 = r / 4
r = 1
The radius of the circle at the intersection of the plane and the cone is 1.
To find the radius of the circle at the intersection of the plane and the cone, we start by understanding the geometry of the cone and the slicing plane.
Given:
- Cone height ( h = 8 )
- Cone radius ( r = 2 )
- The plane slices the cone halfway along its height, so the distance from the vertex to the plane is [tex]\( \frac{8}{2} = 4 \)[/tex].
Let's denote:
- ( R ): Radius of the circle at the intersection of the plane and the cone.
At height ( h ) from the vertex of the cone, the radius ( R ) of the circle formed by the intersection with the plane is related to the similar triangles formed by the cone and the slice plane.
The ratio of corresponding sides of similar triangles gives us:
[tex]\[ \frac{R}{r} = \frac{h - 4}{h} \][/tex]
Substitute the given values:
[tex]\[ \frac{R}{2} = \frac{8 - 4}{8} = \frac{4}{8} = \frac{1}{2} \][/tex]
Now, solve for ( R ):
[tex]\[ R = 2 \cdot \frac{1}{2} = 1 \][/tex]
Therefore, the radius of the circle at the intersection of the plane and the cone is [tex]\( \boxed{1} \).[/tex]

Write equation for the total cost or a cake, where y represents total cost and x represents the number of additional servings. How much would a cake that serves 20 people cost?
The total cost of a cake that serves 20 people is $35.
Step-by-step explanation:
Total cost = yNumber of additional servings = xThe number of additional servings = 20 - 12 = 8. (x=8)The equation can be formed as:
Total cost = basic cost + (No. of additional serving [tex]\times[/tex] cost per additional serving)y = 25 + x1.25Substitute x=8 in the above equationy = 25 + 8(1.25)y =25+10y = 35Therefore, the total cost of a cake that serves 20 people is $35.

Last week Geraldo bought 7 pounds of apples for $5.95. This week apples are the same price, and he buy 4 pounds. How much will he pay?
Answer:
$3.40
Step-by-step explanation:
Final answer:
To determine the cost Geraldo will pay for 4 pounds of apples, we find the cost per pound from his previous purchase and multiply by the desired weight. At $0.85 per pound, Geraldo will pay $3.40 for 4 pounds of apples.
Explanation:
Last week, Geraldo bought 7 pounds of apples for $5.95. To find out how much he will pay for 4 pounds of apples this week at the same price, we first need to calculate the cost per pound of the apples. We do this by dividing the total cost by the total weight in pounds from the previous purchase.
The cost per pound is $5.95 divided by 7 pounds, which equates to approximately $0.85 per pound (rounding to two decimal places).
So, for 4 pounds of apples, Geraldo will pay 4 times $0.85, which results in a total of $3.40.
Therefore, Geraldo will pay $3.40 for 4 pounds of apples.
A carpet installer charges a flat rate of $40, plus $1.50 per square foot for labor. So, the total cost for labor depends on the amount of carpet installed. The relationship between the total cost for labor and the amount of carpet installed is . The domain of the relation is x ≥ . The range of the relation is y ≥ .
Answer:
[tex]x\geq 0[/tex] Domain
y = 40+1.5x relationship
[tex]y \geq 40[/tex] range
Step-by-step explanation:
The domain is the amount of carpet installed. We can install zero carpeting or any positive amount of carpeting.
[tex]x\geq 0[/tex]
Now writing the equation for the cost
They charge 40 flat rate plus 1.50 per square foot
y = 40+1.5x
Let x = 0
y = 40+0
Even if they do not install anything, they still charge 40 dollars flat rate. That is the minimum amount we have to pay. As x increases, the cost will increase.
That is the range, or the values of y
[tex]y \geq 40[/tex]
We want to get the equation for the total cost and its domain and range.
The equation is:
c(x) = $40 + $1.50*x
domain: x > 0ft^2
range: y > $40.
First, let's get the equation.
We know that the carpet installer charges a flat rate of $40 plus $1.50 per square feet.
So if he/she works for x square feets, the cost is:
c(x) = $40 + $1.50*x
This is the cost equation.
Now we want to find the domain and range of this. The domain is given by the possible values of x that we can input in the function. Here we know that x must represent the number of square feet that are worked on, so it only must be a number larger than zero.
x > 0ft^2.
While the range is the set of the possible outputs.
The smallest possible output is the one we get when we evaluate the function in the smallest value of the domain, so we get:
y > $40.
These two define the domain and range.

The perimeter of a rectangle is 15x + 17y
If the length is 7/2x + 7y then find the width of the rectangle.
Answer choices:
A. 4x + 3/2y
B. 8x + 3y
C. 8x + 10y
D. 4x + 3y
The width of the rectangle, given its perimeter and length, is calculated using the formula for the perimeter of a rectangle. By reorganizing the terms and isolating the width, we find that the width is 4x + 3/2y, which is Answer Choice A.
Explanation:The perimeter of a rectangle is given as 15x + 17y. The length is provided as 7/2x + 7y. To find the width, we need to remember that the perimeter of a rectangle is twice the sum of its length and width (P = 2l + 2w). Let's denote the width of the rectangle as 'w'.
So, the equation representing the perimeter is:
15x + 17y = 2(7/2x + 7y) + 2w
Now let's multiply out the factors on the right side:
15x + 17y = 2(7/2x) + 2(7y) + 2w
15x + 17y = 7x + 14y + 2w
To find 'w', we need to move all terms involving 'w' to one side of the equation and all other terms to the other side:
2w = 15x + 17y - (7x + 14y)
2w = 15x - 7x + 17y - 14y
2w = 8x + 3y
Divide throughout by 2 to find 'w':
w = 4x + 3/2y
The width of the rectangle is 4x + 3/2y, which corresponds to Answer Choice A.

Samantha and her children went into a grocery store and she bought $7 worth of bananas and peaches. Each banana costs $0.40 and each peach costs $0.50. She bought a total of 15 bananas and peaches altogether. Determine the number of bananas and the number of peaches that Samantha bought.
Answer:
10 peaches and 5 bananas
Step-by-step explanation:
To solve the problem increase the cost by adding more peaches and less by adding more bananas
7 peaches = 3.50
8 bananas = 3.20 + 3.50 = 6.70
We need 30 more cents so add three more peaches
10 peaches = 5
5 x 0.4 = 2
2 + 5 = 7
Final answer:
To determine the number of bananas and peaches Samantha bought, we can set up a system of equations and solve for the variables. By using substitution, we find that Samantha bought 5 bananas and 10 peaches.
Explanation:
To determine the number of bananas and peaches that Samantha bought, we can set up a system of equations. Let x represent the number of bananas and y represent the number of peaches. From the given information, we know the cost of each banana is $0.40 and the cost of each peach is $0.50. We can write two equations to represent the total cost of the bananas and peaches:
$0.40x + $0.50y = $7 (equation 1)
x + y = 15 (equation 2)
To solve this system of equations, we can use substitution or elimination. Let's use substitution:
From equation 2, we know that x = 15 - y. We can substitute this value of x into equation 1:
$0.40(15 - y) + $0.50y = $7
Simplifying the equation, we get:
$6 - $0.40y + $0.50y = $7
Combining like terms, we have:
$0.10y = $1
Dividing both sides by $0.10, we get:
y = 10
So, Samantha bought 10 peaches. Substituting this value of y back into equation 2, we can solve for x:
x + 10 = 15
Subtracting 10 from both sides, we get:
x = 5
Therefore, Samantha bought 5 bananas and 10 peaches.
