Answer:
49200 rs. so the cost of flooring =246*200=49200 rs
Step-by-step explanation:
we measure the area of veranda by taking width in addition of length and breadth- house area
it means
area of veranda =outer rectangle-inner rectangle
⇒area= (20+3+3)*(15+3+3)-20*15
⇒area=26*21-300
⇒area= 546-300
⇒area=246 m²
Hence , the cost of flooring =246*200=49200 rs.

The members of a consulting firm rent cars from three rental agencies. It is estimated that 0.42 percent of cars come from agency 1, 0.08 percent of cars come from agency 2, and 0.5 percent of cars come from agency 3. It is also estimated that 0.08 percent of cars from agency 1 need a tune-up, 0.02 percent of cars from agency 2 need a tune-up, and 0.02 percent of cars from agency 3 need a tune-up. Answer the following questions, rounding your answers to two decimal places where appropriate.
The probability that a rental car delivered to the firm will need a tune-up is 0.05% and the conditional probability is 0.04%
How to determine the probabilitiesThe probability that a rental car delivered to the firm will need a tune-up
From the question, we have the following parameters that can be used in our computation:
Agency 1 = 0.42%, Tune up from agency 1 = 0.08%
Agency 2 = 0.08%, Tune up from agency 2 = 0.02%
Agency 3 = 0.5%, Tune up from agency 3 = 0.02%
Using total probability, we have the following equation
P(tune-up) = P(tune-up | agency 1) * P(agency 1) + P(tune-up | agency 2) * P(agency 2) + P(tune-up | agency 3) * P(agency 3)
Substitute the known values in the above equation, so, we have the following representation
P(tune-up) = 0.08% * 0.42% + 0.02% * 0.08% + 0.02% * 0.5%
Evaluate the sum of products
P(tune-up) = 0.000452
Express as percentage and approximate
P(tune-up) = 0.05%
(b) The probability that it came from agency 2
This is a conditional probability, and it calculated as
P(Agency 2| Tune up) = P(Tune up and Agency 2)/P(Tune up)
Substitute the known values in the above equation, so, we have the following representation
P(Agency 2| Tune up) = (0.02% * 0.08%)/0.0452%
Evaluate
P(Agency 2| Tune up) = 0.0003539823
Express as percentage
P(Agency 2| Tune up) = 0.03539823%
Approximate
P(Agency 2| Tune up) = 0.04%
So, the probability is 0.04%

Using the collected data above what would be a reasonble rough estimate of a ratio of how many cubic inches per orange?
given the farmer's market wanted o use a box that had the dimensions, approximately how many oranges should fit?
The ratio is 17.14 cubic inch per orange and 168 oranges for given dimensions.
What is volume?In three dimensions, everything takes up some space. What is being measured here is the area's volume. The volume of an object is the area occupied inside its three-dimensional boundaries. It is referred to as the object's capability on occasion.
The amount required to fill an object can be determined by finding its volume, for example, how much water is required to fill a bottle, aquarium, or water tank.
Given
dimensions of box 20 x 13 x 12, 12 x 12 x 12 and 20 x 10 x 6
volume of box 1 = 20 x 13 x 12 = 3120 cubic inches
volume of box 2 = 1728 cubic inches
volume of box 3 = 20 x 10 x 6 = 1200 cubic inch
oranges in box 1 = 96
oranges in box 2 = 53
oranges in box 3 = 37
and radius of orange = 32./2 = 1.6 inches
volume of each orange = 4/3πr³
volume of each orange = 4/3(3.14)(1.6)³
volume of each orange = 4/3(3.14)(4.096)
volume of each orange = 17.14 cubic inches
here one orange will cover 17.14 cubic inches.
7. let the dimension of box is 15 x 12 x 16
volume of box is = 15 x 12 x 16 = 2880 cubic inches
the number of oranges in box will be 2880/17.14 = 168 oranges
Hence there will be 17.14 cubic inch per orange volume is covered, and 168 oranges will be in box for given dimensions.

am is paying off his eight-year, $15,360 loan in semiannual installments. The loan has an interest rate of 9.58%, compounded semiannually, and a service charge of $1,294.64. Once the loan has been fully paid off, what percentage of the total finance charge will the service charge be? Round all dollar values to the nearest cent.
a.
5.48%
b.
8.43%
c.
18.55%
d.
15.65%
Please select the best answer from the choices provided
A
B
C
D
The percentage of the total finance charge on the loan that the service charge will be is about 15.65%. Option D is correct.
D. 15.56%
What is a loan?A loan is an item borrowed for a charged amount, such as an amount borrowed to be repaid with a specified interest fee.
The compound interest formula for the semiannual interest rate is presented as follows;
A = P·[1 + R/n]^(n·t)
Where;
P = The initial amount borrowed on loan = $15,360
t = The interest rate on the loan = 9.58% = 0.0958
n = The number of periods in a year = 2 for semiannual interest rate
t = The duration of the loan = 8 years
The equal semi annual installment (ESI) formula is presented as follows;
[tex]ESI = P\times \dfrac{\dfrac{r}{2} \times\left(1 + \dfrac{r}{2} \right)^n }{\left(1+\dfrac{r}{2} \right)^n-1}[/tex]
Therefore;
ESI = 15360 × ((0.0958/2)×(1 + 0.0958/2)¹⁶)/((1 + 0.0958/2)¹⁶-1) ≈ 1396.16
The total amount Sam pays = 16 × 1396.16 ≈ 22338.6
The finance charge ≈ 22338.6 - 15360 = 6978.6
The percentage of the finance charge represented the service charge is therefore;
(1294.64/(6978.6 + 1294.64))×100 ≈ 15.65%
The percentage of the total finance charge represented by the service charge is therefore about 15.65%

solve in vertex form?
In algebra, the vertex form of a quadratic equation is a way of expressing the equation in the form:[tex]y = a(x - h)^2 + k[/tex]
where (h, k) is the vertex of the parabola defined by the equation. The value of 'a' determines whether the parabola opens up or down and the value of 'h' and 'k' determine the position of the vertex on the coordinate plane.
For example, the standard form of a quadratic equation is:
[tex]y = ax^2 + bx + c[/tex]
To convert this to vertex form, you would first complete the square to get all the terms of x on one side of the equation and a constant on the other side. Then, you would put the equation in the form shown above.
So, given the equation [tex]y = 3x^2 + 6x - 4[/tex], we can complete the square to get:
[tex]y = 3(x^2 + 2x) - 4[/tex]
then rearrange it to
[tex]y = 3(x^2 + 2x + 1) -7 = 3(x+1)^2-10[/tex] which is in vertex form with vertex (-1,-10)
The vertex form of a quadratic function provides a convenient way to quickly identify the vertex of the parabola without having to complete the square every time.

When working with piping offsets, which are based on right triangles. Which of the following angle measurements will you see as a standard elbow angle? a. 22.5, b. 60, c. 70. d.45
Answer:
d. 45°
Step-by-step explanation:
You want to know which from your list is a standard elbow angle.
ElbowAn elbow is a pipe fitting that is used to change the direction of piping. Elbows can be used together to produce an offset and/or a change in the plane of the piping.
Standard elbow angles commonly are 90°, 45°, and, less commonly, 22.5°. The greater the angle, and/or the smaller the bend radius, the more resistance to flow it has.
The best choice of answer here is 45°.
__
Additional comment
The typical elbow has the same kind of threads on both sides. A "street elbow" has male threads on one side and female threads on the other side.
Elbow joints are not necessarily threaded. They may also be soldered, welded, or compression joints.
The volume of a rectangular box is x^3+x^2-4x-4 cubic inches. If the length of the box is x+1 inches and the width is x-2 inches, what is the height , in inches, off the box in terms of x
The volume of a rectangular box can be found by multiplying the length, width, and height of the box together. So if the volume of the box is x³+x²-4x-4 cubic inches, the length is x+1 inches, and the width is x-2 inches, we can set up the equation h = (x³+x²-4x-4) ÷ (x²-x-2).
The formula for the volume of a rectangular box is V = l × w × h, where l is the length, w is the width, and h is the height of the box. This formula can also be written as V = l×w×h.
In the question you provided, the volume of the rectangular box is given as x³+x²-4x-4 cubic inches, and the length and width are given as x+1 inches and x-2 inches, respectively. With this information, we can set up an equation using the formula for the volume of a rectangular box:
(x+1)(x-2)(h) = x³+x²-4x-4
where h is the height of the box in inches. To solve for h, we can divide both sides of the equation by (x+1)(x-2) to get:
h = (x³+x²-4x-4) ÷ (x+1)(x-2)
And Now we can simplify the expression using standard algebraic operations.
h = (x³+x²-4x-4) ÷ (x²-x-2)
You can now substitute any value of x to find the height of the box.

what is the percent of change for your grade if originally you got 5 questions right and you checked your work and ended up with 15 questions right
Answer:
To calculate the percent of change, you will need to find the difference between the original score and the revised score and divide that by the original score. Then, multiply the result by 100 to express the answer as a percentage.
In this case, the difference between the original score (5 questions right) and the revised score (15 questions right) is 10 questions. Dividing this by the original score of 5 questions gives you a result of 2. Multiplying this by 100 gives you a percent of change of 200%. This means that your revised score is 200% higher than your original score.

To prove the converse of the Pythagorean theorem, we can define a right triangle, Response area, with sides a, b, and x. Then, we will show that if △ABC is a triangle with sides a, b, and c where a² + b² = c², then it is congruent to △DEF and therefore a right triangle.
By the Pythagorean theorem, because △DEF is a right triangle, a² + b² = x².
If a² + b² = x² and a² + b² = c² , then c² = x². Further, since sides of triangles are positive, then we can conclude that c = x. Thus, the two triangles have congruent sides and are congruent.
If △ABC is congruent to a right triangle, then it must also be a right triangle.
To prove the converse of the Pythagorean theorem, we can define a right triangle Δ DEF with sides a, b, and x.

Please help with with the correct response and explanation if you can I would be more than thankful for some help!
Answer:
To solve this problem, you need to use the distributive property, which states that for any two numbers a and b, and for any numbers x and y, (a + b) * x = ax + bx and x * (a + b) = xa + xb.
Applying the distributive property, we have:
(-5i)(7 + i) = (-5i) * 7 + (-5i) * i
= -35i + (-5i) * i
Now, you need to use the fact that i * i = -1:
(-5i)(7 + i) = -35i + (-5i) * i
= -35i + (-5) * (-1)
= -35i - 5
= -40i - 5
So the final result is -40i - 5.

What is the inverse of the function [tex]y=x^{2} +4x+4[/tex]
Answer:
y = 2 ± √x is the inverse but it's not a function. (See note below for additional info)
Step-by-step explanation:
Given the quadratic function:
[tex] \displaystyle{y = {x}^{2} + 4x + 4}[/tex]
We can rewrite the function above using perfect square form:
[tex] \displaystyle{y = {(x + 2)}^{2} }[/tex]
Finding an inverse, we swap the terms of x and y:
[tex] \displaystyle{x = {(y + 2)}^{2} }[/tex]
Square root both sides, solving for y:
[tex] \displaystyle{ \sqrt{x }= \sqrt{ {(y + 2)}^{2}} } \\ \\ \displaystyle{ \sqrt{x }= \left| y+ 2\right| } \\ \\ \displaystyle{ \pm \sqrt{x }= y + 2}[/tex]
Subtract both sides by 2:
[tex] \displaystyle{ \pm \sqrt{x } - 2= y+ 2 - 2} \\ \\ \displaystyle{ \pm \sqrt{x } - 2= y} \\ \\ \displaystyle{y = 2 \pm \sqrt{x} }[/tex]
Therefore the inverse of y = x² + 4x + 4 is y = 2 ± √x.
Note: While it's possible to find the inverse of quadratic function, but the inverse version itself is not really a function. So if you want to go by definition or theorem, you can say there's no inverse function. Otherwise, the answer above is the solution.
