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.
y=(x+3)(x-2)(x-r) with a y int. of 24. solve for r?
Answer:
Step-by-step explanation:
To solve for r, you need to first find the values of x that make y equal to 24. These values of x are called the roots of the polynomial equation y = (x+3)(x-2)(x-r).
To find the roots of the equation, you can use the quadratic formula:
x = (-b +/- sqrt(b^2 - 4ac)) / (2a)
where a, b, and c are the coefficients of the quadratic equation y = ax^2 + bx + c.
In this case, the coefficients are:
a = 1
b = -3
c = -24
Substituting these values into the quadratic formula, we get:
x = (3 +/- sqrt(9 - 96)) / 2
= (3 +/- sqrt(-87)) / 2
Since sqrt(-87) is not a real number, there are no real roots for this equation. Therefore, the value of r cannot be determined.

LMNP is a rectangle. Find the value of x and the length of each diagonal.
The value of x is equal to 3.
The length of diagonal LN is equal to 18 units.
The length of diagonal MP is equal to 15 units.
What is a diagonal?In Mathematics, the diagonal of a rectangle can be defined as a line segment that connects any two (2) of its non-adjacent vertices together while dividing the rectangle into two (2) equal parts.
This ultimately implies that, the length of each diagonal of a rectangle is always equal to each other. Therefore, the diagonals of any rectangle is always equal to one other.
How to determine the value of x?We would determine the value of x by equating the length of each diagonal as follows;
LN = MP
7x - 3 = 4x + 3.
7x - 4x = 3 + 3
3x = 6
x = 6/2
x = 3.
Next, we would calculate length of each diagonal as follows;
LN = 7x - 3
LN = 7(3) - 3
LN = 21 - 3
LN = 18 units.
MP = 4x + 3.
MP = 4(3) + 3.
MP = 12 + 3
MP = 15 units.

Find the area. The figure is not drawn to scale.
Find the volume of the sphere shown. Give each answer rounded to the nearest cubic unit.
Answer:
[tex](a)\ Area = 28.12cm^2[/tex]
[tex](b)\ Volume = 1437.33cm^3[/tex]
Step-by-step explanation:
Solving (a): The parallelogram
[tex]h = 7.6[/tex] --- height
[tex]b = 3.7[/tex] --- base
The area is calculated usng:
[tex]Area = base * Height[/tex]
[tex]Area = 3.7 * 7.6[/tex]
[tex]Area = 28.12cm^2[/tex]
Solving (b): The sphere
[tex]d = 14cm[/tex]
Required
The volume
First, calculate the radius
[tex]r = d/2[/tex]
[tex]r = 14cm/2 = 7c,[/tex]
The volume is calculated using:
[tex]Volume = \frac{4}{3} \pi r^3[/tex]
This gives:
[tex]Volume = \frac{4}{3} * \frac{22}{7} * 7^3[/tex]
[tex]Volume = \frac{4}{3} * 22 * 7^2[/tex]
[tex]Volume = \frac{4}{3} * 1078[/tex]
[tex]Volume = \frac{4*1078}{3}[/tex]
[tex]Volume = \frac{4312}{3}[/tex]
[tex]Volume = 1437.33[/tex]
Find the sum of all solutions to the equation $4x(x-3) = 23$.
I NEED THIS ASAP
The sum of the solutions of the equation 4x(x - 3) = 23 is 3.
What is a quadratic equaton?A quadratic equation is an algebraic expression in the form of variables and constants.
A quadratic equation has two roots as its degree is two.
Given, An equation 4x(x - 3) = 23.
Now, Distributing the terms in the LHS we have,
4x² - 12x = 23.
4x² - 12x - 23 = 0.
By applying Sridhar acharya's formula we have,
[tex]x_{1,\:2}=\frac{-\left(-12\right)\pm \sqrt{\left(-12\right)^2-4\cdot \:4\left(-23\right)}}{2\cdot \:4}[/tex].
[tex]x=\frac{3+4\sqrt{2}}{2},\:x=\frac{3-4\sqrt{2}}{2}[/tex].
Therefore, The sum of the solutions of the equation is,
x + x = (3 + 4√2)/2 + (3 - 4√2)/2.
= (3 + 4√2 + 3 - 4√2)/2.
= 6/2.
= 3.

From the question, we have the following parameters that can be used in our computation:
Variation = direct variation
3y + 2 = 2x
A direct variation is represented as
y = kx
Where k is the constant of proportion
When the equations y = kx and 3y + 2 = 2x are compared, we can see that
The equation 3y + 2 = 2x has a constant term

What is a remainder
A remainder is the remaining amount of a number than comes out of a division. I'm not sure how to explain it better, so I'll give you an example:
Let's say you want to divide 5 by 2. We know that 5 can't be divided by 2 evenly, it won't give you a whole number. Instead it will give you a decimal 2.5.
In this case, 1 is the remainder and I will explain why! Do the long division for 5/2. 2 fits into 5 two times, so you multiply 2 * 2, which gives you 4. If you subtract that number from 5, you get 1. We know that 2 can't fit into one, therefore, 1 is the remainder. once you start getting into decimals, you can fit numbers into other numbers, which is why technically you can fit 2 into 5, but you can't fit it in evenly, if that makes sense!
I hope this example helps see what a remainder is. It's just the number in a long division that the divisor (in my example, 2 is the divisor) can't fit in!

The amount earned In a month is 3250.
There are 12 months In a year.
The total month in 10 years = 10× 12 = 120 months
The total amount in the account for 10years = 120×3250 = 390,000
