Answer:
Step-by-step explanation:
let the height of the room(h) = x
Length(l) = 3*x = 3x
length = 2 * breadth
breadth(b) = length /2 = 3x/2
Cost of whitewashing the 4 walls = ₹ 7200
Area of 4 walls = 7200 ÷ 50 = 144 m² ------(I)
Area of walls = 2lh + 2bh
= 2*3x*x + 2 *[tex]\frac{3x}{2}[/tex] * x
= 6x² + 3x²
= 9x²
9x² = 144 {From (I)}
x² = 144/9
x² = 16
x = [tex]\sqrt{16}=\sqrt{4*4}[/tex]
x = 4 m
height = 4 m
length = 3*4 = 12m
Breadth = [tex]\frac{3}{2}*4=3*2=6 \ m[/tex]
Area of floor = l*b
= 12 * 6
= 72 m²
Cost of carpeting the floor = 72 * 325 = ₹ 23400

find y=? when x=7.
given that y varies directly with x.
y = kx
Where k is the constant of proportionality
k= y/x
k= (1/4)÷ 5
k= 0.05

Your classmate is unsure about how to use side lengths to determine the type of triangle. How would you explain this to your classmate?
Answer:
To determine the type of triangle using side lengths, you could use the converse of the Phythagorean theorem, acute triangle inequality theorem, and the obtuse inequality theorem. For example, if the square of the longest side of a triangle is greater than the sum of the squares of the other two sides, than its obtuse. And if the square of the longest side is less than the sum of the squares of the other two sides, then it would be acute. And if the square of the longest side is equal to the sum of the squares of the two other sides, then it would be a right triangle.

Solve the system of equations shown below.
Answer:
(6, 4 )
Step-by-step explanation:
Given the 2 equations
2x - 6y = - 12 → (1)
x + 2y = 14 → (2)
Multiplying (2) by - 2 and adding to (1) will eliminate x
- 2x - 4y = - 28 → (3)
Add (1) and (3) term by term to eliminate x
- 10y = - 40 ( divide both sides by - 10 )
y = 4
Substitute y = 4 into either of the 2 equations and solve for x
Substituting into (1)
2x - 6(4) = - 12
2x - 24 = - 12 ( add 24 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
solution is (6, 4 )

Answer:
Sides = 3.2
Diagonals = 4.5
Shape = Square
Step-by-step explanation:
a) i) Distance from P to Q= 3.162278 which is approx 3.2.
So to calculate your answer you use the distance formula. The formula is the square root of (x2 - x1) + (y2 - y1).
So all sides of the shape have a length of 3.2 because the shape is a square.
DIAGONALS:
QS = 4.472136 approx 4.5
For:
(X1, Y1) = (-3, -2)
(X2, Y2) = (-1, 2)
We use the same formula for distance.
B) The shape is a square

Can you please factor the problems below and explain/show all your steps. I will be attaching a photo with the problems as well in case they are more understandable on there. Also if you can please explain how you used the key concepts from the photo in your work if you used them.
Factor: 2a^3 + 4a^2 + 8a
Factor: 6y^4 - 294y^2
Factor: 5x^2 + 50x +125
---------------------------------------
To factor each expression, we apply the given concepts, that is, greatest common factor, difference of squares and perfect squares.
---------------------------------------
Expression 1:
The expression is:
[tex]2a^3 + 4a^2 + 8a[/tex]
First, we find the gcf of the numbers 2, 4 and 8, which is 2.
Of the exponents, the gcf between 3, 2 and 1 is 1, so:
[tex]2a^3 + 4a^2 + 8a = 2a(\frac{2a^3}{2a} + \frac{4a^2}{2a} + \frac{8a}{2a}) = 2a(a^2 + 2a + 4)[/tex]
---------------------------------------
Expression 2:
The expression is:
[tex]6y^4 - 294y^2[/tex]
The gcf of 6 and 294 is 6.
The gcf of the exponents 2 and 4 is 4.
Thus:
[tex]6y^4 - 294y^2 = 6y^2(\frac{6y^4}{6y^2} - \frac{294y^2}{6y^2}) = 6y^2(y^2 - 49)[/tex]
Then, applying the difference of squares:
[tex]y^2 - 49 = (y - 7)(y + 7)[/tex]
Thus, the factored expression is:
[tex]6y^2(y^2 - 49) = 6y^2(y - 7)(y + 7)[/tex]
---------------------------------------
Expression 3:
The expression is:
[tex]5x^2 + 50x + 125[/tex]
The gcf of the coefficients, 5, 50 and 125 is 5, so:
[tex]5(\frac{5x^2}{5} + \frac{50x}{5} + \frac{125}{5}) = 5(x^2 + 10x + 25)[/tex]
Applying the perfect square, we get that:
[tex]x^2 + 10x + 25 = (x + 5)^2[/tex]
Tus, the factored expression is:
[tex]5(x^2 + 10x + 25) = 5(x+5)^2[/tex]

The system of linear equations x – y + 2 = 0 and 2x + y -14 = 0
Answer:
(4, 6 )
Step-by-step explanation:
Given the equations
x - y + 2 = 0 ( subtract - y + 2 from both sides )
x = y - 2 → (1)
2x + y - 14 = 0 → (2)
Substitute x = y - 2 into (2)
2(y - 2) + y - 14 = 0 ← distribute and simplify left side
2y - 4 + y - 14 = 0
3y - 18 = 0 ( add 18 to both sides )
3y = 18 ( divide both sides by 3 )
y = 6
Substitute y = 6 into (1) for corresponding value of x
x = 6 - 2 = 4
solution is (4, 6 )

Answer:
40
Step-by-step explanation:
We can split this figure into two figures, a square and a trapezoid. The square, as shown has a side length of 4. That means that the area of the square is 16. The trapezoid, has base lengths of 2 and 4, and a height of 8. We can plug that into the area of a trapezoid formula:
[tex]\frac{2+4}{2}(8)[/tex]
Two plus 4 is 6, and 6 divided by 2 is 3. Three times 8 is 24.
24 plus 16 (the area of the square) is equal to 40, which is the area of the shape.
Which figure is described below?
The locus of points in a plane
equidistant between
(-5, -6) and (-5, 7).
Answer:
A.Line
Step-by-step explanation:
The locus of points in a plane equidistant between (-5, -6) and (-5, 7) is describe by the Line. so option A is correct.
What is a line segment?A line segment is a straight line with finite length, and thus, have to endpoints(points on either ends).
We know that the graph of x = 5 is the vertical line through 5 on the x-axis. Two points on this line are (-5, -6) and (-5, 7).
We form a horizontal line through (0,1) and (1,1). This is the locus of points equidistant between (-5, -6) and (-5, 7)
We have parallel lines like this, the locus of points equidistant from the two lines is always one single line, and it's the middle line as described above.
This applies to diagonal parallel lines as well, and vertical parallel lines.
Hence, The locus of points in a plane equidistant between (-5, -6) and (-5, 7) is describe by the Line. so option A is correct.

B. natural numbers

F. integers
Answer:
A
E
Step-by-step explanation:
a rational number can be expressed as fraction. well, that is what the number 8/9 is.
so, A is a correct option.
as such it is automatically also a member of the real numbers (which is a superset of rational numbers). so, E is a correct option.
all other options are wrong.
8/9 is not a natural number (1, 2, 3, 4, ...).
it is not a whole number (0, 1, 2, 3, 4, ...).
it is not an integer (... , -2, -1, 0, 1, 2, 3, ...).
and as it is a rational number, it is automatically not an irrational number.
