the sum of two digit number and the number obtained by reversing its digit is 154 if the digit differ from 4 find the number
Answer:
The number is either 95 or 59
Step-by-step explanation:
The two digit number would be;
(10a + b)
The reversal will be (10b + a)
The sum of the two is 154
(10a + b ) + (10b + a) = 154
11a + 11b = 154
11(a + b) = 154
a + b = 14 ••••••••(i)
The difference between the two digits is 4
Let’s have this as;
a - b = 4 ••••(ii)
from ii;
a = 4 + b
Substitute this into equation i
4 + b + b = 14
2b = 14-4
2b = 10
b = 10/2
b = 5
Recall;
a = b + 4
a = 5 + 4
a = 9
So we have the number as 95 or 59

Answer:
A hexagon has 6 internal angles, and the sum of the interior angles is 720°
If the hexagon is regular, so all the internal angles are equal, the measure of each internal angle is:
720°/6 = 120°
Ok, now let's look at the image.
We can "craft" a triangle rectangle. such that one cathetus is the line of 4ft that we can see in the image.
The hypotenuse is the line that connects the center, with the bottom right vertex.
Half of the bottom side is the other cathetus.
Because the hypotenuse divides the vertex in exactly two halves, the bottom right angle of the triangle rectangle will be 120°/2 = 60°.
So of this triangle rectangle, we know:
one angle equal to 60°
The opposite cathetus of this angle, which measures 4 ft.
Let's find the other cathetus of the rectangle:
We can use the identity:
Tan(a) = (opposite cathetus)/(adjacent cathetus)
In this case, we have:
Tan(60°) = 4ft/x
The value of x is:
x = 4ft/Tan(60°) = 4ft/√3
Because Tan(60°) = √3
And we know that the area of a triangle rectangle is the product of the length of each cathetus divided by two.
Then the area of our triangle rectangle is:
A = (4ft*4ft/√3)/2 = (8/√3) ft^2
And there are 12 of these right triangles inside the hexagon
Area = 12* (8/√3) ft^2 = (96/√3) ft^2
And we can write:
96 = √(96*96) = √9216
Then:
Area = √(9216/3) ft^2 = √(3072) ft^2

To the nearest cubic centimeter, what is the volume of the regular hexagonal prism? 3 cm 8 cm 2.6 cm The volume of the regular hexagonal prism is about nothing (Do not round until the final answer. Then round to the nearest whole number as needed.)
The volume of the given hexagonal prism is 187.2 cm³.
What is a hexagonal prism?A hexagonal prism is a prism with a hexagonal base and top. It is a 3D shape and thus, is a polyhedron with 8 faces, 18 edges, and 12 vertices. As it has 8 faces, it is also called an octahedron.
Given that, a hexagonal prism we need to find the volume,
So, the volume = 3 apothem × base × height
= 3 × 3 × 8 × 2.6
= 187.2
Hence, the volume of the given hexagonal prism is 187.2 cm³.

Step-by-step explanation:
The general approach is ...
find the area to be paintedfigure the amount of paint requireddetermine the discounted cost of the paint1. The area to be painted will be the area of the four walls, less the area of the door (which is assumed to be a hole in the wall, so is not painted).
Each wall has the same dimensions, so the same area. The area of the rectangular wall is ...
A = LW
A = (3.5 m)(2.6 m) = 9.1 m²
The area of the door is ...
A = (2.2 m)(0.8 m) = 1.76 m²
Then the area to be painted is the area of the 4 walls less the area of the door:
painted area = 4(9.1 m²) -1.76 m² = 34.64 m²
__
2. Each 2 L tin of paint will cover (2 L)×(8 m²/L) = 16 m², so the number of tins needed is ...
(34.64 m²)/(16 m²/tin) = 2.165 tins
We assume this means Aisha will need to purchase 3 tins, since she will need more paint than is provided by 2 tins.
__
3. Because of the price offer on the paint, Aisha will pay full price for the first two tins, half price for the 3rd tin. That is, she will pay 2 1/2 times the full price of a tin when she buys the 3 tins of paint she needs. Each tin costs £11, so Aisha will pay ...
(2 1/2)(£11) = £27.50
Aisha will pay £27.50 for the paint to paint her living room.

What is the vertex of y=x2 – 2x + 3?
O (-1,3)
O (1, 2)
O (3, 1)
O (2, -1)
Answer:
vertex = (1, 2 )
Step-by-step explanation:
Given a quadratic in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
y = x² - 2x + 3 ← is in standard form
with a = 1, b = - 2 , then
x = - [tex]\frac{-2}{2}[/tex] = 1
Substitute x = 1 into the equation for corresponding value of y
y = 1² - 2(1) + 3 = 1 - 2 + 3 = 2
vertex = (1, 2 )

Answer:
A

Given :
f(x) = ³√[ x - 9 ]And we need to find the inverse of the given function. We can do it by Firstly Interchanging x and y.
So that ,
[tex]:\implies[/tex] f(x) = y
[tex]:\implies[/tex] y = ³√[ x - 9 ]
[tex]:\implies[/tex] x = ³√[ y - 9 ]
[tex]:\implies[/tex] x³ = y - 9
