What is the angle?
An angle is a figure in Euclidean geometry made up of two rays that share a common endpoint and are referred to as the angle's sides and vertex, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
Given that m∠EBF = 60°, m∠EBG = 2m∠EBF
The m∠EBF is the sum of the angles and the angles are m∠EBG and m∠EBF.
Therefore,
m∠EBF = m∠EBG + m∠EBF
Putting m∠EBF = 60° and m∠EBG = 2m∠EBF in aboue equation:
60° = 2m∠EBF + m∠EBF
3m∠EBF = 60°
Divide both sides by 3:
∠EBF = 20°.
12.
Given that, m∠ABE = 64°.
From the diagram, m∠ABD = m∠DBE.
The m∠ABE is the sum of the angles and the angles are m∠ABD and m∠DBE.
m∠ABE = m∠ABD + m∠DBE
64° = 2m∠DBE
Divide both sides by 2:
m∠DBE = 32°
13.
Given that, m∠GBH = 28°.
From the diagram, m∠GBH = m∠HBC.
m∠HBC = 28°.

use the properties of logarithms to expand the following expression. logy7xz3
The expanded logarithmic expression is 7log y + log x + 3log z.
The use of a logarithm can be utilised to solve issues that cannot be resolved using the concept of exponents alone. A logarithm is simply another way to describe exponents. Log interpretation is not that tough. It suffices to know that an exponential equation can also be written as a logarithmic equation in order to comprehend logarithms.
Exponent and logarithm are inverses of one another. This is explained in the section below. John Napier, a mathematician, first developed logarithms as a technique to perform computations simply, and other scientists, engineers, etc. immediately embraced this idea.
The given logarithmic equation is:
log ([tex]y^{7}xz^{3}[/tex])
Now, we can use the properties of logarithms to expand this fully.
log (abc) = log a + log b+ log cTherefore,
log ([tex]y^{7}xz^{3}[/tex]) = log ([tex]y^{7}[/tex]) + log (x) + log ([tex]z^{3}[/tex])
log (a²) = 2log aTherefore,
log (y⁷) = 7 log y
log (z³) = 3 log z
Therefore, the expanded logarithmic expression is 7log y + log x + 3log z.

The square shape wall whose length is 10m has a door of length 2m and breadth 1m. It also has a window of length 1m and breadth 0.5m. What will be the cost of painting the wall at Rs.5 per meter.
The cost of painting the wall is Rs.48.75 .
How to find the cost to paint the wall?The square shape wall whose length is 10m has a door of length 2m and breadth 1m. It also has a window of length 1m and breadth 0.5m.
Therefore, the cost of painting the wall can be calculated as follows:
cost of painting per meters = Rs0.5 per metre square
Therefore, the area of the wall to be painted will exclude the window and the door.
Hence,
area of wall of the wall to be painted = area of the wall - area of the window - area of the door
Therefore,
area of wall of the wall to be painted = 10² - (1 × 0.5) - (2 × 1)
area of wall of the wall to be painted = 100 - 0.5 - 2
area of wall of the wall to be painted = 97.5 metres²
Therefore,
1 metres square = Rs0.5
97.5 metres squared = ?

solve the equation z2 z 1 = 0 for z = (x,y) by writing (x,y)(x,y) (x,y) (1,0) = (0,0)
The solutions of x = 0 or x = y and y = 0 or y = 1 can then be found. Therefore, the solutions of the equation are (0,0), (0,1), (1,0), and (1,1).
x2 - xy + y2 - x = 0
x(x - y) + y(y - 1) = 0
x(x - y) = 0 and y(y - 1) = 0
x = 0 or x = y and y = 0 or y = 1
Therefore, the solutions are (0,0), (0,1), (1,0), and (1,1).
The equation z2 z 1 = 0, when written as (x,y)(x,y) (x,y) (1,0) = (0,0), can be manipulated to x2 - xy + y2 - x = 0. By factoring out the x and y terms, the equation can be rearranged to x(x - y) + y(y - 1) = 0. This then can be further simplified to x(x - y) = 0 and y(y - 1) = 0. The solutions of x = 0 or x = y and y = 0 or y = 1 can then be found. Therefore, the solutions of the equation are (0,0), (0,1), (1,0), and (1,1).

For the function P = 3x + y, there is no solution present to maximize it.
What is a function?
In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.
The given objective function -
P = 3x + y
Subjected to the constraints -
5x + 7y ≥ 35
3x + 4y ≤ 12
x ≥ 0, y ≤ 0
First consider the inequality 5x + 7y ≥ 35.
The equation of the above inequality is as follows -
5x + 7y = 35
Find two points that satisfies the above equation.
Take x = 0, then -
5(0) + 7y = 35
7y = 35
y = 5
The first point is (0,5).
Take y = 0, then -
5x + 7(0) = 35
5x = 35
x = 7
The second point is (7,0).
Substitute (x,y) = (0,0) and see the direction of the region for 5x + 7y ≥ 35.
5(0) + 7(0) ≥ 35
0 ≥ 35
This is not true.
Therefore, the region is non-origin side.
Now consider the inequality 3x + 4y ≤ 12.
The equation of the above inequality is as follows -
3x + 4y = 12
Find two points that satisfies the above equation.
Take x = 0, then -
3(0) + 4y = 12
4y = 12
y = 3
The first point is (0,3).
Take y = 0, then -
3x + 4(0) = 12
3x = 12
x = 4
The second point is (4,0).
Substitute (x,y) = (0,0) and see the direction of the region for 3x + 4y ≤ 12.
3(0) + 4(0) ≤ 12
0 ≥ 12
This is true.
Therefore, the region is origin side.

a. squares with sides of length x are cut out of each corner of a rectangular piece of cardboard measuring 3 ft by 4 ft. the resulting piece of cardboard is then folded into a box without a lid. find the volume of the largest box that can be formed in this way.
The largest box that can be formed has a volume of 20 cubic feet.
Let's call the side length of the square cutout x. The original piece of cardboard measures 3 feet by 4 feet, so the dimensions of the piece of cardboard after the cutouts are made are (3 - 2x) by (4 - 2x).
When this piece is folded into a box, the length and width of the box will be (3 - 2x) and (4 - 2x) respectively. The height of the box will be x, as that is the height of the cutout squares.
The volume of the box can be found by multiplying the length, width, and height: V = (3 - 2x)(4 - 2x)x
We want to find the maximum volume, so we need to differentiate the expression for the volume and set it equal to zero, and then solve for x.
dV/dx = 2x(4 - 2x) - (3 - 2x)(2x) = 0
2x(4 - 2x) = (3 - 2x)(2x)
2x(4 - 2x) = 2x^2 - 6x^2
-4x^2 + 4x = 0
x(4 - x) = 0
x = 0 or x = 4
Since the side length of the cutout square cannot be negative, we reject x = 0 and keep x = 4. So, the maximum volume will occur when the side length of the cutout squares is 4 feet.
Substituting x = 4 into the expression for the volume, we find:
V = (3 - 2x)(4 - 2x)x = (3 - 2x)(4 - 2x) = (3 - 2x)(4 - 2x) = (3 - 8)(4 - 8) = -5 * -4 = 20 cubic feet
So, the largest box that can be formed has a volume of 20 cubic feet.
Therefore, The largest box that can be formed has a volume of 20 cubic feet.

where ρ is the resistivity of the material, ℓ is the length of the conductor, and a is the cross-sectional area.
From Ohm's Law, we can also derive an expression for the electric field inside the conductor:
E = V/ℓ = IR/ℓ = ρI/a
In the case of conductors 1 and 2, the voltage across both conductors is the same (v2 = v1), so the electric field in conductor 2 can be expressed as:
E2 = V2/ℓ2 = v1/(2ℓ1) = ρI2/a2 = (ρ/2a1)I2
Similarly, the electric field in conductor 1 can be expressed as:
E1 = V1/ℓ1 = v1/ℓ1 = ρI1/a1 = (ρ/a1)I1
Finally, the ratio of the electric fields in conductors 1 and 2 can be calculated as:
E2/E1 = (ρ/2a1)I2 / (ρ/a1)I1 = a1/2a1 = 1/2
So, the ratio of the electric fields, E2/E1, is equal to 1/2. This means that the electric field in conductor 2 is half the electric field in conductor 1, despite the fact that the voltage across both conductors is the same. This happens because the cross-sectional area of conductor 2 is twice that of conductor 1, which compensates for the fact that the length of conductor 2 is also twice that of conductor 1.

Ted says that the triangle below cannot be classified because all sides are different lengths. Is Ted correct? Explain why or why not.
Answer:
he is not because triangles can be different sides but they always have to equal 180 if it's a right triangle but if it does not it's a ln acute or obtuse triangle
a group of eight kids lines up in random order. each ordering of the kids is equally likely. there are five girls and three boys in the group. what is the probability that all the boys are ahead of all the girls?
Using the arrangements formula, it is found that there is a 0.0178 = 1.78% probability that all the girls are ahead of all the boys.
The number of possible arrangements of the n elements is the factorial of n, that is:
[tex]A_{n} = n![/tex]
The total number of outcomes is the arrangement of 8 elements, hence:
T = 8! = 40320
The desired number of outcomes is all-girls(5!), then all-boys(3!), hence:
D = 5! × 3! =120× 6=720
Hence, the probability is:
p = D/T =720/40320 = 0.0178
There is a 0.0178 = 1.78% probability that all the girls are ahead of all the boys.
