Step-by-step explanation:

1.

central (arc) angle is twice the inscribed angle (at the arc).

127° = 2A

angle A = 127/2 = 63.5°

2.

the full circle are 360°.

127° are arc angle CT, that leaves

360 - 127 = 233° for the arc angle C A T.

3.

the central angle at O opposite of the indicated 96° angle is (due to the rules of intersecting lines) also 96°.

the triangle M-O-A is an isoceles triangle (because both legs are a radius of the circle).

that makes angles A and M equally sized.

as the sum of all angles in a triangle is always 180°,

angle A = angle M = (180 - 96)/2 = 84/2 = 42°

4. see 3.

5.

the sum of all angles around one point on one side of a line is also always 180° (they represent a half-circle).

so, the top and the bottom angle at O are supplementary to the 96° angle (together they have 180°).

so, each is 180 - 96 = 84°

that means

arc angle M N A = 84 + 96 + 84 = 264°

6.

arc angle A F = 95°

arc angle A N = 103°

therefore, arc angle F N = 360 - 103 - 95 = 162°

as explained in 1.

angle A = arc angle F N/2 = 162/2 = 81°

7.

the triangles J-E-N and J-A-N have the same inscribed angle at the arc.

angle A = angle E (I cannot read the number at E).

8.

arc angle J A N + arc angle JN = 360

arc angle J N = 2× angle E

arc angle J A N = 360 - 2× angle E (again the number there is unreadable to me).

9.

again the inscribed angle at the arc is half of the opposite arc angle.

angle Y = arc angle T A / 2 = 70/2 = 35°.

10.

we have the arc angles S Y (134°) and T A (70°).

the 2 missing arc angles to make the whole circle are equally large due to T S and A T being equally long.

so,

arc angle S T = (360 - 134 - 70)/2 = 156/2 = 78°

Answer: To find out how many days it will take for the family to pay off their credit card balance, we can use the following equation:

Days = (-300) / 33

Solving for Days gives us:

Days = (-300) / 33 = -9

So it will take the family 9 days to pay off their credit card balance, assuming they only spend money on essential items and don't add any more to their debt.

Step-by-step explanation:

The previous balance in the account is equivalent to $68.303.

Given is that in August, Billy Quinlin deposited a total of $724 into his checking account. He wrote $585.27 in checks, had a service charge of $29.00 and earned $10.00 in interest. If his current balance is 239.46.

Assume that the initial cost was ${x}. So the total cost after depositing $724, the total amount will be ${x + 724}.

Total amount withdrawn = $585.27 + $29 = $614.27

Amount earned after interest -

10% of 614.27

(10/100) x 614.27

$61.427

Now, we can write -

{x + 724} - {614.27} + {61.427} = {239.46}

{x + 724} + {61.427} = {239.46 + 614.27}

x + 785.427 = 853.73

x = 853.73 - 785.427

x = 68.303

Therefore, the previous balance in the account is equivalent to $68.303.

The required difference in time taken by bob and sam is 0.8 hour.

Speed is defined as. The rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.

Bob can drive 50 miles in 40 minutes.

So, Speed of bob = 50×60/40 = 75 miles/hour

And Sam can drive 90 miles in 105 minutes.

Speed of Sam = 90×60/105 = 51.4 miles/hour

Now/

Time taken by bob(d) = 120/75 = 1.6

Similarly,

Time taken by Sam(e) = 120/51.4 = 2.4

The system of equations can have an infinite number of solutions when the equations are equivalent.

A system of equations can have infinitely many solutions when the equations are equivalent, meaning that the equations are identical when one is subtracted from the other. When this happens, the system of equations is said to have an infinite number of solutions. To solve a system of equations by elimination with infinitely many solutions, the equations must first be rearranged so that the same variable terms are on one side and the constant terms are on the other. Then, the coefficients of one variable must be made equal by multiplying one or both equations by a constant. After this, the equations can be added together or subtracted from one another and the variable terms will cancel out. This will result in an equation with only the constant terms, which is equivalent to 0=0. This equation is true for all values of the variables, so the system of equations has an infinite number of solutions.

The measure of angle ∠WDY is 89° in problem 20.

Two rays (half-lines) that share an endpoint make up an angle. The rays serve as the angle's sides, occasionally serving as the angle's legs and occasionally serving as its arms, while the latter is referred to as the vertex of the angle.

Two angles are said to be congruent by this definition if either of their vertex and side coordinates can be rigidly moved to coincide with the other. The angle may be written as AOB or BOA if O is the vertex and A and B are the points on the two sides (and this for any selection of the two points A and B.)

Given that D is the common point of line segments DW, DX and DY

m∠WDX = 2x - 5

m∠XDY = 52

m∠WDY = 5x - 16

to find m∠WDY

m∠WDY = m∠XDY + m∠WDX

5x - 16 = 52 + 2x - 5

5x - 2x = 52 - 5  + 16

3x = 63

x = 63/3

x = 21

m∠WDY = 5(21) - 16

m∠WDY = 89

Thus, the measure of angle ∠WDY is 89° in problem 20.

The probability of a randomly chosen divisor of [tex]$11!$[/tex] being prime is [tex]$\frac{32}{3^{2}\cdot2^{10}} = \frac{1}{243}$[/tex].

The prime factorization of [tex]$11!$[/tex] is 11!=[tex]11\cdot10\cdot9\cdot8\cdot7\cdot6\cdot5\cdot4\cdot3\cdot2\cdot1$[/tex], so there are [tex]$(2+1)(1+1)(1+1)(1+1)(1+1)(1+1)(1+1)(1+1)(1+1)(1+1) = (3^{2})(2^{10})$[/tex] divisors of  [tex]$11!$[/tex]

The prime divisors of  [tex]$11!$[/tex] are [tex]$2,3,5,7,11$[/tex], and there are [tex]$(1+1)(1+1)(1+1)(1+1)(1+1) = 2^{5} = 32$[/tex] divisors that are prime.

So the probability of a randomly chosen divisor of  [tex]$11!$[/tex] being prime is [tex]$\frac{32}{3^{2}\cdot2^{10}} = \frac{1}{243}$$[/tex]

A common fraction is a way of representing a ratio of two integers, where the numerator (the top part) represents the number of "favorable outcomes" and the denominator (the bottom part) represents the total number of possible outcomes.

In this case, the favorable outcome is a randomly chosen divisor of 11! being prime, and the total number of possible outcomes is the total number of divisors of 11! which is[tex]$(3^{2} )(2^{10})$[/tex]. So the probability of a randomly chosen divisor of 11! being prime can be represented as a common fraction by writing [tex]$\frac{32}{3^{2} \cdot2^{10}}$[/tex], with 32 as the numerator and [tex]$(3^{2})(2^{10})$[/tex] as the denominator.

II.             x + 3y = 180°                       -----(2)

On subtracting eq (1) from (2) we get

               2y=90°

                 y=45°

Now, From eq (1)

                x + y = 90°  

                 x = 90° - 45°

                 x = 45°

-4x  + 4x + 1 = 6x + 4x -9

1 = 10x - 9  Add 9 to both sides

1 + 9 = 10x - 9 + 9

10 = 10x  Divide both sides by 10

[tex]\frac{10}{10}[/tex] = [tex]\frac{10x}{10}[/tex]

1 = x

substitute 1 for x in either of the two original equations to solve for y

y = -4x + 1

y = -4(1) + 1

y = -4 + 1

y = -3

Check

y = -4x + 1

-3 = -4(1) + 1

-3 = -4 + 1

The probability that their total completion time in the maze for all rats is between 6 and 8 minutes is 0.375, or 37.5%.

The probability that their total completion time in the maze for all rats is between 6 and 8 minutes can be calculated using the Binomial Distribution formula. The formula is P = (nCr) * (p^r) * (1-p)^(n-r), where n is the number of trials, r is the number of successes, and p is the probability of success.

In this case, n = 4 (4 rats), r = 2 (completion time between 6 and 8 minutes), and p = 0.5 (50% chance of success). Therefore, P = (4C2) * (0.5^2) * (1-0.5)^(4-2) = 0.375.

The nucleus is at the center where the protons and neutrons are arranged. This is supported by his three models: the Rutherford model, the Bohr model and the (now accepted) quantum model.

So the red sphere and the two overlapping spheres in the middle represent protons and neutrons.

The line labeled A with the sphere in brackets represents the nucleus, as it signals both protons and neutrons within the nucleus.

The green blurry circular clouds represent the regions where electrons reside. This is blurry according to the quantum model, which states that the electrons are not in a fixed position, but in the region around the atom. This area is called the trajectory. According to the model, the electron's exact position cannot be determined, which means a blurry cloud.

This white line, which in Bohr's model should be circular where the electrons are, represents the electron orbits and shells identified by the letters L, M, N, and K. The first shell was the L shell.

In the quantum model, this line corresponds to the principal quantum number n (principal energy level). Therefore, the lines leading to brackets overlapping the white lines indicate the main energy levels.
