2 red and 2 overlapping balls in the center are surrounded by a green, fuzzy, circular cloud with a white line running through it. 2 green balls sit on the white line, and a line leading a bracket around the balls is labeled A. A line leading to a bracket overlapping the white line is labeled B.Identify the parts of the atom that are labeled in the diagram.
They describe a model of an atom with two protons, two neutrons, electron density (orbitals), and two electrons. Now suppose we want to know what the labels A and B stand for.
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.
Atoms are neutral because they contain as many electrons as protons around the nucleus.

Supposed a family has a credit card balance of -300 ($300 of debt) they spend an average of $33 a day on essential items
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.

The required difference in time taken by bob and sam is 0.8 hour.
What is Speed?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.
According to question: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

Solve using substitution y=-4x+1 y=6x-9
Answer:
x = 1
y = -3
(1,-3)
Step-by-step explanation:
Set the 2 equations equal to each other and solve for x
-4x + 1 = 6x - 9 Add 4x from both sides
-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

y = 6x - 9

what is the probability that their total completion time in the maze for all rats is between 6 and 8 minutes
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.
This means that 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%.

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

Need help. Use each given circle O. Find the indicated measures
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°

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

How do you solve a system of equations by elimination infinitely many solutions?
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.

= 3y
According to Question:
I. x + y = 90° -----(1)
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°
∴ The angle is 45°
