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

So,

d - e

|1.6 - 2.4|

0.8

Thus,required difference in time is 0.8.

The greatest number of elements that s can have is 2002, and the set s = {1,2,3,4,5,...,2002}

The property of the set s states that for every element x in s, the arithmetic mean of the set obtained by deleting x from s is an integer.

To understand this property, we can start by considering the case when the set s has only two elements, say x and y. In this case, the arithmetic mean of the set obtained by deleting x from s is y, and the arithmetic mean of the set obtained by deleting y from s is x. As both x and y are integers, this property holds true.

When the set s has three elements, say x, y, and z. The arithmetic mean of the set obtained by deleting x from s is (y+z)/2. as y and z are integers, (y+z) is always even, thus (y+z)/2 is always an integer. The same applies to the arithmetic mean of the set obtained by deleting y and z.

As we can see, this property holds true for any set of distinct positive integers, no matter the number of elements.

Given that 1 belongs to s and that 2002 is the largest element of s, we can use the property of the set to find the greatest number of elements that s can have.

The arithmetic mean of the set obtained by deleting 1 from s is (x+y+z+...+2002)/(n-1) = (x+y+z+...+2002)/n + 1/n. as x, y, z... 2002 are integers, (x+y+z+...+2002) is always an integer, thus (x+y+z+...+2002)/n is always an integer. Then, as 1/n is always an integer, (x+y+z+...+2002)/n + 1/n is always an integer.

Therefore, the greatest number of elements that s can have is 2002, and the set s = {1,2,3,4,5,...,2002}

At the 20th generation, 400 squares, 400 triangles, and 400 trapezoids are needed.

The pattern for the first through the fifth generations of squares, triangles, and trapezoids is that each generation is made up of the previous generation's shapes, but with each shape having an additional set of smaller shapes attached to each side.

For example, in the first generation, there is only one square. In the second generation, four smaller squares are attached to the sides of the first square. In the third generation, nine smaller squares are attached to the sides of each of the four squares in the second generation, and so on.

The number of shapes needed to create each generation can be found using the formula:

(n^2)

Where n is the generation number.

For example, in the first generation, only 1 square, 1 triangle and 1 trapezoid is needed, in the second generation, 4 of each are needed, in the third generation, 9 of each are needed, and so on.

If this pattern holds for each generation, the number of tiles required at the 20th generation can be found by substituting n = 20 into the formula:

(20^2) = 400

To determine if the generation you are building is similar (by mathematical definition) to the other generations, you would need to check whether the ratio of corresponding sides is the same for each shape in the generation.

When you double the dimensions of a given polygon, the area is multiplied by four. When you triple the dimensions of a given polygon, the area is multiplied by nine.

The pattern for the number of shapes needed to create each generation follows the pattern of a square of n^2. Therefore, the number of tiles required at the 20th generation can be found by substituting n = 20 into the formula, n^2 = 20^2 = 400.

Answer: 45°

Step-by-step explanation:

Let the angle be x and its complement be y

Also,

Complement = 1/3 × Supplement

So,

Supplement = 3 × Complement

                     = 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°

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.

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 rate of change of the radius is -9/(2π*99) inches/second.

The volume of a cylinder can be found with the equation V = πr^2h, where V is the volume, r is the radius, h is the height and π is a constant. We know that the volume is constant at 1318 cubic inches and we know that the height of the cylinder is increasing at a constant rate of 9 inches per second.

V = πr^2h

1318 = π * 99^2 * h

Now we can differentiate this equation with respect to time.

dV/dt = 2πr*dr/dt * h + πr^2 * dh/dt

where dV/dt is the rate of change of the volume, dr/dt is the rate of change of the radius and dh/dt is the rate of change of the height.

Now we know that dV/dt = 0, dh/dt = 9 and we know the value of r, we can substitute these values in the above equation and solve for dr/dt

0 = 2π * 99 * dr/dt * h + π * 99^2 * 9

dr/dt = -9/(2π*99) inches/second

The rate of change of the radius is -9/(2π*99) inches/second at the instant when the radius of the cylinder is 99 inches.
