The speed of each train is 125kph and 145kph.

Here it is given that the distance between the two trains is 810 miles after traveling for 3 hours.

The difference in their speed is 20 kph.

Let x be the speed of one train. So by this, we get the speed of the second train that is x + 20.

Formula to calculate speed is:

Speed = Distance / Time

Distance = Speed × Time

Distance covered by first train = x × 3

Distance covered by second train = (x + 20) × 3

Total distance = 810

So we get;

3x + (x + 20)3 = 810

3x + 3x + 60 = 810

6x = 750

x = 125

x + 20 = 125 + 20 = 145

Therefore we get the speed of both trains which is 125kpp and 145 kph.

Answer:

The circumference of a semi-circle can be calculated using the formula:

Circumference of a semi-circle = (π × diameter)/2We have a diameter of 26.5 in, and we need to find the circumference of the semi-circle. Therefore, the circumference of the semi-circle is:

Circumference of a semi-circle = (π × 26.5)/2= (3.14 × 26.5)/2= 41.6075 in (rounded to 42 to the nearest hundred)

Therefore, the circumference of the semi-circle with a diameter of 26.5 in is approximately 42 in (rounded to the nearest hundred).

The minimum number of boxes a participant needs to eliminate is 12. The half chance of holding at least $100,000 as his/her chosen box is 7/14 from the whole chances of 7/26.

There are 26 boxes.

The required money is at the 7 the stage box.

So, the chance of holding at least $100,000 is 7/26.

Since the required value is available at a 7/26 chance of holding, the boxes that are less than $100,000 are removed.

So, 12 boxes holding less than $100,000. So, the probability of half chance of holding at least $100,000 is 7/14.

Transfomation 1: the function will undergo vertical shrinking( by a factor of 0.

5)

Transformation 2: the function is shifted 2 units up

Explanation

Step 1

the first transformation is the function multiplied by a constant ( 1/2)

If the function is multiplied by a value less than one, all the values of the equation will decrease, leading to a “shrunken” appearance in the vertical direction

so

Transfomation 1: the function will undergo vertical shrinking( by a factor of 0.

The given expressions, when A=1, B=0, and C=1, X evaluates to 1.001; when A=B=C=1, X evaluates to 1.111; and when A=B=C=0, X evaluates to 0.000. These evaluations are based on the given values of A, B, and C, and the notation ¯¯¯¯¯¯BC represents the complement of BC.

To evaluate the expression X = A.¯¯¯¯¯¯BC, we substitute the given values of A, B, and C into the expression.

(a) For A = 1, B = 0, and C = 1:

X = 1.¯¯¯¯¯¯01

To find the complement of BC, we replace B = 0 and C = 1 with their complements:

X = 1.¯¯¯¯¯¯01 = 1.¯¯¯¯¯¯00 = 1.001

(b) For A = B = C = 1:

X = 1.¯¯¯¯¯¯11

Similarly, we find the complement of BC by replacing B = 1 and C = 1 with their complements:

X = 1.¯¯¯¯¯¯11 = 1.¯¯¯¯¯¯00 = 1.111

(c) For A = B = C = 0:

X = 0.¯¯¯¯¯¯00

Again, we find the complement of BC by replacing B = 0 and C = 0 with their complements:

X = 0.¯¯¯¯¯¯00 = 0.¯¯¯¯¯¯11 = 0.000

In conclusion, when A = 1, B = 0, and C = 1, X evaluates to 1.001. When A = B = C = 1, X evaluates to 1.111. And when A = B = C = 0, X evaluates to 0.000. The evaluation of X is based on substituting the given values into the expression A.¯¯¯¯¯¯BC and finding the complement of BC in each case.

The diver collected water samples at every 3 meters, starting from 5 meters below the water surface, up to a final depth of 35 meters.

We can find the number of samples collected by dividing the total depth range by the distance between each sample and then adding 1 to include the first sample.

The total depth range is:

35 m - 5 m = 30 m

The distance between each sample is 3 m, so the number of samples is:

(30 m) / (3 m/sample) + 1 = 10 + 1 = 11

Therefore, the diver collected a total of 11 water samples.

Answer:

n = - 11

The displacement of the compressor is 628 cubic centimeters. Other factors that affect the performance of a compressor include its operating pressure, flow rate, efficiency, and power consumption.

To find the displacement of the compressor, we need to use the formula:
Displacement = (pi/4) x bore^2 x stroke
Here, the bore is 8 centimeters and the stroke is 10 centimeters. So, substituting these values in the formula, we get:
Displacement = (pi/4) x 8^2 x 10
Displacement = (3.14/4) x 64 x 10
Displacement = 628.32 cubic centimeters

A compressor is a mechanical device that is used to increase the pressure of a gas or air by reducing its volume. It works by compressing the gas or air in a cylinder and then transferring it to a storage tank or other equipment. The displacement of a compressor is a measure of the volume of gas or air that is displaced or compressed during one complete cycle of the compressor. Therefore, the displacement of the compressor is 628 cubic centimeters. This means that during one complete cycle of the compressor, it displaces or compresses 628 cubic centimeters of gas or air. The displacement is an important parameter of a compressor, as it determines its capacity or the amount of gas or air that it can compress in a given time.

To find the displacement of the compressor, we first need to understand what displacement means. Displacement is the change in position of an object in a specific direction. In this case, the compressor has a bore of 8 centimeters and a stroke of 10 centimeters. The displacement of the compressor can be calculated as the product of the bore area (πr^2) and the stroke length.

Displacement = π(4^2) * 10 = 16π * 10 = 160π cubic centimeters.

Therefore, each bus can hold 22 students if there were 12 students per van.

In mathematics, an equation is a statement that asserts the equality of two expressions. Equations typically contain one or more variables, which are symbols that can represent different values. Solving an equation means finding the value or values of the variable(s) that make the equation true.

Here,

a) Let V be the number of vans and B be the number of buses. We know that there were 8 vans and 12 buses, so we can write:

V + B = 20 (the total number of vehicles)

We also know that there were 360 students in total. If we assume that each van can hold 12 students, and each bus can hold some number of students, we can write:

12V + bB = 360 (the total number of students)

where b is the number of students that each bus can hold.

b) We can use the equation we derived in part a) and substitute V = 8 to solve for B:

V + B = 20

8 + B = 20

B = 12

So there were 12 buses in total. We can then use the equation 12V + bB = 360 and substitute V = 8 and B = 12 to solve for b:

12V + bB = 360

12(8) + b(12) = 360

96 + 12b = 360

Answer:

To find the slope of the parallel and perpendicular lines to the equation y = 3/4x + 4, we need to use the fact that parallel lines have the same slope, while perpendicular lines have opposite reciprocal slopes.

The given equation is in slope-intercept form, y = mx + b, where m is the slope of the line and b is the y-intercept.

Therefore, the slope of the given line y = 3/4x + 4 is 3/4.

To find the slope of a line parallel to this one, we know that it must have the same slope. Therefore, the slope of the parallel line is also 3/4.

To find the slope of a line perpendicular to this one, we need to take the opposite reciprocal of the slope. The opposite reciprocal of 3/4 is -4/3. Therefore, the slope of the perpendicular line is -4/3.

In summary, the slope of the parallel line is 3/4, and the slope of the perpendicular line is -4/3.
