There are 198 passengers in each car.

What is division?

The division is one of the four basic mathematical operations of arithmetic, along with addition, subtraction, and multiplication. It is the inverse operation of multiplication.

To determine the number of passengers in each car, we need to divide the total number of passengers by the total number of cars.

We know that:

There are 4,752 passengers in total

There are 8 cars per train and 3 trains

So, the total number of cars is 8 cars/train x 3 trains = 24 cars

To find the number of passengers per car, we divide the total number of passengers by the total number of cars:

4,752 passengers / 24 cars = 198 passengers per car.

Hence, there are 198 passengers in each car.

Yes, the numbers 2 and 9 are co-prime numbers, i.e., HCF(2,9) = 1.

Two numbers a and b are relatively prime if their only common divisor is 1. If the only highest common factor of two numbers a and b is 1, then a and b are co-prime numbers. In this case,(a, b) is said to be a co-prime pair. Properties of relatively prime numbers:

We have, two numbers say 2 and 9 and we have to check they are co-prime or not. The factors of 2 are 1 and 2. Factors of 9 are 1, 3 and 9. So, highest common factor between 2 and 9 is 1. As 9 and 2 have no common factor other than 1, they are co-prime.

What is slope ?

Slope, also known as gradient, is a measure of the steepness of a line. It is the ratio of the change in the y-coordinate to the change in the x-coordinate between any two distinct points on the line. It is represented by the letter "m" in the slope-intercept form equation of a line y = mx + b, where m is the slope, x is the independent variable, y is the dependent variable and b is the y-intercept, the point where the line crosses the y-axis.

The slope of a line is a measure of its steepness or incline. It is the ratio of the change in the y-coordinate (rise) to the change in the x-coordinate (run) between two points on the line.

There are several methods that can be used to solve a system of nonlinear equations, but three common ones are: substitution method, elimination method and graphing method.

Substitution method: This involves isolating one variable in one equation and substituting it into the other equation to eliminate that variable. You can then solve for the remaining variable and substitute it back into the original equation to find the solution.

Elimination method: This method involves adding or subtracting the equations in such a way as to eliminate one of the variables. Then you can solve for the remaining variable and substitute it back into the original equation to find the solution.

Graphical method: This method involves graphing both equations on the same coordinate plane and finding the point of intersection of the two lines. The coordinates of this point will be the solution to the system of equations.

here (x₁, y₁ ) = P (1, 6 ) and (x₂, y₂ ) = Q (5, 10 ) , then

midpoint = ( [tex]\frac{1+5}{2}[/tex], [tex]\frac{6+10}{2}[/tex] ) = ( [tex]\frac{6}{2}[/tex] , [tex]\frac{16}{2}[/tex] ) = (3, 8 )

Answer:

x = 39

m ∠1 = 63°

m ∠2 = 117°

Step-by-step explanation:

m∠1 + m∠2 = 180° since they are adjacent linear angles lying on the same straight line

Therefore x + 24 + 3x = 180

4x + 24 = 180

4x = 180-24 = 156

x = 156/4 = 39

Therefore x = 39 (a)

FOr (b) substitute this value of x = 39 into each equation

m∠1 = x + 24 = 39 + 24 = 63°

m∠2 = 3x = 3(39) = 117°

To find the factored form of the quadratic equation x^2 + 8x + 16, we can use the technique of factoring by grouping.

First, we write the equation in the form of (x^2 + ax + b) + (x + c) = 0

x^2 + 8x + 16 = 0

Next, we find two numbers that multiply to b and add to a, in this case, b = 16 and a = 8

We can factor out a common factor of x from the first two terms and x + 4 from the last two terms: x^2 + 8x + 16 = (x^2 + 8x) + (16)

Finally, we can factor out a common factor of x + 4 from both terms:

x^2 + 8x + 16 = x(x + 8) + 4(4)

So the factored form of x^2 + 8x + 16 is (x+4)^2.

You can also find the factored form of the quadratic equation x^2 + 8x + 16 by using the difference of squares method:

x^2 + 8x + 16 = (x+4)^2

It's worth noting that this is a perfect square trinomial, which means that it can be factored into the square of a binomial.

Hence, the value of u is -69.

The volume of solid₁ and solid₂ is related with y = x + 1 where x = 1 × 2 units.

The amount of actual space a 3D object takes up is measured by its volume. It represents the area in three dimensions of a two-dimensional shape. It is measured in cubic units like cm3, for example. This can be determined by multiplying the object's length, height, and width.

Based on a fundamental equation, which is one of the first equations that students encounter in school, this method of measuring volume was developed. Because it lays the foundation for further equation study, math volume is very important.

We cane see that

y = x + 1

1/2 of 2 = x/2 = 1

x = 2

Lets find the value of the variables

y = (2)+ 1

y = 3

Volume of solid₁ = x × y × 2 = 2 × 3 × 2 = 12 cube unit

Volume of solid₂ = x × y × 2 = 2 × 3 × 2 = 12 cube unit

Thus, the volume of solid₁ and solid₂ is related with y = x + 1 where x = 1 × 2 units.

Julie is approximately 40.6 ft away from the base of the tower.

Trigonometry is a branch of mathematics that deals with the relationships between the angles and sides of triangles. One of the main uses of trigonometry is to calculate distances in a triangle when the lengths of two sides and the measure of the angle between them are known.

We can calculate this by using the formula:

Distance = (tower height) / (tan(angle of depression))

Distance = (83 ft) / (tan(49))

Distance = 40.6 ft (rounded to the nearest tenth)

Answer:

Domain: is -4 ≤ x ≤ 1
which can be expressed in interval notation as

[-4, 1]

Range is -3 ≤ y ≤ 2

or in interval notation: [-3, 2]

Step-by-step explanation:

The domain is the set of x values from minimum to maximum

The range is the set of y values again from minimum to maximum

Minimum value of x = -4

Maximum value = 1

So range is -4 ≤ x ≤ 1 which can be expressed in interval notation as

[-4, 1]

Minimum y-value is -3 and maximum y-value is 2

Range is -3 ≤ y ≤ 2

It will take 20.6 hours to paint the house if both painter A and painter B worked together.

Proportions are defined as the concept where two or more ratios are set to be equal to each other.

Suppose we have two ratio p : q and r : s.

If both these ratios are proportional, then we can write it as p: q : : r : s.

This is same as p : q = r : s or p/q = r/s

Let F represent the house fully painted.

Painting done by painter A in 50 hours = F

Painting done by painter A in 1 hour = F/50

Painting done by painter B in 35 hours = F

Painting done by painter B in 1 hour = F/35

If they both paint together,

Painting done by painter A and painter B in 1 hour = F/50 + F/35

                                                                                    = 85/1750 F

                                                                                    = 17/350 F

Time taken to paint 17/350 F = 1 hour

Time taken to paint F = 1 / (17/350)

                                    = 20.588

                                    ≈ 20.6 hours

Hence time taken to paint the house by both working together is 20.6 hours.

The factor of 9x² 24xy 16y² is (3x−4y)²

A number or other mathematical object is factorized or factored when it is written as the product of numerous factors, usually smaller or simpler things of the same kind.

Factorization in mathematics is the method of dividing a large number into tiny ones that, when multiplied together, give you the original number. Factorization is the split of a number into its factors or divisors.

9x²−24xy+16y²

=(3x)²−24xy+(4y)²

=(3x)²−2(3x)(4y)+(4y)²

Using (a−b)²=a²−2ab+b², we get
