The percentage of vehicles that have four wheels are trucks is 30%.

Percentage is defined as the parts of a number per fraction of 100. So the percentage actually means a part per 100.

Percentage is usually denoted by the symbol '%'.

Number of trucks that are four wheels = 127 - 76 = 51

Number of trucks that have more than four wheels = 76

Total number of trucks = 127

Number of non trucks that are four wheels = 120

Number of non trucks that have more than four wheels = 18

Total number of non trucks = 138

Total number of four wheels = 51 + 120 = 171

Number of trucks that are four wheels = 51

Percentage of vehicles that have four wheels are trucks = (51 / 171) × 100 = 29.82 ≈ 30%

Hence 30% of the for wheeler vehicles are trucks.

There are 16 possible values are there for the third side length.

In an acute triangle, the three angles are less than 90°.

The minimum length of the third side is if the other two sides form the lowest possible angle (close to 0 degrees), in which case the length approximates zero, so if the number is an integer, the minimum length of the third side is 1.

The maximum length of the third side is if it is close to the hypotenuse of a right triangle with legs 8 and 15 =>

hypotenuse² = 15² + 8² = 289 => hypotenuse =17. So, the length of the third side must be less than 17.

So, the possible lengths of the third side are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, and 16.

Step-by-step explanation:

The constant of proportionality in the equation in terms of cost per video is 2.

Option C is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x = 4 is an equation.

We have,

The cost of the video downloads (in dollars) is given by the equation.

c = 2v

where c is the total cost of the videos and v is the number of videos.

Now,

c = 2v can be written as,

c ∝ v

This means,

2 is the constant of proportionality.

Factorization is a step in the process of locating the roots of a quadratic equation.

Finding the roots of a quadratic equation involves the process of factorization. When factoring quadratic equations, the original quadratic expression is changed into the product of two linear factors.

A quadratic function has the formula f(x) = ax² + bx + c, with a, b, and c being integers and a not equal to zero. A parabola is a curve that represents the graph of a quadratic function. Parabolas can have openings that are upward or downward, different "widths" or "steepnesses," but they all share the same fundamental "U" shape.

Breaking down the factors, or numbers, that multiply to create another number is a frequent mathematics operation known as factoring. Various things affect some figures.

c) The probability of at most one lawn is: P(X ≤ 1) = 0.6.

The distribution, giving the probability of each outcome, is presented as follows:

The probability of at least one lawn is given as follows:

P(X > 0) = P(X = 1) + P(X = 2) + P(X = 3)

P(X > 0) = 0.4 + 0.3 + 0.1

P(X > 0) = 0.8.

The probability of at most one lawn is obtained as follows:

P(X ≤ 1) = P(X = 0) + P(X = 1)

The possible value of third side of triangle c lies between 9 and 25 by the triangle inequality theorem. 9 < c < 25 is correct.

According to triangle inequality theorem that, given two sides length of a triangle, the length of the third side of the triangle must be larger than the difference and smaller than the sum of the two given sides.

for two sides length a and b of a triangle and third side is c,

then according to triangle inequality theorem

(a-b) < c < (a+b)

in the given example we have two sides of triangle are 8 and 17.

let a=17

b=8 and unknown side is c

from triangle inequality theorem

The expressions that are equivalent to 25 + 3(a-5) + 7a are:

10a + 10, 5(2a + 2) and 2(5a + 5)

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we substitute the same value(s) for the variable(s).

The expression 25 + 3(a-5) + 7a can be written as follow:

25 + 3(a-5) + 7a = 25 + 3a -15 + 7a

                          = 10a + 10

Thus, 10a + 10 is equivalent to 25 + 3(a-5) + 7a

Since 5(2a + 2) =  10a + 10. Thus, 5(2a + 2) is equivalent to  25 + 3(a-5) + 7a

The cost of fencing the field if the cost of the mesh wire used is RM 20 per metre is RM 102000.

Area of the field = 5100 m²

Cost of the mesh wire used = RM 20 per metre

To calculate the cost of fencing the field, we need to multiply the area of the field by the cost of the mesh wire used, that is

Cost of fencing the field =  Area of the field × Cost of the mesh wire used

Cost of fencing the field = 5100  × RM 20

Cost of fencing the field = RM 102000

Mr. Morgan has to pay a state tax of $ 38.4 in a biweekly basis on his $42000 yearly income.

State income taxes are a proportion of your income that you pay to the state government based on how much money you earn from your work, and they vary from state to state.

Tax exemption is the reduction or elimination of a requirement to make a required payment that would otherwise be imposed on individuals, properties, income, or transactions by a ruling power. Tax-exempt status might offer full tax exemption, reduced rates, or tax on only some things.

The more children you have, the more taxes you pay since children are exemptions or deductions on tax forms. Some non-profit organizations are tax-exempt, which means they don't have to pay any taxes. People are also exempt from participating in certain vocations and battles. You are excused if you have an exemption.

Personal Exemption is non taxable = $ 3600

Total income = $ 42000 yearly

Total taxable income = 42000 - 3600 = $ 38400

Total tax yearly = 2.6 % of 38400 = (2.6/100)*38400 = $ 998.4

Answer (my view): If it's an inverse f(-1)(x) = 6^x/2

Explanation: The function is f(x) = log6(2x), an inverse of a function (i. e: f(-1)(x)) can be defined as a function that takes an output of it's main function (i. e: f(x)) as its input and returns the original input plotted in the main function. Any logarithm can be interpreted as an exponentiation, so log6(2x) would be equal to 6^f(x) = 2x, the function f(-1)(x) would take this exponent of 6 returned by the main function and return a half of the base of the function times 1/2, letting this exponent (output of the main function) be x, f(-1)(x) = 6^x/2.

Algebraically, however: f(x) = log6(2x), and f(f^(-1)(x)) = x.

So log6(2(f^(-1)(x))) = x, then 6^x = 2(f^(-1)(x)), (6^x)/2 = (f^(-1)(x)).
