To calculate the number of gallons of gasoline required, you need to know the energy consumption of the car in MJ and the distance of the trip.

The first step is to determine the energy consumption of the car in MJ per unit distance (e.g. per mile or per kilometer). This information can be obtained from the car's fuel consumption specifications or from real-world tests.

Once the energy consumption is known, the number of gallons of gasoline required for a given trip can be calculated by dividing the total energy consumption of the trip by the energy content of a gallon of gasoline (120 MJ). This will give you the number of gallons of gasoline required to make the trip.

The total cost of the taxi ride is given by the equation A = $ 19.25

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total cost of taxi ride be represented as A

Now , the equation will be

The initial cost for the pickup = $ 3.50

The cost of the ride per mile = $ 1.75

The cost for riding 9 miles = 9 x cost of the ride per mile

Substituting the values in the equation , we get

The cost for riding 9 miles = 9 x 1.75 = $ 15.75

So , the total cost of taxi ride A = initial cost for the pickup + cost for riding 9 miles

The total cost of taxi ride A = 3.50 + 15.75

The total cost of taxi ride A = $ 19.25

So , if the ride is m miles long , the cost is A = 3.50 + ( 1.75 )m

Hence , the equation is A = $ 19.25

The standardized value for x = 2.69 is 0.

The standardized value (z) is given by:

z = (x - mean) / standard deviation

where x is the value to be standardized, mean is the normal distribution's mean, and standard deviation is the normal distribution's standard deviation.

So, for x = 2.69, with a mean of 2.69 and a standard deviation of 4.76, the standardized value (z) is:

z = (2.69 - 2.69) / 4.76 = 0

As a result, the standardized value for x = 2.69 is 0.

Standard deviation is a measure of the spread or dispersion of a set of data values around their mean (average). It provides a quantitative indication of how far apart each data value is from the mean and from each other. A low standard deviation means that the data values are close to the mean, while a high standard deviation indicates that the data values are more spread out.

Answer:

The value 0.031 represents the interest rat, which means the annual compounded interest rate is 3.1%

First option

Step-by-step explanation:

The general equation for amount accrued A with a principal P at an annual compound interest rate of i%(r/100 in decimal) compounded n times a year for t years is given by

[tex]A = P\left(1 + \dfrac{r}{n}\right)^{nt}[/tex]

Here r = i/100 which is a decimal

Looking at the specific equation
[tex]A = 2400\left(1 + \dfrac{0.031}{4}\right)^{4t}[/tex]

we can see that P = 2440, the initial investment

0.031 is the annual interest rate in decimal

Expressed as percentage that would be 0.031 x 100 = 3.1% per year

So the correct answer is the first option which states
The value 0.031 represents the interest rat, which means the annual compounded interest rate is 3.1%

The composite figure is made up of a trapezium and a quarter of a circle, so we shall calculate for the areas of the two figures and then add the result to get the total area of the composite figure as follows:

area of the trapezium = [(6 + 10)/2] yd × 8 yd

area of the trapezium = (16/2) yd × 8 yd

area of the trapezium = 8 yd × 8 yd

area of the trapezium = 64 yd²

area of circle = πr²

area of circle = 22/7 × 3 × 3

area of circle = 198/7

a quarter area of the circle = 198/7 ÷ 4

a quarter area of the circle = 7.07 square yard

total area of the composite figure = 64 yd² + 7.07 yd²

The circumference of the circle is 6.28 .

Circle is a closed figure or curve that we get by drawing a line which passes through the points which are at an equal distance from a common point.

Perimeter of a closed figure is the total length of the line used for making that closed figure.

For example if we have three sticks of Length 2 cm, 3 cm, 5 cm. We make a triangle using the above sticks so the perimeter of the triangle will be

       = 2+3+5= 10 cm

This indicates that total length of stick used to form the triangle is 10 cm.

For a circular figure its perimeter is known as circumference.

Now for the given question:

Diameter of the circle ( D ) = 2 yards.

π= 3.14         ( given in question)

Circumference of a circle = π×D

                                          = 3.14×2

11) The two column proof below has been used to prove that EI ⊥ KT

A two-column proof is defined as a geometric proof that consists of a list of statements, and the reasons that we know those statements are true.

9) We want to prove that EG bisects HF.

In a rectangle opposite sides are equal and parallel.

In ΔMHE and ΔMFG, ∠MEH = ∠MGF

[Alternate interior angles; HE ∥ GF and EG as transversal]

HE = GF [Opposite sides of a rectangle are equal]

∠MHE = ∠MFG

[Alternate interior angles; HE ∥ GF and HF as transversal]

Thus;

ΔMHE ≅ ΔMFG

[By ASA congruence rule]

Equating the corresponding parts of congruent triangles, we get:

HM = FM

GM = EM

Diagonals of a rectangle bisect each other.

The gross elasticity of demand for car polish with respect to the price of a car wash is 3.

The elasticity of demand refers to the change in demand when there is a change in another economic factor, such as price or income.

Given that, Sparkle clean car decreased the price of a car wash from $12 to $9 and noticed that the weekly quantity demanded for car polish increased from 200 to 350.

We are asked to find elasticity of demand,

First, we will find the increase in the customers:

Customer increasing = 350 - 200 / 200 × 100

= 75

Now, the fluctuation in the price =

Price fluctuation = 12 - 9 / 12 × 100

= 25

Elasticity = increased rate / fluctuated price

= 75 / 25

= 3

The elasticity of demand is 3 which is greater than 1, so, that mean, the demand is elastic.
