3004¢ more does Company B charge for x miles than Company A.

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

here, we have,

Company A charges ​$35.50 and 9¢ per mile.

Company B charges ​$65.50 and 13¢ per mile.

Also, we could convert dollars to cents by multiply it by 100

Since $1 =100 cents.

so, we get,

Company A charges ​$35.50 and 9¢ per mile. = 3559

Company B charges ​$65.50 and 13¢ per mile = 6563

difference =  6563 - 3559

                 = 3004

Hence, 3004¢ more does Company B charge for x miles than Company A.

Answer:

x=8

Step-by-step explanation:

We can first take out 3(x-5) and expand it into: (3*x) + (3*-5) = 3x-15

Now, let's plug it into the original equation:

3x-15-7 = 2

Let's solve for x:

3x = 2+15+7

3x = 24

x = 8

The diameter of the circle is 24 units.

In geometry, the circle is a curved and closed polygon whose boundary line is at equidistance from a point called the center.

A diameter is a line drawn through the circle's center and joining two points on its circumference. The diameter of a circle is twice its radius

The circumference of a circle is known as the circle's perimeter and is the distance a circle travels around its boundary line.

The formula for the circumference of a circle is given by

Here we have

The circumference of a circle is 75.4 units

Let 'r' be the radius of the circle

As we know Circumference of a circle = 2πr    

=> 2πr = 75.4

=> 2r(22/7) = 75.4

=> 2r = (75.4 × 7)/22  

=> 2r = [527.8]/22

=> 2r = 23.99

The probability that a defective part went through an electronic inspection is 0.2058 or approximately 20.58%.

In order to find the probability that a defective part went through an electronic inspection, Bayes' Theorem will be used. The theorem states that the conditional probability of event A given event B can be calculated as:

P(A | B) = P(B | A) × P(A) / P(B)

where P(A) is the prior probability of event A, P(B | A) is the conditional probability of event B given event A, and P(B) is the overall probability of event B.

In this case, event A is the part that went through an electronic inspection, and event B is the part that is defective. The prior probability of a part going through an electronic inspection is:

P(A) = 0.15, and the overall probability of a part being defective is P(B) = 0.15 ×  0.97 + 0.85 ×  (1 - 0.15) = 0.14695.

The conditional probability of a part being defective given it went through an electronic inspection is P(B | A) = 0.03. The probability of a part that went through an electronic inspection given it's defective is:

P(A | B) = P(B | A) ×  P(A) / P(B) = 0.03 ×  0.15 / 0.14695 = 0.2058

So, the probability that a defective part went through an electronic inspection is 0.2058 or approximately 20.58%.

Step-by-step explanation:

Please note that this question is incorrect.  

I assume the question is missing an "x" term, since log₉27 ≠ -3.

Let's assume 27 should be "x":

[tex]\implies \log_9x=-3[/tex]

[tex]\implies x=9^{-3}[/tex]

If, however, the 9 is supposed to be "x":

[tex]\implies x^{-3}=27[/tex]

Given exponential equation:

[tex]\implies x^{\frac{1}{2}}=256[/tex]

Given logarithmic equation:

The simplest form of the polynomial is (x²)-3x+1.

A polynomial is a mathematical expression consisting of constants, variables, and exponents. It can be written in the form of a polynomial equation, which is a mathematical equation with one or more variables.

In this example, we have two functions, f(x) and g(x). The polynomial of these two functions can be written in simplest form by combining the functions together.

The polynomial of f(x) and g(x) is written in simplest form as (x²)-3x+1.

This means that for any value of x, the polynomial will evaluate to the value given by the equation.

If x=2, then the polynomial will evaluate to (2(2)²)-3(2)+1=3.

No, AA Criterion should not be called the AAA Criterion, because we need only two angles to be equal to prove the similarity.

According to the AA triangle similarity criterion, two triangles are considered similar if their three angles are identical to one another. Equi-angular triangles are comparable in a nutshell.

Since just two pairs of angles must be equal in order for the third pair to be automatically equal thanks to the angle sum property of triangles, the proper term for this criterion would then be the AAA(Angle-Angle-Angle) criterion. However, we refer to it as the AA criterion instead.

Hence, no, because we need only two angles to be equal to prove the similarity.

Answer: The friends should choose the Raft Trip if they want to spend exactly $29.

The equation for the Raft Trip is 6n + 5 = 29. Solving for n, we get n = 4. This means that 4 people can participate in the Raft Trip for $29.

The other two activities, the Amusement Park and the Balloon Ride, have equations 14n = 29 and 30n + 40 = 29, respectively. Solving these equations, we find that neither of them allow exactly 4 people to participate for $29.

Step-by-step explanation:

The activity the friends should choose if they want to spend exactly $29 is Raft Trip

Number of people in the group= 4

Raft Trip:

6n + 5 = 29

6(4) + 5 = 29

24 + 5 = 29

Amusement Park:

14n = 29

14(4) = 29

56 ≠ 29

Balloon Ride:

30n - 40 = 29

30(4) - 40 = 29

120 - 40 = 29

80 ≠ 29

Therefore q + d = 60

Since each quarter is 25 cents(or $0.25) and each dime is 10 cents($0.10)

Total value = 0.25q + 0.10d = 13.35

Step-by-step explanation:

length = width + 6

the perimeter of a rectangle is

2×length + 2×width

by using the first equating as identity in the second we get

36 = 2×(width + 6) + 2×width =

= 2×width + 12 + 2×width = 4×width + 12

24 = 4×width

width = 6 m

length = width + 6 = 6 + 6 = 12 m

he dimensions of the rectangular room are 6 meters by 12 meters of the rectangular room is 6 meters longer than it is wide, and its perimeter is 36 meters by solving equations and geometric measurements.

Given that the room is 6 meters longer than it is wide, we can represent the width as W. Therefore, the length of the room would be W + 6.

The perimeter of a rectangle is calculated by adding all four sides, which in this case is given as 36 meters. We can express this as an equation:

Perimeter = 2 * (Length + Width)

Substituting the values, we get:

36 = 2 * (W + (W + 6))

Simplifying the equation further, we have:

36 = 2 * (2W + 6)

Dividing both sides of the equation by 2, we get:

18 = 2W + 6

Subtracting 6 from both sides, we obtain:

12 = 2W

Dividing both sides by 2, we find:

W = 6

Now that we have the width, we can calculate the length:

Length = Width + 6 = 6 + 6 = 12

Therefore, the dimensions of the rectangular room are 6 meters by 12 meters of the rectangular room is 6 meters longer than it is wide, and its perimeter is 36 meters by solving equations and geometric measurements.
