Step-by-step explanation:

Using linear functions, it is found that:

a. The equations are given by: H(x) = 30 + 0.79x, R(x) = 75 + 0.55x.

b. The costs will be the same after 187.5 miles.

c. The estimate from the graph is reasonable, as it is the value of x for which both equations are equal.

A linear function is defined according to the following rule:

y = mx + b

In which:

For each function in the context of this problem, we have that:

Hence the equations for each company are given as follows:

The graph is given at the end of the answer, and from the intersection point, we have that the costs will be the same after 187.5 miles.

Numerically, this value is given as follows:

H(x) = R(x)

30 + 0.79x = 75 + 0.55x

0.24x = 45

x = 45/0.24

x = 187.5.

Hence the estimate from the graph is reasonable.

The sum of the measures of all the angles in all of the triangles shown in the given diagram is 3,600°.

We need to find the sum of the measures of all the angles in all of the triangles shown in this diagram.

A triangle is a closed shape with 3 angles, 3 sides, and 3 vertices.

The sum of all the angles of the triangle is equal to 180°.

From the figure, by counting, we get there are 20 triangles.

As we know, the sum of all the interior angles of a triangle is 180°.

So, the sum of the measures of all the angles in all of the triangles = The number of triangles × 180°

= 20 × 180°

= 3,600°

Therefore, the sum of the measures of all the angles in all of the triangles shown in the given diagram is 3,600°.

The equation has infinite solutions is the last option:

6(x - 1) = 2*(3x - 3)

Any equation in which we can remove the variable has infinite solutions (because it does not depend on the value of x) only if the equation is true.

Let's look at the fourth equation:

6(x - 1) = 2*(3x - 3)

If we expand both sides, we will get:

6x - 6 = 2*3x - 2*3

6x - 6 = 6x - 6

So we have the exact same thing in both sides, if we remove 6x - 6 in both sides we will get:

0 = 0

Then this equation has infinite solutions.

The sequence given by the terms 125,25,5 is a geometric sequence with common ratio 1/5.

In a geometric sequence, each term following the first is found by multiplying the preceding one by a constant, non-zero quantity known as the common ratio.

The nth term of a geometric series with first term a and common ratio r is given by [tex]a_n=ar^{n-1}[/tex] .

In the given sequence, the first term denoted by a is 125. The second term is 25 and the third term is 5.

Ratio of the second term to first term = 25/125 = 1/5

And the ratio of third term to second term is = 5/25 =1/5

Hence since the ratios are equal therefore the sequence is geometric, and the common ratio is 1/5 .

Step-by-step explanation: That's just how it works. It's an algerbra rule. Hope that helped. Have a nice day.

Rule 1: The product of a negative integer and a positive integer is a negative integer. Rule 2: The product of two positive integers or two negative integers is a positive integer. That means if you multiply two OF the same sign numbers, the product is always positive.

The quotient of 1.843 × 10^7 and 4.85 × 10^4, expressed in scientific notation, is 3.8 × 10^2.

Scientific notation is a way of expressing a very large or a very small number that are too much to be written in decimal form. The scientific notation is represented as:

a × 10^b

where a is between 1 and 10 and b is an integer representing the number of zeros

To divide numbers in scientific notation,

1. Divide the decimal numbers.

1.843 ÷ 4.85 = 0.38

2. Subtract the exponents of your power of 10.

7 - 4 = 3

3. Place the new power of 10 with the decimal in scientific notation form.

On the map, the separation between the two towns would be 5 cm.

Detailed explanation:

First, consider 2 cm and 30 miles as a ratio, which means that wherever you measure 2 cm with a ruler on a map, 30 miles will be scaled to that location.

Then, using some logic, we can state that if 2 cm = 30 mi, then 4 cm = 60 mi (double the 2 cm will result in doubling the 30 cm), and 1 cm = 15 mi (if you divide the 2cm by 2, 30mi will also be divided by 2). Because of this, 5cm (4cm + 4cm + 1cm) on the map equals 75mi (which is 30mi + 30mi + 15mi).

Rational numbers include all integers and fractions. All negative integers and whole numbers make up the set of integers. Whole numbers comprise of all natural numbers and zero.

Every Rational number is not a whole number because A whole number is a component set of zero and all positive numbers such as 0, 1, 2, 3, 10, 15,… include only positive integers. It excludes negative integer, decimal, and fractional values .

Rational Number includes all the fractions, integers as well as decimal numbers.

Here set of whole number like 3, 4, 5 we can write this number as a fraction of 1 like 3/1, 4/1, 5/1… in ratio of two integers. Therefore every whole number is a rational number but every rational number is not a whole number.

Whole numbers are that starts from 0 to infinity. Whole numbers can be written in the form of 0/1, 1/1, 2/1, … Thus, every whole number is a rational number but every rational number is not a whole number.

The solution of the given equation by rounding off it to the nearest ten-thousandth is 7.8295.

What is a round-off of the digit?

In mathematics, a round-off is defined as an approximation of the given number to a fewer number of significant digits by taking into consideration some rules.

For eg: 13.58 ~ 13.6

Solving the given equation: log₇3x = 3

We are given a logarithmic expression: log₇3x = 3        —- 1

We know that log₇3 = log 3 / log 7 and log (ab) = log a + log b

Using in equation 1, we have,

log₇3x = 3

log 3x / log 7 = 3

(log 3 + log x) / log 7 = 3

log 3 + log x = 3 × log 7

log 3 + log x = 2.535

log x = 2.535 - 0.4771

log x = 2.0579

x = 7.8295

Hence, the solution of the given equation rounded off to the nearest ten-thousandth is 7.8295.
