Answer:

22.31 minutes

Step-by-step explanation:

First simplify the numbers to decimals to make it easy : 2 1/3 = 2.30( estimated) ,  11 2/3 = 11.67 ( estimated ), and 4 2/5 = 4.4

The we divide how many miles by the total amount of minutes to get 5.07( estimated )

We then multiply it by 4.4 to get 22.308 to be exact.

So it will take him 22.31 minutes

Answer: If two lines are parallel, it means that they have the same slope. Therefore, to find the value of x in this problem, you need to find the slope of line m and line n, and then set them equal to each other.

The slope of a line can be found using the formula:

slope = (y2 - y1)/(x2 - x1)

In this case, you are given the equation of line m in the form "x + 1", and the equation of line n in the form "7x - 5". To find the slope of each line, you can rewrite these equations in the form y = mx + b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis).

For line m, we have:

y = x + 1

The slope of this line is m = 1.

For line n, we have:

y = 7x - 5

The slope of this line is m = 7.

Since line m and line n are parallel, their slopes must be equal. Therefore, we can set these slopes equal to each other and solve for x:

1 = 7

This equation has no solution, which means that there is no value of x that will make these two lines parallel. Therefore, the answer is that there is no solution.

By using the concept of function, it can be seen that the given graph represents a function.

What is a function?

A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.

There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.

Here the values on the  x axis represents the domain and the values on the y axis represents the Range.

From the graph it can be seen that

Every point of the domain maps to unique point on the range.

So this is a function

Answer:

x = 2, y = 3

Step-by-step explanation:

Solve the following system:

{-2 y + 3 x = 0 | (equation 1)

{-2 y + x = -4 | (equation 2)

Subtract 1/3 × (equation 1) from equation 2:

The measure of arc PD is 56.

What is a measure of arc?

The central angle that creates the intercepted arc's central angle, or the arc measure, is expressed in degrees. Arc length can be estimated as a percentage of the circle's circumference by multiplying the circle's diameter by the arc length, divided by 360.

Here, we have

Given: DR = 4x +4

PR = 50°

The sum of the measure of arc PR + DR = 180°

50° +  4x +4 = 180°

x = 4

Now we can find the measure of the arc of PD. we put the value of x in 12x+ 8 and we get

12(4) + 8 = 56

Hence, the measure of arc PD is 56.

Given that,

We have to find the distance between the points (3,5) and a line with the equation 5x-3y+10=0.

We know that,

We have a formula that is

Let (x₁, y₁) be the point and ax + by + c = 0 be the line.

Then the distance between a point and a line will be

d=|ax₁+by₁+c|/√(a²+b²)

Here,

Augustus used a total of 12 gallons + 1.8 gallons = 12+1.8=13.8 gallons of chocolate syrup in the three mixtures.

What is a percentage?

Percentages are essentially fractions where the denominator is 100. To show that a number is a percent, we use the percent symbol (%) besides the number. For example, if you got 75 questions right out of 100 on a test (75/100), you would have scored 75%.

Since Augustus used 10% chocolate syrup and 90% milk for the first mixture and 30% chocolate syrup and 70% milk for the second mixture, the total percentage of chocolate syrup he used in the first two mixtures is 10% + 30% = 40%.

Since Augustus made a total of 30 gallons of chocolate milk, he used 30 gallons * 40% =3040.01=12 gallons of chocolate syrup in the first two mixtures.

For the final mixture, Augustus used 15% chocolate syrup and 85% milk. The total percentage of chocolate syrup he used for the final mixture is 15%.

Since Augustus used a total of 12 gallons of chocolate syrup in the first two mixtures, he used an additional 12 gallons * 15% = 1215.01=11.8 gallons of chocolate syrup for the final mixture.

Hence, Augustus used a total of 12 gallons + 1.8 gallons = 12+1.8=13.8 gallons of chocolate syrup in the three mixtures.

On solving the provided question, we got that - y = 4, when x=2 and the hypotenuse of the resulting right triangle is 5.

[tex]AC^2 = AB^2 + BC^2[/tex] is the formula for the Pythagorean theorem, where AB is the perpendicular, BC is the base, and AC is the hypotenuse. All triangles with 90° angles are governed by the Pythagorean equation.

The hypotenuse formula can be used to define the relationship between the sides of a right triangle, making it a specific kind -

[tex]c^2 = a^2 + b^2\\or\\c^2 = x^2 + y^2[/tex]

where,

The triangle's hypotenuse, or c, is the side that faces away from the 90-degree angle.

while the sides closest to the 90° angle are denoted by a and b.

Given that the hypotenuse is 5 = c and one of the sides has a measure of 2 = x in the issue statement, we can calculate for y as follows:

[tex]y^2 = c^2 - x^2\\y^2 = 5^2 - 2^2\\y^2 = 21\\y = 4.58[/tex]

The power of three halves is equal to 3.

What is power?
Power is the ability to influence or control the behaviour of others, and to make decisions that affect the outcome of any given situation. It is a form of force that can be both positive and negative, and can be used in various ways. Power can come from a variety of sources, such as money, status, knowledge, physical strength, and social standing. It is a form of authority that can be used to motivate and inspire others, or to manipulate and coerce them. Power is an important part of many social and political systems, and is essential for effective leadership. It is an essential tool for achieving desired outcomes and can be used for good or for ill. Ultimately, power is a form of influence, and its use depends on the individual wielding it.

In general, if a is a positive real number and n is a positive integer, then a^(n/2) is equal to the square root of a^n. This can be written as:
a^(n/2) = sqrt(a^n) = a^(1/2) * a^(1/2)
