Find how long it takes a person to drive 260 miles on a highway if she merges onto a highway at 7 p.m. and drives nonstop with her cruise control set on 80 mph.

Answers

Answer 1

When time is also known, distance—the measurement of how far something has travelled in a straight line—can be used to determine speed.

Step-by-step explanation:Speed can be calculated using distance—the amount of distance something has travelled in a straight line—when time is also known.

Distance, D = 260 miles

Velocity, V = 80 miles/hour

Time taken, t = distance/velocity

= D/V

= 260/80

= 3.25 hours

It takes 3 hours 25 minutes.

Question 3 4 pts Solve the equation for the variable. Show your work and be sure to not forget to show all of your steps. -3(3 + 6b) = 36 - 3b​

Answers

Answer:

[tex]\huge\boxed{\sf b = -3}[/tex]

Step-by-step explanation:

Given equation:

-3(3 + 6b) = 36 - 3b

Distribute

-9 - 18b = 36 - 3b

Add 3b to both sides

-18b + 3b - 9 = 36

-15b - 9 = 36

Add 9 to both sides

-15b = 36 + 9

-15b = 45

Divide -15 to both sides

b = 45/(-15)

b = -3

[tex]\rule[225]{225}{2}[/tex]

Answer:

The value of b is -3.

Step-by-step explanation:

The equation is,

→ -3(3 + 6b) = 36 - 3b

Now the value of b will be,

→ -3(3 + 6b) = 36 - 3b

→ -3(3) - 3(6b) = 36 - 3b

→ -9 - 18b = 36 - 3b

→ -18b + 3b = 36 + 9

→ -15b = 45

→ b = -(45/15)

→ [ b = -3 ]

Hence, the value of b is -3.

Jasper claims that there exists a regular polygon for which the measure of each interior angle of the polygon is four times the minimum angle of rotation about its center that carries the polygon onto itself.

For the case where Jasper's claim is true, complete the table by entering the correct information for such a regular polygon.

Answers

It is not possible for the measure of each interior angle of a regular polygon to be four times the minimum angle of rotation about its center that carries the polygon onto itself.

What is the interior angle?

The inner of the two angles formed where two sides of a polygon come together. any of the four angles formed in the area between a pair of parallel lines when a third line cuts them.

Jasper's claim is not true. The minimum angle of rotation about the center of a regular polygon that carries the polygon onto itself is called the polygon's "order of rotational symmetry." This angle is always less than or equal to 180 degrees, and it is equal to 360 degrees divided by the number of sides in the polygon.

For example, a regular hexagon has an order of rotational symmetry of 60 degrees (360 degrees / 6 sides), and a regular octagon has an order of rotational symmetry of 45 degrees (360 degrees / 8 sides).

Therefore, if the measure of each interior angle of a regular polygon is four times the minimum angle of rotation about its center that carries the polygon onto itself, then the measure of each interior angle would have to be at least 720 degrees. However, the sum of the interior angles of a regular polygon with n sides is 180(n-2) degrees, which is always less than 720 degrees for any value of n greater than 2.

Therefore, it is not possible for the measure of each interior angle of a regular polygon to be four times the minimum angle of rotation about its center that carries the polygon onto itself.

Use the Line Tool to graph the proportional relationship that gives the number of liters of water the facet supplies, y, after x minutes.

Answers

The graph of the proportional relationship is added as an attachment

How to determine the graph of the scenario

From the question, we have the following parameters that can be used in our computation:

Time = 3 minutes

Supply of water = 12 litres

Using the above parameters, we have the following ordered pairs

(0, 0) and (3, 12)

Rewrite the above points properly

So, we have the following ordered pairs

(x, y) = (0, 0) and (3, 12)

The gradient of the line is then calculated using the following slope equation

gradient = (y₂ - y₁)/(x₂ - x₁)

Where

(x, y) = (0, 0) and (3, 12)

Substitute the known values in the above equation

So, we have the following equation

gradient  = (12 - 0)/(4 - 0)

Evaluate

gradient  = 3

The equation of the line is then calculated as

y = gradient * x

Substitute the known values in the above equation

So, we have the following equation

y = 3 * x

Evaluate the products

y= 3x

Hence, the line equation is y= 3x

Answers

By solving equations, we know that there were 2187 adult partons.

What are equations?

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.

A function is an equation with a single solution for y for each value of x.

Each input of a particular type receives exactly one output when using a function.

Instead of y, a function is frequently named f(x) or g(x).

When x equals 2, we should determine our function's value because f(2) says to do so.

So, the number of adult patrons was:

Let, a be an adult and c be children.

Total tickets:

a + c = 5200

c = (5200-a)

Total amount:

7.50a + 4.50c = 29961

Replace c in the first equation with (5200-a).

7.5a + 4.5(5200-a) = 29961

7.5a + 23400 - 4.5a = 29961

7.5a - 4.5a = 29961 - 23400

3a = 6561

a = 6561/3

a = 2187

Therefore, by solving equations, we know that there were 2187 adult partons.

If these fractions are simplified to produce comparable fractions, such as e/f, they are then equal to one another.

For instance, if we simplify 5/15, the resulting fraction is the same as 1/3, hence that is the equivalent fraction of 1/3.

The fractions with distinct numerators and denominators but the same value are said to be equivalent fractions. For instance, since 2/4 and 3/6 both equal the 12, they are identical fractions. An element of a whole is a fraction. The same amount of the whole is represented by equivalent fractions.

2x + 3 (x - 2) = 6 (x - 1) - x → All real numbers

2x + 3 (x - 2) = 6 (x - 1) + x → x = 0

2x + 3 (x - 1) = 6 (x - 1) - x → No solution.

What is equation?

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.

Given:

The equation is, 2x + 3 (x - 2) = 6 (x + 1) + x, 2x + 3 (x - 2) = 6 (x - 1) - x, 2x + 3 (x - 2) = 6 (x - 1) + x, and 2x + 3 (x - 1) = 6 (x - 1) - x

Solve the above equations as shown below,

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

2x + 3x - 6 = 6x + 6 + x

5x - 6 = 7x + 6

7x - 5x = -6 - 6

x = -6

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

2x + 3x - 6 = 6x - 6 - x

5x  - 6 = 5x - 6

Infinity solutions,

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

2x + 3x - 6 = 6x - 6 + x

5x - 6 = 7x - 6

x = 0

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

this is the same principle in every posted question.

I hope you understand this now.

if not please let me know what is still a "riddle" to you, so that I can explain it better.

remember, the inverse function of y = e^x is x = ln(y).

and the inverse function of y = ln(x) is x = e^y.

we want to find the value of x, where f(x) = 28.

28 = 0.48ln(x + 2) + 27

1 = 0.48ln(x + 2)

1/0.48 = ln(x + 2)

e^(1/0.48) = x + 2

x = e^(1/0.48) + 2 = 10.03119499... miles ≈ 10 miles

the pressure of 28 inches of mercury occurs about 10 miles from the eye of the hurricane.

What is Mean?

A group of two or more numbers is simply averaged mathematically to get the term "mean." There are several ways to calculate the mean for a given collection of numbers, including as the arithmetic mean approach, which utilises the sum of the series' values, and the geometric mean method, which uses the average of a group of products. However, the majority of the time, the results from all of the main approaches to calculating a simple average are roughly the same.

There are two different types of means that can be calculated: the arithmetic mean and the geometric mean.

The arithmetic mean is calculated by adding all of the numbers in a set and dividing by the total number of numbers in the set.

Mean is the ratio of sum of observations to the total number of observation.
