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.

Answer:

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

Step-by-step explanation:

-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)

[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.

2/6 is the equivalent fraction for the fraction represented on the given number line. So, B is the correct option

What is an equivalent fraction ?

According to equivalent fractions, two or more fractions are considered to be equal if, following simplification, both provide the same fraction. Let's imagine that a/b and c/d are two fractions. 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.

as 2/6 can further reduced to 1/3 which is represented on to the number line  as 1/3 which is equal to 2/6

Answer:

  y = -4/9x

Step-by-step explanation:

You want the equation of the line through (0, 0) and (9, -4).

A line through the point (0, 0) represents a proportion. The slope of the line is the constant of proportionality, the ratio of y to x.

  k = y/x = -4/9

The equation of the line is ...

  y = kx

  y = -4/9x

You will always get one triangle. This is because of the Triangle Angle Sum Theorem, which states that the sum of the measures of the angles of a triangle is always 180°.

A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.

The inner angles of every triangle sum up to 180°, 180°, 180°, 180°. Angles in a triangle are the total (sum) of the angles at each of its three vertices.

Over the course of many​ games, one would expect the mean number of hits per game to be the mean of the random variable.

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.

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

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.

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

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.
