Answer: 40 degrees

Step-by-step explanation:

m/CBA = m/CED

16 + 6x = 48 - 2x; add 2x on both sides and subtract 16 on both

8x = 32; divide 8 on both sides to isolate the x

x = 4

m/CBA = 16+6(4) = 40

We need to know how many gallons of gas $23.36 will buy, so we divide the amount by the cost per gallon: $23.36 ÷ $3.25 per gallon = 7.20 gallons.

Once we know how many gallons of gas we are buying, we can then find out how long it will take to pump that amount of gas. To do that, we multiply the number of gallons by the time per gallon: 7.20 gallons × 21 seconds/gallon = 151.2 seconds.

So, the answer to the question is 151.2 seconds, which is the total time it will take to pump $23.36 worth of gas at $3.25 per gallon and 21 seconds per gallon.

Step 1: Calculate the number of laps the cars have completed. To calculate the number of laps the cars have completed, divide the total time (150 seconds) by the time it takes car A to complete one lap (30 seconds), which gives us a total of 5 laps.

Step 2: Calculate the possible times for car B. To calculate the possible times for car B, we need to find out how many times car B must complete a lap in order to keep up with car A. Since car A takes 30 seconds to complete one lap and the cars have completed 5 laps in 150 seconds, car B must take the same amount of time as car A, i.e. 30 seconds, in order to keep up with car A. Therefore, the possible times for car B are 30, 60, 90, and 120 seconds.

Therefore, the four possible times that car B could take to complete one lap are 30, 60, 90, and 120 seconds.

The letters in the word MIAMI are rearranged at random so that every possible anagram is equally likely. The probability that it still spells MIAMI is 1/5.

Let us count the total number of ways MIAMI can be arranged regardless of condition.

There are 2 M’s 2 I’s 1 A in word.

Total ways of arrangement will be = 5!/2!2!

​Total ways of arrangement will be = (5 × 4 × 3 × 2!)/2! × 2 × 1

Total ways of arrangement will be = 5 × 2 × 3

Total ways of arrangement will be = 30 ways

Now, ways in which all similar words are together, thus we have to consider 2M's as one unit, similarly 2 I's as a unit, so number of ways will be 3!.

The slope of a straight line that is parallel to the vertical axis is zero.

A slope of zero indicates that the line is flat and has no incline or decline. In a two-variable diagram, this means that there is no relationship between the two variables, as a change in one variable does not affect the value of the other. A line with a slope of zero is a horizontal line, and its equation is of the form y = b, where b is a constant value.

In contrast, a line with an infinite slope (or vertical line) would indicate a perfect correlation between the two variables, such that a change in one variable would result in an infinite change in the other. A line with a finite positive or negative slope would indicate a direct or inverse relationship between the two variables, respectively.

Step-by-step explanation:

The midpoint of AC is (2,0), and the midpoint of BC is (0,2.5). The third vertex of triangle DEC is E, the midpoint of AB, which can be found using the midpoint formula:

E = ( (A_x + B_x) / 2, (A_y + B_y) / 2 )

= ( (0 + 2) / 2, (0 + 5) / 2 )

= (1, 2.5)

So the vertices of triangle DEC are (0, 2.5), (2, 0), and (1, 2.5). The area of triangle DEC is half the area of triangle ABC, which is (4 * 5) / 2 = 10. So the area of triangle DEC is 10 / 2 = 5.

The ratio of baking powder to flour is 1/192 teaspoon of baking powder for every teaspoon of flour.

The amount of baking powder per unit of flour is the unit rate for baking powder and flour. The amount of flour in this situation equals 1 2/3 cups. We must change the baking powder measurement to the same unit as the flour measurement in order to calculate the unit rate.

For every 1 2/3 cups of flour, 1/4 teaspoon of baking powder should be used as follows:

1/4 teaspoon / (1 2/3 cups)

By changing the numerator and denominator of the fraction on the right side to a standard unit, such as teaspoons, we may make it simpler. 1 2/3 cups equal 48 teaspoons, so:

1/4 teaspoon / (1 2/3 cups) = 1/4 teaspoon / (48 teaspoons)

The ratio of baking powder to teaspoons is as follows:

1/4 teaspoon / (48 teaspoons) = 1/192 teaspoon per teaspoon

Answer:

Step-by-step explanation:

Inverse variation functions have the form y = k / x, where k is a constant.

When k > 0, the graph of the inverse variation function is a hyperbola that opens upwards or downwards, depending on the sign of k. When k > 0, the hyperbola opens upwards and the two branches of the hyperbola move away from the x-axis as x increases. This means that as x increases, the value of y decreases. When x approaches 0 from the right, y approaches positive infinity, and when x approaches 0 from the left, y approaches negative infinity.

On the other hand, when k < 0, the graph of the inverse variation function is a hyperbola that opens upwards or downwards, depending on the sign of k. When k < 0, the hyperbola opens downwards and the two branches of the hyperbola move toward the x-axis as x increases. This means that as x increases, the value of y increases. When x approaches 0 from the right or left, y approaches negative infinity.

In both cases, the inverse variation function is undefined for x = 0, as division by zero is undefined.

The answer to the expression 2b x b is simply 2b^2. Exponentiation is a mathematical operation that raises a number to a power, and in this case, b is raised to the power of 2.

Alternatively, if exponentiation is not allowed, the answer to the expression is simply 2b * b, which can be simplified to 2b^2 as well.

So, the answer to the expression 2b x b is 2b^2, regardless of whether or not exponentiation is used.

The expression 2b x b represents the product of two scalars, 2 and b, multiplied by a scalar b.

The forecast for this year (F(6)) is 18,625. Therefore, the correct answer is 18,625.

Exponential smoothing is a time series forecasting method that uses a weighted average of past observations to make predictions. In this case, the weight assigned to each observation is determined by a smoothing parameter, alpha, which is a value between 0 and 1.

The formula for exponential smoothing with alpha = 0.5 is given by:

F(t) = alpha * Y(t) + (1 - alpha) * F(t-1)

where F(t) is the forecast for time t, Y(t) is the actual observation at time t, and F(t-1) is the forecast for the previous time period.

Starting with the forecast for two years ago, we can use this formula to make a forecast for each year until this academic year.

F(2) = 0.5 * 20,000 + (1 - 0.5) * 16,000 = 18,000

F(3) = 0.5 * 18,000 + (1 - 0.5) * 18,000 = 18,000

F(4) = 0.5 * 16,000 + (1 - 0.5) * 18,000 = 17,000

F(5) = 0.5 * 15,000 + (1 - 0.5) * 17,000 = 16,250

F(6) = 0.5 * 21,000 + (1 - 0.5) * 16,250 = 18,625

The label 24x - 48 applies to the expression because it is the same as itself. The value obtained by multiplying 24 by x and then taking 48 out is represented by this expression.

The label "36x + 12" applies to the expression because it is the same as itself. The value generated by multiplying 36 by x and then adding 12 is represented by this expression.

Since the formulations in both situations have distinct coefficients for x and various constant terms, they are not comparable to one another. Since both expressions are equal to one another, the term "neither" does not apply to them.

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

Given, At a height of n meters above sea level, the atmospheric pressure is Pn millibars. At a height of (n + 1000) meters above sea level, the atmospheric pressure is P(n + 1000) millibars.

where,

P(n + 1000) = 0.88Pn

at n = 0

P(1000) = 0.88 P(n = 0)

Since,

P(n = 0) is 1013 milibar

thus,

P(1000) = 0.88 * 1013

At n = 1000

P(1000 + 1000) = 0.88 P(n = 1000)

P( 2000) = 0.88 * 0.88 *1013

at n = 2000

P(2000 + 1000) = 0.88 P(n = 2000)

P( 3000) = 0.88 *0.88* 0.88 *1013

Thus,

P(3000) = 690.33

(-6,-5), (-2,3), (2,-5), (6,3) are the ordered pairs given on the graph.

In mathematics, a transformation is a process that changes the position, size, or orientation of a geometric shape or figure. The term is used in various branches of mathematics, including geometry, algebra, and calculus.

In geometry, transformations include translations, rotations, reflections, and dilations. A translation involves moving a shape a certain distance in a certain direction, while a rotation involves rotating a shape around a fixed point. A reflection involves flipping a shape over a line, and a dilation involves stretching or shrinking a shape by a given scale factor.

In algebra, transformations can involve changing the form of an equation, such as solving for a variable, transforming an equation into a different coordinate system, or solving a system of equations.

In calculus, transformations can involve changing the form of a function, such as finding its derivative or integral, or transforming a function from one coordinate system to another.

To find the ordered pairs that are on the transformations of the function, we can apply the transformations to the original point (-2, -1) to obtain the points on each transformation.

y = f(x-4) - 4: If we apply the x-4 transformation to the x-coordinate of the original point, we get -2-4 = -6. So, the point is (-6, f(-6) - 4).

y = f(x-4) + 4: The x-coordinate of the point is -6, so the point is (-6, f(-6) + 4).

y = f(x+4) - 4: If we apply the x+4 transformation to the x-coordinate of the original point, we get -2+4 = 2. So, the point is (2, f(2) - 4).

y = f(x+4) + 4: The x-coordinate of the point is 2, so the point is (2, f(2) + 4).

So, the ordered pairs that must be on each of the transformations of f(x) are:

y = f(x-4) - 4: (-6, f(-6) - 4)

y = f(x-4) + 4: (-6, f(-6) + 4)

y = f(x+4) - 4: (2, f(2) - 4)

y = f(x+4) + 4: (2, f(2) + 4)
