Answer:

1/6

Step-by-step explanation:

You can change 1.5 into a fraction.
1.5 = 3/2
Now you can multiply the two fractions easily: the two numerator values multiply and the two denominator values multiply.
1/9 * 3/2 = 3/18.

You can further simply this fraction by noting that 3 divides into 18.

So the answer is 1/6.

On solving the provided question, we can say that value of the equation , h = [tex]\frac{M}{Zg} + f[/tex]

Two assertions in a mathematical equation are joined by the equal sign (=), which stands for equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places a space between the variables 3x + 5 and 14. The connection between the two sentences on either side of a letter is explained by a mathematical formula. Typically, there is only one variable, which also serves as the symbol. In this case, 2x4=2.

Answer:

it will take approximately 3 and 1/3 days for 12 chickens to lay 100 eggs.

Answer:

  P ∈ {3, 5, 6, 8}

Step-by-step explanation:

You want the possible perimeter values such that there can only be one triangle with that perimeter and integer side lengths.

The requirement that the triangle satisfies the triangle inequality means the longest side must be shorter than P/2.

The smallest triangle with integer side lengths is the {1, 1, 1} equilateral triangle.

  P=3, {1, 1, 1}

For P=4, the longest side can be neither 1 nor 2, so P=4 is not an option.

For P=5, the longest side can be 2, requiring the other sides to be 2 and 1:

  P = 5, {2, 2, 1}

For P=6, the longest side must be less than 3, so all sides must be 2.

  P = 6, {2, 2, 2}

For P=7, two triangles are possible: {3, 3, 1} and {3, 2, 2}.

For P = 8, the longest side must be less than 4, so will be 3. The other two sides must be 3 and 2.

  P = 8, {3, 3, 2}

For all values of P above 8, there are at least two possible triangles.

Possible values of P are 3, 5, 6, 8.

For the values 44. 4, 43. 8, 45. 6, 45. 9, 44. 1, 45. 6, 44. 0, 44. 9, 45. 8, the mean of the data set is 49.52. The Mean Absolute Deviation (MAD) of the data set is 4.83.

To find the mean of the given data set, we add up all the values and divide by the number of values:

Mean = (44.4 + 43.8 + 45.6 + 45.9 + 44.1 + 45.6 + 44.0 + 44.9 + 45.8) / 9 = 445.7 / 9 = 49.52

So, the mean of the data set is 49.52.

To find the Mean Absolute Deviation (MAD), we first find the absolute difference between each value and the mean, and then find the mean of these absolute differences:

Absolute Difference = |44.4 - 49.52|, |43.8 - 49.52|, ..., |45.8 - 49.52|

MAD = (Absolute Difference1 + Absolute Difference2 + ... + Absolute Difference9) / 9

Calculating the MAD gives:

MAD = (5.12 + 5.72 + 3.92 + 3.62 + 5.42 + 3.92 + 5.52 + 4.62 + 5.32) / 9 = 43.5 / 9 = 4.83

So, the Mean Absolute Deviation (MAD) of the data set is 4.83.

The solution of Representing an arithmetic sequence as a linear function involves finding the equation of a line in the form of y = mx + b.

Here m represents the common difference and b represents the initial term of the sequence. To do this, choose any two terms from the arithmetic sequence and use them to solve for the slope (m) and y-intercept (b). For example, if the two terms are a_n and a_n+k, where k is a constant, you can use the formula: m = (a_n+k - a_n) / k.

Once you have the slope, use one of the two terms and the slope to solve for the y-intercept using the equation y = mx + b. This will give you the equation for the line representing the arithmetic sequence. By using this method, you can practice representing arithmetic sequences as linear functions and find the equation of a line that represents any given arithmetic sequence.

The measures angles are 70° and 52°  

The triangle in which the ratio of corresponding is equal and has an equal measure of angles is known as Similar triangle.

If ABC and XYZ are two similar triangles, the corresponding angles must be equal

=> ∠A = ∠X, ∠ B = ∠Y, ∠C = ∠Z

Here we have

ΔDEF and ΔJKL are similar triangles

As we know angles of similar triangles are equal

=> ∠D = ∠J = (9x - 20)°

=> ∠E = ∠K = 52°

=> ∠F = ∠L = (7x - 12)°      

As we know the sum of angles in triangles = 180°  

=> ∠D + ∠E + ∠F = 180°

=> 9x - 20° + 52° + 7x - 12° = 180°  

=> 16x + 20° = 180°  

=> 16x = 160°  

=> x = 160°/16

=> x = 10°    

At x = 10° measures of angles are

=> (9x - 20)° = 9(10) - 20° = 70°

=> (7x - 12)° = 7(10) - 12° = 58°  

Therefore,

The measures angles are 70° and 52°

A graph that passes the horizontal line test represents a function. This is because if a horizontal line can only intersect the graph at one point, it means that each input value (x) has a unique output value (y), which is the definition of a function. This is true.

I agree with Lionel, the graph should show a continuous line because age increases gradually like time. Also, age is usually not a discrete variable, it's a continuous variable that can have fractional values, so a line graph is more appropriate to represent the relationship between age and gas mileage.

Let's take f(x) = 3x - 7 and g(x) = -2x + 5 as two linear functions.

f(x) - (-g(x)) = 3x - 7 - (-2x + 5) = 3x - 7 + 2x - 5 = 5x - 12

f(x) + g(x) = 3x - 7 + (-2x + 5) = x - 2

So f(x) - (-g(x)) is not equivalent to f(x) + g(x). This result would not apply to every function, as the properties of addition and subtraction of functions depend on the specific functions being used.

Precession and nutation are two distinct motions of a spinning top or gyroscope. Precession is a slow, uniform motion that results from the gravitational force acting on a spinning top or gyroscope.

It is a slow, uniform motion in which the spinning object's axis of rotation moves in a cone-like motion.

Nutation is a fast, non-uniform motion that is caused by the torque of a nearby force. It is a rapid, irregular motion that causes the spinning object's axis of rotation to wobble back and forth.

Precession is a regular, predictable motion, whereas nutation is an unpredictable, irregular motion. Precession is typically used to describe the motion of a satellite or planet in its orbit, while nutation is used to describe the motion of a spinning top or gyroscope.

Precession and nutation are two different types of rotational movements in astronomy.

Precession refers to the slow, conical movement of an object's rotational axis, which changes the orientation of the object over time. In the case of Earth, precession causes the direction of the North Pole to change over time.

Nutation, on the other hand, is a rapid, irregular movement of an object's rotational axis. It is caused by the combined gravitational forces of the Sun, Moon, and other celestial bodies on the Earth. Unlike precession, nutation occurs in small, cyclical changes in the orientation of the rotational axis, causing the axis to move slightly back and forth.

In summary, precession is a slow, systematic change in the orientation of an object's rotational axis, while nutation is a rapid, irregular movement of the axis caused by external forces.

Answer:

1.25a

Step-by-step explanation:

Original value = a

An increase of 25% can be found by a x 25/100 = 0.25a

The resulting increased value = Original value + Increase in value

= a + 0.25a

= 1.25a

Sometimes it is a more direct approach to use the final value as original value(1 + increase%/100) in which case it would be a(1+25/100) = a(1 + 0.25) = a(1.25) = 1.25a

Find the number pattern (check image)

The shape consisting of 28 squares will have 812 sticks.

From the given data, we can see that the number of squares is increasing by consecutive odd numbers, starting from 1:

1, 3, 6, 10, 15, ...

Also, the number of sticks is increasing by consecutive even numbers, starting from 4:

4, 10, 18, 28, 40, ...

This suggests that the number of sticks required to make a pattern of n squares can be found using the formula:

sticks = 2n + (n-2) + (n-4) + ... + 4

This formula represents the sum of the first n even numbers, which can be simplified to:

sticks = n(n+1)

Using this formula, find the number of sticks required to make a pattern of 28 squares:

sticks = 28(28+1) = 28(29) = 812

To determine whether VY is parallel to ZW, we need to see if the ratio of their corresponding sides is equal.

The ratio of corresponding sides of two parallel lines is constant, so we can set up an equation to compare the ratios:
