A repeating decimal can be a rational number.

Rational

Rational and irrational numbers are 2 of the broadest categories within real numbers.

Writing the Number as a Fraction

Rational numbers are defined as numbers that can be written as simple fractions. Simple fractions have integers for the numerator and denominator. This means neither the numerator nor denominator is a fraction or decimal. The number above is 0.25 repeated. When 2 digits are repeated you can place that number over 99 to create an equivalent fraction.

Since this number can be written as a fraction, it must be a rational number.

Bar Notation

Additionally, repeated decimals are always rational. In the example above, the digits .25 are repeated. If you don't want to write it as a fraction, you can use bar notation. Bar notation helps to shorten repeated decimals and show that they are rational. In this notation, you place a bar over the digits that are repeated.

The work required to pump the oil out of the spout is 4 × 10⁶ Joules.

We have the information from the question:

A tank is is half full of oil that has a density of 900 kg/m3.

We have to find the work w required to pump the oil out of the spout.

By using Pythagoras theorem :

\(r^2+y^2=3^2\\\\r^2+y^2=9\\\\r =\sqrt{9-y^2}\)

Now, We have to find the volume of a tank :

V = \(\pi r^2\)Δy

V = \(\pi (\sqrt{9-y^2})^2\)Δy

V = \(\pi ({9-y^2})\)Δy

Mass = Density × Volume

m = \(\pi ({9-y^2})\)Δy × 900

m = 900 \(\pi ({9-y^2})\)Δy

Now, Find the force

Force = Mass × acceleration due to gravity

Force = 900 \(\pi ({9-y^2})\)Δy × 9.8

Force = 8820  \(\pi ({9-y^2})\)Δy

A distance of 4 - y is moved :

Work  = force × distance

Work =  8820  \(\pi ({9-y^2})\)Δy × 4 -y

Work = \(\int\limits^3_-_3 {8820\pi ({9-y^2})} (4-y)\)

Work =  4 × 10⁶ J

There are 66 ways to choose two vehicles from the dealer's inventory.

A combination is a grouping of items from a larger set in which the order of the items is irrelevant. In other words, it is a method of selecting a subset of items from a larger set without regard for their order of selection.

The formula C(n, k) = n! / (k! (n - k)!) can be used to calculate the number of combinations.

where n represents the total number of items in the set and k represents the number of items in the combination.

The exclamation mark (!) represents the factorial function, which is the sum of all positive integers up to a certain number.

The number of ways to select two vehicles from 8 cars and 4 trucks is 8 + 4 = 12 vehicles.

To find the number of combinations, we use the formula for combinations, which is:

C(n, k) = n! / (k! (n - k)!)

where n is the total number of vehicles and k is the number of vehicles we want to choose.

So, for n = 12 and k = 2,

we have:

So, putting the value in above formula:

We will get it as:

C(12, 2) = 12! / (2! (12 - 2)!) = (12 * 11) / (2 * 1) = 66

The conditional probability that the size of the family is less than 6 given that it is at least 3 is 1.

To find the conditional probability that the size of the family is less than 6 given that it is at least 3, we need to use the formula for conditional probability.

Let's denote A as the event that the size of the family is less than 6, and B as the event that the size of the family is at least 3.

The conditional probability of A given B, denoted as P(A|B), is calculated as follows:

P(A|B) = P(A and B) / P(B)

First, we need to find P(B), the probability that the size of the family is at least 3. Since the family is selected at random, we can assume that all possible family sizes have an equal chance of being selected.

Let's assume the total number of possible family sizes is n. The probability of selecting a family with at least 3 members is the sum of the probabilities of selecting a family with exactly 3 members, exactly 4 members, and exactly 5 members.

P(B) = P(3) + P(4) + P(5)

Next, we need to find P(A and B), the probability that the size of the family is both less than 6 and at least 3. Since any family size less than 6 is also at least 3, P(A and B) will be the same as P(B).

Finally, we can substitute the values into the formula for conditional probability:

P(A|B) = P(A and B) / P(B) = P(B) / P(B) = 1

Therefore, the conditional probability that the size of the family is less than 6 given that it is at least 3 is 1.

The band boosters had custom t-shirts made for homecoming and need to sell a certain number of shirts to cover their expenses. An equation, 10x = 25.90 + 8.15x, can be used to determine the number of shirts they need to sell to break even.

Let's break down the given information and formulate an equation to represent the situation.

The band boosters paid a setup fee of $25.90 and an additional cost of $8.15 per shirt to have the custom t-shirts made. They plan to sell each shirt for $10.

Let's represent the number of shirts they need to sell as 'x'. The cost to produce 'x' shirts would be the sum of the setup fee and the cost per shirt multiplied by the number of shirts:

Cost to produce 'x' shirts = Setup fee + (Cost per shirt × Number of shirts)

Using the given values, the equation becomes:

Cost to produce 'x' shirts = $25.90 + ($8.15 × x)

To break even, the revenue from selling the shirts should equal the cost to produce them. The revenue can be calculated by multiplying the selling price per shirt ($10) by the number of shirts sold:

Revenue from selling 'x' shirts = Selling price per shirt × Number of shirts sold

The equation representing the situation can be written as:

$10x = $25.90 + ($8.15 × x)

Simplifying the equation, we have:

10x = 25.90 + 8.15x

Now we have the equation that represents the situation.

The scientist should use 90 ounces of solution A and 90 ounces of solution B to obtain a 180-ounce mixture that is 55% salt.

Let's assume the scientist uses x ounces of solution A and (180 - x) ounces of solution B.

Since solution A is 40% salt, the amount of salt in solution A would be 0.40x ounces.

Similarly, since solution B is 90% salt, the amount of salt in solution B would be 0.90(180 - x) ounces.

To obtain a mixture that is 55% salt, the total amount of salt in the mixture should be 0.55(180) ounces.

Therefore, we can set up the equation:

0.40x + 0.90(180 - x) = 0.55(180).

Simplifying the equation, we get

0.40x + 162 - 0.90x = 99.

Subtracting 162 from both sides and combining like terms, we have -0.50x = -63.

Dividing both sides by -0.50 gives

x = 126.

Thus, the scientist should use 126 ounces of solution A (40% salt) and (180 - 126) = 54 ounces of solution B (90% salt) to obtain a 180-ounce mixture that is 55% salt.

The temperature in the bedroom varies by 4 degrees over the winter. It's crucial to keep in mind that these calculations are just one way to analyse the data and that other tools and techniques may be used to obtain a more thorough understanding of how temperature variations are measured.

We can use a variety of statistical tools, such as the calculation of central trend measures (like the mean, median, or mode) and dispersion measures (like the range, standard deviation, or variance coeficient), to analyse variations in the measurement of a room's temperature during the winter.

If we calculate the mean of the measurements, we get:

(2 + 1/2 + 9/2 + 3/2 + 7 + 5/2) / 6 = 30/6 = 5

As a result, the bedroom's average temperature in winter is five degrees.

We may also calculate the median, which is the value that falls in the middle of the measurements arranged from smallest to largest:

1/2, 3/2, 2, 5/2, 7, 9/2

The median is 4, therefore half of the measurements are lower or equal to 4 degrees, and the other half are higher or equal to 4 degrees.

In terms of the dispersion of the measurements, we may compute the range, which is the difference between the maximum and minimum value:

Rango = 9/2 - 1/2 = 4

As a result, the temperature in the bedroom varies by 4 degrees over the winter.

It's crucial to keep in mind that these calculations are just one way to analyse the data and that other tools and techniques may be used to obtain a more thorough understanding of how temperature variations are measured.

The parameterized equations for x and y are: x = 3 - 5t and y = -5t for the parameter.

From (3,0) to (-2,-5 ) can be parameterized. Vector form of the equation. The parameter equations for x and y involve linear interpolation between start and end points.

Let P be the start point (3,0) and Q be the end point (-2,-5). The vector form of the line segment equation can be written as:

r(t) = P + t(Q - P)

In this case P = (3,0) and Q = (-2,-5). Substituting these values ​​gives:

r(t) = (3,0) + t((-2,-5) - (3,0))

Further simplification:

r(t) = (3,0) + t(-5,-5)

= (3,0) + (-5t,-5t)

= (3 - 5t, -5t)

So the parameterized equations for x and y are

x = 3 - 5t

y = -5t

These equations run from (3,0) to (-2,-5) such that the line segment is at (3,0) at t=0 and (-2,-5) at t=1. Parameterize the line segment. By varying the value of t from 0 to 1, you can trace a line segment between two points.

Answer:

\( x = 20 \)

Step-by-step explanation:

\( \frac{3}{5}x - \frac{1}{4}x = 7 \)

The LCD is 20, so multiply both sides of the equation by 20.

\( 20(\frac{3}{5}x - \frac{1}{4}x) = 20 \times 7 \)

\( 4 \times 3x - 5 \times x = 140 \)

\( 12x - 5x = 140 \)

\( 7x = 140 \)

The average velocity from t = 2s to t = 4s would be - 48 ft/s.

In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that an object is thrown upward with initial velocity of 48 feet per second from a high of 120 feet. The height of the object t seconds after it is thrown is given by h(t) = - 16t² + 48t + 120.

Average rate of change of velocity with time is called average velocity. Mathematically -

v{avg.} = Δx/Δt                                                         .... Eq { 1 }

Δx = x(4) - x(2)

Δx = - 16(4)² + 48(4) + 120 - {- 16(2)² + 48(2) + 120}

Δx = - 96

Δt = 4 - 2 = 2

So -

v{avg.} = Δx/Δt = -96/2 = - 48 ft/s

Therefore, the average velocity from t = 2s to t = 4s would be - 48 ft/s.

1) El triángulo tiene un perímetro cuyo valor es 19 cm y un área de 14,92 cm²

2) La circunferencia tiene un perímetro cuyo valor es 14,14 cm y un área de 15,90 cm²

Step-by-step explanation:

El perímetro es una medida de la distancia alrededor de una figura y el área da una idea de qué tanta superficie cubre dicha figura.

Entonces, el perímetro es la medida obtenida como resultado de la suma de los lados de una figura geométrica plana. Es decir, el perímetro es lo que mide el contorno de la figura.

El área de un triángulo es igual a base por altura dividido por 2.

Siendo r el radio de la circunferencia, el perímetro será calculado como:

P=2*π*r

y el área será:

A=π*r²

1) En este caso, el perímetro es calculado como:

P= 6 cm + 8 cm + 5 cm= 19 cm

Y el área del triángulo es calculada como:

\(A=\frac{base*altura}{2} =\frac{8 cm*3.73 cm}{2}\)

A= 14,92 cm²

El triángulo tiene un perímetro cuyo valor es 19 cm y un área de 14,92 cm²

2) Siendo el diámetro un segmento de recta que va desde un punto de la circunferencia a otro y pasa por el centro del círculo y l radio la distancia desde el centro del círculo hasta un punto de la circunferencia, entonces, el radio es la mitad del diámetro.

Siendo el diámetro de la circunferencia 4,5 cm, entonces el radio r tiene un valor de 2,25 cm.

Entonces el perímetro será calculado como:

P=2*π*2,25 cm

P= 14,14 cm

y el área será:

A=π*(2,25 cm)²

A= 15,90 cm²

La circunferencia tiene un perímetro cuyo valor es 14,14 cm y un área de 15,90 cm²
