The value for $\frac{0.\overline{72}}{0.\overline{27}}$ as a common fraction in lowest terms is 2.666

To convert repeating decimals to fractions, we can use the following method:

Let's call the repeating decimal 0.72... = x, and the repeating decimal 0.27... = y.

Then 10x = 7.2... and 10y = 2.7...

Subtracting the original expressions from the above:

10x - x = 7.2... - 0.72...

=> 9x = 7

=> x = 7/9

And similarly,

10y - y = 2.7... - 0.27...

=> 9y = 2

=> y = 2/9

Therefore,

0.72... / 0.27... = x / y = (7/9) / (2/9) = 7/2 = 3.5

A repeating decimal is a decimal that has a repeating pattern of digits after the decimal point. To convert a repeating decimal to a fraction, we need to identify the repeating pattern and convert it to a fraction. This is done by multiplying both the numerator and denominator by a power of 10 that makes the repeating part an integer.

Then, the resulting fraction can be simplified to its lowest terms. In this case, the repeating decimals 0.72... and 0.27... can be converted to the fractions 7/9 and 2/9 respectively, and dividing the two results in a fraction of 7/2 can be simplified to 3.5.

The maximum profit Katie can earn is $85.

To find this, we need to use the vertex formula, which gives us the x-coordinate of the vertex of the parabola representing the profit function.

The formula is x = -b/2a, where a is the coefficient of the x-squared term (-1 in this case) and b is the coefficient of the x term (14 in this case). So, x = -14/(2*(-1)) = 7. Plugging this value into the profit function gives us P(7) = -7² + 14(7) + 57 = 85.

The profit function given is a quadratic function, which has a parabolic graph. The vertex of the parabola represents the maximum or minimum point of the function, depending on whether the leading coefficient is negative or positive. In this case, the leading coefficient is negative, so the vertex represents the maximum profit.

To find the x-coordinate of the vertex, we use the formula x = -b/2a, which gives us the value of x that makes the profit function equal to its maximum value. Once we have this value, we plug it back into the profit function to find the corresponding maximum profit. In this case, the maximum profit is $85.

Answer:

C 3/2

Step-by-step explanation:

Since triangle PRQ is the original and is getting bigger proportionally (can tell by side lengths) you can eliminate options A and B since you have to multiply by a number/fraction greater than one since it's getting bigger. Then pick a side corresponding to another side of the other triangle. For example, the side length of PQ is 8. Side length P'Q' is 12. You will need to consider how you get from that 8 since it's the original to the 12. To do that you will need to multiply by 1.5 to get to 12. this is what it means by dilation. Since 3/2=1.5 that would be your answer.

a) To represent Eduardo's age, we can write - Eduardo's age = X - 4

b) To represent the number of butterflies Eduardo has, we can write B = 2x + 12

6-67)

a) When x = 0: 3x-2 < 4x+4

b) When x = -6: 3x-2 = 4x+4

c) When x = 5: 3x-2 < 4x+4
d) When x = -2: 3x-2 < 4x+4

6-68)

a. "When you double my number and subtract 9, you get my original number. Victor's number is 9.

b. "When you double my number and add 5, you get 17. Victor's number is 6.

6-65)

a.

Substituting x = -5 into the equation 5x + 8 = 3x - 2, we get:

5(-5) + 8 = 3(-5) - 2

-17 = -17

The equation holds true, which means that x = -5 is a correct solution to the equation.

b.

Substituting x = 4 into the equation 2(x+1) + 6 = 20 - 3x, we get:

2(4+1) + 6 = 20 - 3(4)

16 = 8

The equation does not hold true, which means that x = 4 is an incorrect solution to the equation.


6-66)
To represent Eduardo's age, let's use the variable "E". Since Andy is 4 years older than Eduardo, we can write:

Andy's age = X

Eduardo's age = X - 4

To represent the number of butterflies Eduardo has, let's use the variable "B", and the number of moths as "x". Since the number of butterflies is 12 more than twice the number of moths, we can write:

B = 2x + 12

6-67)
To evaluate the expressions 3x-2 and 4x + 4 for different values of x, we substitute the value of x into the expression and simplify. Then, we compare the two resulting values using <, >, or =.

When x = 0:

3x-2 = 3(0)-2 = -2

4x+4 = 4(0)+4 = 4

-2 < 4, so 3x-2 < 4x+4

When x = -6:

3x-2 = 3(-6)-2 = -20

4x+4 = 4(-6)+4 = -20

-20 = -20, so 3x-2 = 4x+4

When x = 5:

3x-2 = 3(5)-2 = 13

4x+4 = 4(5)+4 = 24

13 < 24, so 3x-2 < 4x+4

When x = -2:

3x-2 = 3(-2)-2 = -8

4x+4 = 4(-2)+4 = -4

-8 < -4, so 3x-2 < 4x+4



6-68)

a. Let's use the variable "x" to represent Victor's number. From the clue, we know that:

2x - 9 = x

Solving for x, we add 9 to both sides and get:

2x = x + 9

Subtracting x from both sides, we get:

x = 9

Therefore, Victor's number is 9.

b. Let's again use the variable "x" to represent Victor's number. From the clue, we know that:

2x + 5 = 17

Solving for x, we subtract 5 from both sides and get:

2x = 12

Dividing both sides by 2, we get:

x = 6

Therefore, Victor's number is 6.

When two tables have a one-to-many relationship, you typically need to add a foreign key to the table on the "many" side to link the records to the corresponding record in the "one" table.

In a one-to-many relationship, the table on the "one" side is usually the primary key table, and the table on the "many" side is usually the foreign key table. The foreign key is used to link the records in the "many" table to the corresponding record in the "one" table. This is done by adding a column to the "many" table that contains the primary key value from the "one" table.

When designing a database, it is important to establish relationships between tables to ensure data integrity and avoid redundant data. In a one-to-many relationship, one record in the primary key table can be associated with many records in the foreign key table. To establish a one-to-many relationship, you need to create a primary key in the "one" table and a foreign key in the "many" table. The foreign key is a column that contains the primary key value from the "one" table. For example, if you have a "customers" table and an "orders" table, the "customers" table would be the primary key table and the "orders" table would be the foreign key table. Each record in the "orders" table would have a foreign key column that contains the customer ID from the "customers" table.

Then we know that we originally had 38 grams of the substance, the rate of growth is 18%, and that the time it was allowed to grow is 6 days. Then we have using the exponential growth model that the amount of the sample after 6 days will be S = P e^rt where P is the initial sample amount, r is the rate of growth, t is the time, and S is the final sample amount. S = 38 e^ .18*6 = 38 e ^ 1.08 = 111.8978 Thus if there were 38 grams of the substance present at the beginning of the study the mass of the sample would be 111.8978 grams after the study.

The correct method to return the sine of 90 degrees is Math.sin(90). The Math.sin() method accepts the angle in radians as its parameter and returns the sine value of that angle. Thus, option B is correct.

In Java, the Math class provides various mathematical functions, including trigonometric functions like sine (sin). Option A, Math.sine(90), is incorrect because there is no method named "sine" in the Math class. The correct name is "sin".

Option C, Math.sin(PI), is incorrect because the constant PI is the value of pi in radians, not in degrees. Since the parameter of the Math.sin() method should be in radians, passing PI as the argument will give the sine of pi radians, not 90 degrees.

Option D, Math.sin(Math.toRadians(90)), is incorrect because the radians () method converts an angle in degrees to radians. So, Math.toRadians(90) would give the value of pi/2 in radians, not 90 degrees.

Option E, Math.sin(Math.PI), is also incorrect for the same reason as option C. Math.PI represents the value of pi in radians, not in degrees.

In conclusion, the correct method to return the sine of 90 degrees in Java is Math.sin(90), which takes the angle in degrees as its parameter. Thus, option B is correct.

Hay 200 botellas de 5 litros y 1000 botellas de 2 litros.

Step-by-step explanation:

Un sistema de ecuaciones lineales es un conjunto de dos o más ecuaciones de primer grado, en el cual se relacionan dos o más incógnitas.

Resolver un sistema de ecuaciones consiste en encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema.

En este caso, las variables a calcular son:

Una empresa aceitera ha envasado 3000 litros de aceite en 1200 botellas de dos y de cinco litros. Entonces es posible plantear el siguiente sistema de ecuaciones:

\(\left \{ {{2*x+5*y=3000} \atop {x+y=1200}} \right.\)

Existen varios métodos para resolver un sistema de ecuaciones. Resolviendo por el método de sustitución, que consiste en despejar o aislar una de las incógnitas y sustituir su expresión en la otra ecuación, despejas x de la segunda ecuación:

x= 1200 - y

Sustituyendo la expresión en la primer ecuación:

2*(1200 - y) + 5*y=3000

Resolviendo se obtiene:

2*1200 - 2*y + 5*y= 3000

2400 +3*y= 3000

3*y= 3000 - 2400

3*y= 600

y= 600÷3

y= 200

Reemplazando en la expresión x= 1200 - y:

x= 1200 - y

x=1200 -200

x= 1000

The repairs have indeed changed the nature of the output of the machine, with an overall improvement in the quality of the parts produced.

To determine if the repairs have changed the nature of the output of the machine, we can compare the percentages of excellent, good, and unacceptable parts before and after the repairs.

Before repairs:
- 80% excellent
- 16% good
- 4% unacceptable

After repairs, we can calculate the percentages based on the sample of 200 parts:
- 157 excellent parts: (157/200) * 100 = 78.5% excellent
- 42 good parts: (42/200) * 100 = 21% good
- 1 unacceptable part: (1/200) * 100 = 0.5% unacceptable

Comparing these percentages, we can see that the output has changed after the repairs:
- Excellent parts decreased from 80% to 78.5%
- Good parts increased from 16% to 21%
- Unacceptable parts decreased from 4% to 0.5%

if the two cities are 45 meters apart in reality, they would be represented as 5 centimeters apart on the map.

The given scale on the map is "cm to 5 m." This means that every centimeter on the map represents 5 meters in reality.

We are told that the two cities are 45 meters apart in reality. To find out how far apart they are on the map, we need to determine the equivalent distance in centimeters.

Since every centimeter on the map represents 5 meters, we can set up a proportion to find the distance on the map:

(cm on the map) / (5 m in reality) = (x cm on the map) / (45 m in reality)

By cross-multiplying and solving for x, we get:

x cm on the map = (cm on the map) * (45 m in reality) / (5 m in reality)

Simplifying the expression, we have:

x cm on the map = 9 * (cm on the map)

This means that every centimeter on the map represents 9 meters in reality.

Therefore, if the two cities are 45 meters apart in reality, they would be represented as 5 centimeters apart on the map.
