Answer:

\(y = \frac{1}{5}x + 5\)

Step-by-step explanation:

20y - 4x = 100

20y= 4x + 100

Divide everything by 20

20y/20 = y

4x/20 = 1/5x

100/20 = 5

y = 1/5x + 5 (that's the answer)

\(20y - 4x = 100\\20y = 4x + 100\\\frac{20y}{20} = \frac{4x}{20} +\frac{100}{20} \\y= \frac{1}{5}x +5\)

If you rolled two dice, recorded the face values and summed them up, you would be collecting quantitative data. This is because quantitative data is numerical in nature and involves counting, measuring or quantifying something.

In this case, the numbers on the faces of the dice would be counted and added together to obtain a total sum. This data can be further classified as discrete since the possible outcomes of rolling dice are limited to a set of discrete values.

Therefore, this data can be easily analyzed using statistical methods to determine the probability of certain outcomes occurring. Collecting quantitative data is essential in many fields such as science, economics, and finance, as it provides valuable insights into the behavior and trends of various phenomena.

In this situation, the face values on the dice represent numbers, and the sum of these values is also a number. The data you collect can be analyzed using statistical methods and can provide meaningful insights.

Step-by-step explanation:

Kara can make 224 cups of coffee from the 28 oz package, given that 1/8 oz of coffee is needed to make 1 cup.

To calculate the number of cups of coffee that can be made from a 28 oz package, we need to determine how many 1/8 oz portions are present in 28 oz. First, we calculate the number of 1/8 oz portions in 28 oz. Since 1 cup requires 1/8 oz, the number of cups can be found by dividing 28 oz by 1/8 oz:

Number of cups = 28 oz / (1/8 oz) = 28 oz * (8/1 oz) = 224 cups.

Therefore, the 28 oz package of coffee can make 224 cups of coffee. This calculation assumes that all of the coffee is used and none is wasted or lost during the brewing process.

To determine which set of data most likely has a mean closest to 29.5, we need to analyze the shape and position of the histograms in relation to the value 29.5.

Looking at the histograms described:

The first histogram ranges from 9 to 48, and the upward trend starts from 1 and ends at 33, followed by a downward trend. This histogram suggests that there may be values lower than 29.5, which would bring the mean below 29.5.

The second histogram ranges from 15 to 48, with an upward trend from 1 to 30 and then a downward trend. Similar to the first histogram, it suggests the possibility of values lower than 29.5, indicating a mean below 29.5.

The third histogram ranges from 12 to 56, and the upward trend starts from 1 and ends at 32, followed by a downward trend. This histogram covers a wider range but still suggests the possibility of values below 29.5, indicating a mean below 29.5.

The fourth histogram ranges from 15 to 54 and exhibits multiple trends. While it has fluctuations, it covers a wider range and includes both upward and downward trends. This histogram suggests the possibility of values above and below 29.5, potentially resulting in a mean closer to 29.5.

Based on the descriptions, the fourth histogram, with its more varied trends and wider range, is most likely to have a mean closest to 29.5.

Step-by-step explanation:

A  quadratic equation in math is nothing but an equation of the form ax² + bx + c = 0

We know that a quadratic equation is nothing but a polynomial equation of the second degree.

The standard form of quadratic equation is ax² + bx + c = 0, where a and b are the real valued coefficients, x is the variable.

In the above equation, the value of 'a' can not be zero (a ≠ 0) in order to be a quadratic equation.

The coefficient 'a' is called as leading coefficient of quadrtic equation, c is called as constant term, and 'b' is the middle term.

In order to determine the type of roots a quadrtic equation may have, first we find the value of   b² - 4ac

If b² - 4ac > 0, then the equation has two distinct real roots.

If b² - 4ac = 0 then the equation has one real root.  

And if b² - 4ac < 0 then in this case, the equation does not have real roots.

Answer:

First, we can write:

x = 2 . ¯ 3

Next, we can multiply each side by  10 giving:

10 x = 23 . ¯ 3

Then we can subtract each side of the first equation from each side of the second equation giving:

10 x − x = 23 .¯ 3 − 2 . ¯ 3

We can now solve for  x  as follows:

10 x − 1 x = ( 23 + 0 . ¯ 3 ) − ( 2 + 0 . ¯ 3 )  ( 10 − 1 ) x = 23 + 0 . ¯ 3 − 2 − 0 . ¯ 3  

9 x = ( 23 -2 ) + ( 0 . ¯ 3 − 0 . ¯ 3 )  

9 x = 21 + 0

9 x = 21

9 x /9 = 21 /9

9 x /9 = 3 × 7 /3 × 3

x = 3 × 7 /3 × 3

x = 7 /3

The value of the third side of the triangle, that is x is 24.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.

The given triangle is a right- angles triangle.

Use the Pythagorean theorem to find the third side of the triangle.

The Pythagorean theorem is given by the following formula:

a^2 + b^2 = c^2

10^2 + b^2 = 26 ^2

100 + b^2 = 676

b^2 = 676 - 100

b^2 = 576

Answer:

When we add two or more whole numbers, their sum is the same regardless of the order of the addends. The sum of both 2 + 4 and 4 + 2 is 6. That means, we can add whole numbers in any order. When three or more numbers are added, the sum is the same regardless of the grouping of the addends.

Step-by-step explanation:

there

There are four mathematical properties which involve addition. The properties are the commutative, associative, identity and distributive properties.

Commutative Property: When two numbers are added, the sum is the same regardless of the order of the addends.

For example 4 + 2 = 2 + 4

To remember the commutative property, it might be helpful to think about the word commute which means to switch places between home and work (or home and school). In the example above, you can see the 4 and the 2 commuting or switching places.

Associative Property: When three or more numbers are added, the sum is the same regardless of the grouping of the addends.

For example (2 + 3) + 4 = 2 + (3 + 4)

To remember the associative property, it might be helpful to think about the word associate, which as a verb means to interact with a group (maybe you associate with a certain group of friends!). The parentheses are grouping operators, that is, they form groups of numbers and operations. You can see in the example above, the 3 can associate with either the 2 or the 4, but the value of each side is still a total of 9.

Identity Property: The sum of any number and zero is the original number.

For example 5 + 0 = 5.

To remember the identity property, it might be helpful to think of it as a question and answer: What number can I add so that the value is not changed? Zero. In the example above, the 5 gets to keep its identity because adding zero does not change its value.

Distributive Property: The sum of two numbers times a third number is equal to the sum of each addend times the third number.

For example 4 * (6 + 3) = 4*6 + 4*3

The distributive property is the only property that combines multiplication and addition. That makes it very important!

The net work output of the turbine in the ideal Brayton cycle is approximately -1593.11 kJ/kg.

To find the net work output of the turbine in an ideal Brayton cycle, we need to use the cold air standard assumptions. These assumptions include:

Given:

Initial temperature of air entering the turbine (T₁) = 1200 °C

Pressure ratio (P₂/P₁) = 7:1

Let's calculate the net work output using the following steps:

Step 1: Convert the initial temperature to Kelvin.

T₁ = 1200 °C + 273.15 = 1473.15 K

Step 2: Calculate the polytropic exponent (n) using the specific heat ratio (γ).

For air, γ ≈ 1.4 (approximately)

n = 1 / (γ - 1) = 1 / (1.4 - 1) = 1 / 0.4 = 2.5

Step 3: Calculate the temperature ratio (T₂/T₁) using the pressure ratio (P₂/P₁) and polytropic exponent (n) in turbine.

T₂/T₁ = (P₂/P₁)^((γ-1)/γ) = (7/1)⁰.⁴ ≈ 2.0736

Step 4: Calculate the final temperature (T₂) by multiplying it with the initial temperature.

T₂ = T₁ * (T₂/T₁)

= 1473.15 K * 2.0736

≈ 3051.74 K

Step 5: Calculate the net work output (W_net) using the isentropic turbine equation.

W_net = Cp * (T₁ - T₂)

Here, Cp is the specific heat at constant pressure for air. Assuming constant specific heat values for air:

Cp ≈ 1.005 kJ/kg·K (approximately)

W_net = 1.005 * (1473.15 - 3051.74) kJ/kg

W_net ≈ -1593.11 kJ/kg (negative sign indicates work extraction)

Therefore, the net work output of the turbine in the ideal Brayton cycle is approximately -1593.11 kJ/kg.

Answer: Center: (9,-5), Radius = 9

Answer:

centre = (9, - 5 ) and radius = 9

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

given

x² + y² - 18x + 10y + 25 = 0

subtract 25 from both sides and collect x / y terms together

x² - 18x + y² + 10y = - 25

using the method of completing the square

add ( add half the coefficient of the x/ y terms )² to both sides

x² + 2(- 9)x + 81 + y² + 2(5)y + 25 = - 25 + 81 + 25

(x - 9)² + (y + 5)² = 81 = 9²

then

centre = (9, - 5 ) and radius = 9
