Answer:

720

Step-by-step explanation:

We are looking for the difference between 2/3 and 1/2, which we know to be 120. To subtract fractions of different denominators, we need to find the common denominator (this can be found by finding the LCM of both denominators)

120 = 2/3 - 1/2 = 4/6 - 3/6
1/6 = 120

We can multiply 120 by 6 to find the value of the full bank.

1/1 = 720

The Pythagorean for the triangle with a length of two legs x and y and the hypotenuse length as z is z²=x²+y².

The perpendicular, base (adjacent), and hypotenuse (opposite) are the names of the triangle's three sides. Perpendicular forms a right angle with the triangle base. The hypotenuse is the greatest side opposing the right angle (90 degrees) of a triangle. According to the Pythagorean Theorem, the square of the length of the hypotenuse will always result from adding the squares of the lengths of two legs of a right-angle triangle.

Given the length of one leg is x and the length of another leg is y. The length of the hypotenuse is z. Then, by the Pythagorean Theorem, z²=x²+y².

Here's an example statement in Python that reads an integer variables from standard input and stores it in an existing integer variable called datum:

datum = int(input("Enter an integer value: "))

This statement first prompts the user to enter an integer value by printing the string "Enter an integer value: " to the console. The input() function then reads the user's input from the console as a string. Finally, the int() function converts the string to an integer and assigns the result to the datum variable.

Note that the specific syntax and function calls may vary depending on the programming language being used, but the general concept of reading an integer value from standard input into an existing variable is applicable to most programming languages.

Answer:

  60°

Step-by-step explanation:

The sum of angles in a quadrilateral is 360°. The interior angle adjacent to x will have measure 180°-x. So, the equation can be written ...

  100° +50° +90° +(180° -x°) = 360°

  420° -x° = 360° . . . . simplify

  x = 420 -360 . . . . . . divide by °, add x-360

  x = 60

Answer:

Step-by-step explanation:

Let x be the portion of 60%

180 - x is the portion of 40%

0.60x + 0.40(180 - x) = 0.55(180)

0.60x + 72 - 0.40x = 99

0.20x = 27

x = 135

180 - 135 = 45

First brand = 45 gallons of 40%

Second Brand = 135 gallons of 60%

Answer:

Let's denote:

- The number of orders Diane served as `D`

- The number of orders Sam served as `S`

- The number of orders Boris served as `B`

From the problem, we know:

1. `D + S + B = 54` (the total number of orders they served)

2. `D = S - 6` (Diane served 6 fewer orders than Sam)

3. `B = 2S` (Boris served 2 times as many orders as Sam)

We can substitute equations 2 and 3 into equation 1 to solve for the variables:

Substitute `D` and `B` in equation 1:

`(S - 6) + S + 2S = 54`

Combine like terms:

`4S - 6 = 54`

Add 6 to both sides:

`4S = 60`

Divide by 4:

`S = 15`

Now that we know `S = 15`, we can find `D` and `B` by substituting `S` into equations 2 and 3:

`D = S - 6 = 15 - 6 = 9`

`B = 2S = 2 * 15 = 30`

So, Diane served 9 orders, Sam served 15 orders, and Boris served 30 orders.

Step-by-step explanation:

In this question we are given with ,

And we're asked to find the perimeter of rectangle .

Solution : -

We know that ,

\( \pink{ \boxed{\sf{Area \: of \: rectangle = L × W}}}\)

Where ,

So from this formula we can find the width of rectangle and equating it with 92 ( because 92 is the given area ) . Substituting value of length :

\( \longmapsto \: 11.5 \times W = 92\)

Step 1 : Multiplying 11.5 and W :

\( \longmapsto \: 11.5W = 92\)

Step 2 : Dividing by 11.5 on both side :

\( \longmapsto \: \frac{ \cancel{11.5}W}{ \cancel{ 11.5}} = \frac{92}{11.5} \)

On further calculations we get :

\( \longmapsto \: W = \cancel{\frac{920}{115} }\)

Step 3 : By cancelling 920 by 115 we get :

\( \longmapsto \: \purple{\boxed{ \bold{W = 8 \: mm}}}\)

We know that ,

\( \blue{ \boxed{ \sf{Perimeter \: of \: rectangle = 2 ( L +W )}}}\)

Where ,

Substituting values in formula :

\( \longrightarrow \: 2(11.5 + 8)\)

Step 1 : Solving parenthesis :

\( \longrightarrow \: 2(19.5)\)

Step 2 : Multiplying 2 with 19.5 :

\( \longrightarrow \: \green{\boxed{ \bold{39 \: mm}}}\)

Answer:

Width = 108 cm

Step-by-step explanation:

Perimeter =  2 x (length + width)

148.5 = Length + width

Ratio of Length to Width = 3 : 8

Sum of ratio = 11

\(Length = \frac{3}{11} \times 148.5 = 40.5 \ cm\\\\Width = \frac{8}{11} \times 148.5 = 108 \ cm\)

Answer: 162°

Answer:

133,860

Step-by-step explanation:

The baker was going to sell his house for 145,500 but he found that no one came to buy, so he decreased the amount by "8%".

* No we have our key elements:

- Starting amount = 145,500

- Rate of change = 8%

* We will get the "8%" of the number 145,500

- Firstly, "8%" means 8/100

- So, 0.08 will be our new rate of change.

* 145,500 will be multiplied by 0.08 to find the final answer because when we talk about the percentage of a number, we are going to talk about a part of it.

- 145,500 × 0.08 = 133,860 ; the same as

145,500 × 8/100 = 133,860

The possible price for the items if the store sells $600 is (c) $40

From the question, we have the following parameters that can be used in our computation:

The supply-demand graph

If the store sells $600, then there is a supply worth of $600

The equation of the supply line is calculated as

y = mx + c

Where

c = y = 0

i.e. c = 100

So, we have

y = mx + 100

Using another point on the graph, we have

30m + 10 = 400

So, we have

m = 13

This means that

y = 13x + 100

For a supply of 600, we have

13x + 100 = 600

So, we have

13x = 500

Divide by 13

x = 38.4

Approximate

x = 40

Hence, the possible price for the items is (c) $40

Step-by-step explanation:

The slope of the line is 2.

Slope is a measure of the steepness of a line or a surface. In geometry and mathematics, slope refers to the rate at which a line rises or falls as it moves horizontally. It is calculated as the ratio of the vertical change between two points on a line (the rise) to the horizontal change between those same two points (the run).

The slope of a line can be expressed as a fraction or a decimal. A positive slope indicates that the line is increasing as it moves from left to right, while a negative slope indicates that the line is decreasing as it moves from left to right. A slope of zero indicates a horizontal line, and a slope that is undefined indicates a vertical line.

In real-world applications, slope is used in a variety of fields, such as physics, engineering, and architecture. For example, slope is used to calculate the angle of a roof or a ramp, the rate of change in the value of a stock or a commodity, or the rate of change of a moving object. Understanding slope is an important concept in mathematics and has many practical applications in the real world.

The slope of a line passing through two points (x1, y1) and (x2, y2) is given by the formula:

m = (y2 - y1) / (x2 - x1)

Here, the given two points are (0, 2) and (-1, 0). Substituting these values into the slope formula, we get:

m = (0 - 2) / (-1 - 0) = (-2) / (-1) = 2

Therefore, the slope of the line is 2.

Matrices A and B are non-invertible matrices that can be added together to form an invertible matrix. To find these matrices, we can use the following steps:

Step 1: Choose a matrix A that is not a diagonal matrix and is not invertible. One example of such a matrix is

\(A = \left[\begin{array}{ccc}1&1\\0&0\end{array}\right]\)

Step 2: Choose a matrix B that is not a diagonal matrix, is not invertible, and is not a scalar multiple of matrix A. One example of such a matrix is
\(B = \left[\begin{array}{ccc}0&0\\1&1\end{array}\right]\)

Step 3: Add the matrices A and B together to form the matrix A+B. This matrix will be invertible, as shown below:

\(A+B = \left[\begin{array}{ccc}1&1\\0&0\end{array}\right]+\left[\begin{array}{ccc}0&0\\1&1\end{array}\right]=\left[\begin{array}{ccc}1&1\\1&1\end{array}\right]\)

Step 4: Verify that the matrix A+B is invertible by finding its determinant. The determinant of a 2x2 matrix is given by:

det(A+B) = (1)(1) - (1)(1) = 0

Since the determinant of the matrix A+B is not equal to zero, the matrix is invertible.

Therefore, the matrices \(A = \left[\begin{array}{ccc}1&1\\0&0\end{array}\right]\) and \(B = \left[\begin{array}{ccc}0&0\\1&1\end{array}\right]\) are non-invertible matrices that can be added together to form an invertible matrix \(A+B =\left[\begin{array}{ccc}1&1\\1&1\end{array}\right]\).
