Solve this problem:
㏒₅₄168=?
If:
a = ㏒₇12
b = ㏒₁₂24

Answer:

Step-by-step explanation:

We can start by setting up the following system of inequalities to represent the requirements given in the problem:

x + y ≤ 250 (the total area used should not exceed 250 square feet)

y ≥ 2x (the area used for vegetables should be at least twice the area used for flowers)

To graph these inequalities, we can first graph the boundary lines for each inequality:

x + y = 250 (the boundary line for the first inequality, with points (250, 0) and (0, 250))

y = 2x (the boundary line for the second inequality, with points (0, 0) and (125, 250))

Then, we can shade the region that satisfies both inequalities, which is the region below the line x + y = 250 and to the right of the line y = 2x:

    |

250-|__________________________

    |          /               |

    |         /                |

    |        /                 |

    |       /                  |

    |      /                   |

    |     /                    |

    |    /                     |

    |   /                      |

    |  /                       |

    | /                        |

    |/________________________|

     0          125            250

The shaded region represents all values of x and y that satisfy the requirements given in the problem, where x is the area used for flowers and y is the area used for vegetables. The x and y values in this region can vary, as long as the total area used is less than or equal to 250 square feet and the area used for vegetables is at least twice the area used for flowers.

Answer:

To plot the region that satisfies the requirements, we can start by setting up the inequalities:

y ≥ 2x (the area used for vegetables is at least twice the area used for flowers)

x + y ≤ 250 (the total area used for planting is at most 250 square feet)

We can plot these inequalities on a coordinate plane to find the shaded region:

First, plot the line y = 2x (Load failedboundary line for the first inequality). This line passes through the origin and has a slope of 2, so we can plot additional points using this information. For example, when x = 50, y = 100 (since 100 is twice 50).

So, the shaded region on the coordinate plane corresponds to all values of x and y that satisfy the given requirements.

Answer: the slope of line c is 7/9 because the slope of a line perpendicular is the opposite (reciprocal) of the slope of the original line.

Step-by-step explanation:

In many ways we can use the number -5.

-5 degrees Celsius or -5 degrees Fahrenheit can be used to represent temperatures below freezing. For example, if the outside temperature is -5 degrees Celsius, water will freeze.

Backward Counting: In mathematics, -5 can be used to count backwards from zero. For example, if we subtract 5 from 0, we get -5. This is frequently used when counting down from a starting number, such as in a countdown timer.

Credit Balance: A negative balance or debt owed in a financial account, such as a credit card or loan, can be represented by -5 in accounting. For example, if someone has a -5 dollar credit card balance, it means they owe the credit card company $5. it means they owe the credit card company $5 and have a negative balance on their account.

Answer:

Parallel: m = -3/5
Perpendicular: m = 5/3

Step-by-step explanation:

First let's find the slope of the line.
To do so, we must make [tex]y[/tex] the subject of the line's equation. The slope would then be the coefficient of [tex]x[/tex].

[tex]3x + 5y = -1 \text{ // -3x} \\3x + 5y - 3x = -3x - 1\\\to 5y = -3x - 1 \text{ // :5}\\\\\frac{5y}5 = \frac{-3x - 1}5\\\\y = -\frac35x - \frac15[/tex]

Therefore, the slope of the line is [tex]m = -\frac35[/tex].

Parallel lines have similar slopes, therefore a line parallel to the line 3x + 5y = -1 would have a slope of -3/5.
If a line is perpendicular to our line, then its slope would be the negative invert of our line's slope. Therefore, its slope would be [tex]m = -\left(-\frac35\right)^{-1} \to -\left(-\frac53\right) \to \frac53[/tex]

The amount of sand needed, we will multiply 400 cubic feet by 1.5, which will give us 600 cubic feet of sand needed to fill the space.

The formula for finding the volume of a space is length x width x height. To find the cubic feet of sand needed to fill the space, we will need to calculate the volume of the space in cubic feet and then multiply it by the amount of sand needed to fill the space. To calculate the volume of the space, we will first convert the 6 inches to feet by dividing it by 12, which will give us 0.5 feet. We can then plug the numbers into the volume formula, which will look like this: 20 feet x 40 feet x 0.5 feet = 400 cubic feet. To find the amount of sand needed to fill the space, we will multiply the volume of the space by the amount of sand needed (which is usually 1.5 to 2 cubic feet per square foot). For this example, we will use 1.5 cubic feet. So to find  the amount of sand needed, we will multiply 400 cubic feet by 1.5, which will give us 600 cubic feet of sand needed to fill the space.

sum of the two polynomials is 5x^2 - 5x + 10. The two polynomials we are adding are:

− x 2 + 2 − x 2 + 2 and 3 x 2 − 7 x + 8

A polynomial is an expression consisting of variables and coefficients, combined using only addition, subtraction, and multiplication. The highest power of the variable in a polynomial is called its degree. In this case, both polynomials have degree 2, meaning the highest power of x is x^2.

When adding polynomials, we add the corresponding coefficients for each power of the variable. In this case, we have:

− x 2 + 2 + 3 x 2 = 2x^2

And:

− x 2 + 2 + 3 x 2 − 7 x + 8 = 2x^2 + 2 + 3x^2 - 7x + 8

Answer:

Step-by-step explanation:

To keep the photo in proportion to its negative, you need to maintain the same aspect ratio, which is the ratio of the width to the height of the image. The aspect ratio of the negative is 5.4 cm / 1.35 cm = 4. To maintain this aspect ratio, the aspect ratio of the enlargement must also be 4.

The aspect ratio of the photo paper is 10.2 in / 2.4 in = 4.25. So, the largest length and width that you can use to keep the photo in proportion to its negative is 2.4 in * 4 = 9.6 in and 9.6 in / 4 = 2.4 in, respectively.

Answer:

Step-by-step explanation:

Conversion

First convert the dimensions of the photo paper to centimeters:

[tex]\implies \sf 10.2\;in=10.2 \times 2.54=25.908\;cm[/tex]

[tex]\implies \sf 2.4\;in=2.4 \times 2.54=6.096\;cm[/tex]

Therefore, the dimensions of the photo paper in centimeters are:

To determine the dimensions of the photo if the image is enlarged to fit on a 25.908 × 6.096 cm piece of photo paper, first calculate the scale factor by dividing the shortest side of the photo paper by the shortest side of the negative:

[tex]\sf Scale\;factor=\dfrac{6.096}{1.35}=4.51555...[/tex]

Multiply this scale factor by the longest side of the negative to determine the proportional length of the photo:

[tex]\implies \sf 4.51555...\times 5.4=24.384\;cm[/tex]

As 24.384 cm is less than the longest side of the photo paper, this scale factor will work to keep the photo in proportion to its negative.

Therefore, the largest length and width you can use to keep the photo in proportion to its negative is:

Given the above values relative to the parallelogram, x = 2 and y = 1

A parallelogram is a basic quadrilateral with two pairs of parallel sides in Euclidean geometry. A parallelogram's opposing or facing sides are of equal length, and its opposite angles are of equal measure.

Since the a parallelogram's diagonals are not all the same length, and they connect at the point of junction and have equal sides across the intersection, we can state that:
a

CG = EG and
FG = DG

Thus,
x+2y = 4; .........(1) and

3x-y = 5............(2)

Solving by substitution:

Let's make x the subject of the formula in (1)

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

x = -2y + 4 .......................................(3)

Substitute  (3) into (2)

Where (2)  is 3x-y = 5, thus;

3 (-2y + 4 )-y = 5.

-7y + 12 = 5

-7y + 12 -12 = 5 + -12
-7y = -1 (Divide both sides by -7)

y = 1    .............................(4)

Since y = 1, let's impute this in (1) x+2y = 4

x+2 (1) = 4
x = 4 -2

x = 2

when the price is equal to the market equilibrium price, total surplus is maximized.

What is surplus?

Making the most of society's well-being is a desired goal for an economic system. Do free markets perform that? Buyers must profit from their purchases, and sellers must profit from their sales, in order to provide an answer. Consumer surplus is the difference between the price consumers are willing to pay and the price they actually pay for a commodity or service. When individuals buy something, they typically pay less than they would have otherwise. Similar to producers, sellers might command a higher price for a good than it costs them to make it; this is known as producer surplus because it occurs when the cost of production is less than the price at which the good is sold.

Consumer Surplus = Willingness to Pay Price − Market Price

Producer Surplus = Market Selling Price − Economic Cost

Total Surplus = Consumer Surplus + Producer Surplus

Only the most effective producers will be able to produce a product for less than the market price in highly competitive markets. Therefore, only those vendors will create a good.

Therefore, when the price is equal to the market equilibrium price, total surplus is maximized.

Answer:

we can not assign a floating-point number to a boolean variable

Step-by-step explanation:

The statement "boolean y = 12.5;" is incorrect or "wrong" because it is attempting to assign a floating-point value (12.5) to a boolean data type, which is a type of data that can only represent two values: true or false.

A boolean data type is a fundamental data type in programming and is commonly used in logic and decision-making structures. It is used to represent conditions that are either true or false, and can be used to control program flow, make decisions, and perform logical operations.

In the statement "boolean y = 12.5;", the value 12.5 is a floating-point value, which is a type of data that represents a decimal number with a fractional component. However, a boolean data type is not capable of representing such values, and can only represent two states: true or false.

In programming, attempting to assign a value of the wrong data type to a variable is known as a "type error" or a "type mismatch." Type errors can cause programs to fail, produce unexpected results, or behave in unintended ways.

To fix the statement "boolean y = 12.5;", the data type of the variable "y" should be changed to a data type that can represent decimal values, such as a floating-point data type like "double" or "float." Alternatively, if the intent of the statement was to assign a boolean value to the variable, the value of 12.5 should be replaced with a boolean expression that evaluates to either true or false.

In summary, the statement "boolean y = 12.5;" is incorrect or "wrong" because it attempts to assign a floating-point value to a boolean data type, which is not a valid data type for the value being assigned. Type errors like this can cause programs to fail, produce unexpected results, or behave in unintended ways, and must be corrected to ensure proper program operation.
