mc008-1 jpg 3456 has a degree of 3840.

A degree is a unit of measurement for angles. It is not a SI unit because radians are the SI unit for measuring angles. In general, we measure angles in degrees with a protractor in geometry.

A degree is a unit of measurement for expressing the measurement of an angle. Angles are typically measured in two different units: radians and degrees. Angles are always measured in degrees in practical geometry.

A degree is denoted by the symbol °. (degree symbol). A complete angle in degrees is 360 degrees (sometimes written as 360°), which equals one complete rotation.

As a result, 3456/0.9 = 3840

As a result, mc008-1 jpg 3456 has a degree of 3840.

Answer:

12.5

Step-by-step explanation:

To find the intermediate step in the form of (x+a)=b for the equation x^2+5x+11=13x, we need to first move all the terms to one side of the equation.

x^2+5x+11 = 13x

x^2 - 8x + 11 = 0

To solve this equation, we can factor it.

x^2 - 8x + 11 = 0

(x-11)(x-1) = 0

So, we have two solutions for x: x = 11 and x = 1

To find the intermediate step in the form of (x+a)=b, we can write each solution as (x+a)=b

x = 11, so (x+(-11)) = 11

x = 1, so (x+(-1)) = 1

So, the intermediate step in the form of (x+a)=b for the equation x^2+5x+11=13x is:

(x-11) = 11 and (x-1) = 1

The value of the equation is x² - x - 1 = 0

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

x - ( 1/x ) = 1   be equation (1)

On simplifying the equation , we get

( x² - 1 ) / x = 1

Multiply by x on both sides of the equation , we get

x² - 1 = x

Subtracting x on both sides of the equation , we get

x² - x - 1 = 0

Now , given that ( x / ( x² + 3x - 1 ) ) = 1/4

On simplifying the equation , we get

Cross multiplying the equation , we get

4x = ( x² + 3x - 1 )

Subtracting 4x on both sides of the equation , we get

x² - x - 1 = 0

Hence , the equation is x² - x - 1 = 0

A pound of apples and a pound of oranges each cost $2.50.

Pound is a unit of weight or mass commonly used in the imperial system of measurement. It is equal to 0.453 kilograms and 16 ounces. It is also known as the avoirdupois pound, which is the most commonly used today. In some contexts, the term "pound" may also refer to a unit of currency, the British Pound Sterling (GBP).

This can be determined by subtracting Gina's total cost from Tom's total cost.
Tom's cost was $8.00, and Gina's cost was $5.00, so 8.00 - 5.00 = 3.00. Since Tom bought 3 pounds of apples more than Gina and the same amount of oranges, the cost of the extra apples is $3.00.
Since each pound of apples and oranges costs the same amount,
then $3.00 divided by 3 pounds is $1.00,
so each pound of apples and oranges costs $2.50.

Answer: the most accurate measurement of Pat's temperature in degrees Celsius is 37.3 degrees.

Step-by-step explanation:

The conversion from Fahrenheit to Celsius is C = 5/9 (F-32).

First, we substitute Pat's temperature of 99.3 degrees Fahrenheit into the equation:

C = 5/9 (99.3-32)

C = 5/9 * 67.3

C = 37.3 degrees Celsius

So the most accurate measurement of Pat's temperature in degrees Celsius is 37.3 degrees.

Answer:

37.4 degrees

Step-by-step explanation:

C = 5/9 (F-32)

F = 99.3 so plug F into the equation

C = 5/9 (99.3 - 32)

C = 5/9 (67.3)

5/9 in a calculator = .555 repeating

.555 x 67.3 = 37.35

Rounded = 37.4 degrees

We have from the table provided,

In 8 hours, Team Crusty produced 28 pies.

In 6 hours, Team Pie Peace produced 27 pies.

In 4 hours, Team Crusty produced 20 pies.

In 5 hours, Team Crusty produced 26 pies.

We must divide the number of pies produced by the total time required in order to determine the rate of pies produced.

As a result,

28 pies divided by 8 hours equals 3.5 pies per hour for Team Crusty.

4.5 pies per hour or Team Pie Peace = 27 pies in 6 hours.

20 pies divided by 4 hours yields 5 pies each hour for Team Crusty.

26 pies divided by 5 hours yields 5.2 pies per hour for Team Crusty.

A straight line with a positive and constant slope can be represented by the system of equation 2x + 3y = 5 and 4x + 6y = 7.

The line is a linear equation, which is a line of constant slope. The slope of the line is determined by the coefficients of the variables in the equation.

It can be calculated by dividing the coefficient of the x-term by the coefficient of the y-term. In this example, the slope of the line is calculated by dividing 2/3, which is equal to 0.67.

This indicates that the line has a positive slope. The line is a line of best fit, meaning that it will pass through all the points defined by the two equations. The line will also pass through the point of intersection of the two equations, which is the point (2,1).
