Therefore , as a result, the answer to the provided linear equation is 5/23 pounds of cashews and 13/46 pounds of peanuts.

A linear equation is characterized as having a max of just one degree. A Any equation with a maximum degree of 2 or above is considered to be nonlinear. A graph with a linear equation has a straight line. A curve is created on the graph by a nonlinear equation.

Here,

Half of x is equal to the weight of peanuts,

so if x is the weight in pounds of cashews.

Ours has

=>5.75 x + 2.30 (1/2 x)

=>575x+115−230x =190

=> 1.90 x=75/345 = 5/23 pounds of cashews

Pounds of peanuts:

=> 1/2−x=23/46 −10/46= 13/46

Answer:

The area of a circle is given by the formula A = πr^2, where A is the area, r is the radius, and π is approximately equal to 3.14. Since the diameter of the dartboard is 30 millimeters, the radius is half of that, or 15 millimeters. Therefore, the area of the dartboard is A = π(15^2) = 225π square millimeters.

Step-by-step explanation:

The figure shows intersecting lines k and m, the measure of angle a is 94 degrees.

What are parallel lines ?

parallel lines can be defined as the lines which are equi distant from each other and which never meet or intersect each other.

Given,

In the figure the lines k and m are intersecting.

so,

by adding 86 degrees with a it should result into 180 degrees.

86+a  = 180

a = 180 - 86

a = 94

Hence, The figure shows intersecting lines k and m,  the measure of angle a is 94 degrees.

The value of k from the equation is k = 4

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

f ( x ) = ( 2 - k ) / ( 5x + k )   be equation ( 1 )

Now , the equation passes through the point P ( 3 , -2/19 )

On simplifying the equation , we get

Substituting the values of x and y in the equation , we get

y = ( 2 - k ) / ( 5 ( 3 ) + k ) )

-2/19 = ( 2 - k ) / ( 15 + k )

Multiply by ( 15 + k ) on both sides of the equation , we get

-2 ( 15 + k ) / 19 = 2 - k

Multiply by 19 on both sides of the equation , we get

-30 - 2k = 38 - 19k

Adding 2k on both sides of the equation , we get

38 - 17k = -30

Subtracting 38 on both sides of the equation , we get

17k = 68

Divide by 17 on both sides of the equation , we get

k = 4

Hence , the value of k = 4

Answer:

4.2571428571 (but you should probably round for 4.3 or 4.26)

Step-by-step explanation:

if he spent $7.45 and each pound costs $1.75 then just divide 7.45 by 1.75.

Anthony bought exactly 4.2571428571 pounds of trail mix. However, it can be rounded off to 4.3 pounds.

The total amount spent on trail mix= $7.45

1 pound of trail mix costs $1.75

Therefore, the amount of trail mix bought= total amount spent on it / the cost of 1 pound of the product

= 7.45 / 1.75

= 4.2571428571 pounds

If there were 50 workers, they would set 2,500 stones each day.

Total number is a term used to describe the sum of all the values or items within a set. It is usually used to calculate an aggregate or grand total, such as the sum of all the numbers in a list or the total number of people in a population. Total number can also be used to describe the absolute value or quantity of something, such as the total number of days in a year.

Assuming each worker set the same number of stones each day, the total number of stones set each day would be 50 times the number of workers. For example, if there were 20 workers, they would set 1,000 stones each day.
The number of stones set each day could also vary depending on the number of workers and the number of days they worked in a week. For example, if the workers worked a six day week and worked 50 out of the 52 weeks each year, the total number of stones set each day would be 50 times the number of workers multiplied by six. For example, if there were 20 workers, they would set 12,000 stones each day. If there were 50 workers, they would set 30,000 stones each day.

The number of stones set each day can also be affected by the production rate of the workers, the quality of the stones, and the amount of time required to set each stone. If the production rate was low, the number of stones set each day would also be lower. Similarly, if the quality of the stones was poor, the workers would likely take longer to set each stone, thus reducing the number of stones set each day.

Overall, the exact number of stones set each day depends on the number of workers, the number of days they work each week, their production rate, and the quality of the stones.

Answer:

To divide using long division, we first divide the leading term of the dividend (3r³) by the leading term of the divisor (r) to get the first term of the quotient (3r²). Then, we multiply the divisor (r + 4) by the quotient term (3r²) and subtract it from the dividend. We then bring down the next term of the dividend (11r²) and repeat the process. This will give us the quotient and the remainder.

The long division process is as follows:

(r + 4) | (3r³ +11r²-6r-18)

| 3r² (3r²)

|__

| -9r² +11r²-6r-18

|____

| -2r-18

|____

| +12r + 72

|____

| -36

|____

So the quotient is 3r² - 2r + 12 and the remainder is -36

And we can write the division as (3r³ +11r²-6r-18)÷(r + 4) = 3r² - 2r + 12 +(-36)/(r + 4)

The degree of the function is 3, and the end behavior is that as x gets very large or very small the function increases or decreases without bound respectively.

Generally, The degree of a polynomial function is the highest power of the variable in the function. In this case, the highest power of x is 3, so the degree of the function is 3.

The end behavior of a polynomial function refers to how the function behaves as the value of x gets very large or very small (i.e., as x approaches positive or negative infinity).

To find the end behavior, we look at the leading term, which is the term with the highest degree. In this case, the leading term is 3x³. Since the coefficient of x³ is positive, the end behavior of the function as x approaches positive infinity is positive infinity, and as x approaches negative infinity, the end behavior of the function is negative infinity.

The given statement "when a transversal crosses two parallel lines, Corresponding angles are created, which are congruent to one another" is TRUE.

The angles created when a transversal intersects two parallel lines are known as corresponding angles.

Typical examples of equivalent angles include opening and closing a lunchbox, resolving a Rubik's cube, and endless parallel railroad tracks.

Angles that are equal in size and are found on the same side as the transversal line are called corresponding angles.

In geometry, corresponding sides and corresponding angles of polygons are compared as part of the tests for congruence and resemblance.

In these tests, the order of adjacency is maintained by pairing each side and each angle of one polygon with a side or angle of the other polygon.

Therefore, the given statement "when a transversal crosses two parallel lines, Corresponding angles are created, which are congruent to one another" is TRUE.

Next we have to find the area of the triangle, and then subtract it by the area of the rectangle to find the area of the figure. To find the area of a triangle, we do BaseXHeight divided by 2, and in this problem, we do 9X2 (which is 18) and 18 divided by 2 which gets us 9. Now we subtract 9 from 45, which gets us 36 which means 36m2 is the answer to this problem.

The slope is (2/3 - 2/(3+h))/ h and as h is made closer and closer to 0, the slopes of the lines tend toward the derivative of the function f(x) at x = 3.

a) To find the slope of the line between the points (3, f(3)) and (3.1, f(3.1)), we use the formula m = (f(3.1) - f(3)) / (3.1 - 3) = (f(3.1) - f(3)) / 0.1

b) To find the slope of the line between the points (3, f(3)) and (3.01, f(3.01)), we use the formula m = (f(3.01) - f(3)) / (3.01 - 3) = (f(3.01) - f(3)) / 0.01

c) To find the slope of the line between the points (3, f(3)) and (3.001, f(3.001)), we use the formula m = (f(3.001) - f(3)) / (3.001 - 3) = (f(3.001) - f(3)) / 0.001

As h is made closer and closer to 0, the slopes of the lines tend toward the derivative of the function f(x) at x = 3.

Now to find a simplified rational expression for the slope of the line between (3, f(3)) and (3 + h, f(3 +h)), (h 0) :

The slope is equal to (f(3+h) - f(3)) / h

With f(x) = 2/x, we substitute it into the equation above and we get (2/(3+h) - 2/3) / h

The simplified rational expression for the slope is (2/3 - 2/(3+h))/ h
