The publisher nedds to produce 2414 books and sell so that production cost will equal the money from sales.

Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.

Given:

A small publishing company is planning to publish a new book.

The production costs will include one-time fixed costs (such as editing) and variable costs (such as printing).

The one-time fixed costs will amount to $27,160.

The variable costs will be $8.75 per book.

The publisher will sell the finished product to bookstores at a price of $20.00 per book.

Let x be the number of books.

Cost = 8.75x + 27160

Revenue = 20x

Revenue = cost

20x = 8.75x + 27160

11.25x = 27160

x = 2414.2

x ≈ 2414 books.

Therefore, the required number of books are 2414 books.

Step-by-step explanation:

To be a proper fraction the numerator (top number) must be less the the denominator (bottom number). Let’s start at the top.

27/27

This would be an improper fraction because the numerator is equal to the denominator, not less.

6/17

Because 6 is less then 17 this would make it a proper fraction

A. The thickness of the rectangular sheet of sugar paste is 1/5 cm.

B. The volume of the remaining pastry can be expressed as approximately 45.84 cm³.

The volume of a cuboid is equal to the product of the length, width, and height of a cuboid.

The volume of a cuboid is length × breadth× height

A) The volume of the cuboid pack of sugar paste is 5 cm x 8 cm x 9 cm = 360 cm³.

To find the thickness of the rolled-out rectangular sheet, we need to divide the volume of the pack by the area of the rectangular sheet:

thickness = volume/area

thickness = 360 cm³ / (30 cm x 60 cm)

thickness = 360 cm³ / 1800 cm²

thickness = 1/5 cm

So the thickness of the rectangular sheet of sugar paste is 1/5 cm.

B) The two circular pieces of pastry each have a diameter of 25 cm and thus a radius of 25/2 = 12.5 cm.

The volume of each circular piece of pastry can be calculated as:

V = π × (radius)² × thickness

V = π × (12.5 cm)² × 1/5 cm

V = π × 156.25 × 1/5 cm³

V = 50 × π cm³

Since Mary cuts out two circular pieces, the total volume of pastry that she removes is 2 x 50 x π cm³. The remaining volume of pastry is the original volume of the pack minus the volume of the two circular pieces:

Volume remaining = 360 cm³ - 2 × 50 × π cm³ = 45.84 cm³

The volume of the remaining pastry can be expressed as approximately 45.84 cm³.

Answer: 13

Step-by-step explanation: The two numbers are 967 and 445 making a=4 and b=9. We know a+b= 9+4 which is 13. For starters, you add the last digits of b67 and aa5 so 7+5=12 which is why the four digit number ends in two. When adding, the one from 12 would carry so the second to last digit on the four digit number would have to be 11. To get eleven you would add 7 and 4. The seven comes from the second digit in the b67 number including the one that came from 7+5=12. Now we know a=4. Knowing this now aa5= 445 and 1a12= 1412. We can now substract 445 from 1412 to get 967. b67= 967. To check 967+445=1412.  

The solution is Option C.

The value of the quadratic equation is A = 3a² + 4a - 4 , where the factor of a is given by a = 2/3

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

A = 3a² + 6a - 2a - 4   be equation (1)

On simplifying the equation , we get

A = 3a² + 4a - 4

Now , when the factor of the equation is ( 3a - 2 ) = 0

Adding 2 on both sides of the equation , we get

3a = 2

Divide by 3 on both sides , we get

a = 2/3

Substitute the value of a in the equation , we get

A = 3 ( 2/3 )² + 4 ( 2/3 ) - 4

On simplifying the equation , we get

A = 3 ( 4/9 ) + 8/3 - 4

A = ( 4/3 + 8/3 ) - 4

A = ( 12/3 ) - 4

A = 4 - 4

A = 0

As a result, the coordinate of the picture of point B (4, 9) under dilation with the origin as the center and a scale factor of 2 is (8, 18).

Coordinates are a pair of integers that are used to locate a point or object in a two-dimensional plane. A point's location on a 2D plane is defined by two integers called the x-coordinate and the y-coordinate. The distance between two points is known as the x-coordinate, or abscissa, while the distance between two points is known as the y-coordinate, or ordinate. Point (3, 2), for example, is three units distant from the positive y-axis and two units away from the positive x-axis.

Here,

A dilation with center at the origin and scale factor of 2 will stretch or shrink the distances from the origin by a factor of 2. If the given point B is (4,9), its image under the dilation will be:

(2 * 4, 2 * 9) = (8, 18)

To find the derivative of a piecewise function, you need to take the derivative of each individual piece and then combine them into one piecewise function.

The derivative of each piece can be found using the usual rules of differentiation (such as the power rule, sum rule, product rule, etc.).

Once you have the derivatives of each piece, you can write the overall derivative as a piecewise function, where the expression for each piece is limited to a specific range of x-values. The limits of each piece are defined by the breakpoints in the original function.

For example, if the original function is given as:

f(x) = {x^2 for x < 0,

x for 0 <= x < 1,

2x for x >= 1}

Then the derivative of f(x) can be found as:

Median PQR = PN

Therefore, IM = PN + 2

IM = PN + 2

PN = IM - 2

IM = (15 + 9 + PN)/2

PN = (15 + 9 + IM - 2)/2

15 + 9 + PN = 2IM

15 + 9 + IM - 2 = 2PN

25 + PN = 2IM

25 + IM - 2 = 2PN

PN = 2IM - 25

PN = 2PN - 25

3PN = 25

PN = 25/3

IM = PN + 2

IM = 25/3 + 2

IM = 29/3

Answer: The equation represents the value (in dollars) of a car t years after its purchase, so the purchase price of the car would have been the value of the car when t = 0. Plugging in t = 0 into the equation, we get:

V = 23900 * (0.91)^0

V = 23900

So the purchase price of the car was $23,900.

Regarding the rate of decrease in the value of the car, we can observe that the value decreases at a rate proportional to (0.91)^t, so the rate of decrease is proportional to 0.91.

Step-by-step explanation:

Using the Chinese Remainder Theorem, the smallest positive integer solution is x1 = 62.

We can use the Chinese Remainder Theorem to find the smallest positive integer solution for this problem.

The Chinese Remainder Theorem states that if x ≡ a (mod m) and x ≡ b (mod n), then x is congruent to a unique value modulo mn. That is, there exists a unique solution x such that x is congruent to a modulo m and congruent to b modulo n, and the solution x is between 0 and mn - 1.

So, we want to find the smallest x such that:

x ≡ 6 (mod 8) and x ≡ 7 (mod 9)

We can start by finding a solution x1 such that x1 ≡ 6 (mod 8) and x1 ≡ 7 (mod 9). One such solution is:

x1 = 6 + 8k for some integer k

We can use the formula x1 = 6 + 8k to find a solution x1 that is also congruent to 7 (mod 9):

x1 = 6 + 8k = 7 + 9l (mod 9)

Expanding the right side of this equation, we get:

6 + 8k = 7 + 9l (mod 9)

6 - 7 = 9l - 8k (mod 9)

-1 = 9l - 8k (mod 9)

Since 9 and 8 are relatively prime, we can use the Extended Euclidean Algorithm to find integers r and s such that:

8r + 9s = gcd(8, 9) = 1

Using the Euclidean Algorithm, we can find r = -1 and s = 1. So,

-8 = 9(l - rk) (mod 9)

Since 9 is relatively prime to 8, l - rk is a multiple of 9. We can then rewrite the equation as:

-8 = 9j (mod 9)

Adding 9 to both sides of the equation, we get:

1 = 9j (mod 9)

So, j = 1.

Now, we have:

k = (1 - l) / r

Since r = -1, we can replace k with -l:

k = -l

So, we have:

x1 = 6 - 8l

And,

x1 = 7 + 9l (mod 9)

Combining these two equations, we get:

6 - 8l = 7 + 9l (mod 9)

Subtracting 9l from both sides, we get:

-2l = 13 (mod 9)

Dividing both sides by -2, we get:

l = -13 / -2 = 7 (mod 9)

So,

k = -l = -7 (mod 9)

And,

x1 = 6 - 8(-7) = 6 + 56 = 62 (mod 8)

So,

x1 = 62 (mod 8) and x1 = 7 (mod 9)

The smallest positive integer solution is x1 = 62

A circle having radius 5 and centre at (0,0) has equation x² + y² = 25.

What is the equation of circle?

A circle is a closed curve that extends outward from a set point known as the centre, with each point on the curve being equally spaced from the centre. A circle with a (h, k) centre and a radius of r has the equation:

(x-h)² + (y-k)² = r²

Let (x,y) be any point on the circle.

Given that centre of the circle is origin (0,0).

Now, we know that the distance from any point on the circle to the centre is equal to the radius of the circle.

So, distance between point (x,y) and centre (0,0)  is equal to radius of the circle which is given 5 units.

Now, using the distance formula -

√[(x - 0)² + (y - 0)²] = 5

Squaring on both the sides of the equation -

(x - 0)² + (y - 0)² = 25

So, the equation of the circle with radius 5, centred at the origin is x² + y² = 25.

Therefore, the equation is x² + y² = 25.
