Answer:

The width of the rectangle is [tex]5xy^3[/tex].

Step-by-step explanation:

The area of a rectangle is the product of length and width of the rectangle.

[tex]A=length\times width[/tex]

It is given that the area of the rectangle is [tex]15x^3y^4[/tex] square meters and the length of the rectangle is [tex]3x^2y[/tex].

[tex]15x^3y^4=3x^2y\times width[/tex]

[tex]width=\frac{15x^3y^4}{3x^2y}[/tex]

[tex]width=\frac{3\times 5\times x^2\times xy^3\times y}{3x^2y}[/tex]

Cancel out common factors 3x²y.

[tex]width=5xy^3[/tex]

Therefore the width of the rectangle is [tex]5xy^3[/tex].

Answer:

The cost of soft pretzel is $1.25

Step-by-step explanation:

Let $x be the price of one slice of pizza and $y be the price of one soft pretzel.

1. 9 slices of pizza cost $9x and 5 soft pretzels cost $5y. Together they cost $33.25, then

9x+5y=33.25.

2. 4 slices of pizza cost $4x and 6 soft pretzels cost $6y. Together they cost $19.50, then

4x+6y=19.50.

3. Solve the system of two equations:

[tex]\left\{\begin{array}{l}9x+5y=33.25\\4x+6y=19.50\end{array}\right..[/tex]

Multiplythe first equation by 4, the second equation by 9 and subtract them:

[tex]4(9x+5y)-9(4x+6y)=4\cdot 33.25-9\cdot 19.50,\\ \\36x+20y-35x-54y=133-175.5,\\ \\-34y=-42.5,\\ \\y=\$1.25.[/tex]

Then

[tex]4x+6\cdot 1.25=19.50,\\ \\4x=19.50-7.50,\\ \\4x=12,\\ \\x=\$3.[/tex]

Answer: Each soft pretzel cost $1.25

Step-by-step explanation:

Hi, we have to write an equation for each case:

9 x + 5 y = 33.25

4x +6 y = 19.50

Where x is the price of 1 slice of pizza, and y is the price of each soft pretzel.

Multiplying the first equation by 4, and the second equation by 9

36x +20y =133

36x +54y =175.5

And subtracting the first equation to the second equation

36x +54y =175.5

-

36x +20y =133

____________

34 y = 42.5

Solving for y  

y =42.5/34

y = $1.25

Each soft pretzel cost $1.25

Step-by-step explanation:

Answer: If the rate of change is $1 = 78p, then if you have 160p, how much dollars you will get?

(if p are penys)

100p = 1 pound

if $1 = 78p = 0.78 pound

→ 1  pound = $1/0.78 = $1.28

→ 160*1 pound = $160/0.78 = $205.13

So if you change 160 pounds, you will get 205 dollars and 13 cents.

The number of dollars when 160 pounds is exchanged will be 205.13.

You may multiply the pounds by the exchange rate to get how many dollars you will receive for 160 pounds if the exchange rate is $1 = 78p.

160 pounds multiplied by the 78p to the dollar conversion rate results in:

160 pounds multiplied by 100 pence equals 16,000 pence.

Since there are 100 pence in a pound, we divide the amount in pence by 100 to get dollars:

16,000 p divided by 78p is $205.13

Consequently, if you convert 160 pounds to dollars at the current exchange rate of $1 = 78p, you will get around 124.80 dollars in return.

Final answer:

Marcus's final elevation after the hike, starting from 3712 feet and dropping 50 feet, is 3662 feet.

Explanation:

Marcus starts his hike at an elevation of 3712 feet. If the trail drops 50 feet in elevation from beginning to end, we can find his final elevation by subtracting that drop in elevation from his starting elevation.

The calculation would be:
Starting elevation - Elevation drop = Final elevation

So, it will look like this:
3712 feet - 50 feet = 3662 feet

Therefore, Marcus's final elevation would be 3662 feet.

The polynomial x³-2x²+x-2 can be completely factorized by applying the technique of grouping and difference of squares, resulting in the complete factorization as (x-2)(x-1)(x+1).

The complete factorization of the polynomial x³-2x²+x-2 can be found by first factorizing it into simpler polynomials. The given polynomial can be rewritten as x³-2x²+x-2. It is now possible to apply grouping, pair the terms as (x³-2x²) and (-x²+x-2). This gives us x²(x-1)-1(x-2). Now, you can clearly see that you have a common factor (x-1) that you can take out from each set. This gives you your final answer of (x-2)(x²-1). Then apply further factorization on x²-1 to get (x+1)(x-1), because x²-1 is a difference of two squares. So, the complete factorization is (x-2)(x-1)(x+1).

The complete factorization of the polynomial x^3 - 2x^2 + x - 2 is (x + 1)(x - 1)(x - 2).

The polynomial x^3 - 2x^2 + x - 2 can be factorized completely by using the Rational Root Theorem and synthetic division.

By testing various factors of the constant term -2 (±1 and ±2) and the leading coefficient 1, we find that x = -1 is a root of the polynomial.

Using synthetic division, we can divide the polynomial by (x + 1) to obtain the quotient x^2 - 3x + 2. This quadratic polynomial can be further factorized as (x - 1)(x - 2).

Therefore, the complete factorization of the original polynomial is (x + 1)(x - 1)(x - 2).

Answer:46

Step-by-step explanation:Regular polygons are shapes made of straight lines with certain relationships among their lengths. For instance, a square has 4 sides, all the same length. A regular pentagon has 5 sides, all the same length. For these shapes, there are formulas for finding the area. But for irregular polygons, which are made of straight lines of any length, there are no formulas, and you need to be a little creative to find the area. Fortunately, any polygon may be divided into triangles, and there is a simple formula for the area of triangles.

Label the vertices (points) of the polygon starting with 1 at an arbitrary vertex and continuing clockwise around the polygon. There should be as many vertices as there are sides. E.g. for a pentagon (five sides) there will be five vertices.

Draw a line from vertex 1 to vertex 3. This will make one triangle, with vertices 1, 2, and 3. If there are only 4 sides, it will also make a triangle with vertices 1, 3 and 4.If the polygon has more than 4 sides, draw a line from vertex 3 to vertex 5. Continue in this way until you run out of vertices.

Compute the area of each triangle. The formula for the area of a triangle is 1/2 * b * h, where b is the base and h is the height.

Add up the areas, and this is the area of the polygon.

Answer:

98 sq yd

Step-by-step explanation:

46 is NOT the right ans n the method of dividing into triangles is not the best way.

the polygon is a rectangle minus a triangle.

the triangles sides are 3,4 n 5

it is a right-angle triangle cuz' 3^2 + 4^2 = 5^2

so the triangle area = base x height /2

= 3x4/2 = 6

rectangle area = length x width

= 13*8 = 104

so the polygon's area = 104 - 6

= 98 sq yd

Answer:

Estimate is 150 and actual product is 138.

Step-by-step explanation:

To estimate products, we round the numbers to nearest unit place, 10th, 100th, 1000th, and so on.

Given are the numbers 3 and 46.

We can round 46 ≈ 50.

So Estimation would be 3 x 46 ≈ 3 x 50

3 times 5 is 15 and we can add zeros after it.

So estimation is 3 x 46 ≈ 150.

Now actual product would be...

3 times 6 is 18, so we note down 8 and 1 goes to carry over 4.

3 times 4 is 12 and carry 1 will be added in it, so 12 + 1 = 13.

It means the actual product is 3 x 48 = 138.

Answer: Two sides are 7in, and the two other sides are 9.5 in.

Step-by-step explanation:

Since there are two sides that will be longer than the other two, 2.5 will be subtracted twice:

33in -2.5in -2.5in = 28in

Since there are 4 sides, 28in is divided by 4:

28in/4 = 7in

To find the 2 larger sides, add 2.5 back to the side length:

7in +2.5in = 9.5in

Parallelogram is a closed shaped quadrilateral in which the opposite sides are equal and parallel. The length of the parallelogram tile of the shorter side is 7 in and the length of the longer side is 9.5 in.

A store sells tiles in the shape of a parallelogram.

The perimeter of each tile is 33 inches.

One side of each tile is 2.5 inches longer than another side.

Parallelogram is a closed shaped quadrilateral in which the opposite sides are equal and parallel. As the opposite sides are equal in parallelogram thus the perimeter of the parallelogram is twice the sum of the two different sides.

Let l be the length of the shorter side. Thus longer side will be (2.5+l ).

The question is about coordinates on a coordinate plane, and the answer explains the concept of a coordinate plane and how to interpret coordinates.

The given question provides a set of coordinates: P(-4, 2), Q(6, 4), R(11, -2), and S(2, -3). These coordinates represent points on a coordinate plane.

In mathematics, a coordinate plane is a two-dimensional plane formed by two number lines, the horizontal x-axis and the vertical y-axis. The x-coordinate represents the horizontal position of a point, and the y-coordinate represents the vertical position of a point.

For example, point P is located at -4 on the x-axis and 2 on the y-axis. Similarly, point Q is at 6 on the x-axis and 4 on the y-axis. By understanding the coordinates of each point, we can determine their positions on the coordinate plane.

Answer:

n=6

Step-by-step explanation:

n= the amount of boxes he needs

so if he puts 30 toys in each box out of 180 you divide 180 by 30 and you get your answer.

so the amount of boxes he needs = 6

Final answer:

To find the number of boxes needed to pack 180 cat toys with 30 toys in each box, divide the total number of toys by the number of toys per box to get the answer of 6 boxes.

Explanation:

The number of boxes Aroon needs can be calculated by dividing the total number of cat toys by the number of toys packed in each box.

Let n represent the unknown factor, which is the number of boxes he needs.

The equation representing this situation is n = 180 ÷ 30.

Solving n = 6, Aroon needs 6 boxes to pack all 180 cat toys.

To find the perimeter of a rectangle in terms of x, add up the length and width and multiply by 2.

The perimeter of a rectangle can be found by adding up all four sides. In this case, the length and width of the rectangle are represented by the factors of the area measure:

10x² + 13x - 3 = (2x - 1)(5x + 3)

So the length is (2x - 1) and the width is (5x + 3). The perimeter can be calculated using the formula:

Perimeter = 2(length + width)

Substituting the values, the perimeter in terms of x is:

Perimeter = 2((2x - 1) + (5x + 3))

Simplifying further:

Perimeter = 2(7x + 2)

Perimeter = 14x + 4
