Final answer:

The cabinet is 52 inches tall and the football team scored 5 field goals.

Explanation:

1)To find out how tall the cabinet is with 4 drawers each being 13 inches tall, you would multiply the number of drawers by the height of each drawer. So it would be 4 drawers into 13 inches per drawer.
2)For the football team scoring question, since a field goal is worth 3 points and the team scored 15 points from field goals, you would divide the points scored by field goals by the number of points a single field goal provides. It would be 15 points ÷ 3 points per field goal.

Answers:

1)The cabinet is 52 inches tall.

2)The team scored 5 field goals.

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 ).

Now the perimeter [tex]P[/tex] of the parallelogram tile can be given as,

[tex]P=2[l+(2.5+l)}[/tex]

[tex]33=4l+5[/tex]

[tex]4l=33-5[/tex]

[tex]l=\dfrac{28}{4}[/tex]

[tex]l=7[/tex]

Thus the length of the parallelogram tile of the shorter side is 7 in and the length of the longer side is 9.5 in.

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:

slope =4

Step-by-step explanation:

The slope intercept equation of a line is written in the form

y= mx+b

where m is the slope and b is the y intercept.

Since y =4x+5 is written is this form, we can see that 4 is the slope and 5 is the y intercept

4x - 3y = 16

x + y = -3

Subtract y from both sides of the 2nd equation.

x = -3 - y

Now that we have a value of x, we can plug it into the first equation to solve for y.

4(-3 - y) - 3y = 16

Distributive property.

-12 - 4y - 3y = 16

Combine like terms.

-12 - 7y = 16

Add 12 to both sides.

-7y = 28

Divide both sides by -7.

y = -4

The value of y is -4, and now we can solve for the value of x.

Plug this value into either equation.

x + (-4) = -3

Add 4 to both sides.

x = 1

The value of x is 1.

To solve the linear equations 4x-3y=16 and x+y=-3, we can use substitution. The solution is x = 1 and y = -4.

To solve the linear equations 4x-3y=16 and x+y=-3, we can use the method of substitution or elimination. Let's use substitution:

From the second equation, we have x = -3-y. Now substitute this value for x in the first equation:

4(-3-y) - 3y = 16

-12 - 4y - 3y = 16

-7y = 28

y = -4

Substitute the value of y back into the second equation to find x:

x + (-4) = -3

x = -3 + 4

x = 1

Therefore, the solution to the linear equations is x = 1 and y = -4.

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

Step-by-step explanation:

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).

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.

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

Step-by-step explanation:

Recall to find the circumference of a circle the formula is [tex]C=\pi d[/tex] or [tex]C=2\pi r[/tex]. We will also need the formula for the area of a circle which is [tex]A=\pi r^{2}[/tex]. Since the area formula is in terms of r we will use the second formula for circumference.

We start by solving for r in the Circumference formula.

[tex]C=2\pi r\\\frac{C}{2\pi } =r[/tex]. We input this value of r into the area formula.

[tex]A=\pi r^{2} \\A=\pi (\frac{C}{2\pi })^2\\A=\pi (\frac{C^2}{4\pi ^2 })\\A=\frac{C^2}{4\pi ^2}[/tex]

The formula for the area of a circle in terms of its circumference is A = (C²) / (4π), by substituting the expression for the radius r = C / (2π) into the area formula A = πr².

The student has asked how to use the formula for the circumference of a circle to write a formula for the area of a circle in terms of its circumference. The formula for the circumference (C) of a circle is C = 2πr, where π (pi) is approximately 3.14159 and r is the radius of the circle.

To write the formula for the area (A) in terms of the circumference, we first solve the circumference formula for r: r = C / (2π). Then we substitute this expression for r into the formula for the area of a circle, which is A = πr². This gives us A = π (C / (2π))², simplifying, we get A = (C²) / (4π).

Thus, the formula for the area of a circle in terms of the circumference is A = (C²) / (4π).
