Answer:

75+8n

Step-by-step explanation:

$75 is the constant because that is the amount of money only paid once. $8 is the coefficient because it is multipled by the variable n. The variable is the amount of people going to the bowling alley.

Therefore, to determine the total cost, you need add $75 to the product of 8 and the number of people coming.

Answer:

l = 14

Step-by-step explanation:

The perimeter of a rectangle is

P =2(l+w)

The width is x-6

w = x-6

The length is 8 units longer than the width

l = w+8

l = x-6+8

l = x+2

We can substitute this into the equation for Perimeter, which is given as 40

40 = 2(x+2 + x-6)

Combine like terms

40 =2 (2x-4)

Divide by 2

40/2 = 2/2 (2x-4)

20 = 2x-4

Add 4 to each side

20+4 =2x-4+4

24 = 2x

Divide by 2

24/2 =2x/2

12=x

We want to know the length

l = x+2

l =12+2

l = 14

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Multiply the length that you have been given by 2

2: Then, subtract the result from the perimeter.

3: You now have the total length for the remaining 2 sides.

4: Width or height is the number divided by 2.

Answer:

a, and e.

Step-by-step explanation:

x+6=5+x has no solution. When you subtract 6 from both sides, you get x=-1+x. We know that x doesn't equal -1+x, so this equation has no solution.

-2(x-3)=-2x+6 has a solution. When you distribute, you get -2x+6=-2x+6.

4-4x=3x+2 has a solution. Subtract 4 from both sides to get -4x=3x-2. Subtract 3x from both sides to get -7x=-2, then divide -2 by -7 to get x=0.285714285714. This equation has a solution.

4(x+1)=3(x+2) has a solution. Distribute to get 4x+4=3x+6. Subtract 4 from both sides to get 4x=3x+2. Subtract 3x from both sides to get x=2. This equation has a solution.

5-3x=-3x+4 has no solution. Subtract 5 from both sides to get -3x=-3x-1. We know that -3x does not equal -3x-1, so we can determine that this equation has no solution.

Answer:

a  and e has no solution

Step-by-step explanation:

A) x + 6 = x +5

Subtract x from both sides

   x + 6 - x = x + 5 - x

        6 = 5 which is not true.

So, this equation has no solution

d) 5 - 3x = -3x + 4

Add 3x to both sides

5- 3x + 3x = -3x + 4 + 3x

5 = 4         which is not true.

So, no solution

28m⁷n⁵

Step-by-step explanation:

You would first multiply 14 by 2. You would then multiply (which is really addition when it comes to exponents) your like-term exponents.

(14m²n⁵)(2m⁵) =28m⁷n⁵

14(2) = 28

Answer:

[tex]28 {m}^{7} {n}^{5} [/tex]

Step-by-step explanation:

14*2=28; m^2*m^5=m^7.

When you're working with multiplication of powers, you have to add the exponents. For example

[tex] {x}^{4} \times {x}^{2} = {x}^{6} [/tex]

Because

[tex] {x}^{4} = x \times x \times x \times x \\ {x}^{2} = x \times x \\ {x}^{4} \times {x}^{2} = x \times x \times x \times x \times x \times x = {x}^{6} [/tex]

The probability that it will be watermelon flavored is -

P{E} = 1/5.

Given is a bag of jellybeans has 20 watermelons jellybeans, 45 sour apple jellybeans, 30 orange jellybeans and 5 cotton candy jellybeans.

We can write the probability as -

P{E} = (20)/(20 + 45 + 30 + 5)

P{E} = 20/100

P{E} = 1/5

Therefore, the probability that it will be watermelon flavored is -

P{E} = 1/5.

Answer:

Intersect/Solution at (1, -2)

Step-by-step explanation:

Equation 1: y = 3x - 5

Equation 2: y = 6x - 8

Step 1 Mutliply each side of equations one by -2

New Equation 1: -2y = -6x + 10

New Equation 2: y = 6x -8

Add the Equations: -y = +2

Multiply each side by -1 and you'll get that y = -2

Plug in -2 to either equation: -2 = 3x - 5

add 2 to each side 0 = 3x -3

add 3 to each side 3x = 3

divide by 3 and you'll get that x = 1

Part A:The solution of the pair of  the equation is,x=1 and y=- -2.

Part B:  If the two equations are graphed, at point (1,-2) will the lines representing the two equations intersect.

If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:

y = mx +c

A pair of equations is shown below:

y = 3x − 5 -------1

y = 6x − 8 --------2

Substitute the value of y from the equation 1 into equation 2;

3x − 5=6x − 8

3x=-5+8

3x=3

x=1

Put the value of x in the equation 1;

y = 3x − 5 -------1

y=3(1)-5

y=- -2

Hence,the solution of the pair of  the equation is,x=1 and y=- -2 and at point (1,-2) will the lines representing the two equations intersect.

Here is an example of how to draw an isosceles trapezoid:

   _______

 /                 \

/_________\

In this trapezoid, the two parallel sides (the top and bottom sides) are of equal length, and the two non-parallel sides (the left and right sides) are also of equal length. The angles between the top and left sides and between the top and right sides are equal, as are the angles between the bottom and left sides and between the bottom and right sides.

An isosceles trapezoid is a type of trapezoid where the two non-parallel sides of the trapezoid are of equal length. This means that the trapezoid has a line of symmetry through its mid-point, which divides the trapezoid into two congruent triangles. The two parallel sides of an isosceles trapezoid are also referred to as bases, and the height of the trapezoid is the perpendicular distance between the two bases.

Because an isosceles trapezoid has two congruent triangles, the angles opposite these sides are also congruent. Therefore, an isosceles trapezoid has two pairs of congruent angles, with each pair containing one acute angle and one obtuse angle. The acute angles are located adjacent to the parallel sides, while the obtuse angles are located adjacent to the non-parallel sides.

Isosceles trapezoids have several interesting properties, including that the diagonals of an isosceles trapezoid are congruent, and that the diagonals bisect each other. Additionally, the length of each diagonal can be found using the Pythagorean theorem, and the area of an isosceles trapezoid can be determined using the formula:

Area = ((a + b) / 2) * h

Where "a" and "b" are the lengths of the two parallel sides (bases) and "h" is the height of the trapezoid.

PART B:

An isosceles trapezoid is a quadrilateral with two parallel sides (the bases) and two non-parallel sides of equal length. A parallelogram is also a quadrilateral with two pairs of parallel sides.

An isosceles trapezoid can be thought of as a special case of a parallelogram where one pair of opposite sides is shorter than the other pair. In fact, if you extend the non-parallel sides of an isosceles trapezoid until they intersect, you will get a parallelogram with the same base and height as the original trapezoid.

Conversely, if you take a parallelogram and draw a line segment parallel to one pair of opposite sides, you will get an isosceles trapezoid. This means that every isosceles trapezoid can be thought of as a parallelogram with a missing piece, and every parallelogram can be thought of as an isosceles trapezoid with extra pieces added on.

So, in summary, isosceles trapezoids and parallelograms are related in that isosceles trapezoids can be thought of as special cases of parallelograms, and parallelograms can be thought of as isosceles trapezoids with extra pieces added on.

PART C:

No, we cannot use the term "isosceles" to describe a rectangle because a rectangle, by definition, has four right angles and opposite sides that are parallel and congruent to each other. An isosceles trapezoid, on the other hand, has only one pair of parallel sides and two non-parallel sides that are congruent to each other.

The term "isosceles" is typically used to describe triangles or trapezoids where two sides are congruent to each other. In an isosceles triangle, two sides are equal in length, while in an isosceles trapezoid, two non-parallel sides are equal in length. However, in a rectangle, all four sides are equal in length, not just two.

Therefore, while we can describe a rectangle as having all sides congruent to each other, we cannot describe it as an isosceles rectangle because "isosceles" implies only two sides are congruent, which is not the case for a rectangle.

Step-by-step explanation:

The table is completed below.

We can say that the relationship between the scale factor and the area of scaled copies is proportional.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

Using the formula for the area of a triangle:

Area = 1/2 x base x height

With a base of 3cm and height of 2cm, the area of the original triangle is:

Area = 1/2 x 3cm x 2cm = 3cm²

To find the area of the scaled triangles, we can use the scale factor to determine the corresponding dimensions, and then calculate the area using the same formula.

Scale factor Corresponding dimensions Area

1                         3cm x 2cm               3cm²

2                         6cm x 4cm                12cm²

5                        15cm x 10cm               75cm²

s                        3s cm x 2s cm             3s² cm²

Now,

To see if the relationship between the scale factor and the area of scaled copies is proportional, we can calculate the ratio of the area to the scale factor for each row of the table:

Scale factor Corresponding dimensions Area Ratio of area to scale factor

1                             3cm x 2cm             3cm²          3/1 = 3

2                             6cm x 4cm             12cm² 12/2 = 6

5                                 15cm x 10cm      75cm² 75/5 = 15

s                            3s cm x 2s cm     3s² cm²  (3s²)/s = 3s

In each case, the ratio of the area to the scale factor is constant, which means that the relationship between the scale factor and the area of scaled copies is indeed proportional.

Therefore,

We can say that the relationship between the scale factor and the area of scaled copies is proportional.

Answer:

$630

Step-by-step explanation:

First, multiply the original price by the decimal of the percentage:

900 x 0.30 = 270

Since this is a discount we subtract the original amount and the discount amount. If it we were calculating tax or a raised price, you would add. But were lowering the price so:

900 - 270 = 630

Therefore, it’s 630
