Figure Q has undergone a dilation
Which scale factor was used for the dilation?
A. 1/2
B. 3
C. 1/3
D. 2
Answers
Answer: 2
Step-by-step explanation: the figure has increased by 2 by x and y
Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.
An example of dilation math is a square of side 5 units can be dilated to a square of side 15 units, but the shape of the square remains the same.
Dimensions of Object Q are as follows:
(3 1/3,1)
(3 1/3,2)
(1,1)
(1,2)
Dimensions of Object Q’ are as follows:
(6 2/3,2)
(6 2/3,4)
(2,2)
(2,4)
Dimensions of Object Q to Object Q’ are as follows:
(3 1/3,1) ⇒ (6 2/3,2)
(3 1/3,2) ⇒ (6 2/3,4)
(1,1) ⇒ (2,2)
(1,2) ⇒ (2,4)
Let’s consider each vertex one by one.
Therefore, the scale factor in this dilation is 2.
So, the correct option is Option (D) 2

Answer:
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
m² + m⁵=m⁷
n⁵ + 0 = n⁵
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 bowling alley charges $75.00 to reserve the location, and then $8.00 per person. Which expression represents the total cost for any number of people n?
Answers
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.

You would earn $0.94 for recycling the tomato can.
I’m assuming you need to find the surface area first to get the total amount of square inches.
The area of the base is 12.56 square inches using the formula for area of a circle. Double it for both bases. 12.56 + 12.56 = 25.12 square inches.
Then the height times the circumference to get the square inches for the round side. 5.5 times 12.56 (which is the circumference and area of the base) equals 69.08 square inches.
And add 69.08 and 25.12 to get 94.2 square inches.
Now you get $0.01 for every full square inch, which would give you $0.94 for recycling the tomato can.

What is a triangle?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.

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.
What is an isosceles trapezoid?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.

1. Select all the equations that have no solution.
a. +6=5+
b. -2(−3)=-2+6
c. 4−4=3+2
d. 4(+1)=3(+2)
e. 5−3=-3+4
Answers
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.

If the regular price is $900 and the discount rate is 30%, what is the sale price?
Answers
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

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
