Maria draws △PQR. Then she applies a dilation with scale factor 14 and center of dilation P to the triangle. Next, she translates the image 2 centimeters up and 3 centimeters right. She labels the final image as △XYZ.
Which of the following must be true about △PQR and △XYZ?
△PQR and △XYZ are similar but not congruent.
△PQR and △XYZ are congruent but not similar.
△PQR and △XYZ are neither similar nor congruent.
△PQR and △XYZ are congruent and similar.
Answers
Answer:
△PQR and △XYZ are similar but not congruent.
Step-by-step explanation:
When Maria dilated the triangle the size changed and so they can't be congruent. But it wouldn't have changed it's shape, so it'll be similar.
Answer: △PQR and △XYZ are similar but not congruent.

The distance light travels in one year is known as a light-year. A light-year is equal to 5.87 × 1012 miles. The closest Earth ever gets to Jupiter is 3.65 × 108 miles. What is a correct representation of the number of years it will take light to travel from Earth to Jupiter at this distance? Check all that apply.
Answers
Answer:
The answer is A and C
Step-by-step explanation:
The required distance is 6.21 × 10⁻⁵ light-years it will take light to travel from Earth to Jupiter at this distance. which is the correct answer would be an option (C)
What is the distance?Distance is defined as the product of speed and time.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
We have been given that the distance light travels in one year is known as a light year.
one light-year = 5.87 × 10¹² miles.
A light year is the length of time it takes light to travel one distance.
Since the closest that Earth ever gets to Jupiter is 3.65 × 10⁸ miles.
So 3.65 × 10⁸ miles = 1/(5.87 × 10¹² )×(3.65 × 10⁸) light years
⇒ 6.21 × 10⁻⁵ light years
Therefore, the required distance is 6.21 × 10⁻⁵ light-years it will take light to travel from Earth to Jupiter at this distance.

(keep in mid it's either an infinite solution, 0, or 1)
Answers
Answer:
0 solutions
Step-by-step explanation:
2n + 4 = 4n + 1 - 2n
↑
first combine like terms (right side)
2n + 4 = 2n + 1
but this part you can tell that there's 0 solutions, because both sides have 2n/ same variable with same number.
No Solution.
Once you combine the like terms 4n-2n of the second equation you end up with
2n+4 = 2n+1.
There is no value of n that results in a true equation.
How do the angle measures and side lengths compare in similar figures ?
Answers
Answer:
Matching sides of two or more polygons are called corresponding sides, and matching angles are called corresponding angles. If two figures are similar, then the measures of the corresponding angles are equal and the ratios of the lengths of the corresponding sides are proportional.
Step-by-step explanation:
The angles are congruent in a similar figure and the ratio of the sides is in proportion.
What are similar figures?Two figures are said to be similar if they are the same shape. In more mathematical language, two figures are similar if their corresponding angles are congruent, and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor.
Given: Two figures are similar for example say two triangles are similar then Similar triangles are triangles that have the same shape, but their sizes may vary. All equilateral triangles, squares of any side lengths are examples of similar objects. In other words, if two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion. We denote the similarity of triangles here by ‘~’ symbol.
Hence, The angles are congruent in a similar figure and the ratio of the sides is in proportion.

7x7=49
8x8=64
9x9=81
10x10=100
11x11=121
12x12=144
Janine can build 12 models of equal dimension (1x1), (2x2), (3x3), (4x4), (5x5), (6x6), (7x7), (8x8), (9x9), (10x10), (11x11), (12x12).
What is a cube?A three-dimensional object with six equal square faces is called a cube. The cube's six square faces all have the same dimensions.
A cube is become by joining six squares such that the angle between any two adjacent lines should be 90 degrees.
The surface area of the cube = 6 side².
The volume of the cube = side³.
Given that Janine can build up to 150 inches² area of cube.
Area of cube < 150
So,
13x13 = 169 > 150 And 12x12 = 144 < 150
So Janine can use up to 12 inches cube
Possible dimensions up to 12 inches are
(1x1), (2x2), (3x3), (4x4), (5x5), (6x6), (7x7), (8x8), (9x9), (10x10), (11x11), (12x12).

A-Real, Rational, integer
B-Real, Rational
C-Irrational, Integer

Please Help Me ; ^;
Answers
Answer: Real, irrational
Step-by-step explanation:
Real because it is an actual measurement. Irrational because π can't be expressed as a fraction. Not an integer because integers are whole numbers.
The correct classification is -Real, Irrational
What is irrational number?Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction, p/q where p and q are integers. The denominator q is not equal to zero (q ≠ 0). Also, the decimal expansion of an irrational number is neither terminating nor repeating.
Irrational numbers are real numbers that cannot be represented as a simple fraction. These cannot be expressed in the form of ratio, such as p/q, where p and q are integers, q≠0. It is a contradiction of rational numbers.
Given number: 7* pi
Here, 7 is the real number.
But pi is real but not rational number.
pi is an irrational number.
