Triangles are similar if their angles are congruent, supported by the AAA theorem. The similarity of triangles implies that the corresponding side lengths are proportional, which can be expressed algebraically or in words.

To justify that the triangles are similar, we look for congruent angles and proportional sides. The student indicated that the triangles have the same angles, which satisfies the AAA (Angle-Angle-Angle) similarity theorem. Because the angles are congruent, the sides are proportional, which means the ratios of corresponding sides are equal.

With words, we can express the relationship of corresponding lengths in similar triangles as the ratio of one triangle's side lengths to the other's. Algebraically, if we have corresponding sides a, b, and c from Triangle 1, and sides d, e, and f from Triangle 2, then a/d = b/e = c/f.

To solve for an unknown quantity, we algebraically isolate the variable in our equation, plug in the known values, calculate the answer, and then check to ensure the result is reasonable. For example, if we know sides a, b, d, and e, and we want to find side c, we would set up the proportion c/f = a/d, and after substituting the known values, we solve for c.

The unit of measure that is more accurate for measuring the height of a door in feet and inches is inches.

The unit of measure that is more accurate for measuring the height of a door in feet and inches would be inches. This is because inches provide a smaller unit of measurement, allowing for more precise measurements. To convert the height of a door from feet and inches to inches, you can multiply the number of feet by 12 and add the number of inches. For example, if a door is 6 feet 2 inches tall, you would multiply 6 by 12 to get 72 inches, and then add 2 inches to get a total height of 74 inches.

# Write down the decimal divided by 1

# Multiply both top and bottom by 10 for every number right the

  decimal point

# Simplify (or reduce) the fraction

* Lets solve the problem

- A stock market index drops by 1.38 points

- We need to find the rational number represents the change in

 the index

∵ Drop means the stock is become less

∴ The value of change will be negative

∵ The stock is drops by 1.38

∴ -1.38 = -1.38/1

- Multiply up and down by 100 because there are 2 digits right the

 decimal point

∴ -1.38 = -138/100

- Divide up and down by 2

∴ -1.38 = - 69/50

∴ The change in the index is - 69/50 (-1.38)

To find the cost of a single cinema ticket, multiply the amount each friend paid, £6.15, by 4 to get the total cost for 3 paid tickets. Divide this total, £24.60, by 3 to find that the cost of one ticket is £8.20.

The question pertains to a group of 4 friends who buy cinema tickets using an offer where they buy 3 tickets and get 1 free. Since each friend pays £6.15, we need to determine the actual cost of a single ticket.

Under the offer, they are buying a total of 4 tickets for the price of 3. Therefore, we can calculate the cost of 3 tickets by multiplying £6.15 by 4, which gives us a total of £24.60. To find the cost of a single ticket, we divide the total cost of £24.60 by the number of tickets bought, which is 3.

Here is the calculation step:
Total cost for 4 friends = 4 × £6.15 = £24.60
Cost of a single ticket = [tex]\frac{24.60}{3}[/tex] tickets = £8.20

Therefore, the cost of one ticket without the offer is £8.20.

Bob has 1 more marble than Kayla, calculated by subtracting Kayla's marble count from Bob's.

To determine how many more marbles Bob has than Kayla, we can subtract Kayla's number of marbles from Bob's. The calculation is straightforward: [tex]\(6 - 5 = 1\)[/tex]. Therefore, Bob has 1 more marble than Kayla.

In a visual representation of their marbles, Bob has 6 marbles, Malik has 3 marbles, and Kayla has 5 marbles. To find the difference between Bob and Kayla, we subtract Kayla's count from Bob's. The result, 1, indicates the additional marble Bob possesses compared to Kayla.

This is a simple arithmetic operation that reflects the concept of finding the difference between two quantities. In this case, the subtraction represents the surplus marbles that Bob has in comparison to Kayla. The positive result suggests that Bob has an extra marble beyond what Kayla possesses.

In summary, Bob has 1 more marble than Kayla, as determined by subtracting Kayla's marble count from Bob's. This simple arithmetic operation provides a clear understanding of the numerical difference in their marble quantities.

Final answer:

The angle of rotation for rotational symmetry of a regular pentagon is 72°, which is found by dividing the full rotation of 360° by the number of sides (5).

Explanation:

The angle of rotation for rotational symmetry of a regular pentagon is the angle you rotate the pentagon until it looks exactly the same as it did before the rotation. A regular pentagon has five sides that are all of equal length, and the amount of rotation required to bring one vertex to the position of the next is 360° divided by the number of sides. Therefore, the angle of rotation for a regular pentagon is 360°/5, which equals 72°.

Answer:

-5 7/8 ft (Answer D)

Step-by-step explanation:

Note that 5.875 ft is the same as 5 7/8 ft.

The diver is initially 5 7/8 ft beneath the water surface, so we give that 5 7/8 ft the negative sign:

-5 7/8 ft represents the diver's position in relation to the surface.

The driver's position in relation to the surface before swimming to the top is represented by D. -5 7/8 feet. This is because in this scenario, a negative number signifies underwater depth.

In mathematics, the term 'relation' is often used in the context of functions and refers to the way two sets of numbers are interconnected. In your scenario, a negative number is used to signify the driver's position underwater, while a positive number indicates their position above water. Therefore, if the diver swims 5.875 feet up to the surface, this would mean their original position was -5.875 feet. When expressed in decimal form, this would be -5.9, and when expressed in fractions, it would be -5 7/8 feet. Hence, the correct answer would be D. -5 7/8 feet.

C=78

Step-by-step explanation:

A= a and 102 are on a straight line so they add up to 180. 180-102=78. The same goes for C

B= the vertical angle for 102, or the same thing with a and c, just flipped around

3x+8+4x=-8(x-6)-8(13x+5)​

Get rid of parenthesis.

The value of x for the given rectangles is 15.

When two figures in mathematics have the same shape but different sizes, those two figures are referred to as comparable figures. For instance, similar objects are seen in different-sized images of a person, such as a passport size, stamp size, etc., but they are not consistent. Two comparable shapes in geometry are those whose dimensions are equivalent or have a shared ratio but the width or length of their sides differ. Examples include similar triangles, similar rectangles, and similar squares.

Given two rectangles are similar,

so the ratio of their lengths is equal, according to similar figure property,

given dimensions of rectangle 1 is  14 and 10

dimensions of rectangle 2 ia 21 and x

so 14/21 = 10/x

x = 21 x 10/14

x = 15

Hence value of x is 15.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Because a square has equal lengths on a side so finding the area of the square would just be the number on one side multiplied by itself so they decided to call it four squared.

The term 'four squared' refers to the mathematical expression 42, which represents the number four multiplied by itself resulting in 16. It also reflects the area of a square with side lengths of four units, illustrating the foundational concept of squaring numbers in geometry and algebra.

The term 'four squared' refers to the mathematical expression 42, which equals 16. This expression is the result of multiplying the number four by itself. In mathematics, squaring a number represents the area of a square with sides of that specific length. For example, a square with sides of 4 units has an area of 16 square units because the length of one side (4) is multiplied by the width, which is also 4 (since all sides of a square are equal). Hence, four squared (4 x 4) equals 16.

Another representation of this concept comes from geometry and the visualization of physical space. A square with a side length of 2 units, for instance, has an area of 22 or 4 square units because it has four equal divisions, each 1 unit by 1 unit. So when we talk about 'four squared', we're discussing an area that's four times larger than the original 2 x 2 square.

The concept of numbers being squared is foundational to algebra and geometry. The phrase 'four squared' is an embedded term in mathematics that signifies the squaring operation, which is critical for finding areas of squares and also is applied in various mathematical laws and properties, such as the Pythagorean theorem.

Possibly 17 and 22.

Step-by-step explanation:

17 plus 22 equals to 39.

22 is five more than 17.

The two numbers are 17 and 22 whose sum is 39.

A numerical expression is in form of numbers and variables separated by the operation of addition and subtraction.

Given that the sum of two numbers is 39.

Also given that the larger number is 5 more than the smaller number.

Assuming the smaller number to be 'n'.

∴ The larger no. is (x+5).

So, the given statement can be written as,

x + (x+5) = 39.

2x + 5 = 39.

2x = 39 - 5.

2x = 34.

x = 34/2.

x = 17.
