Answer: For the GCF one, the GCF would be [tex]3y^{3}[/tex] because you are factoring from both [tex]15y^{4}[/tex] and [tex]12y^{3}[/tex], the reason it cannot be [tex]3y^{4}[/tex] is because that exponent value exceeds the exponent value of [tex]12y^{3}[/tex].

Step-by-step explanation:

So when you find a greatest common factor (GCF) you are basically trying to simplify the expression by extracting numbers to put it into its simplest form. The GCF of 15 and 12, is 3. And the GCF of the exponents would be [tex]y^{3}[/tex] .

25/2 is simplest form of fraction.

In math, what is a fraction?

An element of a whole is a fraction. In mathematics, the number is represented as a quotient, where the numerator and denominator are divided. Both are integers in a simple fraction.

                      Whether it is in the numerator or denominator, a complex fraction contains a fraction. The numerator and denominator of a correct fraction are opposite each other. The Latin word fraction, which meaning "to break," is where we get the English word fraction.

Using the Pythagorean theorem we know that (B) 20,21,29 can represent the length of sides of the right triangle.

According to the Pythagorean Theorem, the squares on the hypotenuse of a right triangle, or, in conventional algebraic notation, a2 + b2, are equal to the squares on the legs.

Now, calculate using the Pythagorean theorem as follows:

To write 3 exponents, you can use the following format: base^exponent.

An exponent is a small number that is written slightly above and to the right of a base number. The base is the number being multiplied, and the exponent tells you how many times the base is being multiplied by itself.

For example, to write 3 raised to the power of 2, you would write it as 3^2, which means 3 multiplied by itself 2 times, which is equal to 9.

It's important to note that the exponent is also known as the power, so 3^2, 3^3 and 3^4 are also read as 3 to the power of 2, 3 to the power of 3, 3 to the power of 4.

In summary, to write 3 exponents, you can use the format: base^exponent, where the base is the number being multiplied and the exponent tells you how many times the base is being multiplied by itself. In this case, 3^2, 3^3, and 3^4 represent 3 multiplied by itself 2, 3, and 4 times respectively.

The perimeter of triangle DEF is 10.8 units.

What is perimeter of triangle?

The area around any two-dimensional figure determines its perimeter. We can calculate the perimeter of any closed shape by adding the lengths of its sides.

We are given that triangle ABC is similar to triangle DEF

So,

⇒AB/DE = BC/EF = AC/DF

We are given AB=5, BC=6 and DE = 3

Therefore,

⇒AB/DE = BC/EF

⇒5/3 = 6/EF

⇒EF = 3.6

Similarly, we are given AC =7

So,

⇒AB/DE  = AC/DF

⇒5/3  = 7/DF

⇒DF = 4.2

Perimeter of triangle = DE + EF + DF

⇒Perimeter of triangle = 3 + 3.6 + 4.2

⇒Perimeter of triangle = 10.8 units

Hence, the perimeter of triangle DEF is 10.8 units.

Using arithmetic operations it can be seen that if Susan had $20 to start, she does not have enough money to buy 3 clay pots pricing $4.15 each after buying plants costing $2.75 each. She can buy 2 clay pots.

What are the types of arithmetic operation?

The four basic arithmetic operations in Maths, for all real numbers, are -

Addition (Finding the Sum; ‘+’)

Subtraction (Finding the difference;  ‘-’)

Multiplication (Finding the product; ‘×’ )

Division (Finding the quotient; ‘÷’)

Susan bought 3 plants that cost $2.75 each.

Using arithmetic operation of multiplication -

Total cost of the plants = number of plants bought × cost of each plant

Total cost of the plants = 3 × 2.75

Total cost of the plants = $8.25

Susan wants to buy 3 clay pots that cost $4.15 each.

Using arithmetic operation of multiplication -

Total cost of the clay pots = number of clay plots × cost of each clay pot

Total cost of the clay pots = 3 × 4.15

Total cost of the clay pots = $12.45

The total amount of money Susan has is $20.

She has already bought the plants.

So, the money left with her after buying the plants is -

Using arithmetic operation of subtraction -

Money left with Susan = Total money - Total cost of the plants

Money left with Susan = 20 - 8.25

Money left with Susan = $11.75

Therefore, Susan has enough money to buy only 2 clay pots and not 3.

Answer:

x = -2.65865384615

Step-by-step explanation:

-91x - 13x = 276.50

First, Combine Like Terms

-91x + (-13x) = -104x

-104x = 276.50

Second, divide

276.50 / -104 = x

x = -2.65865384615

Therefore , the ratio of the triangles ABC and XYZ's corresponding sides will therefore be the same.

A triangle is regarded as both a polygon since it has 4 elements or segments. It is a basic geometric form. Triangle ABC denotes a triangle having angles A, B, or C. Therefore, in Euclidean geometry, a single planes and square are produced whenever sides are not collinear. A triangle is a polygon if it has three parts and three corners. The points where a triangle's three sides come together are at its corners. The three triangular angles add up to 180 degrees.

Here,

An dilation is a change that produces an image that is smaller but still exactly the same shape also as original. A particular degree of stretching or contraction is possible for the initial figure.

We can see that in the problem, a 5x dilatation causes ABC to constrict to produce XYZ.

As a result, the triangles ABC or XYZ will have the same ratio of their corresponding sides.

A/B/C/D = A/C/X/Y/Z = 5

The ratio of the adjacent angles of the triangle ABC and XYZ will therefore be the same.

Graph B shows the position of Alec and Ardella after a run.

Translation is a type of transformation of geometrical figures. After translation, the original figure is shifted from a place to another place without affecting it's size.

Translation can be done upwards or downwards which changes the value of y. And if the translation is towards left or right, x coordinate changes.

Starting point of both Alec and Ardella = (2, 3)

Alec runs four units to the left and two units up.

(2, 3) becomes (2 - 4, 3 + 2) = (-2, 5)

Ardella runs four units to the left and seven units down.

(2, 3) becomes (2 - 4, 3 - 7) = (-2, -4)

The additive inverse of 4 /- 9 is 9 /- 4. This means that if you add 4 /- 9 and 9 /- 4 together, the result is 0.

The additive inverse of a number is the number that, when added to the original number, will result in a sum of 0. In other words, it is the opposite of the original number. For example, the additive inverse of 4 /- 9 is 9 /- 4. Adding 4 /- 9 and 9 /- 4 together will result in a sum of 0. This is because 4 /- 9 means -4 + 9 and 9 /- 4 means -9 + 4. When these two numbers are added together, the result is -4 + 4 which is 0. Additive inverses are often used in algebra and calculus to simplify equations and find solutions to problems. For example, if you have an equation with two unknowns and you know the value of one of the unknowns, you can use the additive inverse to find the value of the other unknown. This is because adding the two unknowns together will result in 0, and subtracting the known value from 0 will give you the value of the unknown.

Step-by-step explanation:

The illustration shows that (A) spring x has a higher elastic potential energy.

The energy that is stored when a force is used to deform an elastic object is known as elastic potential energy.

Until the force is released and the object springs back to its original shape, doing labor in the process, the energy is retained.

Kinetic energy is the power that an object has while in motion.

For instance, a stretched rubber band contains elastic potential energy because, when released, it will spring back to its resting position, converting the potential energy to kinetic energy.

So, according to the given image, spring x has more elastic potential energy.

If the bases of two exponential expressions are different, they cannot be directly compared or combined.

You can convert one of the bases to match the other by using logarithm properties. For example, if you want to compare or combine 2³ and 3², you can convert the base of one of them to match the other by using the logarithm property log3(3²) = 2, so 3² can be rewritten as 2^(log3(3²)) = 2².

If you want to add or subtract exponential expressions with different bases, you can convert one of the bases to match the other by using logarithm properties, then combine the exponents. For example, if you want to add 2³ and 3², you can convert the base of one of them to match the other by using the logarithm property log2(3) = 1.58496, so 3² can be rewritten as 2^(log2(3)*2) = 2^3.18992. Now you can add the two exponents: 2³ + 2^3.18992 = 2³ (1 + 2^0.18992).
