Sergio has p paintings in his art collection. He and other local painting collectors agreed to donate a total of 48 paintings to the local museum. Each of the 12 collectors will donate the same number of paintings How many paintings will Sergio have in his art collection after his donation?
Step-by-step explanation:
The question is a bit confusing, so I am going to reword it to what I assume it means, which is, “Sergio initially has “p” paintings. There are 12 art collectors total, including Sergio. All the art collectors together donate a total of 48 paintings, and each art collector donates the same number of paintings. How many paintings does Sergio have left?”
p = number of Sergio’s paintings at the start.
p-X = the number of Sergio’s paintings at the end.
48 = the total number of paintings donated by all art collectors
12 = number of art collectors
48/12 = 4 = the number of paintings that each art collector donated
4 = X = the number of paintings that Sergio donated
p-4 = the number of paintings Sergio has left (answer)

What to do if the bases and exponents are different?
If the bases of two exponential expressions are different, they cannot be directly compared or combined.
THE BASE AND EXPONENTSYou 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).

How do you write 3 exponents?
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.

Analyze and Persevere Susan bought
3 plants that cost $2.75 each. She wants
to buy 3 clay pots that cost $4.15 each.
If Susan had $20 to start, does she have
enough money to also buy the clay pots?
Explain. Bc
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.

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.

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

Describe the triangle.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.

A triangle is a three-sided polygon. It is a geometric shape that has three edges and three vertices. Triangles can be classified based on their side lengths (such as equilateral, isosceles, or scalene) or based on the angles between their sides (such as acute, right, or obtuse). Triangles are a fundamental shape in geometry and are used in many branches of mathematics and physics. To form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
Using this rule, we can find the possible range of values for the third side of the triangle.
The least possible length of the third side would be:
