The chemistry teacher set out a 5 pound jar of salt at the beginning of the day. If each student needs 27.6 grams of salt for an experiment, how many students can perform the experiment before the jar is empty? (hint: 1lb=454grams)

Answers

Answer 1

Answer:

82 students

Step-by-step explanation:

In this, the first thing you should do is convert the five pounds to grams, which is 2270 grams. Now, all you need to divide 2270 by 27.6 to get the number of students because each student uses 27.6 grams and there 2270 grams being set each day. This gives you 82.2463768116 technically, but you should just round up, and that gives you 82 students. I hope this helped :D

Answer 2

Approximately 82 students can perform the experiment before the 5-pound jar of salt is empty.

In order to determine how many students can perform the experiment with the given jar of salt, we need to convert the jar's weight from pounds to grams, and then divide that by the amount of salt each student requires.

1. Given data: 1 pound = 454 grams (conversion factor).

2. The jar's weight is 5 pounds, so we multiply 5 by 454 to find the total grams of salt initially present in the jar:  

  5 pounds × 454 grams/pound = 2270 grams.

3. Each student needs 27.6 grams of salt for the experiment.

4. To find the number of students that can perform the experiment, we divide the total grams of salt by the grams per student:  

  Number of students = Total grams of salt / Grams per student.  

  Number of students = 2270 grams / 27.6 grams/student ≈ 82.42 students.

5. Since we can't have a fraction of a student, we round down to the nearest whole student (as we can't have a fraction of a student), yielding about 82 students.

6. However, we should also consider that after 82 students, there will be some salt left, but not enough for a complete experiment. Therefore, let's find out how much salt would be left after 82 students.

7. Salt used by 82 students = 82 students × 27.6 grams/student = 2263.2 grams.

8. Salt left in the jar = Total initial salt - Salt used by 82 students = 2270 grams - 2263.2 grams = 6.8 grams.

9. Since the remaining 6.8 grams is not sufficient for another complete experiment, we can conclude that approximately 82 students can perform the experiment before the jar is empty.

In conclusion, about 82 students can perform the experiment using the given 5-pound jar of salt.

how does (4x + 5)(3x + 10) demonstrate the closure property for polynomials?

Answers

Answer:

Step-by-step explanation:

A polynomial is a finite sum of terms in which all variables have whole number exponents and no variable appears in a denominator.

box4aa

box1

rembox22

The leading term in a polynomial is the term of highest degree.

The constant term in a polynomial is the term without a variable.

Polynomials: YES or NO

3x½

NO - exponent is not a whole number

polyd

NO - the variable is in the denominator

-3x2

YES - satisfies the polynomial definition

polyd1

NO - the square root of x can be written with a fractional exponent of x.

2x-3

NO - exponent is not a whole number.

Negative exponent places x3 in denominator.

polyrad3

YES - the exponent of x is 1 which is OK.

The coefficient being radical 3 is not a problem.

 

Classification by Terms

monomial

one term: 12, 4x, x2, -5xy

binomial

two terms: 2x - 1, x2 - 4

trinomial

three terms: x2 + 2x + 1

polynomial - one or more terms: polynomial means "many", but it can also be one term.

The ending of these words "nomial"

is Greek for "part".

Classification by Degree

Linear - degree of 1 or 0:    3x + 1  or  12

Quadratic - degree of 2:   2x2 - x + 7

Cubic - degree of 3:   3x3 + 4x2 + 3x + 5

definition The degree of a term with whole number exponents is the sum of the exponents of the variables, if there are variables. Non-zero constants have degree 0, and the term zero has no degree.  Example: 6x2 has a degree of 2;   4x2y3 has a degree of 5 (the sum of 2 and 3).

definition

The degree of a polynomial is the highest degree of its terms.

Example: 3x2 + 4x + 1 has a degree of 2;  x3 - x2 + 5x - 2 has a degree of 3

The standard form of a polynomial is when all like terms are combined and the degrees are arranged in descending order.

Polynomial: 2x + 3x5 + 4x3 - 8

Standard form: 3x5 + 4x3 + 2x - 8

3x5 + 4x3 + 2x1 - 8x0

boxdegree1

Will we ever really use the degree?

Knowing the "degree" of a polynomial function will let you determine the most number of solutions the function may have, and the most number of times the function will cross the x-axis.

FYI: The standard form of a polynomial is formally written as anxn + an - 1xn - 1 + ... + a2x2 + a1x + a0, where n is a non-negative integer, and a0, a1, a2, ..., an are real number constant coefficients with an ≠ 0.

bullet Polynomials and Closure:

Polynomials form a system similar to the system of integers, in that polynomials are closed under the operations of addition, subtraction, and multiplication.

CLOSURE: Polynomials will be closed under an operation if the operation produces another polynomial.

• Closure under Addition: (2x2 + 3x + 4) + (x2 - 5x - 3) = 3x2 - 2x + 1

When adding polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. This guarantees that the sum has variables and exponents which are already classified as belonging to polynomials. Polynomials are closed under addition.

• Closure under Subtraction: (2x2 + 3x + 4) - (x2 - 5x - 3) = x2 + 8x + 7

When subtracting polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. This guarantees that the difference has variables and exponents which are already classified as belonging to polynomials. Polynomials are closed under subtraction.

• Closure under Multiplication: (x + 1)(x2 + 4x + 3) = x3 + 5x2 + 7x + 3

When multiplying polynomials, the variables' exponents are added, according to the rules of exponents. Remember that the exponents in polynomials are whole numbers. The whole numbers are closed under addition, which guarantees that the new exponents will be whole numbers. Consequently, polynomials are closed under multiplication.

What about division?

Polynomials are NOT closed under division. Look at this simple counterexample:

closure1

When dividing variables with exponents, there is the possibility of creating a negative exponent. Negative exponents are not allowed in polynomials.

H=5c that the answer

Answer: c = 5h

Step-by-step explanation:

C is equal to the total cost, and h is equal to the number of hats bought.

c = 5h

What is Polygon?

Polygons are defined as plane (two-dimensional) and closed shapes that are formed by joining three or more line segments with each other.

"Polygon" consists of Poly meaning "many" and gon meaning "angle". We see many different polygons around us.

Regular vs Irregular Polygons

It is said that as per Euclidean Geometry, a polygon that is equiangular and equilateral is called a regular polygon while a polygon whose sides are not equiangular and equilateral is referred to as an irregular polygon. A regular polygon is always prefixed by the term "regular". Regular polygons are convex i.e., all the interior angles measure less than 180º.

In simple words, a regular polygon has all angles of the same measure at each vertex and all sides of the same length while a polygon that does not have sides of the same length and measurement of angles at each vertex different is referred to as an irregular polygon.

Given:

A three-dimensional figure with two parallel, congruent bases.

According to the polygon

A prism is a polyhedron that has two congruent and parallel faces (called the base and top), with all its remaining faces rectangles. This means that when a right prism is stood on its base, all the walls are vertical rectangles.
