Answer:

158 1/3

Step-by-step explanation:

Create an equation. J = JACK and S = SALLY

2s+25 = Jack

Jack + Sally = 225

2s+25+s = 225

3s+25 = 225

3s = 200

s = 66 2/3

66 2/3*2 = 133 1/3

133 1/3 + 25 = 158 1/3

Jack's weight if together they weigh 225 pounds will be 158(¹/₃).

<h3>
What is an expression?</h3>

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Jack's weight is 25 pounds more than twice Sally's weight and the total weight is 225 pounds.

Create an equation. J = JACK and S = SALLY

2s+25 = Jack

Jack + Sally = 225

2s+25+s = 225

3s+25 = 225

3s = 200

s = 66(²/₃)

66(²/₃) x 2 = 133( ¹/₃)

133( ¹/₃) + 25 = 158( ¹/₃)

Therefore, Jack's weight if together they weigh 225 pounds will be 158(¹/₃).

Classify the polynomial according to its degree and number of terms 3x^2+8x​
Sunny_sXe [5.5K]

Answer:

Classifying Polynomials

Polynomials can be classified two different ways - by the number of terms and by their degree.

1. Number of terms.

A monomial has just one term. For example, 4x2 .Remember that a term contains both the variable(s) and its coefficient (the number in front of it.) So the is just one term.

A binomial has two terms. For example: 5x2 -4x

A trinomial has three terms. For example: 3y2+5y-2

Any polynomial with four or more terms is just called a polynomial. For example: 2y5+ 7y3- 5y2+9y-2

Practice classifying these polynomials by the number of terms:

1. 5y

2. 3x2-3x+1

3. 5y-10

4. 8xy

5. 3x4+x2-5x+9

Answers: 1) Monomial 2) Trinomial 3) Binomial 4) Monomial 5) Polynomial

2. Degree. The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).

Examples:

5x2-2x+1 The highest exponent is the 2 so this is a 2nd degree trinomial.

3x4+4x2The highest exponent is the 4 so this is a 4th degree binomial.

8x-1 While it appears there is no exponent, the x has an understood exponent of 1; therefore, this is a 1st degree binomial.

5 There is no variable at all. Therefore, this is a 0 degree monomial. It is 0 degree because x0=1. So technically, 5 could be written as 5x0.

3x2y5 Since both variables are part of the same term, we must add their exponents together to determine the degree. 2+5=7 so this is a 7th degree monomial.

Classify these polynomials by their degree.

1.7x3+52+1

2.6y5+9y2-3y+8

3.8x-4

4.9x2y+3

5.12x2

Answers 1) 3rd degree 2) 5th degree 3) 1st degree 4) 3rd degree 5) 2nd degree

The volume of this cylinder is 1,909.92384 cubic millimeters. What is the radius? Use n=3.14 and round your answer to the neares
klemol [59]

Remember that the volume of a cylinder is

\begin{gathered} V=\pi\cdot r^2\cdot h \\  \end{gathered}

so we have that

r=\sqrt[]{\frac{V}{\pi\cdot h}}=\sqrt[]{\frac{1909.92384}{3.14\cdot6.6}}=\sqrt[]{92.12}=9.6

so the radius is 9.6 milimeters

Mrs. Flores asked her students to write a number, its opposite, and its absolute value, in that order. Four of her students turn
oee [108]

Answer:

Sarah is correct

Step-by-step explanation:

Required

Which of the students is correct

Let a number be x,

Given what the teacher asked the students to do, the solution is:

Number = x

Opposite = -x

Absolute = |x|

Only Sarah got this correctly; others are incorrect.

The proof is as follows.

For Sarah

Number = 1416

Opposite = -1416

Absolute =|1416| = 1416

So, the numbers will be: 1416, -1416 and 1416

<em>Other students are incorrect</em>
