Oxygen has a boiling point of -183 and a melting point of -219 What is the temperature difference of the melting point and the boiling point?
Answers
Answer:
Difference = 36
Step-by-step explanation:
Given that,
The boiling point of Oxygen = -183
The melting point of Oxygen = -219
We need to find the temperature difference of the melting point and the boiling point.
Difference = boiling point - melting point
= -183-(-219)
= -183+219
= 36
Hence, the required temperature difference is 36.

Find the limit, if it exists.
Lim (2x^3+x^2+7)
X->2
Answers
Answer:
27
Step-by-step explanation:
In this case, because we have a polynomial where all x-values exist, we can plug the value (x=2) straight into the function:
[tex]\lim_{x \to \ 2} (2x^3+x^2+7)[/tex]
[tex]= 2(2)^3+(2)^2+7[/tex]
[tex]= 2(8)+4+7[/tex]
[tex]= 27[/tex]
The limit of (2x^3+x^2+7) as x approaches 2 equals 27, which makes sense since the value of (2x^3+x^2+7) at x = 2 is 27.

Since PR is an angle bisector then it divides the opposite side into segments which are proportional to the other 2 sides, that is
[tex]\frac{PQ}{PS}[/tex] = [tex]\frac{QR}{SR}[/tex] , substitute values
[tex]\frac{x+1}{16}[/tex] = [tex]\frac{x-2}{x+1}[/tex] ( cross- multiply )
(x + 1)(x + 1) = 16(x - 2) ← expand left side using FOIL
x² + 2x + 1 = 16x - 32 ( subtract 16x - 32 from both sides )
x² - 14x + 33 = 0 ← in standard form
(x - 3)(x - 11) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 11 = 0 ⇒ x = 11

Step 1: Define
5(x - 8) + 7 = 2
Step 2: Solve for x
Subtract 7 on both sides: 5(x - 8) = -5Divide 5 on both sides: x - 8 = -1Add 8 on both sides: x = 7Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 5(7 - 8) + 7 = 2(Parenthesis) Subtract: 5(-1) + 7 = 2Multiply: -5 + 7 = 2Add: 2 = 2Here we see that 2 does indeed equal 2.
∴ x = 7 is the solution to the equation.
An employee at a health club takes home an after-tax salary of $950 every two weeks. If the tax rate is 8%, how much does the employee make every two weeks before taxes? Round your answer to the nearest dollar.Write an equation and explain how you used it to find your answer.
Answers
Answer:
$1032.60
Step-by-step explanation:
Given data
salary = $950 every two weeks
tax rate = 8%
let the initial pay be x
and let the pay after tax deduction be p
p= x-8/100x
Hence the equation for his pay is
[tex]p=x-0.08x-------------1[/tex]
subsitute
950=x-0.08x
950= 0.92x
divide both sides by 0.92
x= 950/0.92
x=$1032.60
The employee make $1032.60 every two weeks before taxes
Of the following sets, which represents a function? (1 point)
Situation A = {student's name, all the colors that the student likes}
Situation B = {student's name, the student's favorite math teacher}
Group of answer choices
Both A and B
Only B
Neither A nor B
Only A
Answers
Answer: Only B
============================================
Explanation:
For situation A,
x is the input and it represents the student's name. y is the output and it represents the colors the student likes.The pairing (x,y) tells us what a certain student likes in terms of color.
For example, the point (Allen, Red) tells us that Allen likes the color red. We could also have (Allen, Green) telling us he also likes green. Because the input "Allen" maps to more than one output, this means situation A is not a function. A function is only possible if any given input maps to exactly to one output. The input must be in the domain. The domain in this case is the set of all students in the classroom.
In contrast, Situation B is a function because a student will only have one favorite math teacher. I'm interpreting this to mean "number one favorite" and not a situation where a student can select multiple favorites.

Kyle is making a quilt and he has determined he needs 497 square inches of gray fabric and 746 square inches of yellow. How many square yards of each material will he need? Round your answers up to the nearest quarter yard.
Answers
Answer:
0.38 yard² of gray material0.58 yard² of yellow.Step-by-step explanation:
1 yard is about 36 inches.
A square yard in square inches will therefore be:
= 36 * 36
= 1,296 inch²
He needs 497 square inches of gray fabric. In square yards that will be:
= 497/1,296
= 0.38 yard² of gray material
He needs 746 square inches of yellow:
= 746/1,296
= 0.58 yard² of yellow.
