Jenna can paint the shed in 2 hours. Juan can paint it in 1.5 hours. • Jenna says is they work together the job will take 1/2+1/1.5=1^1/2 hours. • Juan says if they work together the job will take 2+1.5/2=1^3/4 hours. Determine if either Jenna or Juan is correct. Explain your reasoning with numbers and words.
Answer:
There is a formula for this:
[Worker 1 Time * Worker 2 Time] / [Worker 1 Time + Worker 2 Time]
[2 * 1.5] / [2 + 1.5] = 3.0 / 3.5
= 0.8571428571 Hours =
51.43 minutes
Both Jenna and Juan are INCORRECT.
Step-by-step explanation:
Answer:
Step-by-step explanation:
1 job / 2 hours + 1 job / 1.5 hours = 1 job / x When they work together.
1/2 + 1/1.5 = 1/x Basic Equation. Change to decimal form
0.5 + 0.6666 = 1/x Add like terms on the left
1.1666666 = 1/x Multiply by x on both sides.
1.1666667 x = 1 Divide by 1.16666667
x = 1 / 1.166667 Do the division.
x = 0.8571428
x = 6/7 of an hour.
This kind of question will always produce an answer that is less than the smallest number.

Which statement about rhombuses and parallelograms is true?
A) Rhombuses ALWAYS have four equal sides; parallelograms sometimes do not.
B) Rhombuses ALWAYS have four right angles; parallelograms sometimes do not.
C) Parallelograms ALWAYS have opposite sides equal; rhombuses sometimes do not.
D) Parallelograms ALWAYS have opposite sides parallel; rhombuses sometimes do not.
The correct statement about rhombuses and parallelograms is that rhombuses always have four equal sides while parallelograms sometimes do not. The other options are not true for rhombuses and parallelograms.
Explanation:The correct statement about rhombuses and parallelograms is option A) Rhombuses ALWAYS have four equal sides; parallelograms sometimes do not. A rhombus, by definition, is a four-sided figure with all sides having equal length while a parallelogram is a four-sided figure with only opposite sides being equal.
Options B, C, and D are incorrect. Rhombuses do not always have four right angles; that is characteristic of a rectangle. Parallelograms always have opposite sides equal and parallel, so C and D are not true.

The correct answer is option (A).The true statement is that rhombuses always have four equal sides, while parallelograms sometimes do not. This characteristic is a key distinction between rhombuses and general parallelograms. The other statements about angles and sides are incorrect regarding rhombuses and parallelograms.
To determine which statement about rhombuses and parallelograms is true, we need to understand their definitions and properties:
Parallelogram: A quadrilateral with opposite sides that are both parallel and equal in length. Opposite angles are equal, and adjacent angles are supplementary.Rhombus: A type of parallelogram where all four sides are of equal length. Additionally, the diagonals of a rhombus are perpendicular and bisect each other at right angles.Given these definitions, let's evaluate each statement:
A) Rhombuses ALWAYS have four equal sides; parallelograms sometimes do not.Option A) is the true statement as rhombuses always have four equal sides and parallelograms sometimes do not.

Answer:
80.73 each month
Step-by-step explanation:
The original price of the computer is $598. It is offered for 25% off. This means you pay 75% of the original price or 0.75(598) = 448.5. The sales price is $448.50. You will pay 8% tax on this price. This means you'll pay 100% of the price plus 8% more. So this is 1.08(448.5) = 484.38.
In total you pay 484.38 over 6 months. This means each month you pay 484.38/6 = 80.73.

what is the horizontal asymptote of the function f(x)= -2x/x+1
Answer:
-2
Step-by-step explanation:
We have been given a function f(x)=\frac{-2x}{x+1} and we are asked to find the horizontal asymptote of our given function.
Recalling the rules for a horizontal asymptote:
1. If the numerator and denominator have equal degree, the horizontal asymptote will be the ratio of the leading coefficients.
2. If the polynomial of denominator has larger degree than the numerator, then the horizontal asymptote will be the x-axis or y=0.
3. If the polynomial of numerator has larger degree than denominator, then the function has no horizontal asymptote.
Here, the numerator and denominator are of the same degree. So the horizontal asymptote will be the ratio of the coefficients.
Horizontal asymptote = [tex]-\frac{2}{1}[/tex] = -2

What is the domain of the function y= sqrt3/x ? plese help
Answer:
all reals, except at x=0
Step-by-step explanation:
because x is in the denominator, x cannot equal 0
For this case we have a function of the form [tex]y = f (x),[/tex]where:
[tex]f (x) = \sqrt {\frac {3} {x}}[/tex]
we must find the domain of the function.
The domain is given by all the values for which the function is defined.
Note that "x" is not defined for negative numbers or for zero. Then x can only take strict higher values to zero.
Domain: {x | x> 0}
Answer:
Domain: {x | x> 0}
Lynn is a single mother with two children. She qualifies to file as head of household. Her total income before deductions was $38,900 last year. Her total deductions were $11,450. Her employer withheld $3,150 from her pay for tax. Use the tax table below. How much more will Lynn owe in taxes?
To calculate how much more Lynn owes in taxes, we need to subtract her deductions from her total income to find her taxable income, then apply the tax rate from the provided table (which is missing in this case) to determine her tax liability. Unfortunately, without the tax table, we cannot accurately compute her tax obligation or the additional amount owed beyond the $3,150 withheld.
Explanation:The question involves calculating how much more in taxes Lynn will owe after her deductions. Lynn's total income before deductions is $38,900. After subtracting her total deductions of $11,450, her taxable income becomes $27,450. Without the tax table provided in the question, we cannot determine the exact tax rate applicable to Lynn's taxable income nor can we calculate the precise amount of taxes she owes or how much more she will have to pay on top of the $3,150 already withheld by her employer. Typically, to find out how much more Lynn owes, we would apply the appropriate tax rate to her taxable income and then subtract the amount already withheld.
Without specific tax rates and brackets from the tax table, we can only outline the steps to calculate Lynn's tax liability. This scenario underlines the importance of having complete information to accurately determine tax obligations.
The amount Lynn owe in taxes is determined as $399. (Option D).
How to calculate the amount Lynn owe in taxes?
The amount Lynn owe in taxes is calculated by applying the following method as shown below.
Lynn income before tax = $38,900
the total deduction in Lynn income = $11,450
amount withheld for taxes = $3,150
Lynn total income after tax is calculated as;
total income after tax = $38,900 - $11,450
total income after tax = $27,450
From the tax table attached, the tax payable for a head of household earing an income between $27,450 and $27,500 is $3,549.
So if the employer withheld $3,150 for tax, the remaining amount to be paid for tax is;
remaining amount for be paid for tax is calculated as;
= total tax - amount withheld
= $3,549 - $3,150
= $399
Thus, the amount Lynn owe in taxes is $399.
The complete question is below:
Lynn is a single mother with two children. She qualifies to file as head of household. Her total income before deductions was $38,900 last year. Her total deductions were $11,450. Her employer withheld $3,150 from her pay for tax. Use the tax table below. How much more will Lynn owe in taxes?

Answer:
{y,x} = {-6,-2}
Step-by-step explanation:
/ Solve equation [2] for the variable y
[2] y = 2x - 2
// Plug this in for variable y in equation [1]
[1] (2x-2) - x = -4
[1] x = -2
// Solve equation [1] for the variable x
[1] x = - 2
// By now we know this much :
y = 2x-2
x = -2
// Use the x value to solve for y
y = 2(-2)-2 = -6

Helaine graphed the equation 12x – 4y = 3. What was the slope of Helaine’s line?\
Answer:
[tex]\large\boxed{\text{The slope}\ m=3}[/tex]
Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
We have the equation of a line in the standard form:
[tex]12x-4y=3[/tex]
Convert to the slope-intercept form:
[tex]12x-4y=3[/tex] subtract 12x from both sides
[tex]-4y=-12x+3[/tex] divide both sides by (-4)
[tex]y=\dfrac{-12}{-4}x+\dfrac{3}{-4}\\\\y=3x-\dfrac{3}{4}[/tex]
Answer: The required slope of the given line is 3.
Step-by-step explanation: Given that Helaine graphed the following equation :
[tex]12x-4y=3~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We are to find the slope of the line.
We know that
the slope-intercept form of a straight line is given by
[tex]y=mx+c,[/tex] where m is the slope of the line.
From equation (i), we have
[tex]12x-4y=3\\\\\Rightarrow 4y=12x-3\\\\\Rightarrow y=\dfrac{12x-3}{4}\\\\\\\Rightarrow y=3x-\dfrac{3}{4}.[/tex]
Comparing with the slope-intercept form, we get
slope, m = 3.
Thus, the required slope of the given line is 3.

A petroleum laboratory technician is working at a petroleum storage depot in the oil-analysis laboratory. The lab tech is running tests on a sample from a 45-gallon oil-solvent mixture that contains 18 gallons of oil.
What is the ratio of the number of gallons of oil to the number of gallons of solvent?
The ratio of the number of gallons of oil to the number of gallons of solvent is 2:3.
Explanation:The ratio of the number of gallons of oil to the number of gallons of solvent can be determined by subtracting the number of gallons of oil from the total volume of the mixture and then dividing by the number of gallons of solvent. In this case, the total volume of the mixture is 45 gallons and the number of gallons of oil is 18. So, the number of gallons of solvent is 45 - 18 = 27. Therefore, the ratio of the number of gallons of oil to the number of gallons of solvent is 18:27, which can be simplified to 2:3.
