What is her hourly wage?
In linear equation, $5.26 is her hourly wage .
What is linear equation in math?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.Ax+By=C is the typical form for linear equations involving two variables. A standard form linear equation is, for instance, 2x+3y=5. It is rather simple to locate both intercepts when an equation is stated in this way (x and y).Serita worked 6 h and earned $31.50.
1 hour of wage of serita = $31.50/6
= $5.26

To encourage Bob to do his homework better, his mother said she would pay him 10 cents for each right answer and subtracts 5 cents for each wrong answer. If he earned 20 cents after doing 32 problems, how many problems did Bob get right? How many did he get wrong? How many would he have to get right to earn more than a dollar?
To get more than a dollar, Bob needs to earn at least 110 cents. Bob already has 20 cents. He needs to get 9 right to earn over a dollar.
If Bob gets 9 right, Bob would earn 90 cents more. 90 + 20 = 110 cents = $1.1
What is an Algebraic Expression?Algebraic Expression: An algebraic expression in mathematics is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.). Expressions are made up of terms
Bob correctly answered 12 questions, so
Bob mis-answered 20 questions.
Let x be the number of questions that he correctly answered.
Let y be the number of questions that he answered incorrectly.
Bob's mother promised to give him 10 cents for each accurate response. This implies that he would receive $10x for correctly answering x questions.
Bob's mother informed him that she would deduct $5 for each incorrect response. This implies that if he answers y questions incorrectly, Bob will forfeit.

Bob completed 32 problems, which indicates that
x + y = 32
After solving 32 tasks, Bob received 20 cents, which indicates that
10x - 5y = 20 - - - - - - - - -1
When x = 32 - y is substituted into equation 1, it produces
10(32 - y) - 5y = 20
320 - 10y - 5y = 20
- 10y - 5y = 20 - 320
- 15y = - 300
y = - 300/ -15 = 20
Substituting y = 20 into x = 32 - y, it becomes.
x = 32 - 20 = 12
To get more than a dollar, Bob needs to earn at least 110 cents. Bob already has 20 cents. He needs to get 9 right to earn over a dollar.

Three monkey's walk into a motel on the Curious George Hotel and ask for a room. The desk clerk says a room costs 30 bananas, so each monkey pays 10 bananas towards the cost.Later, the clerk realizes he made a mistake, that the room should have been 25 bananas. He calls the bellboy over and asks him to refund the other 5 bananas to the 3 monkeys. The bellboy, not wanting to make a mess dividing the 5 bananas three ways, decides to lie about the price, refunding each monkey I banana, keeping the other 2 bananas for himself. Ultimately cach monkey paid 9 bananas towards the room and the bellboy got 2 bananas, for a total of 29 bananas. But the original charge was 30 bananas.Where did the extra 1 banana go?

B A In this figure, AB || CD and m/3 120 What is m/6? D Enter your answer in the box.
Answer
Explanation
AB is parallel to CD and then, there's a transversal that cuts across the two lines. We are given that Angle 3 = 120°
But we ca see from the figure that Angle 3 and Angle 2 lie on the same straight line.
And we know that the sum of angle on a straight line is 180°.
Hence,
(Angle 3) + (Angle 2) = 180°
120° + Angle 2 = 180°
Angle 2 = 180° - 120°
Angle 2 = 60°
Then again, we can see that AAA

2y^2-5y=12. can someone help me solve the quadratic equation using the quadratic formula.
Answer:
y = 4 y = -3/2 = -1.5Step-by-step explanation:
According to quadratic formula:
y = - b ± √ b²- 4ac / 2a
y = - (-5) ± √ -5²- 4(2x-12) / 2(2)
y = 5 ± √ 25 - 4(-24) / 4
y = 5 ± √ 25 - (-96) / 4
y = 5 ± √ 121 / 4
y = 5 ± √ (11)² / 4
y = 5 ± 11 / 4
Now either,
y = 5 + 11 / 4
y = 4
Or,
y = 5 - 11 / 4
y = -3/2 = -1.5

compare the x-intercepts for the two linear functions represented in the table below. which of the following statements is true?
• Given Function A:
[tex]-4x+2y=-2[/tex]You need to remember that, by definition, the value of "y" is zero when the function intersects the x-axis.
Therefore, you need to set up that:
[tex]y=0[/tex]Substitute this value into the function and then solve for "x", in order to find the x-intercept:
[tex]\begin{gathered} -4x+2(0)=-2 \\ -4x=-2 \\ \\ x=\frac{-2}{-4} \\ \\ x=\frac{1}{2} \end{gathered}[/tex]• Given that Function B passes through these points:
[tex](0,-1),(3,2)[/tex]You need to determine the equation of the line, in order to find the x-intercept using it.
The Slope-Intercept Form of the equation of a line is:
[tex]y=mx+b[/tex]Where "m" is the slope of the line and "b" is the y-intercept.
By definition, the value of "x" is zero when the function intersects the y-axis. Therefore, knowing the first point given in the exercise (whose x-coordinate is zero), you can determine that, for this line:
[tex]b=-1[/tex]Substitute "b" and the coordinates of the second point into this equation:
[tex]y=mx+b[/tex]And then solve for "m":
[tex]\begin{gathered} 2=m(3)-1 \\ 2+1=3m \\ \\ \frac{3}{3}=m \\ \\ m=1 \end{gathered}[/tex]Therefore, the equation of Function B in Slope-Intercept Form is:
[tex]y=x-1[/tex]Now you can find the x-intercept by using the procedure used for Function A:
[tex]\begin{gathered} 0=x-1 \\ x=1 \end{gathered}[/tex]You know that:
[tex]\frac{1}{2}<1[/tex]Hence, the answer is: Third option.
Describe the relationship between GPE and kinetic energy
Step-by-step explanation:
when an object gains height, Kinetic energy in the object is converted to gpe. gpe = mgh
when an object loses height and falls down, the object is accelerated by gravity (free fall) therefore, gains velocity which means the gpe is converted to kinetic energy.
kinetic energy = 1/2 × m × v²
this is applicable only when the mass is constant.

Santiago is going to invest in an account paying an interest rate of 3.3% compounded annually. How much would Santiago need to invest, to the nearest ten dollars, for the value of the account to reach $81,000 in 16 years?
Santiago needs to invest 50467.3 dollars for the value of the account to reach $81,000 in 16 years at a rate of 3.3%.
What are simple and compound interests?Simple interest is often a predetermined percentage of the principle amount borrowed or lent paid or received over a specific time period.
Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.
Given Santiago is going to invest in an account paying an interest rate of 3.3% compounded annually for the value of the account to reach $81,000 in 16 years.
We know the formula of compound interest which is A = P(1 + r/100)ⁿ,
where A = Amount, P = Principle, n = Time in years and r = rate percentage.
∴ 81000 = P( 1 + 3.3/100)¹⁶.
81000 = P( 1 + 0.03)¹⁶.
81000 = P( 1.03)¹⁶.
81000 = P×1.605.
P = 81000/1.605
P = 50467.3 dollars.

Sarah took a survey asking students if they prefer summer or winter sports. She found that 12 out of 18 students prefer summer sports. Determine what fraction of students prefers winter sports. Write your response in simplest form Explain how you found your answer. (answer tomorow i have a test)
If 12 out of 18 students prefer summer sports, then the fraction of students prefer winter sports is 33.33%
Total number of students = 18
The number of student prefer summer sports = 12
Then the number of student who prefer winter sports = Total number of students - The number of student prefer summer sports
= 18 - 12
= 6 students
The percentage is number that can be represented as the fraction of 100.
It is denoted by the percentage sign "%"
Then the fraction of students who prefer winter sports = (Number of student who prefer winter sports /Total number of students )×100
