What is the solution to the equation 1 / 4 x = 5?
x = 4 / 5
x = 5 / 4
x = 20
x = 1
Answer:
The solution to the equation 1/4 x = 5 is '' x = 20''
Step-by-step explanation:
you take ''1/4'' and multiply it by ''20'' and the answer you'll get is ''5''
The solution to the equation 1 / 4 x = 5 is found by isolating x. After multiplying both sides of the equation by 4, you find that x = 20.
Explanation:The solution to your equation, 1 / 4 x = 5, can be found using the principles of algebra. This equation is asking us 'What value of x can I multiply by 1/4 to equal 5?'
The best way to find the solution is to isolate x on one side of the equation. In this case, you'll start by multiplying both sides of the equation by 4. Now your equation looks like this:
1/4 x * 4 = 5 * 4
Simplifying the equation, you'll get:
x = 20
Therefore, you can see that the solution to the equation 1/4 x = 5 is x = 20.

employees whose rate of commission increases as their sales increase are paid a(n) ___________.
Answer: Then you should pay her 4$ one hour
Step-by-step explanation:
Employees who earn increased commissions as their sales increase are paid a progressive commission. This method incentivizes employees to work harder to sell more, as their commission rate increases with sales volume.
Explanation:Employees whose rate of commission increases as their sales increase are paid a progressive commission. With this method of remuneration, the more sales an employee makes, the higher their rate of commission becomes. This strategy is popular with both economists and the general public because it effectively incentivizes employees to work harder and achieve higher sales, leading to an increase in the overall performance of the business.
For example, a salesperson may earn a 10% commission on sales up to $10,000. However, any sales beyond that might attract a 15% commission rate, encouraging the employee to sell more. Such progressive commission schemes are common in sales-driven industries like real estate and retail.

And event organizer is reserving rooms for two companywide events. For the quarterly meeting this month she reserved 2 conference rooms and 5 ballrooms which can seat a total of 238 attendees. for safety training next month she reserved 4 conference rooms and 5 ball rooms which can seat 286 attendees. How many attendees can each room accommodate?
Final answer:
The conference rooms can accommodate approximately 34 attendees each, and the ballrooms can accommodate approximately 31 attendees each.
Explanation:
To find out how many attendees each room can accommodate, we need to divide the total number of attendees by the total number of rooms.
For the quarterly meeting, there are 2 conference rooms and 5 ballrooms, which can seat a total of 238 attendees. To find out how many attendees each room can accommodate, we divide 238 by 7 (2 + 5), which gives us approximately 34 attendees per room.
For the safety training event, there are 4 conference rooms and 5 ballrooms, which can seat a total of 286 attendees. Dividing 286 by 9 (4 + 5) gives us approximately 31 attendees per room.

Which line is a graph of the equation: -2x + 5y=10
Answer:
Step-by-step explanation: first, find y by itself by adding 2x to the other side then diving by the 5y to get y=2/5x +2! Rise 2, run 5 from your start at positive 2 on the graph and you should get line a!!!
The graph of the equation -2x + 5y = 10 has a positive slope of 2/5 and a y-intercept of 2. None of the provided options accurately describe the graph of the equation, as they indicate incorrect y-intercept values and describe the slope incorrectly.
Explanation:To find which line is a graph of the equation -2x + 5y = 10, we need to identify the slope and the y-intercept of the line. To do this, we should rearrange the equation into slope-intercept form, which is y = mx + b where m is the slope and b is the y-intercept.
Rearranging the equation, we get:
5y = 2x + 10
y = (2/5)x + 2
The slope is the coefficient of x, which is 2/5, and the y-intercept is the constant term, which is 2. The line has a positive slope, and based on the slope-intercept form, it rises on the graph as the x-value increases. Therefore, option d with a positive slope and a y-intercept of 50 must have a typo since our y-intercept is 2. The correct interpretation would be that the line gradually moves upward on the graph as the x-value increases, thanks to its positive slope.
Hence, none of the provided options describe the graph of the equation -2x + 5y = 10 accurately because the y-intercept should be 2, not 50, and the slope is positive. Keep in mind that a positive slope results in an upward, not a downward, trend as x increases.
A bank offers a home improvement loan with simple interest at an annual rate of 12%. J.T. borrows an amount of $14,000 to pay back over 3 years. How much will he pay back altogether? Explain how you found the total amount.
12%*14000*3
Which is 5040
Therefore, it will have to pay back $4050
J.T. will pay back a total of $18,480 altogether.
To calculate the total amount J.T. will pay back, we can use the formula for simple interest:
[tex]\[I = P \times r \times t\][/tex]
Where:
- (I) = Interest
- (P\) = Principal amount (the initial loan amount)
- (r) = Annual interest rate (in decimal form)
- (t) = Time (in years)
Given that J.T. borrows $14,000 at an annual interest rate of 12% for 3 years, we can plug these values into the formula:
[tex][I = 14000 \times 0.12 \times 3\][/tex]
[I = 5040]
So, the total interest J.T. will pay is $5,040.
To find the total amount J.T. will pay back, we add the interest to the principal:
[Total amount = Principal + Interest]
[Total amount = 14000 + 5040]
[Total amount = 18440]
Therefore, J.T. will pay back a total of $18,480 altogether.
In summary, by using the formula for simple interest, we determined the interest amount J.T. will pay over the 3-year period, and then added it to the principal amount to find the total repayment amount.
Complete question:
A bank offers a home improvement loan with simple interest at an annual rate of 12%. J.T. borrows an amount of $14,000 to pay back over 3 years. How much will he pay back altogether? Explain how you found the total amount.

What are the roots of x in -10x2 + 12x − 9 = 0?
To find the roots of the quadratic equation -10x^2 + 12x - 9 = 0, we can use the quadratic formula:
x = \frac{-b ± \sqrt{b^2 - 4ac}}{2a}
where
a is the coefficient of x^2, which is -10,
b is the coefficient of x, which is 12,
c is the constant term, which is -9.
First, let's identify the coefficients in our equation:
a = -10
b = 12
c = -9
Next, we will calculate the discriminant (Δ) using the formula:
Δ = b^2 - 4ac
Plug in the values of a, b, and c:
Δ = (12)^2 - 4*(-10)*(-9)
Δ = 144 - 4 * 10 * 9
Δ = 144 - 360
Δ = -216
Since the discriminant is negative, the quadratic equation has two complex roots. We will still use the quadratic formula to find them:
x = \frac{-b ± \sqrt{Δ}}{2a}
Substitute b, Δ, and a into the formula:
x = \frac{-12 ± \sqrt{-216}}{2 * (-10)}
Now, let's split the square root of the negative discriminant into real and imaginary parts:
√(-216) = √(216) * √(-1) = 14.697 * i
where i is the imaginary unit such that i^2 = -1. Substituting this into our quadratic formula gives:
x = \frac{-12 ± 14.697i}{-20}
Now, divide both the real and imaginary parts by -20:
x₁ = \frac{-12}{-20} + \frac{14.697i}{-20}
x₂ = \frac{-12}{-20} - \frac{14.697i}{-20}
Simplify those equations:
x₁ = \frac{12}{20} - \frac{14.697i}{20}
x₂ = \frac{12}{20} + \frac{14.697i}{20}
Further simplify by reducing the fractions:
x₁ = 0.6 - 0.73485i
x₂ = 0.6 + 0.73485i
Therefore, the roots of the quadratic equation -10x^2 + 12x - 9 = 0 are approximately x₁ = 0.6 - 0.73485i and x₂ = 0.6 + 0.73485i.
The glass for a picture window is 8 feet wide. The door it must pass
through is 3 feet wide. How tall
must the door be for the glass to
pass through the door? Round to
the nearest tenth.
Using Pythagorean theorem, for the 8-feet wide picture window to pass through the 3-feet wide door, the door must be at least approximately 7.4 feet tall.
Explanation:The picture window here is a rectangular sheet of glass. The longer side (8 feet) must fit through the door. The door is only 3 feet wide, which means that the 8-foot side of the window must be angled to pass through the door in vertical orientation.
To calculate the height of the door needed, consider the Pythagorean theorem which states that in a right triangle, the square of the hypotenuse (longest side) equals the sum of the squares of two sides (a2 + b2 = c2). Here 'a' is the width of the door (3 feet) and 'c' is the diagonal length of the window (8 feet). Solving for 'b' which represents the door's required height, we get:
b2 = c2 - a2
b2 = 82 - 32
b = sqrt(64 - 9) = sqrt(55)
Therefore, b is approximately 7.4 feet.
So the door must be at least 7.4 feet tall to pass the 8-feet picture window through it when angled vertically.

The door needs to be approximately 21.3 feet tall for the glass to pass through.
Explanation:To determine the height of the door, we need to consider that the glass is 8 feet wide. Since the door is only 3 feet wide, the glass needs to fit through a smaller opening. We can use similar triangles to find the height of the door. Let's set up a proportion:
8 / 3 = H / 8
Cross-multiplying, we get:
3H = 64
H = 64/3
Therefore, the door needs to be approximately 21.3 feet tall for the glass to pass through.

The slope of the line whose equation is 3y + 2x = 1 is: A.)-2/3 B.)-3/2 C.)1/3
Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 3y + 2x = 1 into this form
Subtract 2x from both sides
3y = - 2x + 1 ( divide all terms by 3 )
y = - [tex]\frac{2}{3}[/tex] x + [tex]\frac{1}{3}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{2}{3}[/tex] → A
By rearranging the equation 3y + 2x = 1 into slope-intercept form, y = mx + b, we find that the slope of the line is -2/3. The correct answer is A.) -2/3.
The slope of the line whose equation is 3y + 2x = 1 is found by solving for y to get the line into slope-intercept form, which is y = mx + b, where m represents the slope.
First, subtract 2x from both sides of the equation: 3y = -2x + 1.Next, divide each term by 3 to solve for y: y = (-2/3)x + 1/3.Now that the equation is in slope-intercept form, we can see that the slope m is -2/3. Therefore, the correct answer is A.) -2/3.

Answer:
C - 2 2/9
Step-by-step explanation:
7 1 /2 x + 3 2/ 3 = −13
Subtract 3 2/3 from each side
7 1 /2 x + 3 2/ 3 - 3 2/3 = −13 - 3 2/3
7 1/2x = -16 2/3
Change each mixed number to an improper fraction
7 1/2 = (2*7 +1)/2 = 15/2
16 2/3 = (3*16+2)/3 = 50/3
15/2 x = -50/3
Multiply each side by 2/15 to isolate x
2/15 * 15/2 x = -50/3 * 2/15
x = -100/45
Simplify
x = -20/9
Change back to a mixed number

Miryam Williams earns a 3.5% commission on all sales. She also receives a $500 bonus if her commission exceeds $5,000. Her total sales were $92,500. What was her total pay?
Final answer:
Miryam Williams' total pay is $3,237.50.
Explanation:
To calculate Miryam Williams' total pay, we first need to calculate her commission.
Her commission is 3.5% of her total sales, which is $92,500.
Commission = 3.5% × $92,500 = $3,237.50.
Next, we need to determine if Miryam's commission exceeds $5,000.
Since her commission is $3,237.50, it does not exceed $5,000. Therefore, she does not receive the $500 bonus.
Finally, to calculate her total pay, we sum her commission and the bonus (which is $0 in this case).
Total Pay = Commission + Bonus = $3,237.50 + $0 = $3,237.50.
