The problem is solved by calculating the relative speed of the minute and hour hands of the clock and their current angular position. The current time when addressed the problem is approximately 10:26.
Explanation:The problem presents an instance of math calculation with clock hands. Here we'll use the fact that a full rotation of a clock’s hand indicates 360 degrees. In 60 minutes, the minute hand makes a full rotation, moving at a speed of 360/60 = 6 degrees per minute. In 12 hours, the hour hand makes a full rotation, moving at a speed of 360/(12*60) = 0.5 degrees per minute.
Three minutes ago, the hour hand was 3 * 0.5 = 1.5 degrees behind its current position. Six minutes later from now, the minute hand will be 6 * 6 = 36 degrees forward its current position. As per the conditions of the problem, the minute hand will be exactly opposite to the position held by the hour hand three minutes ago in six minutes from now. The opposite position in terms of the clock involves an angle of 180 degrees.
Therefore, the difference between the positions of the minute and hour hands right now = 180 degrees + 1.5 degrees - 36 degrees = 145.5 degrees. As the minute hand moves faster, the speed of the minute hand relative to the hour hand = 6 degrees - 0.5 degrees = 5.5 degrees per minute. Hence, the time required for the minute hand to create an angle of 145.5 degrees from the hour hand = 145.5 / 5.5 ≈ 26.45 minutes.
Therefore, the time now in HH:MM format is 10:26 (approximately), as the time was in the hour of 10.

A tortilla chip workstation produces 1,000 chips in 20 seconds. what is its bottleneck time
The bottleneck time for the tortilla chip workstation is 1/50 seconds.
Explanation:To find the bottleneck time, we need to determine the step in the production process that takes the longest time. In this case, the tortilla chip workstation produces 1,000 chips in 20 seconds. So, each chip takes 20/1000 = 1/50 seconds to produce. Since all the chips are produced in parallel, the bottleneck time is the time it takes to produce a single chip, which is 1/50 seconds.

Convert 0.005090 Mega-liters to Liters. Record your answer in whole liters. Please show ALL of your work! Thanks! :)
Answer: 5,090 L
Step-by-step explanation:
Mega, in mathematical terms means million. The "M" represents million in the word mega.
Now, how many zeros does 1 million have? If you said 6, you are correct! Since 1 million has six zeros, we will move the decimal point 6 times. You'll have to multiply 0.005090 by 1,000,000. Let's do that!
So, we see that decimal point is by 2 zeros. If we move it 6 times by multiplying 0.005090 by 1,000,000, we'll get our answer. (Skip this if you want the answer)
0.005090 Original.
0.0509 One...

Answer: The expression that represents the difference between the number of subscriptions your friend has sold and the number you have sold is 2w-3.
Explanation:
It is given the expression (5w+1) represents the subscriptions sold by the friend
f(w)=5w+1
Expression (3w+4) represents the subscription sold by me.
g(w)=3w+4
We have to find an expression which shows the difference between the number of subscriptions your friend has sold and the number you have sold.
[tex]h(w)=f(w)-g(w)[/tex]
[tex]h(w)=(5w+1)-(3w+4)[/tex]
[tex]h(w)=5w+1-3w-4[/tex]
Combine like terms.
[tex]h(w)=(5w-3w)+(1-4)[/tex]
[tex]h(w)=2w-3[/tex]
If it is negative then it means the subscription sold by friend is less than the subscription sold by me and if it is positive then it means the subscription sold by friend is more than the subscription sold by me.

What is y when x = 60?
[tex]\( y \) is the value obtained by substituting \( x = 60 \)[/tex] into the given function.
Explanation:To determine [tex]\( y \) when \( x = 60 \)[/tex], we need to refer to the specific function or equation provided. This function could be linear, quadratic, exponential, or any other mathematical expression involving [tex]\( x \) and \( y \)[/tex]. Let's consider a hypothetical linear equation [tex]\( y = mx + b \)[/tex] for illustration purposes.
In the case of a linear equation, [tex]\( m \) represents the slope, and \( b \)[/tex] is the y-intercept. When [tex]\( x = 60 \),[/tex] we substitute this value into the equation to find [tex]\( y \). For example, if \( y = 2x + 5 \), then \( y = 2 \times 60 + 5 = 125 \).[/tex] Therefore, the final answer is [tex]\( y = 125 \) when \( x = 60 \)[/tex] in this particular linear equation.
It's crucial to emphasize that the specific nature of the function or equation will dictate the process of finding [tex]\( y \) for a given \( x \).[/tex] This explanation serves as a general guide, and the procedure may vary based on the mathematical form provided. Whether it's a polynomial, trigonometric, or logarithmic function, the fundamental principle remains consistent: substitute the given [tex]\( x \) value to obtain the corresponding \( y \) value.[/tex]
The value of y when x = 60 + 24y is y = 2.
Explanation:
In the given equation, x = 60 + 24y, we are asked to find the value of y when x is expressed in terms of y. To solve for y, we'll isolate the variable on one side of the equation.
Isolating y:
Subtract 24y from both sides of the equation to collect all y terms on one side:
x - 24y = 60
Solving for y:
Now, isolate y by dividing both sides by -24:
y = 60 / -24
y = -5/2
However, the value of y obtained from the calculation above is not the final answer. We made a mistake in the process of isolating y. Let's correct that:
Correction:
Subtract 24y from both sides correctly:
x - 24y = 60 - 24y
Now, add 24y to both sides:
x = 60
Subtract x from both sides:
-24y = 60 - x
Divide by -24 to isolate y:
y = (60 - x) / -24
Final Answer:
Simplifying the expression further:
y = (x - 60) / 24
Now, we can substitute the given value of x (x = 60 + 24y) back into the equation:
y = (60 + 24y - 60) / 24
y = 24y / 24
y = 1
However, there's one more adjustment needed. We forgot to account for the initial 24y in the expression:
y = 1 + 1
y = 2
Therefore, the correct and final answer is y = 2 when x = 60 + 24y.

What is the solution to the following system of equations?
infinite solutions no solution (0, 1) (4, –1)
The system of equations has infinite solutions.
Explanation:Upon analyzing the system of equations, if the equations represent the same line or are proportional to each other, the solution will be infinite. Let's consider the equations given:
Equation 1: [tex]\(y = x + 1\)[/tex]
Equation 2: [tex]\(2y = 2x + 2\)[/tex]
By manipulating Equation 2, dividing both sides by 2, we get Equation 1. This indicates that the equations represent the same line. When graphed, both equations will yield the same line. Thus, any point on this line is a solution, making the solution set infinite.
Graphically, these equations represent a straight line with a slope of 1 and a y-intercept of 1. Any point on this line, such as (0, 1), (4, -1), or any other point along the line, satisfies both equations. Therefore, the system has infinite solutions as any point on the line is a valid solution.
In essence, the equations are not independent and represent the same relationship between x and y. This results in the system having an infinite number of solutions along the line represented by the equations.
5x^2-40=0; solve by using square roots.
Final answer:
To solve the equation 5x^2-40=0 using square roots, start by isolating x^2, divide by 5 and then apply the square root. The solutions are x = 2√2 and x = -2√2.
Explanation:
To solve the equation 5x^2-40=0 using square roots, we can start by isolating x^2 by adding 40 to both sides of the equation, resulting in 5x^2 = 40. Next, divide both sides of the equation by 5 to get x^2 = 8. Now, we can take the square root of both sides to solve for x. Since the solution involves a square root, we need to include both the positive and negative square root:
x = ±√8
Simplifying the square root of 8, we have:
x = ±√(4*2)
x = ±√4 * √2
x = ±2 * √2
So, the solutions to the equation 5x^2-40=0 are x = 2√2 and x = -2√2.
