a wheel for a wheel of winning game makes one revolution in 4 seconds. What is their unit rate in terms of minutes
It will take 15 revolutions per minute.
What is the unit rate?
An item's unit rate is its price for one of them. This is expressed as a ratio with a one as the denominator. For instance, if you covered 70 yards in 10 seconds, you covered 7 yards on average every second. Seven yards in one second and 70 yards in ten seconds are both ratios, but only one of them is a unit rate.
Here, we have
Given: a wheel for a wheel of winning game makes one revolution in 4 seconds.
Take a time for 1 revolution = 4 seconds
Assume that the unit rate in terms of revolutions per minute is x.
1 rev/4 second = x rev/60 second
4x = 60

The lengths of two sides of a triangle are 4 inches and 7 inches.
What is a possible length, in inches, of the third side?
A possible length, in inches, of the third side is equal to 4 inches.
What is the triangle inequality theorem?In Euclidean geometry, the Triangle Inequality Theorem states that the sum of any two sides of a triangle must be greater than or equal (≥) to the third side of the triangle.
Mathematically, the Triangle Inequality Theorem is represented by this mathematical expression:
b - c < n < b + c
Where:
n, b, and c represent the side lengths of this triangle.
By applying the Triangle Inequality Theorem, the possible side lengths of the triangle's third side is given by:
b - c < n < b + c
7 - 4 < n < 7 + 4
3 < n < 11.

A and B are independent events if, the probability of getting a red convertible is 0.10
What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
Given that, in a video game, the probability of getting a red car is 0.25 (event A), and the probability of getting a convertible is 0.40 (event B).
We need to identify the condition for events A and event B being independent events.
We know that,
The events in probability two are independent if event one does not affect the other one.
The formula for independent events =
P(A∩B) = P(A) x P(B).
So,
P(A) = 0.25 and P(B) = 0.40
P(A∩B) = P(A)xP(B)
= 0.25 x 0.4
= 0.10
Hence, the events A and B are independent events if, the probability of getting a red convertible is 0.10

house is 24 7/12 feet high. What is the height of the attic?
The height of the attic in Mr. Lee's house is 6 1/3
What is an equation?An equation is an expression that shows the relationship between numbers and variables using mathematical operators like addition, subtraction, multiplication and division. Equations can be linear, quadratic.
Mr. Lee's house has two stories and an attic. Therefore:

Answer:
The number of large bars of chocolate sold is:
1/4 x 208 = 52
The number of small bars of chocolate sold is:
208 - 52 = 156
The total amount of money earned from selling the large bars of chocolate is:
52 x e1 = e52
The total amount of money earned from selling the small bars of chocolate is:
156 x 60p = £93.60
To convert e52 to pounds, we need to multiply by the exchange rate. Let's assume that the exchange rate is £1 = e1.20.
So, e52 = £52 x 1.20 = £62.40
Therefore, the total amount of money earned from selling all 208 bars of chocolate is: £62.40 + £93.60 = £156

how to calculating rf values?
Answer:
Step-by-step explanation:
Rf values (retention factor values) are used in thin layer chromatography (TLC) to measure the separation of components in a mixture. They are calculated as follows:
Rf = (distance traveled by the solute) / (distance traveled by the solvent)
The distance traveled by the solute is measured from the origin (the spot where the sample was applied) to the final position of the solute on the TLC plate. The distance traveled by the solvent is measured from the origin to the solvent front (the point where the solvent stops moving up the plate).
It is important to note that Rf values are unique to each solute and are dependent on the solvent used, the type of TLC plate, and the conditions of the experiment (such as the temperature and humidity). To ensure accurate comparison of Rf values, it is necessary to standardize the conditions of the experiment.
Calculating Rf values is a crucial step in the interpretation of TLC data, as it allows for the identification of the components of a mixture based on the unique Rf values of each solute.

What is the slope of a line perpendicular to a horizontal line?
The slope of a horizontal line perpendicular to a horizontal line is infinity or undefined.
The slope of a line is the that of the inclination that is makes with a horizontal line.
So, the slope of horizontal line is 1 because the value of tam(0 degrees) is also 1.
A line that is perpendicular to the horizontal line will have a the value of angle to be 90 degrees and we know that,
tan (90 degrees) = undefined/infinity
So, here we are concluding that the slope of any line that is being lying perpendicularly on any horizontally lying line is infinity or undefined.
