It takes a turtle 3 1/4 hours to walk 1/2 miles how many hours does it take to walk one mile?
Answers
Using the principle of proportional relationship, the time taken by the turtle to walk one mile is 2.1667 hours
What is proportional relationship?
Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".
Creating a system of proportional expression :
Cross multiply :
1.5t = (3.25 × 1)
1.5t = 3.25
Divide both sides by 1.5
t = (3.25 ÷ 1.5)
t = 2.1667 hours
Therefore, the time taken per mile is 2.1667 hours

The turtle needs 2.16 hours to move a mile using the proportional relationship principle.
What does the word "proportional" mean?
Proportional relationships form when the ratios of two variables are equal. The fact that one variable is consistently equal to the constant value of the other in a proportionate connection is another way to think of them. The "constant of proportionality" is the name of this constant.
For instance, the time it takes a train to travel 50 kilometers per hour is equal to the time it needs to travel 250 kilometers in 5 hours. e.g., 250km/5 hours at 50 km/h.
Establishing a proportional expression system
Cross multiply :
1.5t = (3.25 × 1)
1.5t = 3.25
t = (3.25 ÷ 1.5)
t equals 2.16 hours
Consequently, the time required for each mile is 2.16 hours.

How would you explain the relationship between the real zero(s) of the function and x-intercept(s) of the graph? O O O Since the graph crosses the x-axis at x = -2, the function has a real zero of x = -2. Since the graph never crosses the x-axis, the function has no real zeros. Since the graph eventually crosses the x- axis, the function has a real zero. Since the graph crosses the y-axis at 9, the function results in a real zero of x = 9 ?.

Decide whether the random variable x is discrete or continuous. Explain your reasoning. Let x represent the time it takes to run a mile. Is the random variable x discrete or continuous?
Answers
The variable represents time. The time in which a person runs a mile will depend on the speed of that person, and that can take almost any value, thus, here the variable is continuous.
Is the variable discrete or continuous?First, when a variable is discrete and when it is continuous?
A variable is discrete if it only can take some selected values on a given interval, while a variable is continuous if it can take any value (or at least a dense set) of values in that interval.
For example, the numbers that one can roll on a dice form a discrete set, because the values can only be {1, 2, 3, 4, 5, 6}, just to given an example.
Now, in this case, the variable represents time. Time almost always is a continuous variable, in this case, the time is the time in which a person runs a mile. So that variable can take almost any value (depends on the speed of the person).
So we conclude that this is a continuous variable.

The plot of the points on a coordinate plane is added as an attachment
How to plot the point on a coordinate plane?The coordinate of the point on a coordinate plane is given as
Point = (-3 1/2, -1 1/4)
As a general rule, we express the above coordinate as follows:
(x, y) = (-3 1/2, -1 1/4)
The next step is to remove the bracket
So, we have the coordinates into x and y coordinates
This is represented as
x = -3 1/2 and y = -1 1/4
The interpretation of the above equations is:
(-3 1/2, -1 1/4) is at a point that is 3 1/2 points to the left of the origin (-3 1/2, -1 1/4) is at a point that 1 1/4 points below the originNext, we plot the points

Demand for bikes has suddenly increased, and the market price has risen from $50 to $60.
In three to five sentences, explain how this change will affect profits.
Answers
Answer:
profits will increase so with that being said the supply of them dropped if demand increased getting bikes will be harder for competing business in the area and so therefore if you have 200 bikes and others have 50 bikes your gonna make way more profit and for the people with 50 bikes they will gain and lose profits because when they run out of bikes they have to buy more and they are more expensive because of the demand on them
Step-by-step explanation:
The explanation regarding the change of price that impact the profits should be explained below.
Impact on profit:The profit should rise when the supply should fall. In the case when I have 200 bikes while the other should have 50 bikes so here I make more profit however the other people will gain but the profit should be lost since the bikes should be out of the stock and at the same time they need to buy more that should be more expensive due to the demand.

Answer:
No Real Roots
Step-by-step explanation:
Hello!
To determine the types of roots a quadratic has, we can use the Discriminant.
Refer to the quadratic formula: \(x = \frac{-b\pm \sqrt{\bold{b^2 - 4ac}}}{2a}\)
The bolded part (b² - 4ac) is the Discriminant.
Determining the rootsPositive Discriminant gives us 2 roots that are real (can be rational or irrational)Zero Discriminant gives us 1 root that is real and rational (can also be known as a double root)Negative Discriminant gives us 2 roots that are not real, or imaginary.We can plug in our values from the quadratic into the Discriminant Formula b² - 4ac.
Solve\(b^2 - 4ac\)\(3^2 - 4(10)(6)\)\(9 - 240\)\(-231\)Since the discriminant is negative, there are two imaginary roots, or roots that don't exist.
The are no real roots for this quadratic.

The scale from a playground to this drawing is 5 ft to 1 cm. The scale from the same playground to another drawing is 8 ft to 1 cm. What are the side lengths of the playground in the other scale drawing?
The side lengths of the playground in the other scale drawing is \(\frac{5a}{8}\).
By using geometry we answer this question.
Geometry is nothing but the branch of mathematics which deals with measurements of shapes.
Here, we take the scale from a playground to this drawing as "a" and The scale from the same playground to another drawing as "b".
First, we see the scale from a playground to this drawing.
\(\frac{a}{l}= \frac{1}{5}\)
\(l=5a\)
Now we see the scale from the same playground to another drawing.
\(\frac{b}{l} =\frac{1}{8}\)
\(b=\frac{l}{8}\\\)
Here, l=5a then
\(b=\frac{5a}{8}\)
Therefore, the side lengths of the playground in the other scale drawing is \(\frac{5a}{8}\).

Answer the questions below about the quadratic function. f(x) = - 2x ^ 2 + 8x - 12
Answers
Answer:
The function has a maximum
The function's maximum value is y = - 4
The maximum value occurs at x = 2
Explanation:
The given function is
f(x) = - 2x^2 + 8x - 12
The leading coefficient(the coefficient of the term with the highest exponent, x^2) is - 2. Since the leading coefficient is negative, the parabola would open downwards. This means that it would have its highest point of vertex at the top. Thus,
the function has a maximum
Recall, the standard form of a quadratic equation is expressed as
y = ax^2 + bx + c
By comparing both equations,
a = - 2, b = 8, c = - 12
We would find the x coordinate of the maximum point by applying the formula,
x = - b/2a
By substituting the given values into the formula, we have
x = - 8/2 * - 2 = - 8/- 4
x = 2
We would find the y coordinate or maximum value by substituting x = 2 into
y = - 2x^2 + 8x - 12
y = - 2(2)^2 + 8(2) - 12
y = - 8 + 16 - 12
y = - 4
Thus,
the function's maximum value is y = - 4
The maximum value occurs at x = 2
