Ai Mi went to the store to buy some chicken. The price per pound of the chicken is $3. 50 per pound and she has a coupon for $2. 50 off the final amount. With the coupon, how much would Ai Mi have to pay to buy 3 pounds of chicken? Also, write an expression for the cost to buy pp pounds of chicken, assuming at least one pound is purchased.
Ai Mi have to pay $10.50 to buy 3 pounds of chicken.
An expression for the cost to buy pp pounds of chicken, assuming at least one pound is purchased.
Cost = (3.5 * pp) - 2.5
The cost to buy 3 pounds of chicken without the coupon would be 3 * $3.50 = $10.50
With the coupon, Ai Mi would have to pay $10.50 - $2.50 = $8.
The expression for the cost to buy pp pounds of chicken:
Cost = (3.5 * pp) - 2.5
Here, pp represents the number of pounds of chicken that Ai Mi wants to buy.

Q4. Renna went on a journey that took 712 hours. The journey started at 22 48 on Monday. At what time and day did the journey finish?
Answer:
Step-by-step explanation:
Divide 712 hours by 24 hours/day, obtaining 29 2/3 days, which in turn breaks down into 28 days plus 1 2/3 days, or 4 weeks plus 1 2/3 days. '4 weeks' takes us to a Monday, 22:48, 4 weeks after the start of the journey.
To this we add 1 2/3 days, reaching 16 hours into the Tuesday immediately following that Monday. That would be approximately 16:00 on that Tuesday, but we must work backwards 1:12 hours: subtracting 1:12 from 16:00 on Tuesday yields 14:48
The journey finishes at 14:48 4 weeks and 1 day after it began.

A falcon was recorded travelling 100 metres in 0. 93 seconds.
What was its average speed
a in m/s to 3 significant figures
The average speed of the falcon to 3 significant figures will be 107.526 m/s
Distance travelled by falcon = 100 meters
Time taken by falcon to travel the distance = 0.93 seconds
As we have the formula for finding the average speed:
Average speed is a pace defined as a quantity divided by the time required to obtain that quantity. Meters per second is the SI unit of speed. The formula S = d/t is used to compute average speed, where S is the average speed, d is total distance, and t is total time.
Average speed can be find by simply dividing the total distance covered by falcon by the total time taken by him to cover the distance.
So, the value of the average speed will be = (100 m/0.93 sec) =107.526 m/s

The sum of the first 6 terms of a geometric series is 9 times the sum of the first 3 terms, find the common series.
The exponential function y = a · 2ⁿ ⁻ ¹, where a is any real number, is generates the geometric series.
How to derive the formula of a geometric series
Geometric series are sets of elements generated by exponential functions of the form:
y = a · bⁿ ⁻ ¹, where a and b are real numbers and n is a natural number.
Where:
a - Value of the first element of the series.b - Increase rate.n - Index of the n-th element.y - Value of the n-th element.According to the statement, we derive the following expression between the two sums:
9 · a · (1 + b + b²) = a · (1 + b + b² + b³ + b⁴ + b⁵)
Now we proceed to simplify and find the value of b:
8 · a · (1 + b + b²) = a · (b³ + b⁴ + b⁵)
8 · (1 + b + b²) = b³ + b⁴ + b⁵
b⁵ + b⁴ + b³ - 8 · b² - 8 · b - 8 = 0
Then, the value of b by numerical methods is equal to 2.
The geometric series is generated by the exponential function y = a · 2ⁿ ⁻ ¹, where a is any real number.

During two games, the number of points scored by a basketball team Increased from 75 to 87. By what percentage
did the number of points scored increase?
The percentage of increase in the number of points is 16 %
What Does Percent Mean?
A ratio or figure stated as a fraction of 100 is called a percentage. The percent marker is frequently used to indicate it,%
given the data,
The basketball team's total point total was 75.
The basketball team's enhanced point total was 87.
The difference between the basketball team's total points scored and its increased points are the increase in points.
The increase in points = 87 - 75
= 12 points
So, the percentage increase in points = ( increase in points/number of points scored by the basketball team ) x 100
The percentage increase in points = ( 12 / 75 ) x 100
= 0.16 x 100
= 16 %
Therefore, the percentage increase is 16 %
Hence, the percentage of increase in the number of points is 16 %

The exponential function showing the relationship between y and t is y = 4800e^(0.0625t).
What is exponential function?An exponential function is a function of the form f(x) = bx, where b is a positive real number and x is a real number. This type of function is commonly used to model the rate of growth or decay of a quantity over time. Exponential functions have the property that their derivatives (slope) are proportional to the value of the function itself. This property makes them useful for modeling phenomena with compound growth or decay, such as populations, interest rates, and radioactive decay.
In this equation, 4800 is the original principal, 0.0625 is the interest rate (6.25%) and t is the number of years since the start of the investment. This equation can be used to calculate the value of the investment after any number of years. For example, if t = 5, then y would equal 6,842.50. This means that after 5 years, the value of the investment would be 6,842.50.

As [tex]x \to 2^-[/tex], [tex]f'(x)=1[/tex].
Step-by-step explanation:
See the attached image for the graph of f .
As [tex]x\to 2^-[/tex], the important part of the definition of f is the first part, valid for [0, 2). On the interval [1, 2), [x] = 1, so [tex]f(x)=x\cdot 1=x[/tex], and the slope is 1.
Interestingly, on the interval [2, 3), [tex]f(x)=x(x-1)=x^2-x[/tex], making [tex]f'(x)=2x[/tex]. As [tex]x \to 2^+[/tex], the value of f ' approaches 4. That accounts for the sudden change in direction at the point (2, 2) where the two pieces of the graph connect.
So although the pieces meet at (2, 2) -- f is continuous -- f does not have a (two-sided) derivative at that point because the left-hand derivative and right-hand derivative have different values. There's a "bend" in the graph.

A shape with 1 trillion sides is called a teragon. A teragon is a polygon that has an infinite number of sides, the most famous example of teragon is the Koch snowflake.
Typically, a teragon will be bounded by one or more self-similar fractal curves, which are formed by replacing each line segment in an initial figure with multiple interconnected parts, then substituting each of those parts with the same pattern of segments, then repeating the process an infinite number of times for every line segment in the figure.
Another example of a teragon is the horned triangle which is formed by pitching a series of smaller triangles on one corner of an equilateral triangle. It is also an example of a reptile, or shape that can be completely examined into smaller copies of itself.

What is System of Linear EquationA system of linear equations is a collection of two or more linear equations that use the same set of variables. The solution of the system is the set of values for the variables that satisfy all of the equations in the system.
To solve this problem, we have to set our variables as;
Let;
x = number of candiesy = number of flowersThe equations can be written as;
5x + 6y = 500 ...eq(i)
x + y = 200 ...eq(ii)
From equation ii,
x = 200 - y ...eq(iii)
Put eq(iii) into eq(i)
5(200 - y) + 6y = 500
1000 - 5y + 6y = 500
1000 + y = 500
y = -500
Put y = -500 into eq(ii)
x - 500 = 200
x = 700

8. On a map of scale 1:20 000 the area of a forest is 50 cm². On another map the area of the forest is 8 cm². Find the scale of the second map.
Answer: The scale of a map is a ratio that represents the relationship between distances on the map and distances in the real world. For example, a scale of 1:20 000 means that 1 unit on the map represents 20 000 units in the real world.
In this case, we are given that the area of the forest on the first map is 50 cm² and the area of the forest on the second map is 8 cm². We can use the scale of the first map to find the scale of the second map.
Since the area of the forest on the first map is 50 cm² and the scale is 1:20 000, the area of the forest in the real world is 50 cm² * 20 000 = 1 000 000 cm².
Similarly, since the area of the forest on the second map is 8 cm², the area of the forest in the real world is 8 cm² * x, where x is the scale of the second map.
Setting these two expressions equal to each other, we get:
1 000 000 cm² = 8 cm² * x
Dividing both sides of the equation by 8 cm², we get:
x = 125 000
Therefore, the scale of the second map is 1:125 000.

Emily's piggy bank contains twice as many dimes as nickels. It contains two more quarters than nickels. Emily calculates that if instead of the money she actually has, she has as many quarters as she has nickels, as many dimes as she has quarters, and as many nickels as she has dimes, then she would have $1,50 less than she actually has. How many nickels, how many dimes, and how many quarters are actually in Emily's piggy bank? Please no links
Answer:
Emily has 10 nickels, 20 dimes and 12 quarters in her piggy bank
Step-by-step explanation:
The number of dimes in Emily's piggy bank = 2 × The number of nickels
The number of quarters in it = 2 + The number of nickels
Whereby;
The number of quarters = The number nickels
The number of dimes = The number of quarters
The number of nickels = The number of dimes
The total amount = Current amount - $150
Let 'x' represent the number of dimes, let 'y' represent the number nickels, and let 'z' represent the number quarters in Emily's piggy bank, we have;
x = 2 × y
z = 2 + y
The total amount in the piggy bank is therefore;
Total = C = x×0.1 + y×0.05 + z×0.25 = 2·y×0.1 + y × 0.05 + (2 + y) × 0.25 = 0.5·y + 0.5
C = 0.5·y + 0.5
With the second condition, we have;
z = y
x = z
y = x
We get
x × 0.1 + y × 0.05 + z × 0.25 = y ×0.1 + y×0.05 + y×0.25 = 0.4·y = C - 1.5
∴ C = 0.4·y + 1.5
Which gives;
0.5·y + 0.5 = 0.4·y + 1.5
0.1·y = 1.5 - 0.5 = 1
y = 1/0.1 = 10
y = 10
Therefore;
x = 2×y = 2 × 10 = 20
z = 2 + y = 2 + 10 = 12
Therefore;
The number number of nickels in her piggy bank, y = 10
The number of dimes in her piggy bank, x = 20
The number of quarters in her piggy bank, z = 12
Answer:
24 nickles 48 dimes 26 quarters
