Khadija went to the store to buy some apples. The price per pound of the apples is $7.50 per pound and she has a coupon for $1.75 off the final amount. With the coupon, how much would Khadija have to pay to buy 4 pounds of apples? Also, write an expression for the cost to buy
Answers
The final cost of 4 pounds is $28.25 and the final cost of p pounds is $4.
Expression for the cost to buy is, Cost(x) = $7.50x - $1.75
What is the cost price?The cost price is the price from which the seller buys the product. An expression simply consists of one or more numbers that are along the operation that is given.
In this case, the price per pound of the apples is $7.50 per pound and he has a coupon for $1.75 off the final amount.
The amount to amount that Khajida has to pay to buy 4 pounds of apples will be:
7.50p - 1.75 =
where P = number of pounds
p = 4
This will be:
5.50p - 2.5
7.5(4) - 1.75
27.5 - 1.75
28.25
The amount paid is $28.25.
Therefore, the final cost of 4 pounds: $28.25.
The final cost of p pounds: 4 dollars
To write an expression for the cost to buy x pounds of apples with the coupon, we can use the formula:
Cost = price per pound * number of pounds - coupon amount
Using this formula, we can write:
Cost(x) = $7.50x - $1.75
Where x represents the number of pounds of apples Khadija wants to buy.

Answers
The best height he can jump is 2.5 meters. The solution has been obtained by using the arithmetic operations.
What are arithmetic operations?
It is believed that the four fundamental operations, often known as "arithmetic operations," adequately explain all real numbers. Division, multiplication, addition, and subtraction are the mathematical operations that come before quotient, product, sum, and difference.
We are given that Ivan Ukhov jumps 2.4 metres which is 4% lower than the best height he can jump.
Let the best height be 'x'.
So, from the above information, we get
⇒ x - 0.04x = 2.4
⇒ 0.96x = 2.4 (Using subtraction)
⇒ x = 2.5 (Using division)
Hence, the best height he can jump is 2.5 meters.

The limit of the determinant as [tex]t[/tex] approaches 0 is [tex]-\infty[/tex].
To evaluate this limit, we can use the fact that the determinant is a linear function of each row, and that the limit of a sum is the sum of the limits. Therefore, we can compute the limit of each row separately.
Starting with the first row, we have:
[tex]\lim_{t\to 0} \int_0^t \frac{u}{\sinh(u)} du
= \lim_{t\to 0} \frac{\int_0^t \frac{u}{\sinh(u)} du}{t} \cdot t
= \lim_{t\to 0} \frac{\frac{t}{\sinh(t)} - 1}{t} \cdot t
= \lim_{t\to 0} \frac{1-\sinh(t)}{t\sinh(t)} = 1[/tex]
[tex]\lim_{t\to 0} \cos(t)
= 1[/tex]
[tex]\lim_{t\to 0} \sum_{n=1}^{\infty} \frac{1}{n+t+i}
= \sum_{n=1}^{\infty} \lim_{t\to 0} \frac{1}{n+t+i}
= \sum_{n=1}^{\infty} \frac{1}{n+i}
= \psi(i+1) \approx 0.643 + 0.41i[/tex]
where [tex]\psi(z)[/tex] is the digamma function.
Therefore, the limit of the first row is [tex]1 \cdot 1 \cdot \psi(i+1) = \psi(i+1)[/tex].
Moving on to the second row, we have:
[tex]\lim_{t\to 0} \frac{d}{dt} \left(e^t \ln \left(\frac{1}{t}\right) \right)
= \lim_{t\to 0} \frac{e^t}{t} - \lim_{t\to 0} \frac{e^t}{t^2}
= 1 - \infty = -\infty[/tex]
[tex]\lim_{t\to 0} \binom{5}{2} t^2
= 0[/tex]
[tex]\lim_{t\to 0} \prod_{n=1}^4 \left(\sqrt{1+nt} - 1\right)
= \prod_{n=1}^4 \lim_{t\to 0} \left(\sqrt{1+nt} - 1\right)
= \prod_{n=1}^4 \sqrt{1+n} - 1
= 4\sqrt{2} - 5[/tex]
Therefore, the limit of the second row is [tex]-\infty \cdot 0 \cdot (4\sqrt{2} - 5) = 0[/tex].
Finally, for the third row, we have:
[tex]\lim_{t\to 0} i\binom{5}{3} t^3 \sin(2t) = 0[/tex]
[tex]\lim_{t\to 0} \sum_{n=1}^{5} n^2 e^{int}
= \sum_{n=1}^{5} n^2 \lim_{t\to 0} e^{int}
= \sum_{n=1}^{5} n^2
= 55[/tex]
[tex]\lim_{t\to 0} \binom{8}{2} t^2 + i\binom{5}{2} t^3 \cos(3t) = 28[/tex]
Therefore, the limit of the third row is [tex]0 \cdot 55 \cdot 28 = 0[/tex].
Putting everything together, we get:
[tex]\lim_{t\to 0} \det\left(\begin{bmatrix} \displaystyle \int_0^t \frac{u}{\sinh(u)} du & \cos(t) & \displaystyle \sum_{n=1}^{\infty} \frac{1}{n+t+i} \\ \displaystyle \frac{d}{dt} \left(e^t \ln \left(\frac{1}{t}\right) \right)
& \binom{5}{2} t^2 & \displaystyle \prod_{n=1}^4 \left(\sqrt{1+nt} - 1\right) \\ i\binom{5}{3} t^3 \sin(2t) & \displaystyle \sum_{n=1}^{5} n^2 e^{int} & \binom{8}{2} t^2 + i\binom{5}{2} t^3 \cos(3t) \end{bmatrix}\right) = \det\left(\begin{bmatrix} \psi(i+1) & 1 & 0 \\ -\infty & 0 & 4\sqrt{2}-5 \\ 0 & 55 & 28 \end{bmatrix}\right) = -\infty[/tex]

Suppose that Mars rotates on its axis once every hours. The equator lies on a circle with a diameter of miles.
(a) Find the angular speed of a point on its equator in radians per day ( hours).
(b) Find the linear speed of a point on the equator in miles per day.
Do not round any intermediate computations, and round your answer to the nearest whole number.
Answers
The answer of the given question based on the Angular speed is (a) the angular speed of a point on Mars' equator is π/2 radians per day. (b) the linear speed of a point on the equator of Mars is approximately 889.33 miles per day.
What is Linear speed?Linear speed, also known as tangential speed, is the distance traveled by an object in a straight line per unit of time. It is the speed at which an object is moving along its path, tangent to the path at any given point. Linear speed is calculated by dividing the distance traveled by the time taken to travel that distance. The units of linear speed are typically expressed in meters per second (m/s), miles per hour (mph), or kilometers per hour (km/h), depending on the system of measurement used.
(a) The angular speed of a point on Mars' equator is the angle (in radians) that a point on the equator sweeps out as Mars rotates on its axis. Since Mars completes one rotation every 24 hours, the angular speed is:
angular speed =(2πradians)/ (24 hours)= π/12radians per hour
To find the angular speed in radians per day, we need to multiply by the number of hours in a day:
angular speed = (π/12 radians per hour) * (24 hours per day) = π/2 radians per day
Therefore, the angular speed of a point on Mars' equator is π/2 radians per day.
(b) The linear speed of a point on the equator is the distance traveled by a point on the equator in a certain amount of time. The distance traveled by a point on the equator in one rotation is equal to the circumference of the circle with a diameter of miles, which is:
C = πd = π(6794) ≈ 21343.98 miles
Since Mars rotates once every 24 hours, a point on the equator travels the circumference of the circle in 24 hours. Therefore, the linear speed of a point on the equator in miles per day is:
v = C/24 ≈ 889.33 miles/day
So the linear speed of a point on the equator of Mars is approximately 889.33 miles per day.

Use the rules for multiplication and/or division of measurements. According to climatologists, the carbon dioxide (CO₂) levels in the atmosphere in 2012 were the highest levels in 650,000 years, standing at 396 parts per million (ppm). The safe upper limit is 350 ppm. The current rate of increase is 2.10 ppm per year. If that rate of increase remains constant from 2012 until 2030, what would be the expected CO₂ level (in ppm) in our atmosphere by the end of the year 2030? (Round your answer to the same number of significant digits as the measurement that has the least number of significant digits.) ppm
Answers
Rounding to the same number of significant digits as the measurement with the least number of significant digits (which is "350 ppm"), the expected CO₂ level by the end of 2030 would be 430 ppm.
Describe Significant digits?Significant digits, also known as significant figures or sig figs, are the digits in a number that are considered to be accurate or meaningful. They represent the precision or reliability of a measurement or calculation.
In a number, all digits except for leading zeros are considered to be significant. For example, in the number 0.00456, there are three significant digits (4, 5, and 6), while the zeros before the 4 are not significant.
The rules for determining the number of significant digits in a number are:
All non-zero digits are significant.
Zeros between non-zero digits are significant.
Leading zeros are not significant.
To find the expected CO₂ level in the atmosphere by the end of 2030, we need to calculate the total increase in CO₂ levels from 2012 to 2030 and then add it to the 2012 CO₂ level of 396 ppm.
To calculate the total increase in CO₂ levels, we can use the following formula:
Total increase in CO₂ levels = rate of increase × time
where the rate of increase is 2.10 ppm per year and the time is the number of years from 2012 to 2030, which is 18 years.
Total increase in CO₂ levels = 2.10 ppm/year × 18 years = 37.8 ppm
Therefore, the expected CO₂ level in the atmosphere by the end of 2030 would be:
Expected CO₂ level = 2012 CO₂ level + total increase in CO₂ levels
Expected CO₂ level = 396 ppm + 37.8 ppm
Expected CO₂ level = 433.8 ppm
Rounding to the same number of significant digits as the measurement with the least number of significant digits (which is "350 ppm"), the expected CO₂ level by the end of 2030 would be 430 ppm.

The rival football team is predicted to score 35 points at the next game. How many field
goals (3 points) and how many touchdowns (assume 7 points) does your team need to
score in order to win? Let f = field goal and t = touchdown. Create an inequality to
represent this situation and determine values for the variables in an organized way that
makes your inequality true. List at least 3 possible game winning combinations and
justify your answer.
Answers
To win the game, your team needs to score more than [tex]35[/tex] points, which means: 3f + 7t > 35 three possible game-winning combinations are:
[tex]t = 5, f = 11: 3(11) + 7(5) = 63[/tex]
[tex]t = 6, f = 8: 3(8) + 7(6) = 62[/tex]
[tex]t = 7, f = 5: 3(5) + 7(7) = 56[/tex]
Each of these combinations would result in your team scoring more than 35 points and winning the game.
What is equation?An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=).
For example, the argument [tex]"2x + 3 = 9"[/tex] asserts that the phrase [tex]"2x + 3"[/tex] equals the number "9." The purpose of equation solving is to determine the value or values of the variable(s) that allows the equation to be true.
Equations can be simple or complicated, regular or nonlinear, and include one or more elements. The variable x is raised to the second power in the equation. [tex]"x2 + 2x - 3 = 0."[/tex] Lines are utilised in many different areas of mathematics, such as algebra, calculus, and geometry.
Let's let f be the number of field goals scored by your team and t be the number of touchdowns scored by your team.
a) To win the game, your team needs to score more than 35 points, which means:
3f + 7t > 35
We can simplify this inequality by dividing both sides by 1:
3f + 7t/1 > 35/1
3f + 7t > 35
b) Now, we need to find possible values for f and t that make this inequality true. Since we are looking for positive integer values for f and t, we can start by testing different values for t and solving for f:
If t = 5, then 3f + 7(5) > 35, so 3f > 0 and f > 0. Possible solutions are f = 1, f = 2, f = 3, and so on.
If t = 6, then 3f + 7(6) > 35, so 3f > 7 and f > 2. Possible solutions are f = 3, f = 4, f = 5, and so on.
If t = 7, then 3f + 7(7) > 35, so 3f > 14 and f > 4. Possible solutions are f = 5, f = 6, f = 7, and so on.
c) So, three possible game-winning combinations are:
[tex]t = 5, f = 11: 3(11) + 7(5) = 63[/tex]
[tex]t = 6, f = 8: 3(8) + 7(6) = 62[/tex]
[tex]t = 7, f = 5: 3(5) + 7(7) = 56[/tex]

Calculate the come tax on salary of Birr 5200. Derive formule to calculate income tax and on Birr x, in terms of x. here x falls on the interval 5251 to 7800
Answers
the income tax payable on a salary of Birr 5200 is Birr 320.
In Ethiopia, income tax is calculated based on a progressive tax system where the tax rate increases as the taxable income increases. The formula for calculating income tax on monthly salary is as follows:
Taxable income = Gross monthly salary - Deductions
Tax payable = Tax rate * (Taxable income - Tax threshold) - Allowances
Where:
1. Gross monthly salary: Total salary before any deductions.
2. Deductions: Includes mandatory deductions such as employee social security contributions, pension contributions, and other authorized deductions.
3. Taxable income: Gross monthly salary minus deductions.
4. Tax rate: The percentage of tax applicable to the taxable income based on the tax bracket.
5. Tax threshold: The minimum amount of taxable income before tax is applicable.
6. Allowances: Includes authorized tax deductions such as dependant's allowance and other authorized allowances.
To calculate the income tax on a salary of Birr 5200, we need to determine the taxable income first. Let's assume that the gross monthly salary is Birr 5200, and there are no deductions.
Taxable income = Birr 5200 - 0 = Birr 5200
Next, we need to determine the tax rate applicable to this taxable income based on the tax bracket. For the taxable income range of Birr 5251 to 7800, the tax rate is 10%. Therefore, the tax rate applicable to Birr 5200 is 10%.
Tax rate = 10%
Now, we need to determine the tax threshold and the allowances applicable to this taxable income. Let's assume that the tax threshold is Birr 2000, and there are no allowances.
Tax threshold = Birr 2000
Allowances = 0
Using the formula mentioned earlier, we can calculate the income tax payable as follows:
Tax payable = 10% * (Birr 5200 - Birr 2000) - 0
Tax payable = Birr 320
Therefore, the income tax payable on a salary of Birr 5200 is Birr 320.
To derive the formula to calculate income tax on Birr x, we can use the same formula mentioned earlier. We can express the formula in terms of x as follows:
Taxable income = x - Deductions
Tax payable = Tax rate * (Taxable income - Tax threshold) - Allowances
Where:
1. x: Gross monthly salary.
2. Deductions: Includes mandatory deductions such as employee social security contributions, pension contributions, and other authorized deductions.
3. Taxable income: Gross monthly salary minus deductions.
4. Tax rate: The percentage of tax applicable to the taxable income based on the tax bracket.
5. Tax threshold: The minimum amount of taxable income before tax is applicable.
6. Allowances: Includes authorized tax deductions such as dependant's allowance and other authorized allowances.
We can use this formula to calculate the income tax payable on any salary falling within the Birr 5251 to 7800 taxable income range.
In conclusion, income tax in Ethiopia is calculated based on a progressive tax system, where the tax rate increases as the taxable income increases. To calculate income tax on a salary of Birr 5200, we need to determine the taxable income, tax rate, tax threshold, and allowances applicable to that salary. We can use the same formula to calculate income tax on any salary within the Birr 5251 to 7800 taxable income range.

A and B are two mathematically similar containers.
Container A has surface area of 1550mm2 and container B has surface area of 10478mm2 Given that
volume of container B − volume of container A = 62 160mm3
calculate the volume, in mm3 , of container A.
Answers
Answer: Let's call the scale factor between the two containers "k". Then, we know that the ratio of their surface areas is equal to the square of the scale factor:
(surface area of B) / (surface area of A) = k^2
We also know that the ratio of their volumes is equal to the cube of the scale factor:
(volume of B) / (volume of A) = k^3
We can rearrange the first equation to solve for k:
k^2 = (surface area of B) / (surface area of A) = 10478 mm^2 / 1550 mm^2 = 6.75
Taking the square root of both sides, we get:
k = sqrt(6.75) = 2.6 (rounded to one decimal place)
Now we can use the second equation to find the volume of container A:
(volume of B) - (volume of A) = 62160 mm^3
(k^3)(volume of A) - (volume of A) = 62160 mm^3
Simplifying and solving for the volume of A, we get:
volume of A = 62160 mm^3 / (k^3 - 1) = 62160 mm^3 / (2.6^3 - 1) ≈ 4477 mm^3

Write the arithmetic sum formula.
Answers
Using the arithmetic sequence formula we know that the 14 term of the given sequence is 41.
What is an arithmetic sequence?An arithmetic series is one that has the following formula: a, a + d, a + 2d, a + 3d, a + 4d,...
The common difference of the sequence is d, and the number an is the first term.
An arithmetic sequence's nth term is determined by the formula a = a + (n - 1)d.
So, we have the sequence:
2, 5, 8, 11, 14
Common difference = 5 - 2 = 3
Then, the formual is:
aₙ = a + (n - 1)d
Then, insert values:
aₙ = a + (n - 1)d
a₁₄ = 2 + (14 - 1)3
a₁₄ = 2 + (13)3
a₁₄ = 2 + 39
a₁₄ = 41
Therefore, using the arithmetic sequence formula we know that the 14 term of the given sequence is 41.

Please help with this equation I’ll give brainliest.
Answers
Step-by-step explanation:
a) Since the temperature of the oven is decreasing by a percentage of its current temperature each minute, the function that best represents this situation is an exponential function.
b) Let T be the temperature of the oven in degrees Fahrenheit at time x minutes after it was turned off. The initial temperature of the oven was 450° F, and the temperature decreases by 10% each minute. This can be expressed as:
T = 450(0.9)^x
Therefore, the function that models the situation is:
f(x) = 450(0.9)^x
where f(x) is the temperature of the oven in degrees Fahrenheit x minutes after it was turned off.

Answers
The volume of wax is required to make 1 candle is 22.92 cu. in.
Explain about the shape of cone:A cone is a tri solid geometric object with an apex that is pointed at the top and a circular base. A cone has a vertex and one face.
The length of a line segment from a cone's apex to any point along the circumference of a cone's base is known as the slant height of the cone.An oblique cone is one that doesn't have its apex directly over the base's circle.Given data:
Candle's shape is cone.height h = 6 in.circumference c = 12 inchesLet the radius of the cone be 'r'.
circumference c = 2*π*r
c = 2*π*r
12 = 2*3.14*r
r = 6/3.14
r = 1.91
Volume of cone V = 1/3 * π * r² *h

Jaime runs 8 miles every 3 days.
At this rate how long will it take
Jaime to run 96 miles?
Answers
Answer:
It will take Jaime 36 days to run 96 miles.
Step-by-step explanation:
The formula for rate is:
[tex]\boxed{\sf Rate=\dfrac{Distance}{Time}}[/tex]
Therefore, Jaime's run rate is:
[tex]\implies \sf Rate=\dfrac{8\;miles}{3\;days}=\dfrac{8}{3} \;miles\;per\;day[/tex]
Rearrange the rate formula to isolate time:
[tex]\implies \sf Time=\dfrac{Distance}{Rate}[/tex]
To find how long it will take for Jaime to run 96 miles, substitute the distance and rate into the formula and solve for time:
[tex]\implies \sf Time=\dfrac{96\;miles}{\frac{8 \;miles}{3\;days}}[/tex]
[tex]\implies \sf Time=96\;miles \times \dfrac{3\;days}{8\;miles}[/tex]
[tex]\implies \sf Time= \dfrac{288}{8}\;days[/tex]
[tex]\implies \sf Time= 36\;days[/tex]
Therefore, it will take Jaime 36 days to run 96 miles.
Identify the local, maximum and minimum for the function given
Answers
The function f(x) = 2x³-3x² - 12x + 1 does not have any local maximum or minimum values over the interval [2, 3].
EquationsTo find the local maximum and minimum of a function over a given interval, we need to find the critical points of the function within that interval and then apply the second derivative test to classify those critical points as local maximum or minimum.
To find the critical points, we first take the derivative of the given function:
f'(x) = 6x² - 6x - 12 = 6(x² - x - 2)
x = -1 or x = 2
Both of these critical points fall outside the given interval [2, 3]. Therefore, there are no critical points of the function within the interval [2, 3], and so there are no local maximum or minimum values of the function over this interval.
In other words, the function f(x) = 2x³-3x² - 12x + 1 does not have any local maximum or minimum values over the interval [2, 3].

Krysti is ordering T-shirts for 25 classmates. She knows that 80% of her class wants a small size she mistakingly ordered 12 small size t shirts
Answers
As 80 percentage of 25 classmates is equal to 20. Krysti should have ordered 20 small t-shirts for her 25 classmates
What is error?Error is when a mistake is made while solving a mathematical problem.
Krysti's error in finding the number of small t-shirts is that she forgot to multiply the percentage by the total number of classmates.
If Krysti wanted to find the number of small t-shirts she should have ordered, she should have multiplied
80% * 25.
=0.8 * 25
= 20.
To explain it in another way, Krysti could have also 100/25 and then 80 divided by the answer that is 4. This would also give the same result of 20.
Krysti's error was that she did not correctly use percentages to find the number of small t-shirts she should have ordered.

George invests a sum of money into a savings account with a fixed annual interest rate of 5.5% and compounded 6 times a year. After 7 years the account has a balance of $3,820. What is the initial investment?
Group of answer choices
a. $1506.30
b. $2603.88
c. $7082.77
d. $5604.10
Answers
The initial investment was approximately $2,603.88, which is option (b).
What is probability?Probability is a measure of the likelihood of an event occurring.
We can use the formula for compound interest:
A = [tex]P(1+r/n)^{nt}[/tex]
where A is the final amount, P is the principal (initial investment), r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the time period in years.
In this case, we know that the final amount A is $3,820, the annual interest rate r is 5.5% (or 0.055 as a decimal), the interest is compounded 6 times a year (n = 6), and the time period is 7 years.
So we can rearrange the formula to solve for P:
P = A/[tex]P(1+r/n)^{nt}[/tex]
Plugging in the values, we get:
P = 3820 / [tex](1+0.055/6)^{6*7}[/tex]
P ≈ $2,603.88
Therefore, the initial investment was approximately $2,603.88, which is option (b).
