Step-by-step explanation:
Ana's conjecture that Raul lost 2/5 of his baby teeth is true.
To see why, consider that Raul originally had 20 baby teeth. If he lost 8 of these teeth, that means he has 20 - 8 = 12 baby teeth remaining. To determine what fraction of his baby teeth he lost, we can calculate:
8 baby teeth lost / 20 baby teeth total = 2/5
So, Raul lost 2/5 of his baby teeth, which supports Ana's conjecture.
On the other hand, Raul's statement that he lost 4/10 of his baby teeth is not correct, since 4/10 can be simplified to 2/5, which is the same as Ana's conjecture that he lost 2/5 of his baby teeth.

What is the area of a square that has a perimeter of thirty two centimetres?
Answer:
Step-by-step explanation:
I got you
So,
The perimeter of a square is the sum of the lengths of all its sides, and since a square has all sides equal, we can find the length of one side by dividing the perimeter by 4:
32 cm ÷ 4 = 8 cm
Therefore, each side of the square measures 8 centimeters. To find the area of the square, we can use the formula:
Area = side length x side length
So, the area of the square is:
Area = 8 cm x 8 cm = 64 square centimeters
Therefore, the area of the square with a perimeter of 32 centimeters is 64 square centimeters.
Use the percent formula, A=PB: A is P percent of B, to answer the following question. 20% of what number is 46.0?
Answer:
230
Step-by-step explanation:
trying to find (in this case, 46.0), P is the percentage (20%), and B is the whole amount we're looking for. We can write this equation as:
46.0 = 0.20B
To solve for B, we can divide both sides by 0.20:
B = 46.0 / 0.20
B = 230
Therefore, 20% of 230 is 46.0.

Problem 2. You are looking to purchase a new luxury Dsports car at a price of $93,500. You negotiate a six-year loan, with no money down and no monthly payments during the first year. After the first year, you will pay $1,300 per month for the following five years, with a balloon payment at the end to cover the remaining principal on the loan. The APR on the loan with monthly compounding is 5%. What will be the amount of the balloon payment six years from now?
So the balloon payment six years from now will be approximately $24,612.09.
What factors determine interest rates?(P, R, and T) / 100 is the SI unit.
In this case, SI stands for Straightforward Interest. P is the initial investment or loan amount, and R is the interest rate.
To find the amount of the balloon payment six years from now, we can use the formula for the present value of a series of payments:
PV = PMT x (1 - (1 + r/n)^(-nt)) / (r/n)
where PV is the present value of the payments, PMT is the monthly payment, 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 total number of years for the loan.
In this case, we have:
PMT = $1,300 (paid for 5 years)
r = 0.05 (5% APR)
n = 12 (monthly compounding)
t = 6 (total loan term, including the first year with no payments)
To calculate the present value of the payments, we first need to find the present value of the $93,500 loan, one year from now, when the payments begin. This is equivalent to finding the future value of the loan now, and then discounting it back one year using the interest rate.
The future value of the loan after one year is:
FV = $93,500 x (1 + r)¹ = $98,175.00
The present value of this future amount, discounted back one year at an interest rate of 5%, is:
PV = $98,175.00 / (1 + r)¹ = $93,500.
So the present value of the loan one year from now, when the payments begin, is approximately $93,500.
Using this present value as the principal amount for the remaining 5 years of payments, we can calculate the balloon payment using the present value formula above:
PV = PMT x (1 - (1 + r/n)^(-nt)) / (r/n)
PV = $1,300 x (1 - (1 + 0.05/12)⁻⁶⁰) / (0.05/12)
PV = $68,887.91
Therefore, the balloon payment six years from now will be the remaining principal on the loan after five years of payments, which is:
Balloon payment = $93,500 - $68,887.91 = $24,612.09.
So the balloon payment six years from now will be approximately $24,612.09.

Describe Recursive Formula?A recursive formula is a formula or equation that describes a sequence or function in terms of itself. In other words, the formula for a given term or value depends on the formula for one or more previous terms or values.
For example, the Fibonacci sequence is a sequence of numbers in which each term is the sum of the two preceding terms: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, ...
This sequence can be described recursively using the following formula:
F(n) = F(n-1) + F(n-2)
where F(n) is the nth term of the sequence, F(n-1) is the (n-1)th term, and F(n-2) is the (n-2)th term.
Another example of a recursive formula is the factorial function, which is defined for non-negative integers n as:
n! = n * (n-1)!
This formula states that the factorial of n is equal to n multiplied by the factorial of (n-1). This recursive definition can be used to compute the factorial of any non-negative integer.

Original Price Discount Sale Price
Soccer Jersey $85.75 20% $ ?
Tennis Racket $ ? 55% $49.05
Archery Set $94.00 % ? $61.10
Thus, the archery set's discounted price is $61.10.
What does discount mean?A reduction from the normal or list price. providing clients with a 10% discount. purchasing discounted tickets. (2): a proportionate reduction from an account of debt, typically provided in exchange for cash or quick payment.
The initial cost of the soccer jersey must be multiplied by (100% - 20%) = 80%, or 0.8, to determine the sale price after a 20% discount.
$85.75 x 0.8 = $68.60; Sale Price =Original Price multiplied by (1 - Discount)
Hence, the soccer jersey's retail price is $68.60.
We can apply the formula to get the tennis racket's original cost after just a 55% reduction and a $49.05 sale price:
Original Cost = Discounted Cost (1 - Discount)
Original Price = $49.05 / (1 - 55%) = $49.05 / 0.45 = $109.00
Hence, the tennis racket's original cost is $99.00.
The following formula can be used to determine the discount % for the archer set with just an original cost of $94.00 as well as a sale of $61.10:
Discount = (Original Price - Sale Price) / Original Price x 100%
Discount = ($94.00 - $61.10) / $94.00 x 100% = 35%
Hence, the archery set has a 35% discount.
The following equation can be used to determine the retail price of a archery kit with a 35% reduction and an original cost of $94.00:

A 50kg mass is shot from a cannon straight up with an initial velocity of 10m/s off a bridge that is 100 meters above the ground. If air resistance is given by 5v, determine the velocity of the mass when it hits the ground.
Answer:
To set up this problem, you have to begin with Newton's second law, F = ma. There are two forces acting on this mass, gravity and air resistance. The force of gravity is constant and equal to -mg, where g = 9.8 m/s^2 and m is the given mass.
Step-by-step explanation:
Answer:
the velocity of the mass when it hits the ground is approximately 58.4 m/s.
Step-by-step explanation:
We can solve this problem using the equations of motion for a particle under constant acceleration. The acceleration of the particle is the sum of the gravitational acceleration and the air resistance force, which is given by 5v:
a = -g + 5v/m
where g is the acceleration due to gravity (9.8 m/s^2) and m is the mass of the particle (50 kg).
Using the initial conditions, we can find the velocity of the particle as a function of time. At t=0 (when the particle is shot from the cannon), the initial velocity is 10 m/s, and the initial position is 100 m above the ground. Therefore, we have:
v(0) = 10 m/s
y(0) = 100 m
Using the equation of motion for the position of the particle, we have:
y = y(0) + v(0)t + (1/2)at^2
where y is the position of the particle as a function of time t.
Solving for t when the particle hits the ground (y=0), we get:
0 = 100 + 10t + (1/2)(-g+5v/m)t^2
Simplifying, we get a quadratic equation in t:
-gt^2/2 + (5v/m)t + 100 = 0
Solving for t using the quadratic formula, we get:
t = (-b ± sqrt(b^2 - 4ac))/2a
where a = -g/2, b = 5v/m, and c = 100. Using the positive solution (since we're interested in the time it takes for the particle to hit the ground), we get:
t = (-5v/m + sqrt((5v/m)^2 + 4g100))/(-g)
Simplifying, we get:
t = (-5v/m + sqrt((5v/m)^2 + 3920))/(-4.9)
Now we can use the equation of motion for the velocity of the particle to find the velocity when it hits the ground:
v = v(0) + at
Substituting the time t we just found and solving for v, we get:
v = 10 + (-g + 5v/m)t
Substituting the value of t we just found and solving for v, we get:
v = 10 + (-g + 5v/m)(-5v/m + sqrt((5v/m)^2 + 3920))/4.9
Simplifying and solving for v, we get:
v ≈ 58.4 m/s
Therefore, the velocity of the mass when it hits the ground is approximately 58.4 m/s.

Write a polynomial P(x), in factored form given the following requirements
• Degree: 3
• Leading coeffcient: 1
• x-intercepts at (10,0) and (−1,0)
• y-intercept at (0,−40)
Answer:
The polynomial in factored form is:
P(x) = (x-10)(x+1)(x+1)
or, we can write it in expanded form as:
P(x) = x^3 - 8x^2 - 11x + 40.
Step-by-step explanation:
If the x-intercepts are at (10,0) and (-1,0), then the polynomial must have factors of (x-10) and (x+1). If the y-intercept is at (0,-40), then the constant term must be -40.
To satisfy the given requirements, we can write the polynomial as:
P(x) = (x-10)(x+1)(x-a)
where a is a constant that we need to determine. To find a, we can use the fact that the leading coefficient is 1.
Expanding the expression above, we get:
P(x) = (x^2 - 9x - 10)(x-a)
= x^3 - ax^2 - 9x^2 + 9ax - 10x + 10a
= x^3 - (a+9)x^2 + (9a-10)x + 10a
Since the leading coefficient is 1, we know that the coefficient of x^3 is 1. Therefore, we must have:
1 = 1*(-a-9)*(9a-10)
Simplifying and solving for a, we get:
a = -1
Therefore, the polynomial in factored form is:
P(x) = (x-10)(x+1)(x+1)
or, we can write it in expanded form as:
P(x) = x^3 - 8x^2 - 11x + 40.
2 Tom argues that his PAYE for the following year will increase by R593.09. The following year Tom's salary increases by 8.5%. How much tax will Tom pay per year, if he still contributes only 7.5% of his gross salary to a pension fund but increases his contribution to the charity organization by further R50.00 a month? Calculate as if the tax table for the following year remains the same.
Tom's total annual tax for the following year, assuming the tax table remains the same, is R325,287.17.
How much tax will Tom pay per year?To calculate Tom's tax for the following year, we need to first calculate his current monthly PAYE (Pay As You Earn) deduction. We can use the current tax table to do this.
Tom's gross salary is R25,780.25 per month, and he is 45 years old, so according to the 2021/2022 tax table for individuals under 65 years old, his monthly PAYE deduction is:
= R1,458.75 + 25% of the amount over R14,958
= R4,569.96
Tom argues that his PAYE will increase by R593.09 for the following year. This means that his expected monthly PAYE deduction for the following year is:
= R4,569.96 + R593.09
= R5,163.05
Tom's salary for the following year will increase by 8.5%, so his new gross salary will be:
= R25,780.25 + (8.5% x R25,780.25)
= R27,959.83
Tom's pension fund contribution remains the same at 7.5% of his gross salary:
= R27,959.83 x 7.5%
= R2,097.49
His charity organization contribution increases by R50.00 per month:
= R50.00 x 12
= R600.00
Assuming the tax table remains the same as the previous year, Tom's new monthly PAYE deduction is:
= R1,577.98 + 26% of the amount over R17,708
= R5,502.86
To calculate Tom's total annual tax, we need to subtract his annual PAYE deduction from his gross salary and then add back his pension and charity contributions:
Total annual tax = (R27,959.83 x 12) - (R5,502.86 x 12) + R2,097.49 + R600.00
Total annual tax = R325,287.17.

How do I solve this and what’s the answer?
he three data sets have the same mean and range, but is the variation the same? Prove your answer by computing the standard deviation. Assume the data were obtained from samples. (a) 4, 5, 11, 13, 13, 14 (b) 5, 7, 10, 10, 13, 15 (c) 3, 10, 11, 11, 12, 13
The standard deviations of the data are different.
Standard deviation:
The formula used to calculate the standard deviation of data is given by
Standard deviation = √[ ∑(x[tex]_{i}[/tex] - x)² /n ]x - mean of the data and n = number of observations
Here we have
(a) 4, 5, 11, 13, 13, 14
Mean of the data = [4 + 5 + 11 + 13 + 13 + 14 ]/6 = 60/6 = 10
On calculating deviations
=> ∑(x[tex]_{i}[/tex] - x)² = 96
=> √[ ∑(x[tex]_{i}[/tex] - x)²/n ] = √[ 96/ 6 ] = 4
(b) 5, 7, 10, 10, 13, 15
Since the mean of the data is equal for all
On calculating deviations
=> ∑(x[tex]_{i}[/tex] - x)² = 68
=> √[ ∑(x[tex]_{i}[/tex] - x)² /n ] = √[ 68/ 6 ] = 3.36
(c) 3, 10, 11, 11, 12, 13
On calculating deviations
=> ∑(x[tex]_{i}[/tex] - x)² = 64
=> √[ ∑(x[tex]_{i}[/tex] - x)² /n ] = √[ 64/ 6 ] = 3.26
Therefore,
The standard deviations of the data are different.
