Item
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:
Sale Price =Original Price multiplied by (1 - Discount)
Sale Price = $94.00 x (1 - 35%) = $61.10

Find the slope of the line passing through each of the following pairs of points (-6,-5) (-4,-3)
The Slope of the line is 1.
The slope of a line:The slope of a line is a numerical value that shows the stiffness or direction of the line. The formula used to find the Slope of the line is given by
Slope (m) = [ y₂ - y₁] / [ x₂ - x₁]Where (x₁, y₁) and (x₂, y₂) are pairs of points that pass through the line.
Here we have
The pair of points (-6, -5) and (-4, -3)
By using the formula,
The slope of the line = [ y₂ - y₁] / [ x₂ - x₁]

What is the vertical asymptote and horizontal asymptote pic attached below
The required horizontal and vertical asymptote is x = 2, -2, and y = 1/4.
How to find Asymptotes?To find the vertical asymptotes of the given rational function, we need to look for values of x that make the denominator zero, since division by zero is undefined.
The denominator of the function is 4(x-2)(x+2), so the vertical asymptotes occur at x = 2 and x = -2. Therefore, the vertical asymptotes are:
x = 2, -2
To find the horizontal asymptote, we can use the fact that as x goes to positive or negative infinity, the function approaches the ratio of the leading coefficients of the numerator and denominator.
In this case, the leading term in the numerator is x² and the leading term in the denominator is 4x². Therefore, as x approaches positive or negative infinity, the function approaches:
y = (x² / 4x²) = 1/4
So, the horizontal asymptote is:
y = 1/4

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.

if S is 150% of T, then T is what percent of S+T
The percentage representation of T as part of S + T as required is; 40 percent.
What is the percentage representation of T as part of S + T?As evident in the task content;
S is 150% of T.
S = 150/100 × T
S = 1.5T.
Therefore, expressing T as a percentage of S + T as required is as follows;
= (T / (S + T)) × 100%
substitute S = 1.5T into the equation
= T / (T + 1.5T) × 100%
= (1/2.5) × 100%
= 0.4 × 100%
= 40%.
Ultimately, the variable T is 40 percent of S + T.

Step-by-step explanation:
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.

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

The IQ score given the mean and the standard deviation, can be found to be 105. 25.
How to find the IQ score ?To find the indicated IQ score corresponding to a right tail area of 0.3694, we can use a standard normal distribution table or calculator. Using a calculator, we can find that the z-score corresponding to a right tail area of 0.3694 is approximately 0.35.
Once we have the z-score, we can use the formula z = (x - μ) / σ to solve for the IQ score :
0.35 = (x - 100) / 15
Solving for x, we get:
x = 0.35 x 15 + 100

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.
