20/05/2019. Calculate what percentage the withdrawal fee is of the
transaction amount. Calculate the percentage of R5000. 00
The withdrawal fee of R100.00 is 2% of the transaction amount of R5,000.00.
To calculate the percentage that the withdrawal fee is of the transaction amount, we need to determine the fee amount and then express it as a percentage of the transaction amount.
Let's assume that the withdrawal fee is 2% of the transaction amount. To calculate the fee amount, we multiply the transaction amount by the fee percentage:
Fee Amount = 2% of R5,000.00
= 0.02 * R5,000.00
= R100.00
Therefore, the withdrawal fee is R100.00.
To calculate the percentage of R5000.00, we can divide the fee amount by the transaction amount and then multiply by 100 to express it as a percentage:
Percentage = (Fee Amount / Transaction Amount) * 100
= (R100.00 / R5000.00) * 100
= 2%
Hence, the withdrawal fee of R100.00 is 2% of the transaction amount of R5,000.00.

The expression (y to the power of 20)(y to the power of −5)2i s equivalent to yn. What is the value of n?20010-20030
the value of n remains indeterminate in this case.To find the value of n in the expression (y^20)(y^-5)^2i equivalent to yn, we can simplify the expression first.
Starting with (y^20)(y^-5)^2i, we can simplify the exponent by multiplying the exponents of y:
(y^20)(y^-5)^2i = y^(20 + (-5 * 2))i = y^(20 + (-10))i = y^10i.
Now, we can equate this simplified expression to yn:
y^10i = yn.
To find the value of n, we can compare the exponents:
10i = n.
Since the imaginary unit i represents the square root of -1, and the exponent in this case is not purely real, we cannot find a specific value for n. Therefore, the value of n remains indeterminate in this case.

The length of a rectangle is represented by 2n+8, and its width is represented by n-7. Write the polynomial for the perimeter of the rectangle. Write your answer in standard form.
The polynomial for the perimeter of the rectangle can be expressed as P(n) = 2(2n+8) + 2(n-7), which simplifies to P(n) = 4n + 16 + 2n - 14.
Combining like terms, we get P(n) = 6n + 2. Therefore, the polynomial in standard form for the perimeter of the rectangle is P(n) = 6n + 2.
To find the perimeter of the rectangle, we need to add up the lengths of all four sides. The length of the rectangle is represented by 2n+8, so we have 2 sides of length (2n+8). The width of the rectangle is represented by n-7, so we have 2 sides of length (n-7). To calculate the perimeter, we add up the lengths of all four sides: (2n+8) + (2n+8) + (n-7) + (n-7).

The spheres cost $2 per square foot and Selim can spend $20 per sphere. What is the maximum diameter of the spheres he can purchase?
The surface area of a sphere is 4πr2, where r is the radius of the sphere. The cost of a sphere is 2 per square foot, so the cost of a sphere with radius r is 8πr2. Selim can spend 20 per sphere, so he can purchase a sphere with radius r such that 8πr2≤20. This inequality can be solved for r to get r≤8π20=2π5. The diameter of a sphere is 2r, so the maximum diameter of the spheres Selim can purchase is 22π5=10π≈3.162 feet.

How do you find the hight of the equation v=pi*r^2*h/3
The formula of height h = (3v) / (π * r^2)To find the height (h) of a cone given the volume (v) and the radius of the base (r), we can rearrange the equation v = (π * r^2 * h) / 3.
By multiplying both sides by 3 and dividing by π * r^2, we isolate the variable h and obtain the formula h = (3v) / (π * r^2). Substituting the appropriate values for volume and radius into this equation allows us to calculate the height of the cone.
To solve for the height (h) in the equation v = (π * r^2 * h) / 3, we first multiply both sides by 3 to eliminate the fraction. This results in the equation 3v = π * r^2 * h. Next, we isolate the variable h by dividing both sides of the equation by π * r^2, giving us the formula h = (3v) / (π * r^2). By substituting the known values for volume (v) and radius (r) into this equation, we can calculate the height (h) of the cone. It is important to ensure that the units for volume and radius are consistent and compatible to obtain the correct result.

There are three paths through a triangular park. Each path connects the midpoint of one side to the opposite corner. The paths meet at point P, which is the centroid
Find PS and PC when SC = 24000 feet
PS and PC are both equal to 16000 feet when SC is 24000 feet. These lengths are determined based on the relationship between the centroid and the midpoints of the sides in a triangle.
In a triangular park, with point P as the centroid, if SC (one of the sides) is equal to 24000 feet, the lengths of PS and PC can be determined.
To find the lengths of PS and PC, we need to consider the properties of a centroid in a triangle. The centroid divides each median into two segments, with the ratio of 2:1.
In other words, the distance from the centroid to the midpoint of a side is two-thirds of the length of the entire median.
In this case, since SC is equal to 24000 feet, PS and PC can be calculated as follows:
PS = (2/3) * SC = (2/3) * 24000 = 16000 feet.
PC = (2/3) * SC = (2/3) * 24000 = 16000 feet.

a blueprint of a house is drawn using a scale of 1/4 in = 3ft. If the bedroom of the actual house is 16 by 12 in, what are the dimensions of the bedroom of the blueprint
The dimensions of the bedroom in the blueprint are approximately 1/9 ft by 1/12 ft.
To find the dimensions of the bedroom in the blueprint, we can use the given scale of 1/4 in = 3 ft.
First, let's convert the dimensions of the actual bedroom into feet:
Length of the actual bedroom = 16 in * (1 ft / 12 in) = 16/12 ft = 4/3 ft
Width of the actual bedroom = 12 in * (1 ft / 12 in) = 12/12 ft = 1 ft
Now, let's use the scale to find the dimensions of the bedroom in the blueprint:
Length of the bedroom in the blueprint = Length of the actual bedroom * Scale
Length of the bedroom in the blueprint = (4/3 ft) * (1/4 in / 3 ft)
Length of the bedroom in the blueprint = 4/3 * 1/12
Length of the bedroom in the blueprint = 4/36
Length of the bedroom in the blueprint = 1/9 ft
Width of the bedroom in the blueprint = Width of the actual bedroom * Scale
Width of the bedroom in the blueprint = (1 ft) * (1/4 in / 3 ft)
Width of the bedroom in the blueprint = 1 * 1/12
Width of the bedroom in the blueprint = 1/12 ft

Suppose a chemist combines a 25% acid solution and a 50% acid solution to make 40 L of 45% acid solution. How many liters of each solution did she use? Use the blanks below to fill in your numerical answers.
__________ L of 50% solution; __________ L of 25% solution
To create a 40 L solution with a 45% acid concentration, a chemist combines a 25% acid solution and a 50% acid solution. Therefore, the chemist used 32 L of the 50% acid solution and (40 - 32) = 8 L of the 25% acid solution to create the 40 L solution with a 45% acid concentration.
Let's assume the chemist uses "x" liters of the 50% acid solution. Since the total volume of the mixture is 40 L, the remaining volume will be (40 - x) liters of the 25% acid solution.
The acid content in the 50% solution is 0.5x, while the acid content in the 25% solution is 0.25(40 - x).
To find the acid content in the final 45% solution, we multiply the acid concentration (0.45) by the total volume (40):
0.45 * 40 = 0.5x + 0.25(40 - x)
Simplifying the equation:
18 = 0.5x + 10 - 0.25x
Combining like terms:
0.25x = 8
Dividing both sides by 0.25:
x = 32
Therefore, the chemist used 32 L of the 50% acid solution and (40 - 32) = 8 L of the 25% acid solution to create the 40 L solution with a 45% acid concentration.

At sea level, the air presses down on our bodies at 14.7
pounds per square inch (psi). When diving in the ocean,
the pressure increases. The equation y = 0.445x + 14.7,
where x is the number of feet a diver descends, represents
this situation.
a. Explain using the definition how you know the
relationship represented by the equation is a function.
We can conclude that the relationship represented by the given equation is a function. Moreover, the pressure increases as the diver descends below sea level, which is shown by the positive slope (0.445) of the equation.
The equation y = 0.445x + 14.7 represents a situation where a diver descends below sea level. This equation gives the pressure (y) of the water at a depth of x feet below sea level. Here, y is dependent on x. It means that the pressure at a given depth is dependent on that particular depth. Therefore, we can say that the given equation represents a function because for each value of x, there is only one corresponding value of y.
A function is defined as a relation that maps each input value (x) to exactly one output value (y). In other words, it is a set of ordered pairs (x, y), where each value of x is paired with a unique value of y. The equation given above satisfies this definition of a function because it represents a one-to-one relationship between the depth (x) and the pressure (y) of the water.
Therefore, we can conclude that the relationship represented by the given equation is a function. Moreover, the pressure increases as the diver descends below sea level, which is shown by the positive slope (0.445) of the equation.
