Mr. Jones in Johannesburg is billed R9,767.12 and Ms. Brown in Cape Town is billed R680.24 for their respective properties.
From the provided information for Cape Town's sanitation tariffs:
0-4.2 kl: R16.03 per kl
Since 4.1 ke is equivalent to 4100 liters, which is less than 4.2 kl, we can use the tariff rate for the 0-4.2 kl range.
Cost for 4.1 ke of sanitation
= 4.1 ke x R16.03 per kl
= 4100 liters x R16.03 per kl
= R65.83
For Mr. Jones and Ms. Brown, who own properties with an area of 550 m² each and were billed for 22 kl of sanitation.
we need to determine the applicable tariff rate based on the property size and calculate the cost.
In Johannesburg, based on the provided information, the tariff rate for properties larger than 300 m² to 1,000 m² is R443.96.
Cost of sanitation for Mr. Jones in Johannesburg:
= 22 kl x R443.96 per kl
= R9,767.12
Cost of sanitation for Ms. Brown in Cape Town:
= 22 kl x R30.92 per kl = R680.24
Therefore, Mr. Jones in Johannesburg is billed R9,767.12 and Ms. Brown in Cape Town is billed R680.24 for their respective properties.

1.2 If Erin had 150m/ of buttermilk and recipe require 0.25 cups of buttermilk, would Erin have enough buttermilk for the recipe (2) 1.3 A cake recipe calls for 0.8 kg of flower, 650g of sugar and 900 000mg of butter. 1.3.1 Determine the total mass of the ingredients. Give you answer in kilograms. (2) 1.3.2 If sugar comes in 150g bags at cost of R5.95 per 150g, determine the total cost of the (2) sugar needed for this recipe.
If Erin had 150m/ of buttermilk and recipe require 0.25 cups of buttermilk, she has more than the required amount, so she has sufficient buttermilk for the recipe.
1.2 To determine if Erin has enough buttermilk for the recipe, we need to convert the given quantities to a common unit.
150 ml of buttermilk is equivalent to 0.15 liters (since 1 liter = 1000 ml).
Now, let's convert 0.25 cups to liters. Since 1 cup is approximately 0.2366 liters, we have:
0.25 cups ≈ 0.25 * 0.2366 liters = 0.05915 liters.
Comparing the amount of buttermilk Erin has (0.15 liters) with the amount required by the recipe (0.05915 liters), we can see that Erin has enough buttermilk. She has more than the required amount, so she has sufficient buttermilk for the recipe.
1.3.1 To determine the total mass of the ingredients, we need to convert the given quantities to a common unit, kilograms.
0.8 kg of flour is already in kilograms.
650 g of sugar is equivalent to 0.65 kg (since 1 kg = 1000 g).
900,000 mg of butter is equivalent to 900 g (since 1 g = 1000 mg), which is 0.9 kg.
Adding up the masses of the ingredients:
0.8 kg (flour) + 0.65 kg (sugar) + 0.9 kg (butter) = 2.35 kg.
Therefore, the total mass of the ingredients is 2.35 kilograms.
1.3.2 If sugar comes in 150 g bags at a cost of R5.95 per 150 g, we can calculate the total cost of the sugar needed for the recipe.
The recipe requires 650 g of sugar. Since each bag contains 150 g of sugar, we divide the required amount by 150 g:
650 g / 150 g = 4.3333 bags.
Since we cannot purchase a fraction of a bag, we need to round up to the nearest whole number. So, we'll need to buy 5 bags of sugar.
The total cost of the sugar is calculated by multiplying the number of bags by the cost per bag:
5 bags * 5.95 per bag = 29.75.
Therefore, the total cost of the sugar needed for the recipe is 29.75.

Question 6 Which of the following is the graph of f(x) = x² = 5x + 4?
Given: The equation x² = 5x + 4
We have to draw the the graph for the given equation.
Consider the given equation,
x^2 - 5x - 4 = 0
The vertex of the parabola of the form f(x) = ax^2 + bx + c is given by x = -b/2a
Here,
a= 1
b= -5
c= -4
vertex = x = 5/2= 2.5
Also, the y coordinate at x = 2.5 is,
y = (2.5)^2 -5(2.5)-4
y = -10.25
Thus the vertex of parabola is (2.5 , -10.25)
y - intercept is the point where x = 0
put x = 0 in given equation
f(x) = 0 - 0 -4
f(x) = -4
hence y intercept is at (0, -4).
Now, we calculate x- intercept
x- intercept is where y is equal to 0.
Put f(x) = 0
We have,
x^2 - 5x - 4 = 0
by using quadratic formula,
x = -b ±√b² - 4ac/2a
x=5 ±√-5² - 4 (1)(-4)/2
x= 5±√41/2.

a margin of error of 3 inches. Describe this statement using an absolute
value equation.
By using this absolute value equation, the chef can determine the range of cake diameters that meet the desired margin of error of 3 inches and make an informed decision when purchasing the cake.
The absolute value of the difference between the actual diameter of the cake and the ideal diameter of 24 inches should be less than or equal to 3 inches.
To describe the statement using an absolute value equation, let's define the variable "d" as the actual diameter of the cake.
The ideal diameter of the cake is given as 24 inches.
The margin of error is specified as 3 inches, which means the chef is willing to accept a cake with a diameter within 3 inches of the ideal size.
Considering the margin of error, we can express the acceptable range of diameters for the cake as follows:
d - 24 ≤
This inequality states that the difference between the actual diameter "d" and the ideal diameter of 24 inches should be less than or equal to 3 inches, indicating that the actual diameter should be no more than 3 inches larger or smaller than 24 inches.
However, to represent this condition using an absolute value equation, we need to remove the inequality signs.
We can rewrite the inequality above using absolute value:
|d - 24| ≤ 3
This absolute value equation states that the absolute value of the difference between the actual diameter "d" and the ideal diameter of 24 inches should be less than or equal to 3 inches.
It encompasses both possibilities of the actual diameter being within 3 inches greater or smaller than 24 inches.
By using this absolute value equation, the chef can determine the range of cake diameters that meet the desired margin of error of 3 inches and make an informed decision when purchasing the cake.

feet 10 inches long. How long is the walkway?
Write your answer in feet and inches. Use a number less than 12 for inches.
C
The walkway is 12 feet 9 inches long.
To find the total length of the walkway, we need to add the lengths of the three boards together.
The first board is 3 feet 7 inches long, which can be written as 3'7".
The second board is 5 feet 4 inches long, which can be written as 5'4".
The third board is 3 feet 10 inches long, which can be written as 3'10".
Now, let's add the lengths together:
3'7" + 5'4" + 3'10"
When adding feet and inches, we need to carry over any extra inches beyond 12 to the feet.
Adding the inches first:
7" + 4" + 10" = 21"

Yes, the product of X and Y, that is X × Y is a set.
Given that, the product X×Y is a set because X×Y⊂PP(X∪Y).
A set is defined as a collection of elements or members, and X × Y meets this criteria as it is a collection of ordered pairs of elements from X and Y.
We can also prove this using set theory. The expression X × Y⊂PP(X∪Y) means that the set X × Y is a subset of the power set of the union of X and Y.
The power set of a set A is a set of all subsets of A, which means that PP(X∪Y) includes all of the possible combinations of the elements from X and Y.

In circle D, m∠EDF=70∘, and the length of EF=[tex]\frac{14}{9} \pi[/tex]. Find the length of DE.
To find the length of DE in circle D, we can use the properties of a circle and the given information.
In a circle, if two chords intersect, the product of the segments of one chord is equal to the product of the segments of the other chord. In this case, we have chord EF intersecting chord DE at point D.
Let x represent the length of segment DE, and y represent the length of segment DF. Therefore, the length of segment EF would be (x + y).
According to the chord-chord power theorem:
DE * EF = DF * DF
Substituting the given values:
x * (x + y) = y * y
x^2 + xy = y^2
We are also given that angle EDF measures 70 degrees. According to the angle intercepting chord theorem, the intercepted arc EF is twice the measure of angle EDF. So, the measure of arc EF is 2 * 70 = 140 degrees.
Now, we can use the length of arc EF to find the ratio of the lengths of segments EF and DF.
The ratio of the lengths of the intercepted arcs is equal to the ratio of the lengths of the corresponding chords. Therefore:
EF / DF = arc EF / arc DF
(x + y) / y = 140 / 360 [Using the measure of the intercepted arcs]
Simplifying this equation:
(x + y) / y = 7 / 18
Cross-multiplying:
18(x + y) = 7y
18x + 18y = 7y
18x = 7y - 18y
18x = -11y
Dividing by -11:
x = -11y / 18
We need to find the value of x, which represents the length of segment DE. Since segment lengths cannot be negative, we can disregard the negative sign.
x = 11y / 18
Substituting this value of x in the equation x^2 + xy = y^2:
(11y / 18)^2 + (11y / 18) * y = y^2
Simplifying:
121y^2 / 324 + 11y^2 / 18 = y^2
Multiplying through by 324:
121y^2 + 594y^2 = 324y^2
715y^2 = 324y^2
715y^2 - 324y^2 = 0
391y^2 = 0
y^2 = 0
Since y^2 = 0, it implies that y = 0. This means that segment DF has zero length.
Now, substituting y = 0 into the equation x = 11y / 18:
x = 11 * 0 / 18
x = 0
Therefore, the length of DE is 0.
In conclusion, the length of DE is 0.

25 * 1 + 29 * 1 + 31 * 2 + 33 * 4 + 35 * 5 + 37 * 8 + 39 * 4
= 875
And, Frequency = 1 + 1 + 2 + 4 + 5 + 8 + 4 = 25
Hence,
Mean = 875/25
Mean = 35
For Southview
25 * 2 + 27 * 6 + 29 * 9 + 31 * 6 + 33 * 2
= 725
Frequency = 2 + 6 + 9 + 6 + 2 =25
Hence, Mean = 29
So, from our calculation, the mean of East Hills HS is greater than the mean of Southview HS.

Chapter
2^5• (−2) – 4 •5+7
The numeric value of the expression in this problem is given as follows:
-77.
How to obtain the numeric value of the expression?The expression in the context of this problem is defined as follows:
[tex]2^5[/tex] x (-2) - 4 x 5 + 7.
Considering the PEMDAS acronym, the power operation has the precedence over the remaining operations, hence:
[tex]2^5[/tex] x (-2) - 4 x 5 + 7 = 32 x (-2) - 4 x 5 + 7.
Then, following the same acronym, we have that the multiplication operation has precedence over the addition/subtraction operations, hence:
32 x (-2) - 4 x 5 + 7 = -64 - 20 + 7.
Finally, we can just subtract and add the numbers to obtain the numeric value of the expression as follows:
-64 - 20 + 7 = -77.
