Based on the expression, Mr. Mbhalati's prediction is correct. His water bill will decrease in Polokwane.

Let's calculate Mr. Mbhalati's water bill in Polokwane and Tzaneen.

Polokwane

Monthly use: 50 kl

Rate: R15.10/kl

Total bill: 50 kl * R15.10/kl

= R755

Tzaneen

Monthly use: 50 kl

Rate: R23.70/kl

Total bill: 50 kl * R23.70/kl

= R1185

As you can see, Mr. Mbhalati's water bill will decrease in Polokwane. His bill in Tzaneen is R430 more than his bill in Polokwane.

Therefore, Mr. Mbhalati's prediction is correct. His water bill will decrease in Polokwane.

The necessary condition for ordered pairs (a,b) is that the following characterizing property of them can be proved; (a,b)=(c,d)

And if and only if a=c and b=d

Since we can prove that

{{a},{a,b}}={{c},{c,d}} if and only if a=c and b=d

Thus defining (a,b)  as an abbreviation for {{a},{a,b}} suffices for ordered pairs.

We can also consider that

The surface area of the rectangular prism given the length, width and height is 1800 square cm.

Surface area of a rectangular prism = 2(LW + LH + WH)

Where,

Length, L = 40 cm

Width, W = 10 cm

Height, H = 10 cm

Surface area of a rectangular prism = 2(LW + LH + WH)

= 2(40×10 + 40×10 + 10×10)

= 2(400 + 400 + 100)

The value of r is 5 cm.

Given that, a right triangle has a base of r cm and hypotenuse of 10 cm with an angle 60 degrees we need to find the value of r,

The trigonometric function cosine (cos) can be used to determine the value of the right triangle's base (r).

We are aware of the hypotenuse (10 cm) and angle (60 degrees) in this situation.

The ratio of a right triangle's neighboring side to hypotenuse is known as the cosine function.

The base (r) in this instance is the opposite side, and the hypotenuse measures 10 cm.

Using the formula for cosine:

cos(angle) = adjacent/hypotenuse

cos(60 degrees) = r/10

60 degrees has a cosine of 0.5.

So,

0.5 = r/10

To solve for r, we can multiply both sides of the equation by 10:

0.5 x 10 = r

5 = r

Therefore, the value of r is 5 cm.

Answer:

Step-by-step explanation:

Image (2) is 4x every measurement of image (1).

The area (A) of the trapezoid is 225 square kilometers.

The area of Figure #12 is 144 square centimeters.

Question 1:

To find the area (A) of a trapezoid, we can use the formula:

A = (1/2) x (a + b) x h

where 'a' and 'b' are the lengths of the parallel bases and 'h' is the height or the perpendicular distance between the bases.

Given:

Length of the parallel bases:

a = 11 km

b = 19 km

Length of the other two sides:

c = 17 km

d = 15 km

To find the height (h), we can use the Pythagorean theorem since the trapezoid is not necessarily a right trapezoid.

Let's consider the right triangle formed by the height (h), one of the other sides (c = 17 km), and the difference in lengths between the parallel bases (b - a = 19 km - 11 km = 8 km).

Using the Pythagorean theorem:

h² = c² - (b - a)²

h² = 17² - 8²

h² = 289 - 64

h² = 225

h = √225

h = 15 km

Now we have all the values to calculate the area (A):

A = (1/2) x (11 km + 19 km) x 15 km

A = (1/2) x 30 km x 15 km

A = 225 km²

Therefore, the area (A) of the trapezoid is 225 square kilometers.

Question 2:

The area of Figure #12 can be described as.

A  = (6 x 18) + (3 x 12)

A = 108 + 36 square centimeters

A = 144 square centimeters.

Step-by-step explanation:

To calculate the number of 18-inch by 24-inch cake pans needed, we need to determine how many 3-inch by 3-inch portions can be cut from each pan.

First, we need to find the area of the cake pan:

Area of one cake pan = Length × Width = 18 inches × 24 inches = 432 square inches.

Next, we need to find the area of one portion of cake:

Area of one portion = Length × Width = 3 inches × 3 inches = 9 square inches.

Now we can calculate how many portions of cake can be cut from one cake pan:

Number of portions per pan = Area of one cake pan / Area of one portion = 432 square inches / 9 square inches = 48 portions.

Since each pan can yield 48 portions of cake, we can divide the total number of attendees by the number of portions per pan to find the number of pans needed:

Number of pans needed = Total number of attendees / Number of portions per pan = 210 people / 48 portions = 4.375.

Since we cannot have a fraction of a cake pan, we need to round up to the nearest whole number. Therefore, the club will need 5 (or more precisely, 5 pans and some extra portions) of the 18-inch by 24-inch cake pans to serve each person one portion of cake.

According the given figure, angle Z is calculated using interesting secants and tangents to be

50 degrees

To find angle Z we follow the following procedures

first find angle he central angle

central angle = 180 - 2 * 25

central angle = 180 - 50

central angle = 130

Secondly

central angle is equal to the minor arc

Then using interesting secants and tangents

Angle Z = 1/2(major arc - minor arc)

major arc = 360 - 130 = 230

Angle Z = 1/2(230 - 130)

Angle Z = 1/2(100)

The height of the ladder to the top of the building is 14.4 feet.

The ladder leaned against the building. The base of the ladder is 12 ft from the base of the building. Marta is 6 feet tall.

Therefore, let's find how far up the building is the top of the ladder.

Hence, using similar triangle ratios,

x / 12 = 6 / 5

where

x = height of the building from the top of the ladder.

Therefore,

x / 12 = 6 / 5

cross multiply

5x = 72

The correct equation of the circle with center (0,0) that passes through the point (-6,-6) is:

(x + 6)² + (y + 6)² = 72

Please note that the equation represents the circle with center (0,0) and radius √72.[tex][/tex]

Answer:

The equation of a circle with center (0,0) that passes through the point (-6,-6) is:

(x - 0)² + (y - 0)² = r²

where r is the radius of the circle. Since the center of the circle is (0,0), we can use the distance formula to find the radius:

r = √(0 - (-6))² + (0 - (-6))² = √(6² + 6²) = √72

Therefore, the equation of the circle is:

Area of rectangle is,

A = 45 units²

And, Perimeter of rectangle is,

⇒ P = 28 units

We have to given that;

Vertices of rectangle are,

⇒ (- 4, - 5)  

⇒ (-4, 0)

⇒ (5, 0)

⇒ (5, - 5)

Since, The distance between two points (x₁ , y₁) and (x₂, y₂) is,

⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²

Hence, Length of rectangle is distance between (- 4, - 5) and (- 4, 0).

Which is,

⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²

⇒ d = √ (- 4 + 4)² + (0 + 5)²

⇒ d = √ 25

⇒ d = 5

And,  Width of rectangle is distance between (- 4, 0) and (5, 0).

Which is,

⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²

⇒ d = √ (- 4 - 5)² + (0 - 0)²

⇒ d = √ 81

⇒ d = 9

Thus, Area of rectangle is,

A = L x W

A = 5 x 9

A = 45 units²

And, Perimeter of rectangle is,

⇒ P = 2 (L + W)

⇒ P = 2 (5 + 9)

Total amount John has to pay = [tex]\$3 + (\$5.25 * X[/tex])

To determine the equation that represents the total amount John has to pay for tax, we need to consider the cost of the watermelon and the cost of the grapes he purchased.

The cost of the watermelon is $3, which remains constant regardless of the weight of the grapes.

The cost of the grapes is given as $5.25 per pound. Multiplying the price per pound by the number of pounds (X), we get the cost of the grapes:

Cost of grapes = $5.25 * X

To find the total amount John has to pay, including tax, we need to add the cost of the watermelon and the cost of the grapes:

Total amount John has to pay = Cost of watermelon + Cost of grapes

Total amount John has to pay =[tex]\$3 + (\$5.25 * X)[/tex]

Therefore, the equation that represents the total amount John has to pay for tax is:

Total amount John has to pay = [tex]\$3 + (\$5.25 * X)[/tex]

The simplified equation shows that the total amount John has to pay for the grapes depends on the cost per pound ($5.25), the tax rate (t), and the weight of the grapes (x).

-4 * 3^(n-1)

Step-by-step explanation:

The rule for a geometric sequence is given by the formula an = a1 * r^(n-1), where a1 is the first term, r is the common ratio, and n is the term number. To find the common ratio, we can use the formula r = a2/a1 = a3/a2, since any two consecutive terms in a geometric sequence have the same ratio.

Given that a3 = -12 and r = 3, we can solve for a1 as follows:

a3 = a1 * r^(3-1)

-12 = a1 * 3^2

a1 = -4

Let's set u = 2^t:Substituting u = 2^t, the equation becomes:u^2 - 12u + 32 = 0Now we have a quadratic equation in terms of u. We can solve it by factoring or using the quadratic formula. Let's try factoring:(u - 4)(u - 8) = 0Setting each factor equal to zero, we have:u - 4 = 0 or u - 8 = 0Solving for u:u = 4 or u = 8Now, substitute back u = 2^t:For u = 4:

2^t = 4Taking the logarithm base 2 of both sides:

t = log2(4)

t = 2For u = 8:

2^t = 8Taking the logarithm base 2 of both sides:
