Answer: The square is inscribed in a circle that means the square is drawn inside a circle such that it's vertices lie on the circle.

You need to remember that the vertices of the square lie on the circumference of circle and the center of circle is also the midpoint of diagonals of the square i.e. Diagonal of the square is equal to diameter of the circle.

We could also see the image of such figure.

It can be estimated that the total amount of water that Mr. Thando used is 40 Kiloliters. See the arithmetic calculation/ explanation below and the reconstructed table attached.

The approximate amount of water that he has been charged for will be given as follows:

The maximum fee for Band A + Maximum fee for Band B + Maximum fee for Band C.

Which is: (0) + (6.36 *14) + (7.98*20) = R248.64

Recall that the total amount he was charged is R281.27.

Hence, because the question does not include the percentage of VAT payable, and the referenced table is unavailable, we are forced to assume that the difference between the amount paid and our calculations above is the VAT.

This figure (that VAT)  is: R281.27 - R248.64 = R32.63

Hence, the total amount of water used by Mr. Thando is: 6 + 14 + 20 = 40Kl

Answer:

little falls has more

Step-by-step explanation:

show your work: little falls total rainfall is 1 6/8 and riverside is 1 5/8

use that to explain :) your welcome

Answer:

  Riverside had the greatest rainfall total

Step-by-step explanation:

The total amount of rain in a city will be the sum of products of rain amount and days that got that amount. The city with the largest sum got the most rain. The difference in rainfall can be found by subtracting the lesser amount from the greater.

__

Total rainfall in Riverside was ...

  (1/8)×1 +(2/8)×3 +(3/8)×3 +(4/8)×1 +(5/8)×1

  = (1 +6 +9 +4 +5)/8 = 25/8 = 3 1/8 . . . . inches

__

Total rainfall in Little Falls was ...

  (1/8)×1 +(3/8)×1 +(4/8)×1 +(6/8)×2

  = (1 +3 +4 +12)/8 = 20/8 = 2 1/2 . . . . inches

__

Riverside had more rainfall, because 3 1/8 is more than 2 1/2.

__

You can "cancel" dots that are in the same place on each plot. Doing so leaves Riverside with 3 dots at 2/8, 2 dots at 3/8, and 1 dot at 5/8. The remaining dots on the Little Falls plot are the 2 dots at 6/8.

The 3 dots at 2/8 add up to 6/8, as do the 2 dots at 3/8 on the Riverside plot. These two 6/8 values cancel the two 6/8 dots on the Little Falls plot. That leaves one uncancelled dot at 5/8 on the Riverside plot, indicating more rain fell at Riverside.

The chords ac and db are intersecting chords, and the length of line segment db is 16 units

The given parameters are:

ah = 20 - x

hb = 12 - x

dh = x + 4

hc = x

Start by calculating the value of x using the following intersection chord equation

ah * hc = dh * hb

So, we have:

(20 - x) * x = (x + 4) * (12 - x)

Solve for x

x = 4

The length of segment db is calculated using:

db = dh + hb

So, we have:

db = x + 4 + 12 - x

Substitute 4 for x

db = 4 + 4 + 12 - 4

Evaluate

db = 16

Hence, the length of line segment db is 16 units

Step-by-step explanation:

If the height of the trapezium is 7 units. Then the area of the trapezium will be 31.5 square units.

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a trapezium, one pair of opposite sides are parallel.

The quadrilateral ABCD whose vertices are A(-2,-1), B(-2,-3), C( 5,6), and D(5,-1).

The lines AB and CD are parallel to the y-axis. Then the quadrilateral ABCD is a trapezium.

The height of the trapezium will be 7 units.

The area of the trapezium will be

Area = 1/2 (2 + 7) x 7

Area = 0.5 x 9 x 7

Area = 31.5 square units.

Step-by-step explanation:

Simplify the expression such that the variable has a positive exponent.

Substitute x = 7.

Answer:

W'' (-5,-11) , X'' (-11,-9) , Y'' (-9,-3) and Z'' (-3,-5)

Kindly check the attached image for more reference

Step-by-step explanation:

Given points of WXYZ ( can be identified by looking at the graph )

Applying translation 3 units left , 15 units down

(Note when shifting left , you subtract from the x value , when shifting down, you subtract from the y value.)

Rule for translation (x,y) ===> ( x - 3 , y - 15 )

Applying translation to given points

Applying rotation 270° counterclockwise around the origin

Rotation 270° clockwise rule : (x,y) ===> (y,-x)

Explanation of rule , change the sign of the x values, then swap the x and y values places.

Applying rotation rule to points

So the final points of square WXYZ after the two transformations would be W'' (-5,-11) , X'' (-11,-9) , Y'' (-9,-3) and Z'' (-3,-5)

To see this graphed, kindly view the attached image.

The red square represents the square before any transformations

The blue square represents the square following the translation

And the black square represents the coordinates of the square after the full transformation including both the translation and the rotation .

Answer:

Original image:

W = (14, 10)

X = (12, 4)

Y = (6, 6)

Z = (8, 12)

To translate 3 units left, subtract 3 from the x-values (x - 3)

To translate 15 units down, subtract 15 from the y-values (y - 15)

W' = (14 - 3, 10 - 15) = (11, -5)

X' = (12 - 3, 4 - 15) = (9, -11)

Y' = (6 - 3, 6 - 15) = (3, -9)

Z' = (8 - 3, 12 - 15) = (5, -3)

(red square on attachment)

To rotate 270° counterclockwise around the origin (0, 0),

the point (x, y) becomes (y, -x). So, switch x and y and make x negative.

W'' = (-5, -11)

X'' = (-11, -9)

Y'' = (-9, -3)

Z'' = (-3, -5)
