The amount each boy receives from the R2100 is R420, R700 and R980 respectively
How to find ratioTotal amount = R2100
Ratio = 3 : 5 : 7
Total ratio = 3 + 5 + 7
= 15
First boy = 3/15 × 2100
= 0.2 × 2100
= R420
Second boy = 5/15 × 2100
= 0.33333333333333 × 2100
= R700
Third boy = 7/15 × 2100
= 0.46666666666666 × 2100
= R980

A coordinate grid is shown from positive 8 to negative 8 on the x axis and from positive 8 to negative 8 on the y axis. An image of a rectangle labeled E is shown on ordered pair negative 1, negative 1 and negative 3, negative 1 and negative 3, negative 2 and negative 1, negative 2. Another image of a rectangle labeled G is shown on ordered pair negative 2, negative 2 and negative 6, negative 2 and negative 6, negative 4 and negative 2, negative 4. Another image of a rectangle labeled F is shown on ordered pair negative 1, 1 and negative 1, 2, and negative 3, 2 and negative 3, 1.
Which of the following statements is true about the three quadrilaterals?
E and F are similar but not congruent.
E and G are similar but not congruent.
G and F are similar and also congruent.
E and G are similar and also congruent.
Answer:
(a) A and B are similar but not congruent
Step-by-step explanation:
All of the rectangles have sides in the ratio of 2:1, so are all similar. Only the rectangles that are the same size are congruent: A and C.

A TV screen has a diagonal length of 156cm, the angle in the top corner is 37◦. Calculate the height of the TV screen
The TV screen is an illustration of a right triangle
The height of the TV screen is 124.6 cm
How to calculate the heightThe diagonal is given as:
d = 156 cm
The angle at the top is given as:
Angle = 37 degrees
The height is then calculated using the following cosine ratio
[tex]\cos(37) = \frac h{156}[/tex]
Make h the subject
[tex]h = 156 * \cos(37)[/tex]
Evaluate
h = 124.6
Hence, the height of the TV screen is 124.6 cm

5. Show that the following points are collinear. a) (1, 2), (4, 5), (8,9)
Label the points A,B,C
A = (1,2)B = (4,5)C = (8,9)Let's find the distance from A to B, aka find the length of segment AB.
We use the distance formula.
[tex]A = (x_1,y_1) = (1,2) \text{ and } B = (x_2, y_2) = (4,5)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(1-4)^2 + (2-5)^2}\\\\d = \sqrt{(-3)^2 + (-3)^2}\\\\d = \sqrt{9 + 9}\\\\d = \sqrt{18}\\\\d = \sqrt{9*2}\\\\d = \sqrt{9}*\sqrt{2}\\\\d = 3\sqrt{2}\\\\[/tex]
Segment AB is exactly [tex]3\sqrt{2}[/tex] units long.
Now let's find the distance from B to C
[tex]B = (x_1,y_1) = (4,5) \text{ and } C = (x_2, y_2) = (8,9)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(4-8)^2 + (5-9)^2}\\\\d = \sqrt{(-4)^2 + (-4)^2}\\\\d = \sqrt{16 + 16}\\\\d = \sqrt{32}\\\\d = \sqrt{16*2}\\\\d = \sqrt{16}*\sqrt{2}\\\\d = 4\sqrt{2}\\\\[/tex]
Segment BC is exactly [tex]4\sqrt{2}[/tex] units long.
Adding these segments gives
[tex]AB+BC = 3\sqrt{2}+4\sqrt{2} = 7\sqrt{2}[/tex]
----------------------
Now if A,B,C are collinear then AB+BC should get the length of AC.
AB+BC = AC
Let's calculate the distance from A to C
[tex]A = (x_1,y_1) = (1,2) \text{ and } C = (x_2, y_2) = (8,9)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(1-8)^2 + (2-9)^2}\\\\d = \sqrt{(-7)^2 + (-7)^2}\\\\d = \sqrt{49 + 49}\\\\d = \sqrt{98}\\\\d = \sqrt{49*2}\\\\d = \sqrt{49}*\sqrt{2}\\\\d = 7\sqrt{2}\\\\[/tex]
AC is exactly [tex]7\sqrt{2}[/tex] units long.
Therefore, we've shown that AB+BC = AC is a true equation.
This proves that A,B,C are collinear.

Which pair of functions are inverses of each other?
Answer:
B
Step-by-step explanation:
As you can see if the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions.
The pair of functions that are inverses of each other will be f(x) = 10x - 5. g(x) = x - 5/10. so option B is correct.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output. Inverse means that the function is reversed from the original function, f(x).
A: The original function, f(x) = x/8 + 3. g(x) = 8x - 3. they are not inverse functions.
B: The original function, f(x) = 10x - 5. g(x) = x - 5/10. they are inverse functions.
C: The original function, f(x) = 4/x - 3. g(x) = 1/x + 3/ 4, they are not inverse functions.
Hence, the pair of functions that are inverses of each other will be f(x) = 10x - 5. g(x) = x - 5/10. so option B is correct.
