1. Painted on a wall are 4 red triangles, 2 blue triangles, 6 green triangles and 8 yellow triangles. What percentage of the triangles are blue or red?


Jawaban:

red : 20%

blue : 10%

Penjelasan dengan langkah-langkah:

4+2+6+8=20

red : 4/20=2/10=20%

blue : 2/20=1/10=10%

semoga membantu.

Penjelasan dengan langkah-langkah:

4 merah

2 biru

6 hijau

8 kuning

berjumlah = 20 segitiga

segitiga biru dan merah = 4+2 = 6

20 = 100%

1 = (100/20)%

1 = 5%

presentase segitiga biru dan merah :

= (5×6)%

= 30%

3. 10. Let A = {right-angled triangles). (a) Is each of the following triangles an element of A? Explain your answer. (i) triangle with sides 3 cm, 4 cm and 5 cm (ii) triangle with sides 2 cm, 2 cm and 3 cm (b) Can each of the following sets be the universal set for the set A? Explain your answer. (i) U = {all triangles} (ii) V = {all polygons}​


Problem9

Let

[tex] \xi = \{x \colon x \text{ is an integer and } -3 \le x \le 3 \} \\ [/tex]

[tex] A = \{x \colon 2x + 1 < 5 \} \\ [/tex]

[tex] B = \left \{ x \colon \frac{x}{3} \text{ is an integer} \right \} \\ [/tex]

(a) Express the set [tex] A [/tex] by listing its elements.

(b) Is [tex] -4 [/tex] an element of [tex] A [/tex]? Explainyour answer.

(c)Write down the common elements of [tex] A [/tex] and [tex] B [/tex].

Solution

For part (a), the set of [tex] A [/tex] can be written as

[tex] A = \{-5, -3, -1, 1, 3 \} [/tex]

For part (b), [tex] -4 [/tex] is not an element of a set of [tex] A [/tex] because [tex] A [/tex] is a set of odd numbers with [tex] x \in [-3, 1], x \in \mathbb{Z} [/tex].

For part (c), both sets can be written as

[tex] A = \{-5, -3, -1, 1, 3\} [/tex]

[tex] B = \{-1, 0, 1\} [/tex]
