Answer:
1a. 58/99
1b. 53/90
1c. 29/50
Step-by-step explanation:
let's start with the easiest one
1.(c)
0.58 = 58/100 = 29/50
that is the simplest possible form, as 29 is a prime number and not a factor of 50.
1.(a)
0.585858585858... = 58×0.0101010101010101...
now, we know that 1/"double digit" (like 1/22) mostly produces a repeating pattern with a period length of 2 after the decimal point.
and we find
1/99 = 0.01010101010101...
so, our solution is
58 × 1/99 = 58/99
that is the simplest possible form, as 58 and 99 do not share any factors.
1.(b)
0.5888888888888... = 0.5 + 0.0888888888888... =
= 0.5 + 8×0.01111111111111... = 0.5 + 8×1/10 × 0.1111111111...
we know how to create 0.11111111111... :
1/9 = 0.111111111111111...
so, our solution is
0.5 + 8 × 1/10 × 1/9 = 0.5 + 8/90 = 5/10 + 8/90 =
= 45/90 + 8/90 = 53/90
this is the simplest possible form, as 53 is already a prime number and not a factor of 90.

the first are 2 parallel lines. they never cross, so there is no solution at all.
and the second one is seemingly only one line. well a line goes on infinitely, and every point on it is a solution to the line equation. so, this has infinite many solutions.

Um cant figure out the second question
Answers
Answer:
£15
Step-by-step explanation:
There are 3 ways to get 7 out of the 12 possible outcomes, so the probability a player will win 30p is 1/4. That is a player will have expected winnings of (1/4)(30p) = 7.5p each time the game is played.
The school gains 20p from each player, but has an expected payout to the player of 7.5p, so the net gain per game to the school is ...
20p -7.5p = 12.5p
The gain to the school when 120 people play is ...
(120)(12.5p) = 1500p = £15 . . . . expected to be raised

Answer:
I'm going to do 1 as an example and using what I've taught you, you have to do the rest. Hope my explanation helps.
Step-by-step explanation:
We are given the points (-2, -4) and (-1, -1)
We need to find the slope.
The equation to do so is y2 - y1 / x2 - x1
lest say:
-2 is x1
-4 is y1
-1 is x2
-1 is y2
-1 - (-4) / -1 - (-2)
3/1 = 3
slope (m) = 3
We already know the y-intercept is 2
The equation of a line is y = mx + b
For this problem we just have to substitute what we already know.
y = (slope)x + y-intercept
y = 3x + 2
*TIP*
If the y-intercept is negative, let's say: b = -5 (using slope 8)
the equation will be y = 8x - 5
Hope this helps. I wish you all the best. :)

2x² + 3 = 39 extracring square roots
Answers
Answer:
x=9
Step-by-step explanation:
first, subtract 3 from both sides so 2x^2=36, then, divide both sides by 2 so x^2=18 and divide 18 by 2 and 9^2=18
Answer:
x = ± 3[tex]\sqrt{2}[/tex]
Step-by-step explanation:
2x² + 3 = 39 ( subtract 3 from both sides )
2x² = 36 ( divide both sides by 2 )
x² = 18 ( take square root of both sides )
x = ± [tex]\sqrt{18}[/tex] = ± [tex]\sqrt{9(2)}[/tex] = ± ( [tex]\sqrt{9}[/tex] × [tex]\sqrt{2}[/tex] ) = ± 3[tex]\sqrt{2}[/tex]

Answer:
For ∆1 , x = 20 , y = 10√2
For ∆2 , x = y = 11
Step-by-step explanation:
Here in the first right angled triangle one of the angles is 45°. And one of the known side is 20 . We need to find out the value of x and y.
Since two angles are 90° and 45° , therefore the third angle will be 45° . And as we know that the sides opposite to equal angles are equal. Therefore ,[tex]\rm\longrightarrow \underline{\underline{ x =20}}[/tex]
Again , we use ratio of sine to find y , as ,
[tex]\rm\longrightarrow sin45^o =\dfrac{p}{b}\\ [/tex]
[tex]\rm\longrightarrow \dfrac{1}{\sqrt2}=\dfrac{20}{y}\\ [/tex]
[tex]\rm\longrightarrow y =\dfrac{20}{\sqrt2}=\dfrac{2\times 10}{\sqrt2}\\ [/tex]
[tex]\rm\longrightarrow \underline{\underline{ y = 10\sqrt2}} [/tex]
[tex]\qquad\rule{200}2[/tex]
Again , in the second Triangle , we may use ratio of sine to find the value of y , as ;
[tex]\rm\longrightarrow sin45^o =\dfrac{p}{b}\\ [/tex]
[tex]\rm\longrightarrow \dfrac{1}{\sqrt2}=\dfrac{y}{11\sqrt2}\\ [/tex]
[tex]\rm\longrightarrow y =\dfrac{11\sqrt2}{\sqrt2}\\ [/tex]
[tex]\rm\longrightarrow \underline{\underline{ y = 11}} [/tex]
Again , we know that the sides opposite to equal angles are equal . Therefore here ,[tex]\rm\longrightarrow \underline{\underline{ x =11}}[/tex]
