how hard is this blah blah and how long?

its easy e.g
Q-1f(x)=2x + 3
a). f(2)
Ans: f(x)=2(2) + 3
=4+3
f(2) =7

Ratio of lengths is 1:3 so area is square that is 1:9.So PST is 1 and PQR is 9.Since the trapezium is the larger triangle minus the smaller one it will be 9-1=8.So their ratio will be 9:8

I need some help in this question

You just have to use the ratio here using the given data. Given that $25 becomes $62 after 8 years then;
25:500 = 62:X
X = (500*62)/25
X = $1240

(a) Bill is y years old
Ada is x years old
Last year Bill was 6x
Lets assume that Ada was 3 years old last year. Bill was 6(3) = 18
This year Ada will be 4 years old, and Bill will be 19.
Bill's age = 6(Ada's age) -5
19 = 6(4) -5
19=19
y=6x-5

(b) in 19 years time; Ada will be x+19, and Bill will be y + 19
They have stated that in 19 years time, Bill will be twice as old as Ada
2 (x+19) = y+19
SOLVE FOR y
y=2x+19

Thanks a lot bro !

Another Only the (c) part

Another Only the (c) part View attachment 38808

Its simple.
Form the eqn. of AB which is y-7=1/3 x
Solve it further
x=3y-21
x-3y+21=0

Therefore, P=-3 and Q=21

Can anyone explain the Paper 1 Q12 (c) answer to me? Here is the examiner report:
http://papers.xtremepapers.com/CIE/...D (Calculator Version) (4024)/4024_w03_er.pdf

 

[Ram97]

0.001 is 1/1000 which is 1/10^3
so 10^c = 1/10^3
10^c = 10^-3
same bases get cancelled
c=-3

Do some papers and see what you get
the final grade is higher in cie owing to percentile
dont worry

Never Underestimate yourself and also never Overestimate yourself (that means insan ka bacha ban, ajj nahi to kabhi nahi) focus on your studies my dear one
