© 2 = 360 / 12 =30 °
of a polygon A sector has are .
Area of sector =© / 360 × rot 8 ^2
= 150 / 360 ×22 / 7× 100 / 1
A =130 – 95 cm^2

2 b )
1 /2 ( 2x + 1 ) – 2 /5 ( x – 2 )= 3
2 x +1/ 3 – 2 x – 4/ 3= 3
10 x +5 – 6x + 12 / 15 =3 / 1
Cross multiple
4 x +17 =45
4 x /4 =28 / 4
x = 7.

3 )
Apply 5m rule to find C P
t / sin T = P /sin P
t / sin 110 = 6/ sin 40
t =6 * 0. 9396 / 0. 6428
= 56376 / 6. 6428
= 87704
= 877 km

4 )
Total Fruit = 80 + 60 = 140
( a)
( i ) Pr one of each fruit is picked
( 79 / 140 * 60 / 139 ) + ( 59 / 140 * 80 / 139 )
= 4740 / 19, 460 + 4720 / 19 , 460
= 9460 / 19, 460 = 0.486

4 aii )
Pr one type of fruit is picked
( 79 / 140 * 78 / 139 ) + ( 39 / 140 * 5 p/ 139 )
= 6162 / 19, 460 + 3422 / 19 , 460
= 9584 / 19 , 460 = 0.492

6 b )
h /h +8 = 6 / 10
10 h = 6 h + 48
h = 12
H = h + 8
H = 12 + 8
H = 20
Volume = 1 /3 A . h
= 1 / 3 ( 10 * 10 ) * 20 – 432 / 3
= 200 / 3 – 432 /3

The following has been proving itself very useful in time like this, follow it and and passing the NECO mathematics Exam can never be a problem to you.

#### SET TARGETS AND WORK HARD TO ACTUALISE IT:

You have decided to pass NECO mathematic 2019 and I am sure of that. Now, the next thing you should do is set targets.

You have told yourself, “I will score A in Neco mathematic 2019”, that’s not all. You need to plan how to make it happen. Create a timetable and master plan to achieve your goals.

#### GET MATHEMATIC RECOMMENDED BOOKS FOR NECO 2020:

Normally, Neco recommends books for the examination. But apart from neco literature in English where certain novels are compulsory, you are free to use any good mathematics textbook to prepare for Neco 2020 exam.

Some textbooks are more difficult to understand. If you have any topic you are finding difficult to understand, then get a textbook that will simplify the topics and make life better for you.

DON’T SKIP MATHEMATICS EXAMPLES AND EXERCISES:

Many candidates are fond of skipping exercises and even examples while studying textbooks. In fact, “we” loved notebooks so much that we could ask, “can I read my notebook and pass NECO mathematics 2019?” Don’t be scared of attempting exercises in mathematics. Face the challenges.

SOLVE PROBLEMS IN NECO PAST QUESTIONS:

This is another factor that affects candidates success. Do not read mathematics past questions; answer past questions. Ensure to understand and solve each problem. If you find any question difficult while attempting the maths past questions, then feel free to consult your book for broad knowledge about the topic

### TEST YOURSELF:

This is very important. Once in a while, answer full one-year mathematics past questions on your own without checking the answers. Then mark to see what you score. With this, your confidence is very sure for 2020 NECO mathematics.
