    1 4/5 × 2 1/3 / 3 3/4 – 4/5 × 2/3
    =9/5 × 7/3 / 18/5 – 4/5 × 2/3
    =21/5 / 18 – 4/5 × 2/3
    =(21/5 ÷ 14/5) × 2/3
    =21/5 × 5/14 × 2/3
    =1


    1b)
    x^2 +5x – 6= 0
    (x^2 + 6x) – ( x– 6) = 0
    x(x+6) –1 ( x+6)= 0
    (x–1) (x +6)= 0
    x – 1 =0 or x+6 = 0
    x=1 or x =– 6

    =====================
    2a)

    161n = 32less down 5
    1×n^2+6×n^1+1×n° = 3× 5^1+2×5°
    n^2 + 6n + 1 = 15 + 2
    n^2 +6n + 1 =17
    n^2 + 6n – 16 = 0
    (n^2 +8n) – (2n – 16) = 0
    n(n + 8) –2 (n + 8) = 0
    (n – 2)(n + 8) = 0
    n – 2 = 0 or n + 8 =0
    n = 2 or n = –8

    hence,
    n = 2

    0.016 × 0.048 / 0.64
    =16 ×10^-3 / 64 × 10^-2
    =16 × 48 × 10^-6 / 64 × 10^-2
    =768 / 64 × 10^-6 × 10^2
    =12 × 10^-4

    =======================

    4)
    h/8 = h + 20/12
    12h = 8h + 160
    4h =160
    h = 160/4
    h =40cm
    Hence ,H =h +20=40 +20 =60cm
    H=60cm

    Volume of bucket =
    1/3πR^2H – 1/3πr^2h
    =1/3π(R^2H – r^2h)
    =1/3(3.142)( (12)^2(60) – (8)^2(40))
    =1/3(3.142)(8640 – 2560)
    =1/3 × 3.142 × 6080
    volume is =6367.7cm^3

    since ,
    1litre = 1000cm^3
    Capacity =6367.7 / 1000
    =6.3677litre
    =6.4litre

    =====================
    5a)
    2/3(x – 2) – x –1/x–2
    =2–3(x –1)/3(x–2)
    =2 – 3x + 3/5x – 6
    =5–3x/3x–6


    5b)
    x^2 + 3x + 2/ x^2 – 4
    =(x^2 + x) + (2x + 2)/(x+2)+(x –2)
    =x(x+1) +2(x+1)/(x+2) +(x – 2)
    = (x+2) (x – 2)/(x+2)(x –2)
    = x+1/x –2

    ====================
    SECTION B
    ANSWER ONLY FOUR QUESIONS
    ===================
    8a)
    if (x – 6), 2x and (8x – 20) are consecutive terms of G.P

    the common ratio is
    r = 2x / x– 2 --------(1)
    r = 8x + 20 / 2x --------(2)

    Equating (1) and (2)
    2x/x – 6 = 8x + 20/2x
    4x^2 = (x – 6) (8x + 20)
    4x^2 = 8x^2 + 20x – 48x – 120
    4x^2 – 28x – 120 = 0
    x^2 – 7x – 30 = 0
    Solving quadratically,
    (x^2 + 3x) – (10x – 30) = 0
    x(x + 3) –10 (x + 3) = 0
    (x - 20) (x + 3) = 0
    x – 10 =0 or x + 3 = 0
    x = 10 or x = -3

    8b)
    √72 × 3√18 × 14√6 / 2√24 ×√12 √36×2 × √9×3 × 24√6 /2√4×6 × √4×3
    6√2 x 9√2 × 14√16 / 4√6 × 2√3
    6 × 9 × 2 × 14 √6 / 4√6 × 2√3
    3 × 9 × 9 / √3
    by rationalizing the denomenator
    = 189/√3 × √3/√3
    =189√3 / 3
    =63√3

    ===================

    x =30° <base angle of issoceless triangle is equal >
    y =θ = 180 – 60
    θ=120° , r = 5cm
    the length of the chord AC
    L =2rsinθ/2
    =2 × 5 × sin120/2
    =10sin60
    =10 × 0.866

    Length of chord is =8.66cm

    9aii)
    Area of shaded segment = area of sector – Area ot triangel
    θ/360 × πr^2 – 1/2 (5)^2sinθ
    =120/360 × 3.142 × (5)^2sin120
    =120 × 3.142 × 25 /360 – 25 × sin120/2
    =26.18 – 10.825
    =15.358cm^2

    9b)

    Speed = Distance / time
    Distance = 500 × 2
    =1000km

    x^2 =(1000)^2 + (450)^2 -2(1000)(450)cos120
    =1000000 + 202500 +450,000
    x^2 =1652500
    x =√1652500
    x = 1285.5km

    The bearing the airport (θ)
    450/sinθ = 1285.5/sin120
    sinθ = 450 × sin120 / 1285.5
    sinθ =0.3032
    θ = sin(0.3032)= 17.6°
    =18°

    blue marble = 3
    white marble = 2
    Red marble = 4/9

    i)
    Pr (both of them will be red)
    first drawn = 4/9
    second drawn = 3/8
    Pr (both red) =4/9 × 3/8
    =1/8

    ii)
    Pr (the two are of the same color)
    = RR or BB or WW
    =(4/9 × 3/8)+ (3/9 × 2/8)+ (2/9×1/8)
    =12/72 + 6/72 + 2/72
    =12+6+2 / 72
    =20/72
    =5/18


    10b)
    sine(2θ – 30°) and (3θ – 45)are supplementary that there sum is 180°
    2θ – 30 + 3θ–45=180
    5θ –75 =180
    5θ=180 + 75
    5θ =225
    θ=51°

    ====================

    11a)

    hence, volume of hemispherical portion is half of the volume of the cone

    Volume of hemisphere=2/3πr^3
    Volume of cone =1/3πr^3
    2/3πr^3 = 1/2(1/3πr^2 h)
    2/3πr^3 = 1/6 πr2 h
    h = 2 × 6 × πr^3 / 3πr^2 = 4r
    h = 4r = 4 × 4 = 16cm
    hence the vertical angle is
    tanθ = r/h
    tanθ = 4/6 = 1/4
    θ =tan(0.25) = 14.036°

    θ =14°(correct to nearest degree)

    11b)
    Total volume of solid

    =1/3πr^2h (h + 2r)
    =1/3 × 22/7 × (4)^2 (16 + 8)
    =1/3 × 22/7 × 16 × 24
    = 22 × 16 × 24 / 21
    = 402.285cm^3

    On the second day , God created the firmament , also called the heavens . He separated the waters above from the waters below . The water above , he called firmament .
    On the third day , God created dry land and vegetation . God commanded the water below to gather at one place and dry land emerged . The dry land he called “ earth ” and the gathering of the water he called “ the ocean ” or the Sea . After that God commanded the earth to bring forth grasses and trees that bore fruits.
    On the fourth day , God created the luminaries . He created the Sun , the Moon and the Stars . The Sun is to rule over the day and the Moon to rule over the night . He said the luminaries should determine the signs , seasons , years and the days.
    On the fifth day , God created the Sea creatures and the birds of the air . Every kind of creature that resides in the Sea , God created . Then every creature that flew in the air was also created .
    On the sixth day , God created four - legged animals and all creeping creatures . On the same day , God created man in His own image . He created both the male and the female on the same day . God blessed the man and woman and asked them to multiply and fill the earth .
    God gave man , as food , the fruit bearing trees . He saw that all the things he had created were good .
    On the seventh day , God rested . He had finished the work of creation . He blessed the day and hallowed it.
    1b)
    i ) God has sovereignty over all of his creations .
    ii) Another nature of God is that when he speaks , things happen .

    ” If you knew the gift of God and who it is that asks you for a drink , you would have asked him and he would have given you living water ”
    Notice that He does not say that He is the living water , but that He would give living water to her , and when she received it, she would never thirst again . Of course, that does not tell us what the living water is! For that , we must go to another passage of Scripture . In this case , Jesus is in the temple surrounded by a throng of worshippers . He suddenly cried out, “ If anyone is thirsty , let him come to me and drink . He who believes in Me , as the Scriptures said , ‘ From his innermost being will flow rivers of living water .’ But thisHe spoke of the Spirit , whom those who believed in Him were to receive ; for the Spirit was not yet given , because Jesus was not yet glorified ”
    3bi )
    By way of contrast Cranfield argues that the reference is not temporal but spatial
    the Kingdom has come near in the person of Jesus .
    3bii)
    That being said , what did Jesus mean by the term Kingdom of God ? The simplest answer is that he used it to summarise
    his entire mission , in all its aspects
    ================================
    4ai )
    To redeem from the captivity of sin all who will believe That night a tattered old women was brought before him for stealing a loaf of bread .
    4aii )
    To receive all who have believed On a day that has already been set by the Lord, JUST A SHORT TIME FROM NOW
    4aiii )
    To recompense judgment to all who have not believed " ’ As surely as I live , ’ says the Lord , ’ every knee will bow before me ;
    every tongue will confess to God .’ "
    4bi )
    For he spake in a certain place ofthe seventh dayon this wise, AndGod did rest the seventh dayfrom all his works .
    4bii)
    And in this place again , If they shallenter into my rest .
    4biii )
    Seeing therefore it remaineth that some must enter therein , and they to whom it was first preachedentered not in because of unbelief :
    4biv )
    Again , he limiteth a certain day , saying in David , To day , after so long a time ; as it is said , To day if ye will hear his voice , harden not your hearts .
    4bv)
    For if Jesus had given them rest , thenwould he not afterward have spoken of another day .
    ================================

    6a )
    Skill acquisition is the ability to be trained on a particular task or function and become expert in it. It is a pity that there is “ huge ” parading of unemployment in many parts of the world today especially in Nigeria . This is giving many youths in different parts of the world today a sleepless night . It is one of the causes of rapid growth in crime in many parts of the world .
    6bi )
    Empowerment has been defined as an individual' s belief in his / her ability to exercise choice. This belief results from the reciprocal impact of the individual 's cognitive style , environmental factors , and behavior .
    6bii)
    Creativity is the act of bringing into existence something which did not exist before . Therefore , creativity may also be said to be reciprocally influenced by a mind set which see possibilities, a perception that the environmental can be impacted , and behavior which produces new things .

    NO1)
    Note:

    Candidates are strongly advised to check which size of pipette was used by their school.

    We used 25cm³

    -------------------------------

    If your school used 20cm³, all you need do is use it in place of 25cm³ anywhere we used it and calculate accordingly

    NOTE:ALL MAKE USE OF YOUR SCHOOL ENDS POINT

    Volume of Pipette used 25.0cm^3

    Titration | Rough | First | Second | Third
    Final burette reading (cm^3) | 22.50 | 45.10 | 32.65 | 27.60
    Intial burette reading (cm^3) | 0.00 | 22.50 | 10.00 | 5.00
    Volume of A used (cm^3) | 22.50 | 22.60 | 22.65 | 22.70

    1a) Average volume of A = 22.60 + 22.65 + 22.70/3

    = 22.65cm^3

    1bi) GIVEN: CB = 0.10moldm^-3
    VB = 25cm^3
    CA = ?
    VA = 22.65cm^3

    Equation of reaction:
    H2C2O4(aq) + 2NaOH(aq) ====> Na2C2O4(aq) + 2H2O(l)
    hence, nA = 1
    Nb = 2

    Using CAVA /CBVB = nA/nB
    CA = CBVBnA/VanB
    =0.10 × 25 × 1/22.65 × 2

    CA = 0.055 moldm^-3

    Concentration of A in moldm^-3 = 0.055


    bii) Using:
    gram concentration = molar concentration × molar mass
    conc. Of A in gdm^-3 = 0.055 × [(1 × 2) + (12 × 2) + (16 × 4)]
    = 0.055 × 90
    = 4.95gdm^-3
