d sum of age of the family is 21x14=294, d sum of age of the family when d father age is not counted is 20x12=240, the fada's age is 294-240=54

Tanks u bro,

1. In a test taken by 40 boys nd y girls, the mean scores were 5.5 nd 6 respectively for d boys nd girls. If the total score was 412, the value of y is
A. 38 B. 36 C. 34 D. 32

anza is d.32.,
Total boys score/40 =5.5
Total boys score =220

412-220=192for gurlz total score
192/numba of gurls =6
Y=192/6
Y=32
Answer =D

solve dis pls
-Find a two-digit number such that three times the tens digit is 2 less than twice the units digits and twice the number is 20 greater than the number obtain by reversing the digits (a) 24 (b) 42 (c) 74 (d)47
-Find a positive value of P if the expression 2x^2 – Px + P leaves a remainder 6 when divided by x-p (a) 1 (b) 2 (c) 3 (d) 4
-Find the minimum value of x^2 – 3x – 2 for all real values of x (a) -1/2 (b) -1/4 11.
-A rectangular packet has inner dimension 16cm by 12cm by 6cm. How many cubes of sugar of side 2cm can be neatly packed into the packet (a) 90 (b) 144 (c) 150 (d) 288
-If 2257 is the result of subtracting 4577 from 7056 in base n, find n (a) 8 (b)9 (c) 10 (d) 11

Find a positive value of P if the expression 2x² –Px + P leaves a remainder 6 when divided by x-p

. 2x² - px+p

x-p=0
X=p

2(p)² - p² + p = 6
2p²-p²+p=6
P² + p = 6
P² + p - 6 = 0
P² + 3p - 2p - 6 = 0
(P²+3p) - (2p-6) = 0
P(p+3) -2(p+3) = 0
(P-2)(p+3) = 0
P-2=0 or p+3=0
P=2 or p=-3
Therefore P=2.

Find the minimum value of x² – 3x – 2 for all real values of x

.

x²-3x-2
dy/dx= 0
dy/dx; 2x-3=0
2x=3
x=3/2
x= 1 1/2

A rectangular packet has inner dimension 16cm by 12cm by 6cm. How many cubes of sugar of side 2cm can be neatly packed into the packet

volume of rectangular packet = 16cm * 12cm * 6cm
= 1152cm³
Volume of sugar cube = S³
= (2cm)³
= 8cm³
Number of cubes of sugar that can be neatly packed = 1152cm³ / 8cm³
= 144

If 2257 is the result of subtracting 4577 from 7056 in base n, find n

this one needs no calculation. The operation is in base 8

my workings was so rough but I got 47 at the end of the day.

Good morning, fellow prospective Akokites.

Someone should please roll some more enigma.

P² + p = 6
P² + p - 6 = 0

P(p+3) -2(p+3) = 0
(P-2)(p+3) = 0

I notice say na at the same time people dey flood here and suddenly dem go abscond, together too.

I tire ooo. Me self go soon dey abscond oo.

Uniben thread na d bomb. Una no gree make ours like dem own.

Umartins help me solve this, 1. The line 3y-x=7 makes an angle of tita with the positive x-axis. The value of sin tita is? 2. A boy received a cash gift from his parents on his 10th birthday. On each succeeding birthday, he received twice the amount received in the previous year. If he had received a total of 31,500 by the time he was 15, the cash gift for his 12th birthday was?

The answer is d.
let the no be xy
3x = 2y - 2
3x - 2y= -2 >>>eqn 1
2(10x + y) =10y + x + 20
collect d lyk terms
19x - 8y = 20 >>> eqn 2
subtract eqn 2 from 1
use elimination method
x=4 y=7
the number is 47
