If the left hand and the middle digitsbe interchanged the number is diminished by 180. If the left-hand digit be halved and the middle andright-hand digits be interchanged the number is diminished by 454. Find the number.[Hint. Let the original number be 100a - 106-0, ie, 100a - 106. then, by the first condition(1000 + 106)-(1006 + 10a) = 180 = a-b= 2By the second condition, new number = 100 x = +0 -0 = 50a + b0++2and so (100a+10b)-(50a + b) = 454 = 50a - 9b = 454).

Answer»

ong>Answer:

14.

Step-by-step explanation:

ACCORDING to question:-

2X/3 - X/4 =50

= (8X - 3X) /12= 50

(L.c.m of 3 & 4= 12)

5X =12(50)

5X = 600

X= 600/5

X=120

Hence, the required number is 120

Annual income of JUN Wei= 1600*12=19200

Annual income of Lixin= 6800*12= 81600

Money DONATED by Jun Wei= 1200

Therefore, %age of donation of Jun Wei= 1200/19200*100=6.25%

%age of donation of Lixin= 4500/81600*100= 5.51%

Hence Jun Wei donated higher percentage of his annual income.

48.	Multiply (2y+3)×(4y-2) give answer in step by step
Answer» ONG>Answer: GIVEN: (2y+3) × (4y-2) = 8y²-4y +12y -6 =8y²+8y-6 If you want to find out the ROOTS it will be : 8y²+8y-6 Here, a=8 , b=8 , c=-6 =-b±√b²-4ac/2a =-8±√(8) ²-4(8) (-6) /28 =-8±√64+192/16 =-8±√256/16 =-8±√(16)²/16 =-8±16/16 so, y=-8+16/16 or y=-8-16/16 =8/16=1/2 y= -24/16 =-3/2 so , the required roots are (1/2) and( -3/2)*

Multiply (2y+3)×(4y-2) give answer in step by step

Answer» ONG>Answer:

GIVEN:

(2y+3) × (4y-2)

= 8y²-4y +12y -6

=8y²+8y-6

If you want to find out the ROOTS it will be :

8y²+8y-6

Here, a=8 , b=8 , c=-6

=-b±√b²-4ac/2a

=-8±√(8) ²-4(8) (-6) /2*8

=-8±√64+192/16

=-8±√256/16

=-8±√(16)²/16

=-8±16/16

so, y=-8+16/16 or y=-8-16/16

=8/16=1/2 y= -24/16 =-3/2

so , the required roots are (1/2) and( -3/2)
