Answer» Answer: numbers are 120 and 100. Step-by-step explanation: Let no. be X and y. :- x + y = 220 x - y = 20 ATQ- (x + y) + ( x - y ) = 240 2x = 240 x = 240 ÷ 2 x = 120 Therefore, y = 220 - 120 y = 100 Hence, The three digit numbers are= 120 and 100

26.

if x and y are two 3-digit numbers such that ,x+y =220 and the difference between x and y is 20,then find the number.

Answer»

Answer:

numbers are 120 and 100.

Step-by-step explanation:

Let no. be X and y.

:- x + y = 220

x - y = 20

ATQ-

(x + y) + ( x - y ) = 240

2x = 240

x = 240 ÷ 2

x = 120

Therefore,

y = 220 - 120

y = 100

Hence, The three digit numbers are= 120 and 100

40.	Triangle ABC is similar to triangle PQR and 2 x Area of triangle ABC= 3 x Area of triangle PQR, then A(triangle PQR): A(triangle ABC)=_______
Answer» ANSWER: In the example below, the scale factor of triangle ABC to triangle DEF is 2. ... If you MULTIPLY a side from triangle ABC by 2, you GET the LENGTH of the corresponding side of triangle DEF. You can also get 2 as the scale factor by FINDING the ratios: 12/6 = 2, 16/8 = 2, and 18/9 = 2.

Answer»

Answer:

HCF=25

Step-by-step explanation:

given

LCM(a,B)= 45×HCF(a,b)

LCM(a,b)+HCF(a,b)= 1150

replacing LCM to 45×HCF

therefore:

46×HCF(a,b)=1150

HCF(a,b)= 1150/46

HCF(a,b)= 25

√9216= 96

92.16+92.16= 184.32

√184.32= √(18432/100)

= √{(9216×2)/100}
