The length is 0.5 and your welcome the explanation is long but this is the answer
2 x 5/ 50 x 18
10 / 900
Divide both by 10
1/90
Answer 1:
It is given that the positive 2 digit number is 'x' with tens digit 't' and units digit 'u'.
So the two digit number x is expressed as,


The two digit number 'y' is obtained by reversing the digits of x.
So, 

Now, the value of x-y is expressed as:




So,
is equivalent to (x-y).
Answer 2:
It is given that the sum of infinite geometric series with first term 'a' and common ratio r<1 = 
Since, the sum of the given infinite geometric series = 200
Therefore,
Since, r=0.15 (given)



a=170
The nth term of geometric series is given by
.
So, second term of the series =
= ar
Second term = 
= 25.5
So, the second term of the geometric series is 25.5
Step-by-step explanation:
Y-5= 3(x-0)
Y-5= 3x
Y= 3x + 5
Hope this helps!
Answer:
Step-by-step explanation:
Huilan = H
Thomas = T
H = 3T
T+3T = 40(This is the sum)
4T = 40
4T/4=T
40/4=10
T=10
