Answer:
Step-by-step explanation:
t + u = 11 ----------- (1 )
10t + u = 10u + t - 9
10t + u - 10u - t = -9
10t - t + u - 10u = - 9
Combine like terms
9t - 9u = -9
Divide the entire equation by 9
t - u = -1 --------------(2)
Add equation (1) & (2) and so, u will be eliminated and we can find the value of t
(1) t + u = 11
(2) <u>t - u = -1</u>
2t = 10
t = 10/2
t = 5
Plugin t = 5 in equation (1)
5 + u = 11
u = 11 - 5
u = 6
The original number is 56

Answer:
The ladder should be 34 feet long.
Step-by-step explanation:
The height of the spotlight above ground = 30 feet
The base of the ladder will be = 16 feet from the base of house
We can easily assume this to be a right triangle with perpendicular as 30 feet and base as 16 feet and we have to find the hypotenuse.
Lets say the length of the ladder or hypotenuse is = x
We will apply Pythagoras theorem here.
=>
=>
=>
So, x = 34
Hence, the ladder should be 34 feet long.
Answer: Consider a power set of real numbers.
The subsets of the power set are as follows:-
1. Natural number()={1,2,3,4,5,....}
2.Whole numbers={0,1,2,3,4,......}
3.Integers()={.......-3,-2,-1,0,1,2,3,....}
4.Rational numbers()=It contains all of the above subsets and fractions (where denominator ≠ 0) ,terminating and repeating decimals.
5.Irrational numbers=It contains numbers which cannot be expressed as the ratio of integers, and they are non-repeating, non-terminating decimals.
