Answer: lenght is 50yrds, width is 30yrds
Step-by-step explanation:
Perimeter of a pool = 2( lenght x breadth)
Perimeter = 160yrds
If the lenght is 10yrds less than twice the width then,
lenght = 2w - 10,
Where w is the width
Then from p = 2(L + w)
160 = 2( 2w - 10 + w)
160 = 2(3w - 10)
160 = 6w - 20
160 + 20 = 6w = 180
width w = 180/6 = 30yrds
From p = 2(L + w)
160 = 2(L + 30)
160 = 2L + 60
160 - 60 = 2L = 100
L = 100/2 = 50yrds

Answer:
15% discount was offered with the family ticket option.
Step-by-step explanation:
So adult is 55 so 55 x 2=110
45 x 2=90
110+90=200 so 170 ( Family ticket )
170 divide by 200=0.85 x 100=85% 100% - 85%=15%
For this case we must simplify the following expression:
We have that by definition of properties of powers that is fulfilled:
Then, rewriting the expression:
