Answer:
children's: 111 and adults: 62
Explanation:
- given total number of people 173
- total amount received is $306
- during the process, we shall consider x as children and y as adult
make equations:
x + y → 173 [ this was from total people ]
1.5x + 2.25y → $306 [ this was from cost ]
try to make x the subject:
x + y → 173
x → 173 - y ______equation 1
1.5x + 2.25y → $306
1.5x → 306 - 2.25y
x → 
__________equation 2
solve them simultaneously:
= 173 - y
306 - 2.25y = 259.5 - 1.5y
-2.25 + 1.5y = 259.5 - 306
-0.75y = -46.5
y = 62
so there were total 62 adults that day in the public swimming pool.
find children's using:
x → 173 - y
x → 173 - 62
x → 111
so there were total 111 children's that day in the public swimming pool.
Answer:
Irrational, rational, rational, rational, irrational
Step-by-step explanation:
Pi is irrational, so anything multiplied by it is irrational also. The square root of 25 is just 5 or -5, both of which are rational. 17/12 is a fraction of integers so it's rational. 41.4141... is a repeating decimal so it is rational. And the square root of 7 is a random decimal, so it is irrational.
