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:
- 3 1/5
- 16 1/5
- 31 1/4
- 4/5
Step-by-step explanation:
An improper fraction is converted to a mixed number by doing integer division and expressing the remainder as a fraction with the divisor as the denominator.
... 19/5 = (3·5 +4)/5 = 3 4/5
The expressions involving exponents are evaluated to mixed numbers according to the Order of Operations. The exponent is evaluated before division, so ...
1. 4^2/5 = (4^2)/5 = 16/5 = 3 1/5
2. 3^4/5 = (3^4)/5 = 81/5 = 16 1/5
3. 5^3/4 = (5^3)/4 = 125/4 = 31 1/4
4. 4^1/5 = (4^1)/5 = 4/5
_____
If you intended fractional exponents, according to the Order of Operations, you need to put that fraction in parentheses. The denominator of the fraction is the root of the base number to the numerator power.
... 4^(2/5) = (4^2)^(1/5) = 16^(1/5) = ![\sqrt[5]{16}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B16%7D)
Do 21/5 x 3/5 and you should get 63/25. Divide 63 by 25 and you should get 2 and 13/25.
