Answer:
$30
Step-by-step explanation:
1 person = $ 2
18 person = 2 × 18 = $36
winner = $6
profit = 36 - 6 = $30
Joint variations occurs when one variable depends on the value of two or more variables. The variable varies directly or indirectly with the other variables combined together. The other variables are held constant. From the given examples, the equation(s) that represent joint variations are
1) z = 3x/y
z varies directly with x and inversely with y.
2) w = abc/4
w varies inversely with a,b and c. 4 is the value of the constant of variation.
So there u go
Answer: 1) After 17.673 years ( Approx) the population will be doubled.
2) After 53.019 years the population will be 80.
Step-by-step explanation:
1) Let x represents the number of years after which the population will doubled,
Since rate of interest = 4%
And, initial number of fish = 10,
Hence the fish after x years = 
⇒ 
⇒ 
⇒ 
⇒ 
Hence, After 17.673 years ( Approx) the population will be doubled.
2) Let after y years the population will be 80.
⇒ 
⇒ 
⇒ 
⇒ 
Hence, After 53.019 years the population will be 80.
220 or 195.
Those options are the most likely.
The least decimal place in 0.045 is found in the thousandths place. Thus, if expressed as a fraction, it would be 45/1000. Let's substitute this to the equation:
x = 45/1000
1000x = 45
(1000/45)x = 1
When you divide 1000 by 45, the quotient would be 22.2222222... This could be round to the nearest whole number which is 22. Then,
22x = 1
x = 1/22
I hope I was able to answer your question. Have a good day.
