Let d represent number of days and n represent number of workers.
We have been given that when building a house, the number of days required to build varies inversely with with the number of workers.
We know that the equation 
represents the relation where y is inversely proportional to x and k is the constant of proportionality.
So our required equation would be 
Upon substituting our given values, we will get:
Since constant of proportionality is 665, so our equation would be 
.
To find the number of days it will take to build a similar house with 5 workers, we will substitute 
in our equation as:
Therefore, it will take 133 days for 5 workers to build a similar house.
Answer:
$870
Step-by-step explanation:
To figure out how much the final value here is, use the formula A = P(1 + rt). (A = total accured amount, P = principal, r = rate (%), t = time (years))
A = 600 * (1 + (10 * 9/200)) (multiply 10 by 9 and put that over 200)
A = 600 * (1 + (90/200)) (90/200 simplifies to 9/20)
A = 600 * (1 + (9/20)) (add 1 (20/20) to 9/20 to get 29/20)
A = 600 * 29/20 (Multiply 600 by 29 and put that over 20)
A = 17400/20 (Divide 17400 by 20 to get 870)
A = 870
$870 is the final value.
Answer:
7/4
Step-by-step explanation:
The answer is ether 25 or 50 I think.
X + (x + 2) + (x + 4) + (x + 6) = 156
x + x + x + x + 2 + 4 + 6 = 156
4x + 12 = 156
- 12 - 12
4x = 144
4 4
x = 36
x = 36
x + 2 = 38
x + 4 = 40
x + 6 = 42
