Answer:
1.932 days (or approximatelly 1 day, 22 hours and 22 minutes)
Step-by-step explanation:
The inicial concentration is 60,000, and this concentration triples every 4 days, so we can write the equation:
P = Po * r^t
where P is the final concentration after t periods of 4 days, Po is the inicial concentration and r is the ratio that the concentration increases (r = 3)
Then, we have that:
102000 = 60000 * 3^t
3^t = 102/60 = 1.7
log(3^t) = log(1.7)
t*log(3) = log(1.7)
t = log(1.7)/log(3) = 0.483
so the number of days that will take is 4*0.483 = 1.932 days (or approximatelly 1 day, 22 hours and 22 minutes)
Answer:
the answer is 80 bc 80 is equivalent to the number 80 so this makes the answer 80
Tomatoes 112 acres
corn 152 acres
sunflowers 56 acres
Given:
The system of equations is
To find:
The solution of the given system of equations using the substituting method.
Solution:
We have,
...(i)
...(ii)
From (ii), we get
...(iii)
Putting this value in (i), we get
Multiply both sides by 3.
Putting y=4 in (iii), we get
Therefore, the solution of given system of equations is (0,0).
