Answer: 0.000274 dragon fly per day.
Step-by-step explanation:
First convert the 10 years into days:
10 × 365 = 3650 days.
This means that one dragon fly dies every 3650 days.
Now, to find how many that dies in a day:
1 ÷ 3650 = 0.000274, corrected to three significant figure.
Looks more like a probability question.
Answer:
x = 3, x = -2
Step-by-step explanation:
x^2 - x - 6 = 0 could be factored into two binomials:
(x - 3) (x + 2) = 0
solutions are the values of x that get the equation to equal 0 so
x - 3 = 0
x + 2 = 0
Therefore x = 3 and x = 2
Hope that helped : )
Answer:
0.6
Step-by-step explanation:
The x increases by 5, while y increases by 3
Lets use the method, which is .
Keep in mind that x goes horizontally along the axis, while y goes vertically on the axis.
So plug the numbers in.
0.6
Hence, the constant proportionality is 0.6.
Answer:
1432 years
Step-by-step explanation:
A(t) = I(0.5)^t/t1/2
Where t1/2 = half life = 1660
Final amount, A(t) = 0.55 of its original amount =. 0.55I
Hence, we have
0.55I = I(0.5)^t/1660
Take the log of both sides
Log(0.55) = log(0.5)^t/1660
t/1660 = log(0.55) / log(0.5)
t/1660 = 0.8624964
t = 0.8624964 * 1660
t = 1431.7441
t = 1432(nearest whole number)
