Answer:
49/12
Step-by-step explanation:
you multiply the top number by the second top number and the bottom number by the second bottom number so 7 x 7 = 49 and 4 x 3 = 12, so the answer is 49/12
Answer:
2441.95 years
Step-by-step explanation:
We can model this exponencial function as:
P = Po * (1+r)^(t/n)
Where P is the final value, Po is the inicial value, r is the rate, t is the time and n is the period of half-life.
In this case, we have that P/Po = 100% - 25.5% = 74.5% = 0.745, r = -0.5 and n = 5750, so we have that:
0.745 = (1 - 0.5)^(t/5750)
Step 1: log in both sides:
log(0.745) = (t/5750) * log(0.5)
Step 2: isolate t
t = 5750*log(0.745)/log(0.5) = 2441.95 years
A Ratio compares two numbers by division.
The answer is "3 Exponent 4 + 36"
