Answer:
12.12%
Step-by-step explanation:
We have that the formula is given by:
A = p * e ^ (r * t)
From here, we know that A = 200000; p = 20000 and the time we can calculate 40 - 21 = 19
if we replace we have:
200000 = 20000 * e ^ (19 * r)
we must calculate r:
e ^ (19 * r) = 200000/20000
e ^ (19 * r) = 10
19 * r = ln 10
r = ln 10/19
r = 0.1212
In other words, the rate of growth is 12.12%
A;
30 + 8g = c
B;
60 + 3g = c
60 + 3g = 30 + 8 g
30 = 5g
g = 6
6 gigs would have to be used in both for the cost to be the same
Answer:
45%
Step-by-step explanation:
Counting the marbles, there are 5 green, 6 blue and 9 red.
Which means the odds of drawing a red to a non red are 11:9
In fraction form that would be 9 marbles out of 20 are red. 9/20
Since the fraction cannot be simplified, we can go to decimal form.
9/20=.45
.45=45%
The answer is 45%.
