Answer:
Month since April Number of Ants
0 10,000
1 30,000
2 90,000
3 270,000
4 810,000
Every month, the ant population triples so the multiply the previous population by 3 to find out the new population.
0 months from April = 10,000 * 1 = 10,000 ants
1 month from April = 10,000 * 3 = 30,000 ants
2 months from April = 30,000 * 3 = 90,000 ants
3 months from April = 90,000 * 3 = 270,000 ants
4 months from April = 270,000 * 3 = 810,000
2(7/2)^x = 49/2
Divide both sides by 2:
(7/2)^x = 49/4
I notice that 49/4 can be rewritten as (7/2)^2, so we now have:
(7/2)^x = (7/2)^2
The only way for this to be true is if x = 2. Thus, we are done.
Answer:
1/36
Step-by-step explanation:
prob of each dice is 1/6
=1/6 * 1/6
Answer:
x = 38
Step-by-step explanation:
using the law of logarithms
• x = n ⇔ x = , hence
(2x - 12) = 3 ⇒ 2x - 12 = = 64
add 12 to both sides
2x = 76 ( divide both sides by 2 )
x = 38
The number is 12.
7 + 5 = 12
12 • 3 = 36
Hope I helped!
