Need help with #11! Thanks :))

  57

Step-by-step explanation:

In terms of weeks, the exponential equation for population can be written as ...

  P(t) = P(0)·2^(t/6) . . . . . . the multiplier is 2 every 6 weeks

For the given initial population, P(0) = 9, we have ...

  P(t) = 9·2^(t/6)

__

For t = 112 days, we need to convert to weeks.

  t = (112 days)/(7 days/week) = 16 weeks

Then ...

  P(16) = 9·2^(16/6) ≈ 57.146

The population in 112 days is about 57 rabbits.

sorry, can't i suggest going to algebra.com

step-by-step explanation:

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
