Answer:
a) P(t) = 330 
b)P(t) →population after t years.
t →number of years.
c) Number of deer after five years = 556
Step-by-step explanation:
a) The population increasing at an annual rate of 11%, means the population is being multiplied by 1.11 each year.
So, we can use the formula
P(t) = P 
P(t) = 330 
P(t) = 330 
b) In this model
P(t) → population after t years
P → present population
r → annual increasing rate
c) Number of population after 5 years is,
P(5) = 330 
= 556
Number of deer after 5 years = 556
Because the sofa usually sells for $800, we know that's 100% of the price.
100% = $800
Let's find 1%.
1% = $800/100
1% = $8
Next, multiply $8 by 75 to find the percent of the sofas price when it's $600.
75% = $600
We now know that $600 is 75% of the sofas original price.
100% - 75% = 25%
The percent of decrease I'm the sofas sale price is 25%.
Hope I got that right, the question was worded a little strangley so I wasn't quite sure what you were asking :)
Answer:
Find the unit rate of each printing machine and compare.
Step-by-step explanation:
Answer:
4ab² + 20b - 3a
Step-by-step explanation:
This question most likely asks us to simplify the expression, as factoring is not possible...
(ab² + 13b - 4a) + (3ab² + a + 7b),
ab² + 13b - 4a + 3ab² + a + 7b,
ab² + 3ab² + 13b + 7b - 4a + a,
Solution : 4ab² + 20b - 3a
