1/2 x s, where s equals 3/10 means,
(1/2) x (3/10) which will give (3/20)
You simply multiply the numerators to get 3 and the denominators to get 20.

1. The growth rate equation has a general form of:
y = A (r)^t
The function is growth when r≥1, and it is a decay when
r<1. Therefore:
y=200(0.5)^2t                    -->
Decay
y=1/2(2.5)^t/6                  -->
Growth
y=(0.65)^t/4                       -->
Decay
 
2. We rewrite the given equation (1/3)^d−5 = 81
 
Take the log of both sides:
(d – 5) log(1/3) = log 81
d – 5 = log 81 / log(1/3)
d – 5 = - 4
 
Multiply both sides by negative 1:
- d + 5 = 4
So the answer is D
 
        
             
        
        
        
Answer:
There was a increase of 1.7% over these three years
Step-by-step explanation:
Multipliers:
For a decrease of a%, we multiply by: 
For a increase of a%, we multiply by: 
What was the percentage increase/decrease of groundhogs over these three years? 
Decrease of 12%(multiplication by 0.88).
Increase of 6%(multiplication by 1.06).
Increase of 9%(multiplication by 1.09).
After these three years:
0.88*1.06*1.09 = 1.017
1.017 - 1 = 0.017
0.017*100% = 1.7%
There was a increase of 1.7% over these three years
 
        
             
        
        
        
5 out of 20 like Star Wars so what value (x) should like Star Wars out of 200. Set up a proportion comparing the two. 
x= # of people in 7th gr who like Star Wars
5/20= x/200
cross multiply 
(5*200)= (20*x) 
1000= 20x
divide both sides by 20
50= x
ANSWER: 50 people in the 7th grade should like Star Wars. 
Hope this helps! :)
