Answer:
$3063.6
Step-by-step explanation:
72% of $4,255 = $3063.6
The formula for finding percents is number x percent ÷ 100. 
4,255 x 72 ÷  100 = 3063.6
 
        
             
        
        
        
Answer:
2,674.14 g
Step-by-step explanation:
Recall that the formula for radioactive decay is 
N = N₀ e^(-λt)
where, 
N is the amount left at time t
N₀ is the initial amount when t=0, (given as 42,784 g)
λ = coefficient of radioactive decay
   = 0.693 ÷ Half Life
   = 0.693 ÷ 18
   = 0.0385
t = time elapsed (given as 72 years)
e = exponential constant ( approx 2.7183)
If we substitute these into our equation:
N = N₀ e^(-λt)
= (42,787) (2.7183)^[(-0.0385)(72)]
= (42,787) (2.7183)^(-2.7726)
=  (42,787) (0.0625)
= 2,674.14 g
 
        
             
        
        
        
Let x= cucumber plants
5x= tomato plants
6x+7= pepper plants
peppers = 19  
therefore 
6x+7=19
subtract 7 from both sides 
6x= 12
 divide both sides by 6 
x=2
replace the x with 2
2= cucumber plants
10= tomato plants
hope this helps
