Answer:
the answer is 1.453
Step-by-step explanation:
i am not sure about the answer but here are my steps. first he says in the 1990s there was a deforestation rate of about 0.48%per year. and 1 is the rate of land that is shrinking. this means that if Brazil had a forest of area x then
x(0.48%)=1 therefore x=2.083
lets use that in this equation
the area left (the final answer) 2.083(0.48)^35= 1.453
(i asked about the unit its measured with because if it is measured by thousands of squared meters or kilometers just big unit measured to be exact my answer would be correct)
Answer: b. $22.75
Step-by-step explanation:
Given : A large pizza with no toppings costs $14.00. A large pizza with 2 toppings costs $17.50.
Let x denotes the number of toppings and y be the cost of that pizza.
Then,
, m= cost per topping and c= cost of pizza without any topping.
From the given information.
c= $14
Function of cost becomes = 
For x= 2 and y= 17.50, we have

tex]3.50=m(2)[/tex] [Subtract 14 from both sides]
[Divide both sides by 2]
For c= 14 and m =1.75 , our function becomes.

Now, for x= 5

Hence, the cost of a pizza with 5 toppings = $22.75
