Answer:
62.5%
Step-by-step explanation:
the question is worded weirdly but basically since they're saying "<em>given that a state does not use nuclear power</em>", you can ignore the ones that do use nuclear power.
20 + 12 = 32
and then u have to find the percentage that do use coal (20). to do that all you have to do is divide then move the decimal place backwards 2 times
20 ÷ 32 = 0.625
62.5%
Given:
The logarithmic equation is:
To find:
The exponential equation for the given logarithmic equation.
Solution:
We have,
It can be rewritten as:
Using 
, we get
Therefore, the correct option is C.
Delila is correct as she multiplying three negative numbers and determines that the solution will be negative.
As given in the question,
Let the three negative numbers be -x , -y , and -z.
Delia is multiplying three negative numbers
Multiply First two numbers
(-x) (-y) = + x y as (-)(-) = +
Multiply by third numbers
(+x y) (-z) = -x y z as ( +)(-) = -
Therefore, Delila is correct as she multiplies three negative numbers and determines that the solution will be negative.
