Answer:
It will take 14.3 years
Step-by-step explanation:
Let the consumption of electricity presently be X kw/h
In the next three years, we would be expecting an increase to 3x kw/h
Since we do not know the number of years it will take, let us represent this by t years.
We can represent the consumption in the next three years by the equation;
x × (1 + 8%)^t = 3x
(1+0.08)^t = 3
(1.08)^t = 3
We can use natural logarithms to get what t is
take the natural logarithm of both sides
ln(1.08)^t = ln3
tln1.08 = ln3
t = ln3/ln1.08 = 1.0986/0.077
t = 14.3 years
Answer:
the answer to this is x=16.1
In triangle ABC, angle A is a right angle, and angle B= 45 degrees. (also AC is 12 ft). What is the length of BC? If your answer is not an integer, leave it in simplest rascal form.
Answer:
x = 4°
Step-by-step explanation:
all angles in a triangle sum up to 180°
6x + 38° + 5x + 8° + 90° = 180 °
11x +136° = 180°
11x = 44°
x = 4°
