Answer:
Dividing a power of 4 by 4 is equivalent to ( reducing,) the exponent by (1).
Step-by-step explanation:
Let the power of 4 be 3
4 *4*4
We divide by 4
4*4*4/4 = 4*4 = 4^2
So we removed 1 power
Notice that 3-1 =2
Let 4 be raised to any power
4^a
We divide by 4
4^a/4 we remove 1 of the powers
we are left with
4^(a-1)
So we reduce the exponent by 1
Answer:
3.1%
Step-by-step explanation:
From the question, Ramon earns $1735 monthly
He pays $53.10 for electricity
% of Ramon’s salary spent on electricity each month will be
Amount spent on electricity divided by his monthly earning multiplied by 100%.
That is $53.10/$1735 x 100%
=0.0306 x 100
= 3.06%
To the nearest tenth, it becomes 3.1%
So, Ramon spends 3.1% of his monthly earnings on electricity
