Answer:
B. 12.5%
Step-by-step explanation:
Add all the hours together to get 20. We make the assumption that 20 is 100% since it is our output value. We next represent the value we seek with x. From step 1, it follows that 100%=20. In the same vein, x%=2.5.This gives us a pair of simple equations:
100%=20(1)
x%=2.5(2)
By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS (left hand side) of both equations have the same unit (%); we have
=
Taking the inverse (or reciprocal) of both sides gives us this:
>> x=12.5\%
Therefore, 2.5 is 12.5% of 20.
So for this:
(-1/3+-0.3/3+1) ^2
(-1/3-0.1+1)^2
(1-1.3/3)^2
(1-0.433333)^2
0.566667^2
