Apharmacist measured 189 ml using a graduated cylinder. based on her experience, the volume did not seem to be correct. this volume was again measured using a calibrated standard device, from which it was determined that the volume of the liquid was actually 225.0 ml. what is the % error in this measurement? (% answer to the nearest tenth)

16%

Step-by-step explanation:

The formula to calculate the percent error is given by :-

Given : A pharmacist measured 189 mL using a graduated cylinder.

i.e. The approximate volume =189 mL

Also,  volume was again measured using a calibrated standard device, from which it was determined that the volume of the liquid was actually 225.0 mL.

i.e. the Exact volume=  225.0 mL

Now, the percent error in this measurement :-

Hence, the percent error in this measurement = 16%

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
