Answer:

41ft²

Step-by-step explanation :

3ft * (8ft + 2ft) / 2 = 15ft²

1ft * (8ft + 2ft) = 10ft²

You work in a chemical lab. Last quarter, you successfully completed an average of about 5 chemical analyses per day. This quart
Kryger [21]

Answer: 60%

Step-by-step explanation:

Since, According to the question,  Last quarter, we successfully completed an average of about 5 chemical analyses per day.

Therefore initially our average = 5 chemical analyses per day.

Again, From the question, This quarter, we have increased this average to about 8 per day.

Therefore New average =chemical analyses 8 per day

Thus, Percentage change in the average = (Initial average - New average)×100/ initial average  

= \frac{8-5}{5} \times 100

= \frac{3}{5} \times 100

= 60 %

Therefore, Percentage change in the average=60 %
